BYC15-600P Ultrafast Power Diode for ASIC Power Supply SOD59 Package

BYC15-600P Ultrafast Power Diode for ASIC PSU Repair

The BYC15-600P is a 600V ultrafast single rectifier diode in SOD59 package, designed for the boost / PFC / output stages of ASIC miner power supplies. Fast switching, low leakage current and low reverse-recovery current reduce switching losses in the paired MOSFET / IGBT — boosting efficiency and lowering heat in rebuilt PSUs.

Original spec covers industrial switch-mode power supplies, air conditioner active PFC and high-frequency SMPS. In mining repair, it's a workhorse replacement for failed fast diodes downstream of the bus capacitor.

Typical Failure Modes Solved

• Open or short diode — PFC stage no longer boosts; bus capacitor stays at rectified mains.
• High reverse-recovery losses — old slow diode cooks the MOSFET stage; replace as a set.
• Output ripple out of spec — rectifier dying intermittently under load.
• Production refurbishment — bulk diode stock for ASIC PSU rebuild lines.

FAQ — BYC15-600P Diode

Q: When to replace the paired MOSFET as well?
A: If the diode failed short, the paired switching transistor probably ran with parasitic conduction and is degraded. Replace both as a set when in doubt.

Q: Substitution possible with SiC Schottky?
A: SiC Schottky (e.g. C3D10065A) has zero reverse recovery and runs cooler, but watch package footprint, surge rating and forward-voltage budget before swapping.
