Product details
Overview
MBR20H100CTF-G1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 20 A total average forward current (10 A per diode leg), and 0.77 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency power converters such as AC/DC adapters and server PSUs.
For engineers reviewing the MBR20H100CTF-G1 datasheet, MBR20H100CTF-G1 pinout, MBR20H100CTF-G1 application, or MBR20H100CTF-G1 equivalent, key selection criteria include junction temperature rating (+175°C), thermal resistance (2.5°C/W J-C), surge current capability (250 A), and RoHS-compliant "Green" packaging with halogen/antimony-free molding compound.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V, 10 A diode legs sharing a single cathode terminal. Its guard-ring structure enhances ruggedness against transient overvoltage stress, while the low VF and fast recovery enable high-efficiency operation in 100–500 kHz SMPS topologies.
The device operates up to +175°C junction temperature and supports dv/dt of 10,000 V/µs. With IR ≤ 4.5 µA at +25°C and ≤ 6 mA at +125°C, it maintains low leakage under elevated thermal load-critical for hold-up capacitor charging and synchronous rectification auxiliary paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode leg withstands without breakdown; enables use in 48 V–60 V output rails with safety margin. |
| IF(AV) per leg | 10 A - Average forward current per diode at TC = +162°C; supports 20 A total dual-leg output in compact TO-220F-3 footprint. |
| VF (max) | 0.77 V @ 10 A, +25°C - Low conduction loss reduces heat generation and improves efficiency in high-current secondary-side rectification. |
| IFSURGE | 250 A - Non-repetitive peak surge current capability; handles cold-start inrush and transient overload without failure. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance for TO-220F-3 package; allows direct heatsink mounting for reliable thermal management at full load. |
| TJ(max) | +175°C - Maximum operating junction temperature; supports extended lifetime in thermally constrained industrial and telecom power modules. |
| IR (max) | 0.0045 mA @ +25°C - Ultra-low reverse leakage ensures minimal standby power loss in energy-sensitive applications like EPS and PoE PSE. |
Pinout & Package
Package: TO-220F-3 (isolated tab), 3-terminal plastic case with insulated metal tab for safe high-voltage mounting. Dimensions: 14.7 × 10.3 × 4.5 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode Leg 1 | Input terminal for first Schottky diode; connects to transformer secondary or switching node in center-tapped or dual-output configurations. |
| 2 (K) | Common Cathode | Shared output node for both diodes; ties directly to output capacitor positive rail and serves as reference for synchronous control feedback. |
| 3 (A2) | Anode Leg 2 | Input terminal for second Schottky diode; enables dual-output or interleaved rectification without external parallel diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.77 V @ 10 A, +25°C - Reduces conduction loss by >30% vs. standard silicon rectifiers, lowering thermal design burden. |
| Guard-ring protection | Integrated edge termination - Prevents premature avalanche breakdown under voltage transients, improving reliability in unregulated input stages. |
| High TJ rating | +175°C operating junction - Enables derating headroom for continuous 20 A operation in ambient temperatures up to +85°C with proper heatsinking. |
| Green package | Halogen- and antimony-free, RoHS-compliant molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - Meets IPC-1752A environmental compliance requirements. |
Applications
| Server Power Supply Rectification | Industrial AC/DC Adapter Output |
|---|---|
Use Scenario: Secondary-side rectification in 12 V/24 V/48 V output rails of 80 PLUS Titanium PSUs.

Use Value: 0.77 V VF minimizes conduction loss at 10–20 A loads, enabling >95% efficiency at full load and reducing heatsink size by 35%. |
Use Scenario: Output rectification in DIN-rail mounted 24 V/10 A industrial power supplies for PLC I/O modules. IC Role / Device Role / Timing Role: High-reliability dual-anode rectifier handling wide ambient temperature swings (−40°C to +70°C) and line surges.

IC Role / Device Role / Timing Role: Fast-switching Schottky pair delivering low-noise, low-RFI rectified output for sensitive RF subsystems. Use Value: 10,000 V/µs dv/dt rating and low junction capacitance suppress EMI generation, easing EMC filter design and certification. |
Use Scenario: Constant-current output rectification in 36–48 V LED drivers for streetlight and high-bay luminaires. IC Role / Device Role / Timing Role: Dual-anode rectifier supporting split-string or redundant LED array configurations with shared cathode return path.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR20100CT | TO-220-3 (non-isolated tab); RθJC = 2.0°C/W; VF = 0.82 V @ 10 A, +25°C | Requires insulating washer for high-voltage mounting; higher VF increases thermal load in space-constrained designs | Select when mechanical isolation is not required and lower-cost non-Green packaging is acceptable |
| ON Semiconductor MBR20100CT | TO-220-3; no "Green" compliance; IR = 0.01 mA @ +25°C; TJ = +150°C | Lacks halogen-free certification and reduced thermal margin limits use in extended-temperature industrial environments | Select only for cost-sensitive consumer-grade adapters where RoHS/Green compliance is not mandated |
Compared with VS-MBR20100CT and MBR20100CT, MBR20H100CTF-G1 offers superior thermal performance in insulated-mount applications, lower leakage for standby-sensitive systems, and full environmental compliance-making it optimal for telecom, server, and industrial power where reliability and regulatory alignment are critical.

FAQ
Is MBR20H100CTF-G1 pin-compatible with MBR20H100CT-E1?
Yes-both share identical TO-220F-3 package and pinout (A1-K-A2). The G1 suffix denotes halogen/antimony-free "Green" packaging, while E1 indicates RoHS compliance only. Electrical specs and thermal performance are identical; G1 adds environmental compliance without functional trade-offs.
What is the maximum recommended case temperature for continuous 20 A operation?
At 20 A total (10 A per leg), the maximum sustainable case temperature is +162°C per datasheet IF(AV) rating. With RθJC = 2.5°C/W, this requires ≤ 43°C temperature rise above ambient-achievable using ≥ 15 cm² copper pour or small heatsink in forced-air environments.
Does MBR20H100CTF-G1 require a heatsink in 12 V/15 A applications?
Yes-a heatsink is strongly recommended. At 15 A total (7.5 A per leg), power dissipation is ~5.8 W (7.5 A × 0.77 V). With RθJA ≈ 40°C/W (mounted on 2 oz copper), junction temperature would exceed +150°C without additional thermal path; a 10°C/W heatsink keeps TJ < +125°C.
Can MBR20H100CTF-G1 be used in place of a single 20 A Schottky diode?
No-it is a dual 10 A common-cathode device, not a single 20 A diode. Using it as a single-diode replacement risks overstress: each anode is rated for 10 A average, so connecting both anodes together violates internal current-sharing assumptions and may cause thermal runaway.
