The MUR3060PT is a dual-chip, center-tap ultra-fast recovery power rectifier diode housed in a heavy-duty TO-247 (TO-218 / TO-3P compatible) through-hole package. Engineered specifically for high-voltage, high-frequency switch-mode power conversion, the MUR3060PT features a repetitive peak reverse voltage rating of 600V, a total continuous forward current capacity of 30A (15A per diode leg), low forward voltage drop, and an ultra-fast reverse recovery time (t_rr) of 60ns. It is widely used in high-efficiency switch-mode power supplies (SMPS), solar inverters, high-power DC-DC converters, motor drive freewheeling circuits, and industrial battery charging systems.

Features

• Ultra-Fast 60ns Recovery Time: Substantially reduces diode reverse-recovery switching losses, minimizing EMI emissions and increasing converter efficiency at high frequencies.
• High 600V Reverse Blocking Voltage: Provides ample safety headroom against high-voltage ringing transients in off-line power supplies and solar inverters.
• Dual Center-Tap Configuration: Integrates two matched 15A diodes with a common cathode connection to simplify full-wave secondary rectification circuits and reduce PCB component count.
• High Operating Junction Temperature (175°C): Delivers exceptional thermal headroom, ensuring long-term reliability in high-temperature industrial environments.
• Glass Passivated High-Temperature Junction: Ensures minimal reverse leakage and robust avalanche withstand capability over prolonged operational lifespans.
• Heavy-Duty TO-247 Package: Large copper mounting tab provides direct heatsink mounting for superior thermal management under heavy continuous current loads.

Common Applications

• High-Voltage SMPS Secondary Rectification: Secondary output rectification in server power units, telecom rectifiers, and high-wattage industrial power supplies.
• Solar Inverters & UPS Systems: High-frequency secondary rectification and energy recycling stages in renewable power systems and battery backup units.
• High-Power DC-DC Converters: Catch and freewheeling diode stages in industrial buck, boost, and bridge topologies.
• Industrial Battery Chargers: Fast AC-DC rectification stages for electric vehicle (EV) charging stations and high-current industrial battery packs.
• Motor Drives & Inductive Clamping: High-speed freewheeling protection across inductive motors, large solenoids, and magnetic actuators.

Usage Tips

• Heatsink Installation: Always fasten the TO-247 package securely to an adequately sized aluminum heatsink using thermal paste. Use a silicone/mica insulation sheet and shoulder washer if the heatsink must remain electrically isolated from the center Cathode.
• Single 30A Diode Configuration: To utilize the full 30A continuous rating in a single-ended output circuit, connect Pin 1 (Anode 1) and Pin 3 (Anode 2) together in parallel on the PCB.
• RC Snubber Protection: Place a small RC snubber network across each diode leg to absorb high-frequency voltage spikes and ringing caused by transformer leakage inductance.
• PCB Trace Optimization: Keep high-current loops between the transformer secondary, the diode terminals, and the output filter capacitors short and wide to minimize parasitic inductance and EMI noise.
