SMF12A Description

Short technical summary and product information.

The SMF12A is a Zener-type transient voltage suppression diode from Littelfuse. It is designed for general purpose circuit protection in surface mount applications. The device features a reverse standoff voltage (Vrwm) of 12V and a clamping voltage (Vc) of 19.9V, capable of handling peak pulse currents up to 10.1A. With a peak pulse power rating of 200W, it provides reliable overvoltage protection for sensitive electronics.

 

Packaged in the compact SOD-123F form factor, the SMF12A supports surface mount assembly and occupies minimal board space. It operates over a junction temperature range of -55°C to 150°C. This component is unidirectional with one protection channel and does not include power line protection.

 

Common applications include protection of I/O interfaces, VCC buses, and other vulnerable circuits in portable devices, consumer electronics, and power supplies. The SMF12A is a direct replacement for parts in the same SMF series.
