STMICROELECTRONICS SM15T12A Transient Voltage Suppressor

The Transil SM15T series TVS diode safeguards sensitive electronic equipment from electrostatic discharges following IEC 61000-4-2 and MIL STD 883, method 3015. It also protects against electrical overstress in accordance with IEC 61000-4-4 and 61000-4-5, suitable for surges below 1500W (10/1000µs). These devices utilize planar technology for high reliability in high-end equipment and SMPS, combining low leakage current with high junction temperature tolerance. Available in unidirectional and bidirectional types, with breakdown voltage from 6.8 to 220V, operational temperature from -55°C to 150°C, ideal for defense, aerospace, power management, and industrial systems.
