2KBP02M

onsemi 2KBP02M Overview

The 2KBP02M is a high-performance bidirectional transient voltage suppressor (TVS) diode from onsemi, designed to protect electronic circuits from voltage spikes caused by electrostatic discharge (ESD), electrical fast transients (EFT), and other surge events. It provides effective protection for sensitive electronic components, ensuring the longevity and reliability of systems exposed to such disturbances. The device is particularly suitable for use in communication systems, automotive electronics, consumer electronics, and industrial applications where protection from overvoltage transients is critical.

### Key Features

* Bidirectional Operation: The 2KBP02M is a bidirectional device, meaning it can protect against both positive and negative voltage spikes. This is particularly useful for systems with AC or differential signal lines, where transients could occur in either direction.

* Low Clamping Voltage: One of the key features of the 2KBP02M is its low clamping voltage, which ensures that it absorbs transient energy without letting excessive voltage pass through to the protected circuit. This minimizes the risk of damage to sensitive components.

* Fast Response Time: The device has an extremely fast response time, allowing it to react almost instantaneously to voltage spikes. The typical response time is <1ns, which is essential for protecting circuits from fast transients.

* High Power Handling: The 2KBP02M can handle transient voltages up to 600W (8/20μs pulse), making it ideal for protecting against large surge events commonly encountered in power lines and data lines.

* Compact Package: The device comes in a DO-204AL (DO-15) package, which is compact and suitable for space-constrained designs while offering excellent power dissipation.

* Low Capacitance: With its low capacitance characteristics, the 2KBP02M ensures minimal impact on the performance of high-frequency circuits, making it ideal for protecting communication lines and data transmission systems.

### Electrical Specifications

* Working Voltage (V\_RWM): The maximum working voltage of the 2KBP02M is 24V, meaning that the device can safely handle continuous voltages up to this value without degradation in performance.

* Clamping Voltage (V\_C): The typical clamping voltage at a surge current of 1A is 45V, while at 5A it is typically 80V. This low clamping voltage ensures that the device can absorb significant transient energy while preventing high voltage from reaching the protected components.

* Peak Pulse Power (P\_PP): The 2KBP02M can absorb up to 600W of peak pulse power for an 8/20μs waveform, providing robust protection against high-energy surges.

* Reverse Stand-Off Voltage (V\_R): The reverse stand-off voltage of the device is 24V, which means the diode will not conduct in reverse voltage conditions under normal operating conditions, ensuring that only transient events trigger the protective mechanism.

* Clamping Voltage at 1A: The typical clamping voltage is 45V, and at 5A, it is 80V, ensuring that it provides a high level of protection against overvoltage events.

* Capacitance (C\_j): The capacitance is typically 30pF at a reverse voltage of 0V and a frequency of 1MHz. This low capacitance ensures that the device has minimal impact on high-frequency signals, making it suitable for high-speed communication and data systems.

* Response Time: The device reacts very quickly to overvoltage conditions, with a typical response time of <1ns, ensuring that transients are suppressed immediately, preventing damage to the protected circuit.

### Mechanical and Package Specifications

* Package Type: The 2KBP02M is housed in a DO-204AL (DO-15) package, a widely used small-outline package that provides a compact solution for transient voltage suppression.

* Package Dimensions: The DO-204AL package has dimensions of 4.5mm x 9.5mm, making it suitable for compact designs and systems with space constraints.

* Operating Temperature Range: The 2KBP02M operates over a wide temperature range, typically from -40°C to 125°C, allowing it to function reliably in harsh environments and industrial applications.

* Storage Temperature: The device can be stored at temperatures between -40°C and 150°C, making it suitable for use in systems with varying environmental conditions.

### Applications

* Communication Systems: The 2KBP02M is widely used in communication systems, including telephone lines, Ethernet ports, and wireless infrastructure, where protection against ESD and surge events is essential. Its low capacitance and fast response time ensure that it does not interfere with signal integrity.

* Automotive Electronics: Automotive systems, including in-vehicle communication networks, sensors, and power management systems, often experience transient voltage events. The 2KBP02M provides robust protection for these critical systems, helping prevent damage caused by spikes from the battery, alternator, or external sources.

* Consumer Electronics: In consumer electronics, such as TVs, home appliances, and computing devices, transient voltage spikes can occur due to power surges or lightning strikes. The 2KBP02M is used to protect sensitive components such as microcontrollers, memory chips, and communication interfaces.

* Industrial Equipment: Industrial control systems, automation equipment, and machinery are often exposed to high-voltage transients caused by switching operations, motors, or external disturbances. The 2KBP02M provides effective protection in such environments.

* Power Supply Systems: The device is ideal for protecting power supply lines and power-sensitive circuits from surges and spikes that can originate from external sources like the grid or lightning strikes.

* Data Line Protection: The 2KBP02M is commonly used in data lines, such as USB, HDMI, and Ethernet, to safeguard against ESD, EFT, and other surge events, ensuring that digital communication remains uninterrupted and reliable.
