STMICROELECTRONICS SM6T30A Electromagnetic Surge Protector

The SM6T30A is a unidirectional Transil™ ESD protection device designed to safeguard sensitive electronic equipment from electrostatic discharges and electrical overstress. It complies with standards such as IEC 61000-4-2, MIL STD 883 method 3015, and IEC 61000-4-4 and 5. This device is suitable for protecting circuits against surges below 600W (10/1000 µs) and features planar technology, making it ideal for high-end equipment and switch-mode power supplies (SMPS) requiring low leakage current and high junction temperature for enhanced reliability and stability. The device offers a breakdown voltage range of 6.8V to 220V, low leakage current (0.2 µA at 25°C and 1 µA at 85°C), high power capability (515W at Tj max for 10/1000 µs surges), and an operating junction temperature range of -55°C to 150°C.
