STMicroelectronics 1-Element Bi-Directional TVS Diode 1.5 kW 2-Pin DO-214 SM15T18CAY

STMicroelectronics SM15T18CAY is a high-performance 1-element bi-directional transient voltage suppressor (TVS) diode rated at 1.5 kW peak pulse power dissipation. Housed in a compact DO-214 surface mount package with 2 pins, this diode provides robust protection against voltage spikes and transient surges, making it suitable for protecting sensitive semiconductor devices.

This TVS diode features a minimum breakdown voltage (Vbr) of 17.1 V and a maximum reverse standoff voltage (Vwm) of 15.3 V, effectively clamping voltages to a maximum of 32.5 V during transient events. It supports continuous operating temperatures from -40°C up to 150°C, ensuring operational stability in demanding industrial, automotive, and consumer electronics environments.

The device's peak pulse current (Ippm) is rated at 308 A with a test current of 1 mA, enabling it to absorb and dissipate high surge currents safely without damage. Its low leakage current of 1 μA minimizes power loss in normal operation. Compliant with automotive standard AEC-Q101, this diode is suitable for automotive electronic system voltage protection applications.

Compact dimensions (7.15 mm L × 6.25 mm W × 2.45 mm H) allow for easy integration on printed circuit boards using surface mount assembly processes. Its single diode configuration and bi-directional clamping capability provide symmetrical protection, applicable for AC and DC voltage lines.
