1SMA54AT3G Description

Short technical summary and product information.

The 1SMA54AT3G is a unidirectional TVS (Transient Voltage Suppressor) diode manufactured by On Semiconductor. It is designed to protect sensitive electronics from voltage transients and ESD events. This device features a reverse standoff voltage of 54V and a clamping voltage of 87.1V at a peak pulse current of 4.6A.

 

With a peak pulse power rating of 400W (10/1000μs waveform), it provides robust protection for general purpose applications. The diode has a typical capacitance of 240pF at 1MHz, making it suitable for lower speed signal lines where minimal signal degradation is required. It operates over a temperature range of -65°C to 150°C.

 

The 1SMA54AT3G is housed in a 6-WDFN exposed pad package (supplier device package 6-TDFN-EP, 3x3mm), designed for surface mount assembly. The exposed pad enhances thermal dissipation during surge events. This part is RoHS3 compliant and has an MSL of 1 (unlimited). It is intended for general purpose circuit protection applications where unidirectional TVS protection is needed.
