Product details
Overview
MBR20150SCTF-G1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-220F-3 package, rated for 150 V reverse voltage, 10 A average forward current per diode leg (20 A total), and 0.9 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 SMPS output rectification and industrial power management systems.
For engineers reviewing the MBR20150SCTF-G1 datasheet, MBR20150SCTF-G1 pinout, MBR20150SCTF-G1 application, or MBR20150SCTF-G1 equivalent, key selection criteria include its dual-common-cathode configuration, 150°C junction temperature rating, 150 A non-repetitive surge capability, and RoHS-compliant matte tin finish on copper leadframe.
Technical Context
This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a common cathode (K), enabling synchronous or interleaved rectification topologies without external parallel diodes. Its guard-ring structure enhances ruggedness against transient overvoltage stress.
Designed for medium-voltage, high-frequency operation, it supports dv/dt up to 10,000 V/µs and exhibits <0.05 mA reverse leakage at +25°C - critical for maintaining efficiency in compact, thermally constrained power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage each diode can block without breakdown. |
| IF(AV) per leg | 10 A - Continuous average forward current per anode-cathode path at TC = +134°C. |
| VF (max) | 0.9 V @ 10 A, +25°C - Low conduction loss enables high-efficiency rectification in 12–48 V output rails. |
| IR (max) | 0.05 mA @ VR = 150 V, +25°C - Minimal leakage preserves standby power budget in energy-sensitive designs. |
| IFS M | 150 A - Non-repetitive surge current handling ensures robustness during line transients or startup inverter spikes. |
| TJ operating range | −55°C to +150°C - Enables deployment in automotive under-hood or industrial ambient environments. |
| RθJC | 3.0 °C/W - Thermal resistance from junction to case (TO-220F-3) dictates minimum heatsink requirement for thermal design. |
Pinout & Package
Package: TO-220F-3 - Insulated plastic case with flanged mounting tab, UL 94V-0 rated molding compound, and matte tin-plated copper leadframe. Weight: 1.69 g (approx).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode 1 | Input terminal for first Schottky diode leg; connects to primary-side switching node in dual-output or phase-interleaved SMPS. |
| 2 (K) | Common Cathode | Shared output node for both diodes; ties directly to output capacitor negative rail or ground reference in center-tapped configurations. |
| 3 (A2) | Anode 2 | Input terminal for second Schottky diode leg; enables independent control of two power paths or redundancy in fault-tolerant supplies. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.9 V @ 10 A, +25°C - Reduces conduction loss by ~30% vs. standard silicon rectifiers at same rating. |
| Guard-ring protection | Integrated edge termination - Prevents premature avalanche failure under voltage transients or localized ESD events. |
| High TJ rating | +150°C maximum junction temperature - Allows operation in sealed enclosures or high-ambient industrial settings without derating. |
| RoHS/Green compliance | Lead-free, halogen-free, antimony-free - Meets IEC 61249-2-21 and JEDEC J-STD-020 Level 1 moisture sensitivity requirements. |
| ESD robustness | 8 kV HBM, >400 V MM - Eliminates need for external ESD protection in board-level assembly handling and field service. |
Applications
| Server Power Supply | Industrial Motor Drive |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in 48 V input, 12 V/20 A output server PSUs. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing MOSFETs in low-side synchronous topology to reduce gate drive complexity and improve light-load efficiency. Use Value: 0.9 V VF minimizes conduction loss at full load, while 150 A IFSM withstands inrush surges during hot-swap module insertion. |
Use Scenario: DC bus freewheeling and regeneration clamping in 3-phase IGBT-based motor drives. IC Role / Device Role / Timing Role: Bidirectional clamp diode pair across DC link capacitors to absorb regenerative energy during braking. Use Value: 150 V VRRM safely blocks peak bus voltages up to 135 V DC; 3.0 °C/W RθJC enables direct heatsink mounting without thermal interface pads. |
| Telecom Rectifier Module | Medical Imaging Power System |
|
Use Scenario: Output rectification in -48 V telecom rectifier modules operating at 200 kHz switching frequency. IC Role / Device Role / Timing Role: High-frequency rectifier minimizing reverse recovery noise and EMI generation in tightly regulated outputs. Use Value: Near-zero reverse recovery charge eliminates snubber circuits; 10,000 V/µs dv/dt rating prevents false triggering in noisy RF-rich environments. |
Use Scenario: Isolated auxiliary supply rectification in MRI gradient amplifier subsystems requiring ultra-low leakage. IC Role / Device Role / Timing Role: Dual-path rectifier feeding isolated +5 V and +3.3 V rails for FPGA and ADC biasing with minimal cross-talk. Use Value: 0.05 mA IR at +25°C ensures <1 µW leakage per leg - critical for preserving signal integrity in low-noise analog front-ends. |
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-MBR20150CT | Same 150 V/10 A per leg, but TO-220AB package (non-insulated); RθJC = 2.5 °C/W. | Lacks molded insulation - requires isolation hardware for chassis-grounded heatsinks. | Select when mechanical clearance allows direct metal heatsink contact and lower thermal resistance is prioritized. |
| ON Semiconductor MBR20150CT | Identical electrical specs, but TO-220-3 (2) package; RθJC = 2.0 °C/W; no halogen-free certification. | Higher thermal performance but non-Green finish - unsuitable for EU medical or automotive programs. | Select for cost-sensitive industrial applications where RoHS 3 and halogen-free compliance are not mandated. |
Compared with VS-MBR20150CT and MBR20150CT, MBR20150SCTF-G1 trades 0.5–1.0 °C/W higher thermal resistance for built-in electrical isolation and full halogen/antimony-free compliance - essential for safety-critical and export-regulated designs.

FAQ
What is the thermal resistance from junction to ambient (RθJA) for MBR20150SCTF-G1?
The datasheet specifies RθJA = 60 °C/W for TO-220F-3 mounting on a standard PCB with minimum recommended pad layout. This value assumes no external heatsink; actual RθJA improves significantly with a properly sized heatsink attached to the insulated tab.
Can MBR20150SCTF-G1 be used in place of a single-diode TO-220 Schottky?
No - MBR20150SCTF-G1 contains two independent Schottky diodes sharing a common cathode (A1-K-A2). Replacing a single-diode part requires verifying circuit topology compatibility, especially whether the design uses dual inputs or requires separate cathodes.
Is the TO-220F-3 package electrically insulated?
Yes - the TO-220F-3 variant features a fully insulated plastic case. The mounting tab is electrically isolated from all three terminals, enabling direct attachment to grounded heatsinks without additional insulating hardware.
What does the "G1" suffix indicate in MBR20150SCTF-G1?
The "G1" suffix denotes RoHS-compliant, lead-free, halogen-free, and antimony-free construction per Diodes Incorporated's Green definition - including <900 ppm bromine/chlorine and <1000 ppm antimony compounds in the molding compound and plating.
