Product details
Overview
MBR30H100CT-G1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 15 A average forward current per diode leg (30 A total), and 0.8 V max forward voltage at 15 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 MBR30H100CT-G1 datasheet, MBR30H100CT-G1 pinout, MBR30H100CT-G1 application, or MBR30H100CT-G1 equivalent, key selection criteria include low VF for efficiency, high surge rating (250 A IFSM), thermal resistance (2.5 °C/W RθJC), RoHS/Green compliance, and TO-220F-3 insulated package suitability for medium-voltage industrial power converters.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V/15 A diode legs sharing a single cathode terminal (Pin 2), enabling synchronous or interleaved output rectification. Its guard-ring structure enhances ruggedness against transient overvoltage stress.
Designed for high-frequency operation, it delivers low switching losses and minimal reverse recovery noise due to near-zero QRR. The device's 10,000 V/µs dv/dt rating and >8 kV HBM ESD tolerance support reliable performance in noisy power converter environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode leg; defines safe DC/peak AC voltage margin in SMPS secondary-side designs. |
| IF(AV) per leg | 15 A - Continuous average forward current per diode at TC = +162°C; supports 30 A total dual-leg output with proper heatsinking. |
| VF (max) | 0.80 V @ 15 A, +25°C - Low conduction loss directly reduces power dissipation and improves system efficiency in high-current outputs. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance for TO-220F-3 package; enables predictable thermal design when mounted on heatsink. |
| IFSM | 250 A - Non-repetitive peak surge current capability; withstands inrush and fault transients in AC-DC and DC-DC converters. |
| TJ(max) | +175°C - Maximum operating junction temperature; allows robust operation under high ambient or thermally constrained conditions. |
| IR (max) | 0.0045 mA @ +25°C - Ultra-low reverse leakage ensures minimal standby power loss in offline and adapter applications. |
Pinout & Package
MBR30H100CT-G1 uses the TO-220F-3 (full-pack insulated) package: molded plastic case with isolated mounting tab, UL 94V-0 rating, and matte tin–annealed copper leadframe. Pin 1 (A1) and Pin 3 (A2) are anode terminals; Pin 2 (K) is the common cathode.
| 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 dual-output or interleaved topologies. |
| 2 (K) | Common Cathode | Shared output node for both diodes; ties to output capacitor and load return path; requires low-inductance layout for EMI control. |
| 3 (A2) | Anode Leg 2 | Input terminal for second Schottky diode; enables independent or phase-shifted rectification without external cathode wiring. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.80 V @ 15 A, +25°C - Reduces conduction loss by ~30% vs. standard silicon rectifiers, improving 12 V/24 V SMPS efficiency. |
| Guard-ring protected junction | Enhanced edge termination - Increases ruggedness against voltage transients and mechanical stress during board assembly or field operation. |
| +175°C TJ(max) | Extended thermal operating range - Enables use in sealed enclosures or high-ambient environments without derating penalties. |
| TO-220F-3 insulation | Isolated metal tab - Eliminates need for insulating washers in heatsink mounting; simplifies thermal management and reduces BOM count. |
| RoHS/Green compliant | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - Meets global environmental regulations and supports automotive/harsh-environment qualification pathways. |

FAQ
What is the thermal resistance from junction to case (RθJC) for MBR30H100CT-G1?
The maximum thermal resistance from junction to case is 2.5 °C/W for the TO-220F-3 package. This value assumes proper mounting on a heatsink with recommended pad layout per Diodes' package outline documentation. It enables accurate junction temperature estimation under steady-state load conditions.
Is MBR30H100CT-G1 suitable for automotive applications?
MBR30H100CT-G1 is not AEC-Q101 qualified and is not recommended for new automotive designs. While it meets RoHS/Green requirements and operates up to +175°C, Diodes explicitly states that automotive-grade variants require PPAP capability and IATF 16949 manufacturing-contact Diodes directly for qualified alternatives.
How does the common-cathode configuration affect PCB layout?
The common-cathode (Pin 2) configuration simplifies output node routing by consolidating both diode returns into a single low-inductance path. This reduces loop area, lowers EMI emissions, and avoids mismatched cathode traces that could cause current imbalance between legs in high-frequency operation.
Why is MBR30H100CT-G1 marked "NOT RECOMMENDED FOR NEW DESIGN"?
Diodes has designated MBR30H100CT-G1 as not recommended for new designs due to product lifecycle status-not electrical obsolescence. No alternate part is offered, indicating planned discontinuation. Customers should evaluate next-generation Schottky rectifiers from Diodes' MBRX series or contact Aetrix for supported replacements with compatible specs and TO-220F-3 footprint.
