1.5SMC24A Description

Short technical summary and product information.

The 1.5SMC24A is a 1500W peak pulse power TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a reverse standoff voltage of 20.5V and a clamping voltage of 33.2V at a peak pulse current of 45.8A.

 

This unidirectional device is housed in a DO-214AB (SMC) surface mount package, offering a compact solution for circuit protection. It operates over a junction temperature range of -65°C to 150°C and is rated for ESD protection up to 30kV air and contact discharge per IEC 61000-4-2.

 

The 1.5SMC24A is suitable for protecting I/O interfaces, VCC bus lines, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic applications. Its low profile package and built-in strain relief facilitate reliable surface mount assembly.
