Product details
Overview
MBR20100CTF-G1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 10 A average forward current per diode leg (20 A total), and 0.85 V max forward voltage at +25°C. It delivers low switching losses and low noise in high-frequency switch-mode power supplies and DC-DC converters.
For engineers reviewing the MBR20100CTF-G1 datasheet, MBR20100CTF-G1 pinout, MBR20100CTF-G1 application, or MBR20100CTF-G1 equivalent, key selection criteria include its dual-diode topology with common cathode, thermal resistance of 4.5 °C/W (junction-to-case), 150 °C maximum junction temperature, and RoHS-compliant green packaging - critical for compact, thermally constrained power supply designs.
Technical Context
This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a single cathode (K), enabling synchronous or interleaved rectification in center-tapped or dual-output topologies. Its guard-ring structure enhances ruggedness against transient overvoltage stress.
Designed for medium-voltage, high-frequency operation, it supports non-repetitive surge currents up to 150 A and exhibits <0.1 mA reverse leakage at +25°C, with dv/dt capability of 10,000 V/µs - essential for minimizing EMI in fast-switching converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode can block without breakdown. |
| IF(AV) per leg | 10 A - Continuous average forward current per diode at TC = +122°C, defining thermal design margin. |
| VF (max) | 0.85 V @ IF = 10 A, TC = +25°C - Directly determines conduction loss and heat generation at nominal load. |
| IR (max) | 0.1 mA @ VR = 100 V, TC = +25°C - Low leakage preserves efficiency in standby and light-load conditions. |
| RθJC | 4.5 °C/W - Junction-to-case thermal resistance for TO-220F-3 package, enabling precise heatsink sizing. |
| TJ(max) | +150 °C - Maximum allowable junction temperature, setting upper limit for thermal derating. |
| IFSM | 150 A - Non-repetitive peak surge current rating, supporting inrush and fault-current robustness. |
Pinout & Package
MBR20100CTF-G1 uses the TO-220F-3 (full-pack) insulated package with plastic body and integral heatsink tab. The case is electrically isolated from internal circuitry, allowing direct mounting to grounded heatsinks without insulation hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode 1 | Input terminal for first Schottky diode leg; connects to transformer secondary or switching node. |
| 2 (K) | Common Cathode | Shared output node for both diodes; ties to output capacitor positive rail in dual-output or center-tap designs. |
| 3 (A2) | Anode 2 | Input terminal for second Schottky diode leg; enables independent or phase-shifted rectification paths. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.85 V @ 10 A ensures ≤8.5 W conduction loss per leg at room temperature, reducing thermal load. |
| Guard-ring protected junction | Enhances reliability under repetitive voltage transients and line surges common in industrial AC-DC front-ends. |
| High TJ operation | +150 °C junction rating allows sustained operation in enclosed, high-ambient environments without derating. |
| Lead-free & halogen-free | RoHS 3 compliant and "Green" certified (<900 ppm Br/Cl, <1000 ppm Sb), meeting automotive and industrial environmental mandates. |
Applications
| AC-DC Adapter Output Stage | Server PSU Secondary Rectification |
|---|---|
Use Scenario: 12 V/24 V output stage of universal-input offline adapters powering consumer electronics. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier performing synchronous rectification across split-winding or dual-output transformer secondaries. Use Value: 0.85 V VF minimizes conduction loss at 10–20 A loads, improving efficiency by ≥1.2% versus standard silicon diodes and reducing heatsink size. |
Use Scenario: High-density 48 V input server power supplies with dual +12 V and +5 V outputs. IC Role / Device Role / Timing Role: Common-cathode dual rectifier delivering independent, low-noise DC rails from center-tapped transformer windings. Use Value: 150 A IFSM withstands cold-start inrush; TO-220F-3's insulated tab simplifies mechanical layout on shared heatsinks. |
| Industrial PLC Power Module | Telecom DC-DC Converter |
Use Scenario: 24 V auxiliary power module in programmable logic controllers operating in 70 °C ambient enclosures. IC Role / Device Role / Timing Role: Primary output rectifier handling continuous 10 A load with high thermal cycling endurance. Use Value: +150 °C TJ rating and 4.5 °C/W RθJC enable stable operation without forced air, supporting fanless industrial design. |
Use Scenario: Isolated 48 V to 3.3 V/5 V DC-DC converter in telecom line cards requiring low EMI. IC Role / Device Role / Timing Role: High-frequency rectifier in forward or flyback topology where low reverse recovery noise is mandatory. Use Value: Schottky architecture eliminates reverse recovery charge (Qrr ≈ 0), eliminating switching spikes and easing EMI filter design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH05-M3 | 50 V VRRM, same TO-220F-3 package, 0.55 V VF @ 10 A - lower voltage, significantly lower forward drop. | Suitable only for ≤50 V systems; not interchangeable in 100 V designs like telecom 48 V PoE or industrial 24 V inputs. | Select when system VR ≤ 50 V and ultra-low VF is prioritized over voltage margin. |
| ON Semiconductor MBR20100CT | Same 100 V/10 A rating and TO-220-3 (non-insulated) package; RθJC = 2.5 °C/W but requires electrical isolation hardware. | Requires mica washer or insulating pad for heatsink mounting; higher thermal performance but added BOM and assembly cost. | Choose if thermal budget is tight and mechanical isolation can be implemented reliably in production. |
Compared with VS-20CPH05-M3 and MBR20100CT, the MBR20100CTF-G1 uniquely balances 100 V blocking, TO-220F-3 insulation, and 0.85 V VF - making it optimal for space-constrained, safety-isolated, medium-voltage power supplies where thermal management and regulatory compliance are co-prioritized.

FAQ
What is the thermal resistance of MBR20100CTF-G1, and how does it impact heatsink selection?
The MBR20100CTF-G1 has a junction-to-case thermal resistance (RθJC) of 4.5 °C/W in its TO-220F-3 package. This value, combined with the maximum 150 °C junction temperature and expected power dissipation (e.g., ~8.5 W at 10 A/0.85 V), directly determines required heatsink thermal resistance to maintain safe operating temperature. For example, at 70 °C ambient and 10 W dissipation, a heatsink with ≤17.8 °C/W RθSA is needed.
Can MBR20100CTF-G1 replace a single-diode Schottky in a dual-output design?
Yes - its dual-anode/common-cathode configuration is purpose-built for dual-output or center-tapped transformer topologies. Unlike two separate diodes, it guarantees matched VF and thermal coupling between legs, improving current sharing and reducing layout parasitics. Pin 1 (A1) and Pin 3 (A2) connect to independent winding ends, while Pin 2 (K) serves as the unified output node.
Is MBR20100CTF-G1 qualified for automotive applications?
No - the MBR20100CTF-G1 is not AEC-Q101 qualified. Diodes Incorporated explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing - none of which apply to this part. It is intended for industrial, computing, and consumer power applications where AEC qualification is not mandated.
How does the TO-220F-3 package differ electrically from TO-220-3 (2)?
The TO-220F-3 package features an electrically insulated metal tab, allowing direct mounting to a grounded heatsink without additional isolation hardware. In contrast, the TO-220-3 (2) variant has an electrically connected tab, requiring mica washers or thermal pads for isolation. This makes TO-220F-3 ideal for safety-critical or compact layouts where creepage/clearance must be maintained without extra components.
