5.0SMDJ12A Description

Short technical summary and product information.

The 5.0SMDJ12A is a 5000W peak pulse power TVS diode from Littelfuse, part of the 5.0SMDJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events.

 

This unidirectional Zener diode has a reverse standoff voltage of 12V, a clamping voltage of 19.9V, and a peak pulse current of 252A. It offers ESD protection up to 30kV (air and contact) per IEC 61000-4-2 and has a fast response time of less than 1.0ps.

 

The device is housed in a surface mount DO-214AB (SMC) package with a supplier device package of DO-214AB (SMCJ). It operates over a temperature range of -65°C to 150°C. Typical applications include telecom, I/O interfaces, VCC bus, and other vulnerable circuits.

 

The 5.0SMDJ12A is RoHS3 compliant, halogen free, and has a moisture sensitivity level of 1 (unlimited). It is also REACH unaffected.
