P4SMA30CA TVS Diode – 400W Bidirectional Transient Suppressor (SMA Package)

Product Description:
The P4SMA30CA TVS Diode is a high-performance bidirectional Transient Voltage Suppressor designed to protect sensitive electronic circuits from damaging voltage spikes caused by ESD, lightning surges, inductive load switching, and other transient events. Packaged in a compact DO-214AC (SMA) surface-mount package, this diode provides excellent surge handling capability and fast response time, making it ideal for demanding industrial and automotive applications.

With a working stand-off voltage of 25.6V, breakdown voltage range of 28.5V–31.5V, and a maximum clamping voltage of 41.4V, the P4SMA30CA ensures reliable protection for power lines, communication interfaces, and sensitive ICs. Its peak pulse power rating of 400W and peak pulse current of 9.7A enable robust absorption of transient surges, delivering long-term stability and high-performance circuit protection.

This device meets AEC-Q101 automotive standards, features glass-passivated chip junction technology, and is fully RoHS and halogen-free compliant, ensuring durability and environmental safety.
