Product details
Overview
MBRF2045HC0G from Taiwan Semiconductor is a 20A, 45V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.75V max forward voltage at 20A/25°C, 150A surge capability, and guard ring over-voltage protection for automotive-grade power conversion.
For engineers reviewing the MBRF2045HC0G datasheet, MBRF2045HC0G pinout, MBRF2045HC0G application, or MBRF2045HC0G equivalent, this device supports high-efficiency DC/DC converters, SMPS secondary-side rectification, and automotive adapter designs where low conduction loss and thermal robustness are critical.
Technical Context
This single-die Schottky rectifier operates with junction temperature range –55°C to +150°C and exhibits 3°C/W junction-to-case thermal resistance. Its 10,000 V/µs dv/dt rating ensures stability under fast-switching conditions typical in high-frequency power supplies.
The device delivers 40A peak repetitive forward current (square wave, 20kHz) and maintains ≤200 µA reverse leakage at 45V/25°C, enabling reliable operation in thermally constrained environments without forced cooling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR2045CT | TO-220AB package, dual common-cathode configuration; 0.79V VF max at 20A | Requires dual-output or center-tap transformer layout; not single-anode/cathode like MBRF2045HC0G | Select when dual-channel rectification or existing TO-220AB footprint reuse is required |

FAQ
What is the maximum junction temperature rating for MBRF2045HC0G?
The MBRF2045HC0G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows the MBRF2045HC0G to operate reliably in under-hood automotive environments and high-ambient industrial settings without thermal derating below full 20A current capacity.
Is MBRF2045HC0G pin-compatible with standard TO-220AC rectifiers?
No-MBRF2045HC0G uses the ITO-220AC package, which features insulated tab isolation between the cathode and mounting surface. Unlike standard TO-220AC devices, the ITO-220AC requires dielectric interface material or insulating hardware when mounted to grounded heatsinks. This distinction must be accounted for in PCB layout and thermal design for MBRF2045HC0G.
Does MBRF2045HC0G meet halogen-free and RoHS requirements?
Yes-the MBRF2045HC0G is both RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. The "C0G" suffix explicitly denotes green compound and halogen-free construction, making the MBRF2045HC0G suitable for environmentally regulated electronics manufacturing.
What is the forward voltage specification for MBRF2045HC0G at elevated temperature?
At 20A and TJ = 125°C, the MBRF2045HC0G exhibits a typical forward voltage of 0.65V, per the Electrical Specifications table. This lower VF at high temperature reflects the negative temperature coefficient of Schottky diodes and contributes to improved thermal stability in sustained high-load operation of the MBRF2045HC0G.
How is the "H" in MBRF2045HC0G interpreted in the ordering code?
The "H" in MBRF2045HC0G indicates AEC-Q101 qualification, as defined in the Ordering Information section of the Taiwan Semiconductor datasheet. This designation confirms that the MBRF2045HC0G has undergone stress testing for automotive reliability-including temperature cycling, humidity bias, and ESD-making it suitable for safety-critical vehicle subsystems.
