SM15T220A Description

Short technical summary and product information.

The SM15T220A is a unidirectional Zener TVS diode from STMicroelectronics designed for general purpose transient voltage suppression. It offers a reverse standoff voltage of 188V and a maximum clamping voltage of 388V at 26A peak pulse current (8/20µs waveform). The device can handle 1500W of peak pulse power, making it suitable for protecting sensitive electronics from voltage spikes. This TVS diode is surface mounted in a DO-214AB (SMC) package and operates over a temperature range of -55°C to 150°C. It is RoHS3 compliant, MSL 1, and REACH unaffected. The unidirectional configuration provides protection for a single line or channel in applications such as power supplies, telecom equipment, and industrial control systems.
