1.5KE400CA Description

Short technical summary and product information.

The 1.5KE400CA is a transient voltage suppression (TVS) diode designed for protecting sensitive electronic circuits from overvoltage transients. It features a peak pulse power dissipation of 1500W at TA=25°C with a 1ms pulse width (non-repetitive). Steady state power dissipation is rated at 5W when the lead temperature is maintained at 75°C, with proper mounting on a copper leaf area of 0.79 in² (20 mm²) for thermal management.

 

This TVS diode can handle a peak forward surge current of 200A for an 8.3ms half sine-wave (single pulse), with a duty cycle limited to 4 pulses per minute maximum. The operating and storage temperature range is -65°C to +175°C, ensuring reliable performance in harsh environments. Peak pulse power derates above TA=25°C per the derating curve in the datasheet.

 

Suitable for use in power supply transient protection, automotive electronics, telecommunication systems, and industrial equipment, the 1.5KE400CA provides robust overvoltage clamping. The exact package type is not specified in the available data, but the part is typically available in an axial leaded package.
