STMicroelectronics 1-Element Bi-Directional TVS Diode 1.5 kW Peak Pulse Power 2-Pin DO-214 SM15T33CAY

STMicroelectronics SM15T33CAY is a 1-element bi-directional Transient Voltage Suppressor (TVS) diode featuring a peak pulse power dissipation capacity of 1.5 kW. This device is packaged in a compact DO-214 surface mount package with 2 pins, designed for efficient protection of electronic circuits against voltage spikes caused by transient events.

The diode configuration is single and bi-directional, allowing it to clamp voltage surges symmetrically in both polarities. It is engineered to handle a maximum peak pulse current of 169 A and has a minimum breakdown voltage of 31.4 V, ensuring effective suppression at voltages above the rated levels. The clamping voltage is rated at 59 V, which is the voltage level the diode limits transient voltages to, protecting sensitive components downstream.

This TVS diode supports a wide operating temperature range from -40°C to 150°C, catering well to automotive and industrial environments where temperature extremes are common. Its small footprint of 7.15 mm in length, 6.25 mm in width, and 2.45 mm in height facilitates high-density PCB layouts while maintaining strong surge protection performance.

The device complies with the AEC-Q101 automotive standard, assuring robustness and reliability for automotive system designs. The extremely low maximum reverse leakage current of 1 μA ensures minimal leakage during normal operation, contributing to energy efficiency.
