1KSMB68CA Description

Short technical summary and product information.

The Littelfuse 1KSMB68CA is a bidirectional Zener TVS diode designed to protect sensitive electronic equipment from voltage transients. It offers a reverse standoff voltage of 58.1V and a clamping voltage of 92V, with a peak pulse power capability of 1000W (10/1000μs waveform). The breakdown voltage is 68V (inferred from the part number). Peak pulse current is 10.9A, and the device features a response time of less than 1.0ps from 0V to breakdown voltage minimum.

 

The 1KSMB68CA is housed in a surface-mount DO-214AA (SMB) package, with gull-wing terminations. It is rated for operating temperatures from -55°C to 150°C (junction temperature). Thermal resistance is 20°C/W from junction to lead and 100°C/W from junction to ambient. The device is halogen-free, RoHS3 compliant, and MSL level 1.

 

Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The 1KSMB series bridges the gap between 600W and 1.5kW surge ratings in a compact package.
