1KSMBJ33A Description

Short technical summary and product information.

The 1KSMBJ33A is a 1000W surface mount transient voltage suppressor diode from Littelfuse's 1KSMBJ series. It utilizes glass passivated junction technology for high surge capability. The device offers a reverse standoff voltage of 28.2V, a nominal breakdown voltage of 33V, and a clamping voltage of 45.7V at a peak pulse current of 22A (10/1000µs waveform). It has a peak pulse power rating of 1000W (10x1000µs double exponential waveform).

 

This TVS diode is designed for telecom and automotive applications, providing fast response time (<1 ps) and low clamping factor. The unidirectional device has a single anode configuration. It operates over a junction temperature range of -55°C to 150°C.

 

The device is packaged in a DO-214AA (SMB) surface mount package, supplied on tape and reel in quantities of 3000 pieces. The case material is UL 94 V-0 rated molded plastic, with solderable terminals per MIL-STD-750. The part is RoHS compliant and UL recognized (File E128662).
