TV04A121JB-G Description

Short technical summary and product information.

The TV04A121JB-G is a 400W Zener TVS diode manufactured by Comchip Technology. It features a reverse standoff voltage of 120V and a maximum clamping voltage of 193V at a peak pulse current of 2.07A. The device is unidirectional and provides general-purpose transient voltage suppression.

 

This TVS diode is housed in a DO-214AC (SMA) surface-mount package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. The component is RoHS3 compliant and REACH unaffected, though these compliance claims are unverified.

 

The part is intended for general-purpose circuit protection applications where a 400W peak pulse power rating is sufficient. Its compact SMA package makes it suitable for space-constrained designs on printed circuit boards.
