SMAJ40A-E3/61 Description

Short technical summary and product information.

The SMAJ40A-E3/61 is a surface-mount transient voltage suppressor (TVS) diode from Vishay General Semiconductor, part of the SMAJ series. It offers a reverse standoff voltage of 40 V and a peak pulse power rating of 400 W (10/1000 µs waveform). The device features a clamping voltage of 64.5 V at a peak pulse current of 6.2 A, providing effective protection against voltage transients.

 

This unidirectional TVS diode uses a Zener technology with a glass passivated chip junction for reliability. It is designed for general-purpose applications such as protecting sensitive electronics from inductive load switching and lightning-induced transients.

 

The device is housed in a standard DO-214AC (SMA) package with matte tin plated terminals, suitable for automated surface mount assembly. It operates over a junction temperature range of -55°C to 150°C and meets MSL level 1 requirements.
