30KPA33A Description

Short technical summary and product information.

The 30KPA33A is a unidirectional Zener TVS diode manufactured by Littelfuse Inc. It is designed to protect sensitive electronic circuits from voltage transients and surges. The device features a reverse standoff voltage of 33 V and a clamping voltage of 58.5 V, with a peak pulse current rating of 517.9 A. It can handle a peak pulse power of 30000 W (30 kW), making it suitable for high-energy transient suppression.

 

This TVS diode is housed in a P600 axial leaded package and is intended for through-hole mounting. It operates over a wide temperature range of -55°C to 175°C, ensuring reliability in harsh environments. The part is classified as a general-purpose application device and does not include power line protection.

 

Engineers should note that the breakdown voltage and leakage current specifications are not provided in the available data. The device is unidirectional with a single channel, making it ideal for DC line protection where polarity is known.
