1KSMB15CA Description

Short technical summary and product information.

The 1KSMB15CA is a 1000W bidirectional TVS diode from Littelfuse, part of the 1KSMB series designed to protect sensitive electronic equipment from voltage transients. It offers a reverse standoff voltage of 12.8V and a clamping voltage of 21.2V at a peak pulse current of 47.2A (10/1000μs waveform). The device features a fast response time of less than 1.0ps and excellent clamping capability. It is suitable for general purpose applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The diode is housed in a surface mount DO-214AA (SMB) package, optimized for board space. It is RoHS compliant, halogen free, and meets MSL level 1 per J-STD-020. Operating temperature range is -55°C to 150°C (junction).
