STMICROELECTRONICS SMAJ12ATR Surge Protection Diode

The SMAJ12ATR is a unidirectional Transil diode designed to protect sensitive electronic equipment from electrostatic discharges and electrical surges caused by lightning or switching transients. It features high peak pulse power dissipation of 400 W (10/1000 us) and stands off voltages from 5 V to 188 V, complying with IEC 61000-4-2, MIL STD 883, and UL standards. Packaged in a JEDEC DO-214AC package with low leakage current and high junction temperature stability, it is ideal for high-end equipment, SMPS, and surge protection circuits for reliable performance over time.
