ITA18B1RL Description

Short technical summary and product information.

The ITA18B1RL is a bidirectional Zener TVS diode manufactured by STMicroelectronics, designed to protect sensitive electronics from voltage transients. It features a maximum reverse standoff voltage of 15V and a clamping voltage of 28V, capable of handling peak pulse currents up to 25A (8/20µs waveform) with a peak pulse power rating of 300W. The device offers a typical capacitance of 350pF at 1MHz, suitable for high-speed data line protection.

 

This TVS diode is intended for general purpose applications, providing overvoltage protection in a variety of circuits. Its 5 bidirectional channels allow multiple lines to be protected in a single package. The part is not recommended for power line protection, as indicated by its specification.

 

The ITA18B1RL is housed in a standard 8-SOIC surface-mount package (0.154" width, 3.90mm width), with a supplier device package of 8-SOIC. It is designed for easy integration into automated assembly processes and is RoHS3 compliant (unverified) and REACH unaffected. The moisture sensitivity level is rated as MSL 1 (unlimited floor life).
