SMAJ18CA-TR Description

Short technical summary and product information.

The SMAJ18CA-TR is a bidirectional Zener TVS diode designed for transient voltage suppression in general purpose applications. It features a reverse standoff voltage of 18V and a clamping voltage of 39.3V, capable of handling peak pulse currents up to 59A (8/20µs waveform) with a peak pulse power rating of 400W. The device is constructed using Zener technology and provides protection for a single bidirectional channel. It is mounted using surface mount technology and is housed in a DO-214AC (SMA) package with the supplier device package designated as SMA (DO-214AC). The operating temperature range spans from -55°C to 150°C (junction temperature). The SMAJ18CA-TR is suitable for general purpose circuit protection where transient voltage suppression is required.
