The SM4T28CAY is a bidirectional Zener TVS diode from STMicroelectronics, designed to protect sensitive electronics from voltage transients. It features a 24V reverse standoff voltage and a maximum clamping voltage of 50V at 46A peak pulse current (8/20µs waveform). With a peak pulse power rating of 400W, this device provides robust transient protection for automotive and industrial applications.
This TVS diode is qualified for automotive applications and is housed in a compact DO-214AC (SMA) surface-mount package. It operates over a wide temperature range from -55°C to 150°C, making it suitable for harsh environments. The bidirectional configuration allows protection for circuits with both positive and negative transient voltages.
The SM4T28CAY is part of STMicroelectronics' SM4TY series, which is optimized for automotive systems requiring high reliability and compliance with AEC-Q101 standards. Its low-profile SMA package enables space-efficient designs on PCBs.
