SMA4F10A Description

Short technical summary and product information.

The STMicroelectronics SMA4F10A is a TVS (Transient Voltage Suppressor) diode from the SMA4F series, engineered to safeguard sensitive electronic circuits against transient voltage spikes. This unidirectional device offers a peak pulse power dissipation of 400W for a 10/1000 μs waveform and 2.5 kW for an 8/20 μs waveform.

 

With a standoff voltage range from 5V to 188V, the SMA4F10A is suitable for a variety of applications. It exhibits low leakage current, with values of 0.2 μA at 25 °C and 1 μA at 85 °C, contributing to long-term reliability and stability. The operating junction temperature range is from -55 °C to +175 °C.

 

Packaged in a DO-221AC, SMA Flat Leads (SMAflat) package, this TVS diode is designed for surface mounting. Its planar technology ensures compatibility with high-end circuits requiring robust protection against voltage transients.
