Additional Details:

The P6KE440CA-E3/73 TVS diode has a stand-off voltage of 440V, meaning it does not conduct under normal operating conditions until the voltage exceeds this level. When a transient event occurs, the diode quickly clamps the voltage to a safe level, diverting the excess current away from the protected circuit. The device is available in a DO-204AC (DO-15) package for through-hole mounting. Its excellent clamping capability and fast response time make it an ideal choice for protecting sensitive electronic equipment.

This TVS diode is commonly used in telecommunications equipment, industrial control systems, and consumer electronics to protect against transient voltage surges. Vishay's commitment to quality and reliability ensures that the P6KE440CA-E3/73 provides effective and long-lasting protection for critical electronic components.
