STMicroelectronics 1-Element Uni-Directional TVS Diode, 1.5 kW, 2-Pin DO-201 1.5KE440A

STMicroelectronics 1.5KE440A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transient surges. With a peak pulse power dissipation of 1.5 kW, it delivers robust protection, clamping high voltage transients to safe levels. Its DO-201 through-hole package with 2 pins simplifies mounting on printed circuit boards.

This TVS diode provides a minimum breakdown voltage of 418 V and a maximum reverse stand-off voltage of 376 V, allowing it to withstand and suppress damaging voltage surges effectively. It operates reliably over a wide temperature range from -65°C to +175°C, making it suitable for industrial, automotive, and consumer electronics applications exposed to harsh environments.

Featuring a maximum peak pulse current of 13 A and a clamping voltage of 776 V, the device ensures rapid response to voltage transients, protecting downstream components. Its compact size with a length of 9.5 mm and diameter of 5.3 mm enables integration into space-constrained designs. Low leakage current (max 1 μA) ensures minimal power consumption during normal operation.

Typically used in power supplies, communication equipment, automotive electronics, and industrial control systems, the 1.5KE440A TVS diode safeguards circuits against electrostatic discharge (ESD), inductive load switching, and other transient events that can damage semiconductor devices.

Key features include its single diode configuration, uni-directional direction type, and adherence to standard DO-201 packaging. The product is designed for through-hole mounting, providing robust mechanical and electrical stability on the PCB.

STMicroelectronics’ Transil™ series continues to be widely trusted for its performance and reliability in transient voltage suppression. This diode is compliant with general semiconductor standards and designed to reliably protect sensitive electronics in demanding operational environments.
