1.5SMC300A Description

Short technical summary and product information.

The 1.5SMC300A is a unidirectional TVS diode from Littelfuse's 1.5SMC series. It is designed for 256V reverse standoff voltage and provides a clamping voltage of 414V at a peak pulse current of 3.7A. The device can handle 1500W peak pulse power (10/1000µs waveform). It features ESD protection up to 30kV air and contact per IEC 61000-4-2. The package is DO-214AB (SMC) for surface mount applications. Operating temperature range is -55°C to 150°C. The device is halogen-free and RoHS compliant.

 

Typical applications include general purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The response time is less than 1.0ps. The device offers low incremental surge resistance and excellent clamping capability.
