MBR3045CT Common-Cathode Schottky Diode Array 45V / 15A TO-220-3
Upgrade your electronic circuit with the MBR3045CT Schottky Diode Array. Designed for rectification applications, this diode array provides reliable and efficient performance. The common cathode configuration offers convenience and versatility in circuit design — two diodes sharing a single output node, ideal for full-wave rectification and synchronous rectifier replacements.
Built around Schottky technology for fast recovery time of less than 500ns and a forward voltage (Vf) of 700mV at maximum forward current (If) of 15A. The combination of fast switching speed and low voltage drop makes it ideal for high-frequency applications and power-efficient designs — significant efficiency gain vs standard silicon rectifiers in low-voltage / high-current paths.
Typical Use in Mining Repair
- PSU secondary-side rectification — replacing failed Schottky in PSU output stages.
- Hashboard buck-converter rectifier — common cathode useful for split-rail rectification.
- Synchronous rectifier failure recovery — drop-in replacement for similar TO-220-3 Schottky.
- General low-Vf rectification — power-efficient designs needing 45V / 15A.

FAQ — MBR3045CT Schottky Diode Array
Q: Common cathode vs common anode — which to choose?
A: Match the original circuit topology. Common cathode (this part) has both diodes sharing the cathode terminal — typical in full-wave rectification or synchronous rectifier paths. Common anode shares the anode — used in different rectification topologies. Don't swap — circuit polarity matters.
Q: Why Schottky vs standard silicon diode?
A: Schottky has lower Vf (0.7V vs 1.0V silicon) and faster recovery. In high-current low-voltage paths (typical buck converter outputs), the lower Vf saves significant power. For mining PSU secondary rectification at 12V output / 30A+, Schottky is the standard choice.
Q: How do I diagnose a failed MBR3045CT?
A: Failed Schottky typically shows short (both diodes show ~0Ω across) or open (no conduction in forward direction). Visual inspection for burn marks / cracked TO-220 package confirms catastrophic failure. Excessive heat at moderate load indicates degradation.
Q: Bulk pricing for PSU repair shops?
