LDP01-35AY

LDP01-35AY Description

The LDP01-35AY from STMicroelectronics is a high-performance unidirectional TVS diode designed for robust transient voltage suppression in automotive and industrial applications. Part of the TRANSIL™ series, this device offers a 30V reverse standoff voltage (Typ) and a 33.3V minimum breakdown voltage, ensuring reliable protection against voltage spikes. With a peak pulse current of 95A (10/1000µs) and a maximum clamping voltage of 45.5V, it effectively safeguards sensitive electronics from ESD, lightning surges, and inductive load switching events. Packaged in a D2PAK (TO-263) surface-mount format, it combines high power handling with compact design, making it suitable for space-constrained applications.
