Product Overview
MUR3060PA combines two 15A fast-recovery paths in a common-anode TO-247AD package. Its 30A total current rating and 600V reverse blocking suit higher-voltage commutation and current-steering networks.
The 30A total device rating comprises two 15A diode paths. Evaluate each branch at its own current waveform and operating temperature when calculating conduction loss and the required cooling.
Key Features
● 600V repetitive peak reverse voltage and two 15A diode paths.
● 50ns maximum reverse-recovery time under the specified 0.5A test condition.
● 1.7V maximum forward voltage at 15A and 25°C.
● 200A non-repetitive surge current per diode for a 8.3ms pulse.

Electrical Configuration and Pinout
Two separate cathodes connect to a shared anode. With the marking face toward you and the leads pointing down, the lead functions are K1, A and K2 from left to right. The exposed metal tab is also connected to A.
Figure 1. Circuit and connection detail from the MUR3060PA datasheet, page 1. A = anode; K = cathode.
| Connection | Function |
| Left lead | K1 — first diode cathode |
| Center lead | A — common anode |
| Right lead | K2 — second diode cathode |
| Metal tab | A — electrically connected to the common anode |
Typical Applications
● Industrial inverter commutation stages.
● Motor-drive power modules.
● Higher-voltage common-anode recovery paths.
600V Common Anode Rectification in TO-247AD
Compared with a 400V TO-220AB common-anode device, MUR3060PA changes voltage class, mounting format and thermal resistance. Check the 1.7V maximum forward voltage at 15A and 25°C when evaluating the resulting conduction loss.
Design Notes
Evaluate each diode at its own current waveform and duty cycle. The 30A total device rating does not mean one junction can carry 30A. Check reverse-voltage peaks, including switching transients, against the 600V rating.
The metal tab carries the common anode potential. If the heatsink must remain at a different potential, use an appropriate insulating mounting interface and include its thermal resistance.
The 50ns recovery limit uses the low-current test condition in the parameter table. Evaluate recovery at the application current and temperature. The 200A surge specification is non-repetitive and must not be used as a repetitive overload rating.
FAQ
MUR3060PA raises VRRM to 600 V and uses TO-247AD with a lower specified Rth(j-c). Both are common-anode devices, but they are not mechanical substitutes.
Higher-voltage structures commonly involve a conduction trade-off. Use the device’s own 1.7 V maximum and 1.16 V hot typical points in the loss model.
No isolation is stated; the tab participates in the common-anode connection. Use a rated insulating interface if the heatsink must be at another potential.
Not by itself. Combine recovery curves, current slope, reverse voltage, device temperature, and circuit inductance.
