Product details
Overview
MBR15100CT-E1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220-3 (2) package, rated for 100 V reverse voltage, 7.5 A per diode leg (15 A total), and 0.85 V forward voltage at 7.5 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification and power management circuits.
For engineers reviewing the MBR15100CT-E1 datasheet, MBR15100CT-E1 pinout, MBR15100CT-E1 application, or MBR15100CT-E1 equivalent, key selection criteria include its dual-diode common-cathode topology, 150°C junction temperature rating, 150 A non-repetitive surge capability, guard-ring stress protection, and RoHS-compliant lead-free finish.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal (Pin 2), enabling synchronous or interleaved rectification in dual-rail or center-tapped topologies. Its low VF and fast recovery support high-efficiency operation above 100 kHz without minority-carrier storage delay.
The TO-220-3 (2) package provides direct heatsink mounting with 2.5°C/W junction-to-case thermal resistance. The guard-ring structure enhances ruggedness against transient overvoltage and localized avalanche stress during line surges or inductive turn-off events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode leg; defines safe DC/peak AC operating margin in 48–72 V input SMPS designs. |
| IF(AV) per leg | 7.5 A - Average forward current rating per diode at TC = +122°C; supports continuous 15 A total output in dual-leg parallel configuration. |
| VF @ 7.5A, 25°C | 0.85 V - Measured forward drop at rated DC current; directly reduces conduction loss and improves efficiency vs. silicon PN rectifiers. |
| IFS(M) | 150 A - Non-repetitive peak surge current (60 Hz half-wave); withstands inrush and fault transients in industrial power supplies. |
| TJ max | +150°C - Maximum junction temperature; enables reliable operation in thermally constrained enclosures without derating below 125°C ambient. |
| RθJC | 2.5°C/W - Junction-to-case thermal resistance (TO-220-3); allows precise heatsink sizing using measured case temperature instead of ambient estimates. |
| IR @ 100V, 25°C | 0.1 mA - Max reverse leakage per diode; ensures minimal standby power loss in offline adapters and battery backup systems. |
Pinout & Package
Package: TO-220-3 (2), molded plastic case with matte tin–annealed copper leadframe, UL 94V-0 rated, 1.95 g weight. Mounting tab (Pin 2) is electrically connected to cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 (A1) | Input terminal for first diode leg; connects to transformer secondary or switching node in dual-output rectifier stage. |
| 2 | Common Cathode (K) | Shared cathode output node; electrically tied to metal tab; must be isolated from heatsink unless referenced to system ground. |
| 3 | Anode 2 (A2) | Input terminal for second diode leg; enables independent control or redundancy in dual-rail DC/DC outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.85 V @ 7.5 A, 25°C - Reduces conduction loss by ~35% versus comparable 100 V silicon rectifiers, improving full-load efficiency. |
| Guard-ring protected junction | Enhanced edge termination - Prevents premature avalanche breakdown at die periphery under voltage transients or mechanical stress. |
| High surge current rating | 150 A IFSM - Sustains repeated cold-start inrush without degradation, eliminating need for external surge limiters in 200 W+ supplies. |
| Pb-free & Green packaging | RoHS-compliant (E1 suffix), halogen/antimony-free - Meets IPC-1752A material declaration requirements for automotive and industrial OEMs. |
Applications
| Server PSU Output Rectification | Industrial DC/DC Converter |
|---|---|
Use Scenario: Dual +12 V and +5 V rails in 80 PLUS Titanium server power supplies operating at 250 kHz switching frequency. IC Role / Device Role / Timing Role: Dual-leg common-cathode Schottky rectifier replacing discrete diodes to reduce component count and layout area. Use Value: 0.85 V VF minimizes conduction loss across both rails simultaneously, enabling >96% efficiency at 50% load without forced air cooling. |
Use Scenario: Isolated 24 V input to ±15 V dual-output converter in PLC analog I/O modules. IC Role / Device Role / Timing Role: Synchronous rectification element in center-tapped forward topology with shared cathode return path. Use Value: 150°C TJ rating ensures stable operation in sealed enclosures up to 70°C ambient, eliminating thermal shutdown events. |
| Medical Power Adapter | Telecom Rectifier Module |
Use Scenario: Compact 60 W wall adapter for portable diagnostic equipment requiring low EMI and no audible noise. IC Role / Device Role / Timing Role: High-frequency output rectifier in quasi-resonant flyback design with <100 ns reverse recovery. Use Value: Near-zero reverse recovery charge eliminates snubber losses and reduces conducted EMI, easing CISPR-32 Class B compliance. |
Use Scenario: 48 V telecom rectifier module delivering 30 A to distributed DC bus with hot-swap capability. IC Role / Device Role / Timing Role: Primary-side rectifier in phase-shifted full-bridge topology with paralleled legs for current sharing. Use Value: 150 A IFSM withstands 200 A hot-swap insertion transients without bond-wire fusing or parameter shift. |
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-MBR15100CT | Same 100 V / 15 A rating but VF = 0.88 V @ 7.5 A; RθJC = 3.0°C/W; no guard ring specified. | Lacks documented guard-ring protection; higher VF increases conduction loss by ~35 mW per diode at full load. | Acceptable where cost sensitivity outweighs 0.3% efficiency penalty and surge margin is not critical. |
| ON Semiconductor MBR15100CT | Identical electrical specs but TO-220F-3 package option only; RθJC = 4.5°C/W; same E1 RoHS suffix. | Higher thermal resistance limits power density; requires larger heatsink or lower ambient for same TJ. | Preferred only when flange-isolated mounting is mandatory; otherwise MBR15100CT-E1 offers superior thermal performance. |
Compared with VS-MBR15100CT and ON's MBR15100CT, the Diodes MBR15100CT-E1 provides the lowest VF and best thermal resistance in standard TO-220-3, making it optimal for space-constrained, high-efficiency SMPS where thermal headroom and conduction loss are primary constraints.

FAQ
Is MBR15100CT-E1 suitable for use in automotive under-hood applications?
No. While rated for +150°C junction temperature, the MBR15100CT-E1 is not AEC-Q101 qualified and lacks automotive-specific qualification testing (e.g., HTOL, TCT, ESD HBM ≥15 kV). It is intended for industrial, computing, and telecom power systems-not safety-critical automotive environments.
Can Pin 2 (cathode tab) be electrically connected to the heatsink?
Yes, but only if the heatsink is electrically tied to the system ground reference. The metal tab is internally connected to Pin 2 (common cathode), so isolation is required if the cathode node is floating or referenced to a different potential than chassis ground.
What is the maximum recommended PCB copper area for thermal relief on the cathode pad?
Diodes recommends a minimum 100 mm² (10 mm × 10 mm) of 2 oz copper connected to the cathode pad via ≥4 thermal vias (0.3 mm diameter, filled) to an internal ground plane. This achieves near-datasheet RθJA of 60°C/W in still air.
Does MBR15100CT-E1 support bidirectional current flow?
No. As a Schottky rectifier, it conducts only from anode to cathode. Reverse conduction is blocked above 0.1 mA leakage at 100 V. It cannot function as a bidirectional switch or synchronous FET replacement without external circuitry.
