1.5SMC200A Description

Short technical summary and product information.

The 1.5SMC200A is a surface mount unidirectional TVS diode from Littelfuse's 1.5SMC series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It offers a peak pulse power dissipation of 1500W (10/1000μs waveform) and a clamping voltage of 274V at a peak pulse current of 5.5A.

 

This device features a reverse standoff voltage of 171V and a minimum breakdown voltage of 190V. It is capable of handling a peak forward surge current of 200A (8.3ms single half sine wave) and has a maximum instantaneous forward voltage of 3.5/5.0V at 100A for unidirectional operation. The operating junction temperature range is -65°C to 150°C.

 

The 1.5SMC200A is housed in a DO-214AB (SMC) package, suitable for surface mount applications to optimize board space. It is RoHS3 compliant and has an MSL of 1 (unlimited). Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
