Product details
Overview
MBR1045HC0G from Taiwan Semiconductor is a 10A, 45V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.70 V at 10 A, 25°C), high surge current capability (150 A), and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the MBR1045HC0G datasheet, MBR1045HC0G pinout, MBR1045HC0G application, or MBR1045HC0G equivalent, key selection criteria include its 45 V repetitive peak reverse voltage, 3 °C/W junction-to-case thermal resistance, 150 A non-repetitive surge rating, and matte tin-plated leads compliant with J-STD-002 solderability.
Technical Context
This device uses a single-die Schottky structure optimized for low conduction loss and fast recovery-no minority-carrier storage delay. Its guard ring design enhances ruggedness against transient overvoltage events, and the TO-220AC case enables direct heatsink mounting with ≤0.56 N·m torque.
The MBR1045HC0G operates across –55°C to +150°C junction temperature range and maintains <100 µA reverse leakage at 45 V and 25°C, dropping to <15 mA at 125°C-critical for thermally constrained industrial and automotive power stages.
Key Specifications

FAQ
What is the maximum junction temperature rating for MBR1045HC0G?
The MBR1045HC0G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in the datasheet show usable current drops linearly above 25°C case temperature, with zero derating up to 100°C case temp when mounted on a heatsink with RθJA ≤ 10°C/W.
Is MBR1045HC0G pin-compatible with standard TO-220AC rectifiers?
Yes, MBR1045HC0G uses the industry-standard TO-220AC outline with anode, cathode, and electrically connected tab-identical pinout and footprint to MBR1035 through MBR10200 series. The "H" suffix denotes AEC-Q101 qualification but does not alter mechanical dimensions or terminal assignment. Mounting torque must not exceed 0.56 N·m to avoid lead damage.
Does MBR1045HC0G have a guarded junction for overvoltage protection?
Yes, MBR1045HC0G incorporates a guard ring structure explicitly cited in its features list to prevent edge breakdown during transient overvoltage events. This design enhancement improves ruggedness in unregulated input conditions-such as those found in boost PFC stages or battery-fed DC/DC converters-without requiring external snubbers.
What is the reverse leakage current of MBR1045HC0G at 125°C?
At 125°C junction temperature and rated 45 V reverse voltage, the MBR1045HC0G exhibits ≤15 mA typical reverse leakage current (IR), per electrical specifications table. This value is confirmed under 30 ms pulse test conditions and remains within safe limits for most 12 V and 24 V output power stages-even during thermal soak testing.
How does the forward voltage of MBR1045HC0G compare at elevated temperature?
At 125°C junction temperature and 10 A forward current, the MBR1045HC0G delivers a typical forward voltage of 0.57 V-lower than its 25°C value of 0.70 V. This negative temperature coefficient improves thermal stability in parallel configurations and reduces conduction loss in high-ambient applications like enclosed LED drivers or motor control power supplies.
