30KPA43A-B Description

Short technical summary and product information.

The 30KPA43A-B is a unidirectional TVS diode from the 30KPA series by Littelfuse. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. With a peak pulse power dissipation of 30kW (10/1000μs waveform) and a maximum clamping voltage of 73V, it can handle high-energy surges. The device offers a fast response time of less than 1ps and is rated for ESD protection up to 30kV (air and contact) per IEC-61000-4-2. It is housed in a P600 axial leaded package with through-hole mounting, suitable for high-reliability applications. The operating junction temperature range is -55°C to 175°C, and it is RoHS compliant, halogen free, and UL recognized (UL 497B). Typical applications include I/O interfaces, VCC bus protection, and general-purpose transient suppression in telecom, industrial, and consumer electronics.
