P4SMA27CA TVS Diode – 400W Bidirectional Transient Suppressor (SMA Package)

Product Description:
The P4SMA27CA 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 delivers excellent surge handling capability and exceptionally fast response time, making it ideal for industrial, telecom, automotive, and consumer applications.

With a working stand-off voltage of 23.1V, breakdown voltage range of 25.7V to 28.4V, and a maximum clamping voltage of 37.5V, the P4SMA27CA ensures robust protection for a wide range of electronic circuits. Its peak pulse current of 10.7A and 400W peak pulse power rating make it suitable for high-energy transient suppression.

Engineered with glass-passivated chip junction technology, this diode offers excellent reliability and stability, meeting AEC-Q101 automotive qualification standards. Fully RoHS and halogen-free compliant, it is an ideal choice for durable and environmentally friendly circuit designs.
