SMA4F154A Description

Short technical summary and product information.

The STMicroelectronics SMA4F154A is a unidirectional TVS diode from the SMA4F series, designed to protect sensitive electronic circuits from transient voltage surges. It operates with a stand-off voltage range and offers robust protection capabilities.

 

Key electrical characteristics include a breakdown voltage of 154V and a clamping voltage of 246V at a peak pulse current of 1.6A (10/1000 μs). The diode can handle a peak pulse power of 400W for 10/1000 μs pulses and 2.5kW for 8/20 μs pulses. It maintains low leakage current, with values of 0.2 μA at 25 °C and 1 μA at 85 °C, ensuring minimal impact on circuit performance.

 

This TVS diode is built using planar technology, contributing to its reliability and stability, especially in high-end circuits requiring high junction temperatures. The operating junction temperature range is from -55 °C to +175 °C, with a maximum storage temperature of +175 °C.

 

The SMA4F154A is housed in a DO-221AC, SMA Flat Leads package, suitable for surface mount applications. Its lead finishing is matte tin plating. The device complies with various industry standards, including UL94 V0 and J-STD-020 MSL level 1.
