SA12AG Description

Short technical summary and product information.

The SA12AG is a unidirectional Zener TVS diode from On Semiconductor designed for general-purpose overvoltage protection. It features a reverse standoff voltage of 12 V and a clamping voltage of 19.9 V, ensuring sensitive downstream components are protected from voltage transients.

 

With a peak pulse power rating of 500 W and a peak pulse current of 25.1 A, this diode can handle significant surge events. The device is mounted using through-hole technology and comes in a DO-204AC (DO-15) axial leaded package, making it suitable for traditional PCB assembly processes.

 

The SA12AG operates over a junction temperature range of -55°C to 150°C, providing reliable performance in harsh environments. It is not intended for power line protection and is best suited for general-purpose circuit protection applications where a single unidirectional channel is required.
