SM6T56AY Description

Short technical summary and product information.

The SM6T56AY is a 600W unidirectional TVS diode from STMicroelectronics designed to protect sensitive circuits from transient voltage spikes. It features a reverse standoff voltage of 47.6V and a clamping voltage of 100V at a peak pulse current of 40A (8/20µs). The device utilizes Zener technology for fast and reliable overvoltage protection.

 

This TVS diode is housed in a DO-214AA (SMB) surface-mount package, offering a compact solution for space-constrained designs. With a single unidirectional channel, it is suitable for protecting DC rails and signal lines in automotive and industrial applications.

 

The junction operating temperature range spans -55°C to +150°C, allowing dependable performance in harsh environments. The part is classified as an automotive-grade component, making it ideal for use in vehicle electronics where robustness and reliability are critical.
