SMA4F100A Description

Short technical summary and product information.

The SMA4F100A is a unidirectional transient voltage suppression (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The device features a stand-off voltage of 100 V and a breakdown voltage of 11.1 V at 10 mA.

 

Key electrical specifications include a peak pulse power dissipation of 400 W for a 10/1000 µs pulse and 2.5 kW for an 8/20 µs pulse. The clamping voltage is 16.2 V at 10/1000 µs, with a peak pulse current of 24.7 A for the same pulse condition. The device also offers ESD protection up to 25 kV (contact) and 30 kV (air) per IEC 61000-4-2.

 

The SMA4F100A is housed in a surface-mount DO-221AC (SMA Flat Leads) package, suitable for automated assembly. It has an operating junction temperature range of -55°C to 175°C and features matte tin plating on its leads.
