CRXSP20D120G3
1200 V / 20 A CR Micro SiC JBS diode, 1.4 V VF, TO-263-7 for PFC, solar and high-frequency rectification.
The CRXSP20D120G3 is a 1200 V / 20 A CR Micro silicon carbide junction barrier Schottky (JBS) diode in the surface-mount TO-263-7 package, with a typical forward voltage of 1.4 V and a surge current capability of 140 A. The JBS structure combines a Schottky barrier with a junction to deliver a low forward voltage and enhanced surge capability, and because a SiC diode stores essentially no charge, it has no reverse-recovery loss and no recovery noise, which makes it ideal for the freewheeling, rectification and power-factor-correction paths of high-frequency converters such as on-board chargers, solar inverters, SMPS and motor drives. The surface-mount package suits a compact, high-frequency board, and the positive temperature coefficient of forward voltage allows paralleling for higher current without thermal runaway. The device stands up to the inrush that occurs at power-up, when a large capacitor charges through the rectifier. Every device is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. BeiLuo holds this diode in stock and our FAE team supports diode selection, paralleling and thermal design.
FAE Professional Review
The CRXSP20D120G3 is the SiC diode we pair with 1200 V switching stages when EMI and recovery loss matter. The JBS structure gives a low forward voltage with strong surge capability, and the zero reverse recovery keeps the freewheeling path quiet. The surface-mount package suits a compact high-frequency board.

Frequently Asked Questions
What projects suit the CRXSP20D120G3?
It fits high-frequency rectification, freewheeling and power-factor correction in converters that run from a 1200 V class bus, such as on-board chargers, solar inverters and SMPS. The surface-mount package suits a compact board.
For higher current, the CRXU60D120G3 carries 60 A in a through-hole package.
Why replace a silicon fast-recovery diode?
A SiC diode has no reverse-recovery charge, so it removes the recovery loss and the switching noise of a silicon fast-recovery diode. In hard-switched PFC and freewheeling stages that cuts loss and EMI at the same time.
The JBS structure also gives strong surge capability.
Is the diode genuine and in stock?
