SA12CA Description

Short technical summary and product information.

The SA12CA is a bidirectional Zener TVS diode from Littelfuse's SA series, designed to protect sensitive electronic equipment from voltage transients. It offers 500W peak pulse power dissipation at 10/1000μs waveform, with a reverse standoff voltage of 12V and maximum clamping voltage of 19.9V at 25.6A peak pulse current. The device features a fast response time typically less than 1ps and low incremental surge resistance.

 

This TVS diode is suitable for protecting I/O interfaces, VCC buses, and data lines in telecom, computer, industrial, and consumer electronic applications. It provides ESD protection per IEC 61000-4-2 (30kV air/contact) and EFT protection per IEC 61000-4-4. The glass passivated chip junction ensures reliability, and the plastic package is flammability rated V-0.

 

The SA12CA is housed in a DO-204AC (DO-15) through-hole package with axial leads, allowing for easy mounting on PCBs. It operates over a junction temperature range of -55°C to 175°C. The component is RoHS compliant, halogen free, and lead free (Pb-free E3), making it suitable for environmentally conscious designs.
