STMicroelectronics 1-Element Uni-Directional TVS Diode Surface Mount 1.5 kW, 31.4 V Minimum Breakdown Voltage SM15T33A

STMicroelectronics SM15T33A is a high-performance 1-Element Uni-Directional Transient Voltage Suppressor (TVS) diode designed for surface mount applications. It features a peak pulse power dissipation rating of 1.5 kW, making it capable of protecting sensitive electronics against voltage transients and surges.

The device operates within a wide temperature range of -55°C to 150°C, ensuring reliable performance across harsh industrial environments. Its uni-directional diode configuration is optimized for single-direction surge suppression, suitable for applications requiring directional voltage protection.

Encapsulated in an SMC surface mount package with a compact footprint (7.15 mm length, 6.25 mm width, and 2.45 mm height), the SM15T33A facilitates efficient PCB space usage. With a minimum breakdown voltage of 31.4 V and a clamping voltage of 59 V, it provides precise transient voltage limiting to protect downstream components.

This TVS diode is ideal for use in various electronic systems including industrial controls, power supplies, telecommunication equipment, and automotive electronics where transient voltage suppression is critical. The maximum reverse stand-off voltage is 28.2 V, allowing it to remain inactive during normal voltage conditions yet respond swiftly to transient events.

Other notable features include a test current of 1 mA, a peak pulse current capability of 169 A, and minimal reverse leakage current of 1 µA ensuring low power loss. Although the device does not have specific automotive certification, it offers robust transient voltage protection for a wide range of commercial and industrial electronics.
