5KP33A 5000 W Unidirectional TVS Diode – 33 V Standoff

5KP33A is a unidirectional tvs diode for transient-voltage suppression, with a 33 V reverse standoff voltage and 5,000 W peak pulse capability on a 10/1000 µs waveform. Its axial through-hole package suits compatible PCB assemblies and repair work.

Key specifications

Typical applications

• High-energy transient suppression on compatible DC rails
• Power-input protection in industrial electronics
• Repair and replacement where the circuit specifies 5KP33A

Selection notes

Choose the standoff voltage above the circuit's highest normal operating voltage and verify the clamping voltage, pulse energy and thermal derating against the protected circuit. A TVS suppresses short transients; it does not regulate a continuous overvoltage.

Frequently asked questions

What is 5KP33A used for?

5KP33A limits short voltage transients in circuits whose normal voltage, clamping limit and pulse requirements match its datasheet.

Is 5KP33A interchangeable with 5KP33CA?

They share a voltage family but differ in directionality. 5KP33A is unidirectional; 5KP33CA is bidirectional. Use the type required by the original circuit.

Is 5,000 W a continuous power rating?

No. It is a peak pulse rating for the specified transient waveform. Continuous dissipation is much lower and depends on mounting and thermal conditions.

Does 5KP33A have polarity?

Yes. The band marks the cathode. In a typical positive DC shunt-protection arrangement, the cathode connects to the positive rail and the anode to return.
