SM6T22A Description

Short technical summary and product information.

The SM6T22A is a 600W unidirectional TVS (Transient Voltage Suppression) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients. The device features a reverse standoff voltage of 18.8V and a clamping voltage of 30.6V, capable of handling a peak pulse current of 102A (8/20µs waveform). The TVS diode is based on Zener technology and provides a single protection channel.

 

This component is housed in a DO-214AA (SMB) surface-mount package, making it suitable for automated assembly and space-constrained designs. It operates over a junction temperature range of -55°C to 150°C. The mounting type is surface mount, enabling efficient heat dissipation and compact PCB layout.

 

The SM6T22A is listed as RoHS3 compliant, REACH unaffected, and has an MSL (Moisture Sensitivity Level) of 1 (unlimited). It is intended for general purpose applications where transient voltage protection is required, such as power supplies, consumer electronics, and industrial controls. Note that power line protection is not specified for this part.
