Bipolar Type

SEMITEC Voltage Regulating Diode (VRD) is a transient voltage suppressor device that is designed to absorb voltage surges and spikes that during power initiation. Our VRD features uniform avalanche breakdown across the junction, enabling very fast response to surge voltage. Furthermore, its control voltage is almost independent from the current which makes it a highly reliable, high performance devices. SEMITEC’S VRD series is fully compliant with RoHS DIRECTIVE2011/65/EU.
