STMICROELECTRONICS SM6T33A Transient Voltage Suppressor

The SM6T33A Transil is a high-reliability transient voltage suppression diode designed for protecting sensitive electronic equipment against electrostatic discharges and electrical overstress. It features a uni- or bidirectional configuration with a breakdown voltage range from 6.8 V to 220 V, peak pulse power up to 600 W (10/1000 us), and high power capability at max temperature. Packaged in a JEDEC SMB outline, it meets standards such as IEC 61000-4-2, IEC 61000-4-5, UL 497B, and MIL-STD-883G. Engineered with planar technology for stability and low leakage current, suitable for high-end applications and power supply modules.
