STMicroelectronics 1-Element Bi-Directional TVS Diode 1.5 kW 2-Pin DO-201 1.5KE400CA

STMicroelectronics 1.5KE400CA is a 1-Element Bi-Directional Transient Voltage Suppressor (TVS) Diode featuring a peak pulse power dissipation of 1.5 kW and designed in a 2-pin DO-201 cylindrical package for through-hole mounting. This device is engineered to protect sensitive electronic circuits from voltage transient spikes induced by inductive load switching and lightning surges.

The diode configuration is bi-directional, allowing it to suppress voltage transients in both forward and reverse bias, making it ideal for AC and DC applications where bidirectional protection is required.

Key electrical parameters include a minimum breakdown voltage (Vbr) of 380V and a maximum reverse stand-off voltage (Vwm) of 342V, ensuring the diode clamps voltage surges effectively below damaging levels. The device has a clamping voltage (VC) of 706V and a maximum peak pulse current (Ippm) of 14A, capable of absorbing high energy transients.

Physically, the diode comes in a DO-201 package with dimensions measuring 9.5mm in length and 5.3mm in diameter. This robust package type is suitable for through-hole PCB mounting applications. The operating temperature range is broad, from -65°C to 175°C, allowing reliable performance in various harsh industrial, automotive, and electronic environments.

With a low maximum reverse leakage current of 1µA, the diode efficiently reduces power consumption during normal operation. The single element per chip design optimizes transient voltage suppression, contributing to the device's fast response time and durability.
