Product Introduction

Overview

The SMBJ30A-TR is a Transient Voltage Suppressor (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive equipment against electrostatic discharges (ESD) and electrical overstress. This device complies with international standards such as IEC 61000-4-2 and MIL STD 883, method 3015, ensuring robust protection against transient overvoltages. The SMBJ30A-TR is particularly suited for high-end equipment and Switch-Mode Power Supplies (SMPS) due to its low leakage current and high junction temperature capabilities, providing reliability and stability over time.
