Best Alternatives to MUR860G

Package: TO-220-2onsemiDiodes - Rectifiers - SingleSeries: SWITCHMODE™Package: TubeVoltage - DC Reverse (Vr) (Max): 600 VCurrent - Average Rectified (Io): 8AVoltage - Forward (Vf) (Max) @ If: 1.5 V @ 8 A

The onsemi MUR860G is a 600V, 8A ultrafast rectifier in a TO-220AC package, ideal for switching power supplies. When seeking alternatives, focus on matching or exceeding voltage and current ratings, while ensuring the reverse recovery time (trr) and package type are compatible with your design.

AI replacement insight

Electrical risklow

Many parts match or exceed voltage/current. Key risk is slower trr or higher Vf.

Package riskmedium

While TO-220 is common, variants like insulated packages (TO-220FAC) exist and require thermal review.

Sourcing risklow

This is a common diode type with multiple manufacturers and available stock.

Can it be replaced directly?

Direct replacement for MUR860G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

MUR1560 offers a potential upgrade path with higher current and faster switching in the same package, representing the most direct and beneficial substitution.

Main risk

The main risk is selecting a part with a slower reverse recovery time (trr) or an incompatible package that alters thermal performance.
