Product details
Overview
MBRF2045CT from Diodes Incorporated is a dual common-cathode Schottky barrier rectifier in TO-220AB package, rated 45 V reverse voltage and 10 A average forward current per leg, with max 0.64 V forward voltage at 10 A and +25°C, used for polarity protection and recirculating diode functions in DC power supplies and motor drives.
For engineers reviewing the MBRF2045CT datasheet, MBRF2045CT pinout, MBRF2045CT application, or MBRF2045CT equivalent, key selection criteria include low VF for thermal efficiency, 180 A non-repetitive surge rating for transient robustness, TO-220AB thermal resistance (2°C/W junction-to-case), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling dual-channel rectification or parallel operation with shared heat sinking. Its guard ring die construction suppresses edge leakage and improves surge survivability under repetitive transients.
Designed for commercial and automotive applications, it operates across –55°C to +150°C junction temperature, with 0.1 mA max reverse leakage at rated 45 V and +25°C, and derates linearly above +25°C ambient per Figure 4 in DS23016 Rev 14.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in DC bus or flyback clamp circuits. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg at +25°C case temperature; determines steady-state power handling capability. |
| VF (max) | 0.64 V @ 10 A, +25°C - Peak forward voltage drop; directly impacts conduction loss and thermal design margin. |
| IFSM | 180 A - Non-repetitive peak surge current (8.3 ms half-sine); supports motor startup or capacitor charging inrush events. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance (TO-220AB); enables accurate heatsink sizing when mounted on standard 45 mm × 20 mm × 12 mm heatsink. |
| IR (max) | 0.1 mA @ 45 V, +25°C - Reverse leakage current; critical for low-power standby modes and high-impedance sensing nodes. |
Pinout & Package
Package: TO-220AB (Type C), molded plastic case with matte tin–plated copper leadframe, UL 94V-0 rated, weight ≈ 1.95 g. Mounting hole centered between pins 1 and 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first Schottky diode leg; connects to unregulated input or inductive load side. |
| Pin 2 | Cathode (common) | Shared output node for both diodes; must be routed with low-inductance, high-current trace to ground or return path. |
| Pin 3 | Anode 2 | Input terminal for second Schottky diode leg; enables dual-path rectification or redundancy without external wiring. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Reduces edge leakage and improves voltage standoff consistency across temperature and process variation. |
| Low VF Schottky architecture | 0.57–0.64 V typical VF range minimizes conduction loss in 12 V/24 V DC systems, reducing heatsink requirements. |
| AEC-Q101 qualified | Validated for automotive under-hood environments including thermal cycling, humidity bias, and mechanical shock testing. |
| Halogen- and antimony-free "Green" compound | Meets IEC 61249-2-21 with <900 ppm Br, <900 ppm Cl, <1500 ppm total halogens, and <1000 ppm antimony. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS2045CT | Same TO-220AB package, 45 V VRRM, 10 A IO, but VF = 0.62 V @ 10 A (+25°C); RθJC = 2.5°C/W. | Lower surge rating (150 A vs. 180 A); not AEC-Q101 qualified. | Preferred where cost sensitivity outweighs automotive qualification and surge margin. |
| VB2045-G | TO-220AB, 45 V, 10 A, VF = 0.65 V @ 10 A; RθJC = 2.2°C/W; RoHS-compliant but no AEC-Q101 data published. | Higher VF increases conduction loss; lacks documented automotive stress test validation. | Acceptable for commercial-grade industrial power supplies with relaxed reliability requirements. |
Compared with STPS2045CT and VB2045-G, MBRF2045CT delivers superior surge robustness (180 A), tighter thermal resistance (2°C/W), and verified AEC-Q101 compliance-making it the preferred choice for automotive and mission-critical industrial designs requiring long-term field stability.

FAQ
What is the maximum junction temperature for continuous operation?
The MBRF2045CT supports continuous operation up to +150°C junction temperature, with derating beginning at +25°C ambient per Figure 4 in DS23016 Rev 14. At +100°C case temperature, its average forward current drops to approximately 5.5 A per leg, based on linear derating slope of –0.07 A/°C above +25°C.
Can MBRF2045CT be used in parallel with another unit for higher current?
Parallel operation is not recommended due to mismatched forward voltage characteristics between units, which causes current imbalance and potential thermal runaway. For >10 A per leg, use a single higher-rated part such as MBRF3045CT or implement active current-sharing circuitry with matched thermal mounting.
Is the TO-220AB package electrically insulated?
No-the TO-220AB package has an electrically conductive metal tab (connected to Pin 2, the common cathode). Electrical isolation requires insulating hardware (e.g., shoulder washer, mica pad, or silicone thermal pad) and isolated mounting screw when attaching to a heatsink referenced to system ground or another potential.
Does MBRF2045CT support reflow soldering?
Yes-MBRF2045CT is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260°C for 30 seconds. The matte tin finish ensures reliable wetting, and moisture sensitivity level is rated Level 1, meaning floor life is unlimited under ≤30°C/60% RH conditions without dry pack requirements.
