1.5SMC39AT3 Description

Short technical summary and product information.

The 1.5SMC39AT3 is a 1500W peak power unidirectional Zener transient voltage suppressor diode manufactured by ON Semiconductor. It is designed to protect sensitive electronic circuits from high voltage transients.

 

Key electrical specifications include a reverse standoff voltage of 33.3V, a clamping voltage of 53.9V at a peak pulse current of 28A, and a peak pulse power rating of 1500W. The device offers a fast response time of less than 1 ns and an ESD rating of Class 3 (>16 kV HBM). It is not intended for power line protection.

 

The device is housed in a DO-214AB (SMC) surface-mount package with L-bend leads, suitable for automated assembly. It operates over a temperature range of -65°C to 150°C. The part is supplied in tape and reel packaging with a standard quantity of 2500 units.

 

Typical applications include general purpose transient protection in communication systems, automotive electronics, industrial controls, and consumer equipment. The device is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified.
