Overview
The SMBJ30CA-TR is a Transient Voltage Suppressor (TVS) diode manufactured by STMicroelectronics. This component is designed to protect sensitive equipment against electrostatic discharges (ESD) and electrical overstress. It complies with standards such as IEC 61000-4-2, IEC 61000-4-4, and MIL STD 883, method 3015. The SMBJ30CA-TR is particularly suited for high-end equipment and Switch-Mode Power Supplies (SMPS) where low leakage current and high junction temperature are critical for reliability and stability.
