The SMBJ40A-E3/52 is a 600W surface-mount transient voltage suppressor (TVS) diode from Vishay General Semiconductor, part of the SMBJ series. It is designed to protect sensitive electronics from voltage transients induced by inductive load switching and lightning.
This unidirectional device features a reverse standoff voltage of 40V, a minimum breakdown voltage of 44.4V at 1mA, and a maximum clamping voltage of 64.5V at a peak pulse current of 9.3A (10/1000µs waveform). It offers a peak pulse power dissipation of 600W and a steady-state power dissipation of 5.0W. The diode has a very fast response time and low incremental surge resistance.
The SMBJ40A-E3/52 is housed in a DO-214AA (SMB) package with matte tin plated leads, suitable for automated placement. It operates over a junction temperature range of -55°C to 150°C and meets MSL level 1 per J-STD-020. The E3 suffix indicates RoHS-compliant and lead-free construction.
