SMBJ24A-TR

SMBJ24A-TR Description

The SMBJ24A-TR from STMicroelectronics is a unidirectional Zener-type TVS (Transient Voltage Suppression) diode designed for robust overvoltage protection in electronic circuits. Packaged in a surface-mount SMB (DO-214AA) form factor, it offers a 24V reverse standoff voltage (V_RWM) with a minimum breakdown voltage (V_BR) of 26.7V and a maximum clamping voltage (V_C) of 38.9V at 16A peak pulse current (I_PP). This diode is part of the TRANSIL™ series, renowned for high reliability in transient suppression applications. With a peak pulse power dissipation of 600W (10/1000µs waveform), it provides superior protection against ESD, lightning surges, and inductive load switching transients. Compliant with ROHS3 and REACH standards, it is ideal for general-purpose protection in industrial, automotive, and consumer electronics.
