The 5KP40A-E3/54 is a 5kW unidirectional TVS (Transient Voltage Suppression) diode manufactured by Vishay Dale. It is designed to protect sensitive electronics from voltage transients induced by lightning, inductive load switching, and electrostatic discharge. The device features a reverse standoff voltage of 40V, a typical clamping voltage of 64.5V, and a peak pulse current capability of 77.5A (8/20µs waveform). With a peak pulse power rating of 5000W (5kW), it provides robust protection for general-purpose applications.
This TVS diode is unidirectional, making it suitable for DC power supply lines and signal lines where the voltage is always positive. It does not include power line protection features, indicating it is intended for secondary protection or low-power applications. The operating junction temperature range spans from -55°C to 175°C, allowing reliable operation in harsh environments.
The device is packaged in a P600 axial through-hole package, which facilitates easy mounting on printed circuit boards. The axial termination style is suitable for through-hole soldering. The package is also known as the P600 case, which is a standard size for high-power TVS diodes.
Compliance with RoHS3 and REACH is indicated, though these claims are unverified. The part is also available in tape and reel packaging (DigiKey part numbers 5KP40A-E3/54GITR-ND and 5KP40A-E3/54GICT-ND).
