SMBJ18AHE3/52 Description

Short technical summary and product information.

The SMBJ18AHE3/52 is a surface-mount TRANSZORB transient voltage suppressor from Vishay's SMBJ series. It features a Zener diode structure with a reverse standoff voltage of 18 V, a maximum clamping voltage of 29.2 V at 20.5 A peak pulse current, and a peak pulse power rating of 600 W for a 10/1000 μs waveform. The device is unidirectional with 1 channel.

 

Designed for automated placement, the SMBJ18AHE3/52 comes in a DO-214AA (SMB) case with matte tin plated terminals, suitable for surface-mount assembly. It offers very fast response time and low incremental surge resistance for protecting sensitive electronics against voltage transients. The junction temperature range is -55°C to +150°C.

 

This part is AEC-Q101 qualified for automotive applications, making it suitable for use in automotive electronics. It is RoHS3 compliant and meets MSL level 1 per J-STD-020.
