Product details
Overview
MBR20H100CT-G1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220-3 package, rated for 100 V reverse voltage, 10 A average forward current per diode leg (20 A total), and 0.77 V max forward voltage at 10 A and +25°C. It operates up to +175°C junction temperature and is optimized for high-frequency switch-mode power supply output rectification.
For engineers reviewing the MBR20H100CT-G1 datasheet, MBR20H100CT-G1 pinout, MBR20H100CT-G1 application, or MBR20H100CT-G1 equivalent, key selection criteria include low VF at high current, low IR at elevated temperature, surge robustness (250 A IFSM), thermal resistance (2.0°C/W RθJC), and RoHS-compliant "Green" packaging with halogen/antimony-free molding compound.
Technical Context
This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a common cathode (K), enabling synchronous or interleaved rectification in center-tapped or dual-output topologies. Its guard-ring structure enhances ruggedness against transient overvoltage and thermal stress.
Designed for medium-voltage, high-frequency operation, it delivers low switching losses and minimal EMI due to absence of minority-carrier storage delay. The device sustains 10000 V/µs dv/dt and exhibits <0.0045 mA reverse leakage at +25°C and <6.0 mA at +125°C under rated DC blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode can block without breakdown; defines safe operating range in DC-DC and AC-DC secondary-side rectification. |
| IF(AV) per leg | 10 A - Continuous average forward current per anode-cathode path at TC = +162°C; supports 20 A total dual-leg output in compact TO-220 layout. |
| VF @ 10A, +25°C | 0.77 V - Low conduction loss enables >92% efficiency in 12–48 V output SMPS designs; reduces heatsink requirements vs. silicon PN rectifiers. |
| IR @ +25°C | 0.0045 mA - Ultra-low reverse leakage minimizes standby power loss and improves reliability in high-impedance bias networks. |
| RθJC | 2.0 °C/W - Junction-to-case thermal resistance for TO-220-3 package; allows direct mounting to heatsink for sustained 10 A/leg operation without derating. |
| TJ(max) | +175°C - Maximum junction temperature rating; supports operation in thermally constrained industrial and telecom power enclosures. |
| IFSM | 250 A - Non-repetitive peak surge current capability; withstands inrush and fault transients in offline PSUs and motor drive supplies. |
Pinout & Package
MBR20H100CT-G1 is housed in a TO-220-3 (2) plastic package with isolated tab (non-conductive backside), matte tin-plated copper leadframe, and UL 94V-0 molded compound. Pin assignments (front view): Pin 1 = Anode 1 (A1), Pin 2 = Cathode (K), Pin 3 = Anode 2 (A2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (A1) | Anode of first Schottky diode | Connects to input node of first rectification path; electrically isolated from A2 and K until bonded internally. |
| Pin 2 (K) | Common cathode | Shared output node for both diodes; must be routed with low-inductance trace to minimize switching noise in high-frequency converters. |
| Pin 3 (A2) | Anode of second Schottky diode | Connects to input node of second rectification path; enables dual-output or center-tapped transformer configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.77 V max @ 10 A, +25°C - Reduces conduction loss by ~40% versus comparable 100 V Si fast recovery diodes, directly improving system efficiency. |
| Guard-ring protected junction | Enhanced edge termination - Increases ruggedness against voltage transients and localized thermal runaway during line surges or short-circuit events. |
| +175°C operating junction temperature | Extended thermal margin - Enables reliable operation in sealed or high-ambient environments (e.g., industrial PLC power modules) without forced cooling. |
| Pb-free "Green" package | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - Meets IPC-1752A Class 2 reporting and EU RoHS 2 compliance without compromising mechanical or thermal performance. |
| High dv/dt immunity | 10000 V/µs - Suppresses false triggering in high-slew-rate circuits such as resonant LLC and phase-shifted full-bridge converters. |

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 | Same 100 V/10 A per leg rating but VF = 0.82 V @ 10 A, +25°C; RθJC = 2.5°C/W; no "Green" halogen-free certification. | Suitable for cost-sensitive industrial supplies where RoHS II and halogen-free compliance are not mandated. | Select when legacy qualification or distributor stock availability outweighs 50 mV VF penalty and environmental compliance requirements. |
| ON Semiconductor MBR20100CT | VF = 0.80 V @ 10 A, +25°C; IR = 0.005 mA @ +25°C; TO-220AB package with conductive tab (requires insulator); no guard ring. | Better suited for non-isolated, low-cost AC-DC adapters where tab isolation is unnecessary and surge robustness is secondary. | Prefer only if existing design uses conductive-tab TO-220AB and thermal interface permits higher RθJC; avoid in high-reliability or high-dv/dt systems. |

FAQ
Is MBR20H100CT-G1 pin-compatible with standard TO-220-3 dual-diode rectifiers?
Yes - MBR20H100CT-G1 uses standard TO-220-3 (2) mechanical outline with Pin 1 = A1, Pin 2 = K, Pin 3 = A2. It matches the pinout of industry-standard dual common-cathode Schottky rectifiers including MBR20100CT and SR20100CT, enabling drop-in replacement in existing layouts without PCB revision.
What is the maximum continuous power dissipation at TC = +100°C?
At TC = +100°C, the device supports 10 A per leg continuously. With VF ≈ 0.70 V (interpolated from datasheet curves at +100°C), total conduction loss is ~14 W (2 × 10 A × 0.70 V). Using RθJC = 2.0°C/W, junction temperature rise is 28°C - well within the +175°C limit, confirming safe operation without additional heatsinking beyond standard TO-220 mounting.
Does the "G1" suffix indicate functional differences beyond packaging?
No - the "G1" suffix denotes Diodes Incorporated's halogen- and antimony-free "Green" package variant only. Electrical specifications, thermal ratings, pinout, and internal die structure are identical to the "E1" (RoHS-compliant Pb-free) version. Both share the same DS36966 datasheet and qualify for identical applications.
Can MBR20H100CT-G1 be used in place of a single 20 A Schottky rectifier?
No - MBR20H100CT-G1 contains two independent 10 A diodes sharing a cathode; it is not a single 20 A device. Substituting it for a true 20 A single-anode Schottky (e.g., MBR30100CT) would require circuit redesign to accommodate dual-anode topology and may compromise current sharing or thermal balance in non-interleaved designs.
