1SMB15AT3G Description

Short technical summary and product information.

The ON Semiconductor 1SMB15AT3G is a Zener-type unidirectional TVS diode designed for general purpose circuit protection. With a reverse standoff voltage (VRWM) of 15V and a maximum clamping voltage of 24.4V, it safely clamps transient overvoltages. The device can handle a peak pulse current of 24A (10/1000µs waveform) and offers 600W peak pulse power dissipation.

 

This TVS diode features a single unidirectional channel and has a capacitance of 1020pF at 1MHz. It is housed in a surface mount DO-214AA (SMB) package with SMD gull wing termination, suitable for automated assembly. The operating junction temperature range spans -65°C to 150°C.

 

The 1SMB15AT3G is used in low-voltage protection applications where fast response and reliable clamping are required. Its compact SMB package makes it ideal for space-constrained PCB layouts in consumer, industrial, and communication equipment.
