Introduction to TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are an essential component of voltage regulation and protection systems in a range of different applications. These devices act like a short circuit when a voltage spike or surge exceeds the device rating, diverting the current to ground and protecting the circuit from damage. TVS diodes can withstand much higher voltage shocks than other protective components such as fuses, making them ideal for use in high-voltage applications.

5KP24AHE3/73 Application Field and Working Principle

The 5KP24AHE3/73 is a 600 Watt (W) unidirectional TVS Diode released by Littelfuse, a market leader in circuit protection and sensing solutions. This device is designed for 24V automotive applications and suitable for use in DC-DC converters, in-vehicle networking and telecommunications equipment. The 5KP24AHE3/73 offers a wide operating temperature range from -40°C to 125°C and a Reverse Standoff Voltage (BVS) of 28 Volts (V).The working principle of the 5KP24AHE3/73 is quite simple. When the voltage spike exceeds the BVS, the diode will become conductive and allow current to flow from Cathode (-) to Anode (+). This reduces the voltage across the protected application to safe levels, protecting it from damage. The device is then instantly reversed back to its non-conducting state. This ensures that the protected circuit is not affected by repeated voltage spikes or surges.

Features and Benefits

The 5KP24AHE3/73 has several features and benefits that make it an ideal solution for 24V automotive applications. These include:- High peak power rating of 600W, making it suitable for rapid transients, such as those caused by relay coil switching- Low stand-off voltage, enabling safe operation at low voltage levels- Highly reliable and effective protection, with a breakdown voltage higher than the BVS- High capacitance over a wide temperature range ensuring fast response to transient sources- Suitable for use in DC-DC converters and in-vehicle networking and communication equipment

Conclusion

The 5KP24AHE3/73 is a reliable and effective TVS diode designed for 24V automotive applications. This device offers high peak power rating of 600W for reliable protection against voltage spikes and surges, and boasts a low stand-off voltage for safe operation at low voltage levels. Furthermore, its high capacitance over a wide temperature range ensures fast response to transient sources, making it suitable for use in DC-DC converters and in-vehicle networking and communication equipment.
