Additional Details:

The P6KE9.1A-E3/73 TVS diode has a stand-off voltage of 9.1V. During a transient event, the diode clamps the voltage to a safe level, diverting excess current away from the protected circuit. It comes in a DO-204AC (DO-15) package for through-hole mounting. Its clamping capability and fast response make it suitable for protecting sensitive electronics.

This TVS diode is used in communication systems, industrial control, and consumer electronics. Vishay's ensures the P6KE9.1A-E3/73 gives effective, lasting protection for components.
