SMDJ18A-HR Description

Short technical summary and product information.

The SMDJ18A-HR is a high-reliability unidirectional TVS diode from Littelfuse, part of the SMDJ-HR series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. This device offers a peak pulse power dissipation of 3000W (10/1000µs waveform) and features a reverse standoff voltage of 18V with a clamping voltage of 29.2V at 102.7A peak pulse current.

 

Key electrical characteristics include a maximum forward surge current of 300A (8.3ms half sine wave) and a maximum forward voltage of 3.5V at 100A. The device is AEC-Q101 qualified for automotive applications and features a fast response time of less than 1.0ps from 0V to minimum breakdown voltage. Typical reverse leakage current is ≤2µA for reverse voltages above 10V.

 

The SMDJ18A-HR is housed in a surface-mount DO-214AB (SMC) package with a low profile and built-in strain relief. It is rated for operating junction temperatures from -65°C to 150°C. The device is RoHS compliant, halogen free, and meets MSL level 1 per J-STD-020. It is suitable for general-purpose transient voltage suppression in telecom, computer, industrial, and consumer electronics.
