The SMBJ18D-M3/H is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay, designed to protect sensitive electronics from voltage transients. It offers a reverse standoff voltage of 18V and a maximum clamping voltage of 28.8V at a peak pulse current of 20.8A (10/1000µs waveform). The device is rated for 600W peak pulse power, ensuring robust protection against inductive load switching and lightning-induced surges.
This TVS diode features very fast response time and low incremental surge resistance, making it suitable for use in consumer, computer, industrial, and telecommunication equipment. It is ideal for protecting ICs, MOSFETs, and signal lines of sensor units.
The component is housed in a surface-mount DO-214AA (SMB) package with matte tin plated leads, compliant with RoHS3 and halogen-free. It operates over a junction temperature range of -55°C to 150°C and meets MSL level 1 per J-STD-020.
