Product Overview
MBR60150PT integrates two 30A Schottky diode paths around a common cathode in TO-247AD. It provides a 60A total device rating and 150V reverse blocking for high-current secondary-side rectification.
The 60A total device rating comprises two 30A diode paths. Evaluate each branch at its own current waveform and operating temperature when calculating conduction loss and the required cooling.
Key Features
● 150V repetitive peak reverse voltage and two 30A diode paths.
● Common-cathode TO-247AD package for two rectifier branches.
● 0.95V maximum forward voltage at 30A and 25°C.
● 300A non-repetitive surge current per diode for a 8.3ms pulse.

Current capability depends on case temperature and cooling. Use the datasheet derating curve when determining operating current.
Electrical Configuration and Pinout
Two separate anodes connect to a shared cathode. With the marking face toward you and the leads pointing down, the lead functions are A1, K and A2 from left to right. The exposed metal tab is also connected to K.
Figure 1. Circuit and connection detail from the MBR60150PT datasheet, page 1. A = anode; K = cathode.
| Connection | Function |
| Left lead | A1 — first diode anode |
| Center lead | K — common cathode |
| Right lead | A2 — second diode anode |
| Metal tab | K — electrically connected to the common cathode |
Typical Applications
● High-current SMPS secondary outputs.
● Industrial DC output modules.
● Common-cathode charger secondary rectifiers.
150V Schottky Rectification for High Current Outputs
The 0.95V maximum forward voltage at 30A and 25°C provides a defined conduction-loss limit at room temperature. Account for reverse-biased loss at elevated temperature as well as forward conduction when choosing the cooling system.
Design Notes
Evaluate each diode at its own current waveform and duty cycle. The 60A total device rating does not mean one junction can carry 60A. Check reverse-voltage peaks, including switching transients, against the 150V rating.
The metal tab carries the common cathode potential. If the heatsink must remain at a different potential, use an appropriate insulating mounting interface and include its thermal resistance.
Reverse leakage can contribute significant heat at elevated temperature. Include the 10mA maximum leakage at 150V and 125°C in the reverse-biased loss assessment. The surge limit is a non-repetitive pulse rating.
FAQ
Use it when the worst-case reverse voltage, including ringing and derating, fits within 150 V and the lower-voltage selection meets the loss target.
No. Reverse recovery is small compared with many PN diodes, but capacitance, leakage, wiring inductance, and switching transitions still dissipate energy.
The datasheet allows up to 10 mA at VRRM. That current can add standby loss and thermal feedback in hot equipment.
Only after a current-sharing and thermal analysis. The datasheet’s 60 A device rating does not automatically guarantee equal sharing in every external connection.
