1.5KE200CA Description

Short technical summary and product information.

The 1.5KE200CA is a bidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It features a glass passivated chip junction in a DO-201 axial leaded package, offering fast response time typically less than 1.0 picosecond from 0V to breakdown voltage.

 

Key electrical specifications include a reverse standoff voltage of 171V, a maximum clamping voltage of 353V at peak pulse current, and a peak pulse power dissipation of 1500W (10/1000μs waveform). The device can handle a peak pulse current of 28A under the same waveform. Steady state power dissipation is 6.5W at 75°C lead temperature on infinite heat sink.

 

The TVS diode operates over a junction temperature range of -55°C to 175°C and features typical thermal resistance of 15°C/W junction-to-lead and 75°C/W junction-to-ambient. It is lead-free (Pb-free E3), RoHS3 compliant, and halogen free. Applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
