SZ1SMA13CAT3G Description

Short technical summary and product information.

The Littelfuse SZ1SMA13CAT3G is a bidirectional single-channel Zener TVS diode rated at 400W peak pulse power. It features a reverse standoff voltage of 13V, a clamping voltage of 21.5V, and a peak pulse current capability of 18.6A. Designed for automotive applications, this TVS diode provides robust protection against voltage transients on signal and power lines.

 

With a surface-mount DO-214AC (SMA) package, the device supports an operating junction temperature range of -65°C to 150°C and has a typical capacitance of 455 pF at 1 MHz. It does not offer power line protection. The Zener technology ensures precise voltage clamping for reliable circuit protection.

 

Engineered to meet the demands of automotive electronics, the SZ1SMA13CAT3G is suitable for use in harsh environments requiring high reliability and transient withstand capability.
