Product details
Overview
MBR30100CTF-G1 from Diodes Incorporated is a high-voltage dual common-cathode 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 0.85 V max forward voltage at 15 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR30100CTF-G1 datasheet, MBR30100CTF-G1 pinout, MBR30100CTF-G1 application, or MBR30100CTF-G1 equivalent, key selection criteria include its dual-diode configuration with common cathode, thermal resistance of 4.5 °C/W (Junction-to-Case), 150°C maximum junction temperature, and RoHS-compliant green packaging.
Technical Context
This device integrates two independent Schottky diodes sharing a single cathode terminal, enabling synchronous or interleaved rectification in dual-rail or center-tapped topologies. Its guard-ring structure enhances ruggedness against transient overvoltage stress, and the low VF supports high-efficiency operation at 100–500 kHz switching frequencies.
The TO-220F-3 package features insulated mounting flange and 4.5 °C/W RθJC, allowing direct heatsink attachment without isolation hardware. Electrical specs are characterized across –55°C to +150°C storage and operating ranges, with ESD ratings >400 V (MM) and >8 kV (HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode withstands without breakdown; enables use in 48 V and 54 V bus systems with margin. |
| IF(AV) per leg | 15 A - Average forward current rating per diode at TC = +107°C; supports continuous 30 A total output in dual-leg parallel configuration. |
| VF (max) | 0.85 V @ 15 A, +25°C - Low conduction loss reduces power dissipation and thermal load in high-current DC/DC outputs. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Ultra-low leakage preserves efficiency in standby and light-load conditions. |
| RθJC | 4.5 °C/W - Junction-to-case thermal resistance for TO-220F-3; enables predictable heatsink sizing for 30 A operation at ≤150°C TJ. |
| TJ(max) | +150°C - Maximum junction temperature; allows reliable operation in enclosed industrial power supplies with limited airflow. |
| dv/dt | 10,000 V/μs - High voltage slew rate immunity prevents false turn-on during fast-switching transients in resonant converters. |
Pinout & Package
MBR30100CTF-G1 uses the TO-220F-3 package: insulated plastic case with metal tab (cathode), 3-terminal through-hole outline, and matte tin-plated copper leadframe. Mounting flange is electrically isolated from terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode Leg 1 | Connects to positive side of first transformer secondary or input rail; carries up to 15 A continuous forward current. |
| 2 (K) | Common Cathode | Shared output node for both diodes; must be routed with low-inductance path to bulk capacitor and ground plane. |
| 3 (A2) | Anode of Diode Leg 2 | Connects to second transformer secondary or auxiliary rail; enables dual-output or full-wave center-tapped rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF (0.85 V @ 15 A) | Reduces conduction loss by ~30% vs. standard silicon rectifiers, directly improving 12 V/24 V SMPS efficiency above 75% load. |
| Guard-ring protected junction | Enables stable operation under repetitive line surges and inductive kickback without parameter drift or premature failure. |
| 150°C junction rating | Supports compact thermal design in sealed enclosures-no derating required up to +85°C ambient with minimal heatsinking. |
| Lead-free & halogen-free "Green" construction | Meets IPC-J-STD-020 Level 1 moisture sensitivity and RoHS 3 (2015/863/EU) without exemptions for Br/Cl/Sb content. |
Applications

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-30CPH01-M3 | Same 100 V VRRM, 15 A/leg, but TO-247AC package; RθJC = 2.0 °C/W; VF = 0.82 V @ 15 A. | Higher thermal performance but larger footprint; requires isolation washer for heatsink mounting. | Select when thermal budget is tighter than board space constraints; verify creepage/clearance for medical use. |
| ON Semiconductor MBR30H100CT | Same TO-220F-3 package; 100 V, 15 A/leg, but VF = 0.89 V @ 15 A; IR = 0.25 mA @ 100 V, +25°C. | Slightly higher conduction loss and leakage; qualified to AEC-Q101 for automotive. | Prefer for automotive-grade designs where qualification outweighs marginal VF penalty. |
Compared with VS-30CPH01-M3 and MBR30H100CT, MBR30100CTF-G1 offers optimal balance of low VF, TO-220F-3 insulation, and green compliance-ideal for space-constrained industrial and telecom power where thermal interface simplicity matters more than ultra-low RθJC.

FAQ
What is the maximum continuous forward current per anode terminal?
Each anode (Pin 1 and Pin 3) is rated for 15 A average forward current at TC = +107°C, with total device current capacity of 30 A when both legs operate simultaneously. Derating is required above +107°C case temperature per Figure 3 in DS36946 Rev. 4–2.
Can MBR30100CTF-G1 be used in place of a single 30 A Schottky diode?
No-it is a dual-diode device with separate anodes and shared cathode; it cannot replace a single-anode 30 A diode without circuit redesign. It is intended for center-tapped or dual-output topologies where two independent anode paths feed one common output node.
Is thermal pad soldering required for TO-220F-3 mounting?
Yes-the TO-220F-3 flange is electrically isolated but thermally conductive; optimal thermal performance requires soldering the metal tab to a large copper heatsink pad with ≥25 mm² area and thermal via array, per Diodes' recommended layout in package outline documentation.
Does this part meet AEC-Q101 for automotive use?
No-MBR30100CTF-G1 is not AEC-Q101 qualified. Diodes offers the MBR30H100CT variant for automotive applications; this part lacks PPAP documentation, IATF 16949 traceability, and extended temperature validation beyond +150°C TJ.
