Product details
Overview
MBR20100CD-E1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-252-2 (DPAK) package, rated for 100 V reverse voltage, 10 A average forward current per diode leg, and 0.85 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 AC/DC adapters and DC/DC modules.
For engineers reviewing the MBR20100CD-E1 datasheet, MBR20100CD-E1 pinout, MBR20100CD-E1 application, or MBR20100CD-E1 equivalent, key selection criteria include its dual-diode configuration, 150°C junction temperature rating, 150 A non-repetitive surge capability, thermal resistance of 2.0 °C/W (junction-to-case), and RoHS-compliant green packaging.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V / 10 A diode elements sharing a single cathode terminal. Its guard-ring structure enhances ruggedness against transient overvoltage stress, while the low VF enables high-efficiency operation in medium-voltage, high-frequency SMPS topologies.
The device operates up to +150°C junction temperature and exhibits <0.1 mA reverse leakage at +25°C under rated DC blocking voltage. Its 10,000 V/µs voltage rate-of-change rating supports fast-switching applications without parasitic turn-on.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode can block reliably in circuit |
| IF(AV) per leg | 10 A - Continuous DC output current per diode leg at TC = +122°C, defining thermal design margin |
| VF (max) | 0.85 V @ 10 A, +25°C - Directly determines conduction loss and thermal load in high-current paths |
| IR (max) | 0.1 mA @ 100 V, +25°C - Low leakage preserves efficiency in standby and light-load conditions |
| IFSM | 150 A - Peak surge current handling capability during power-up or fault transients |
| TJ(max) | +150°C - Enables compact heatsinking in space-constrained industrial and telecom power supplies |
| RθJC | 2.0 °C/W - Confirmed for TO-252-2 package; defines minimum heatsink requirement for thermal management |
Pinout & Package
MBR20100CD-E1 uses the TO-252-2 (DPAK) surface-mount package with three terminals: two anodes (A1, A2) and one shared cathode (K). The package features matte tin-plated copper leadframe, halogen-free green molding compound (UL 94V-0), and weighs approximately 0.31 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode Leg 1 | Input terminal for first rectification path; connects to transformer secondary or switching node |
| A2 | Anode of Diode Leg 2 | Input terminal for second independent rectification path; enables dual-output or interleaved designs |
| K | Common Cathode | Shared output node; routes combined DC output to filter capacitor and load; requires low-inductance layout |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode Schottky topology | Enables synchronous dual-output rectification or interleaved phase operation without external cathode tying |
| Guard-ring protected junction | Improves reliability under repetitive voltage transients and line surges in offline SMPS applications |
| RoHS-compliant "Green" package | TO-252-2 with halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) |
| +150°C maximum junction temperature | Supports operation in thermally demanding environments (e.g., enclosed telecom PSUs) without derating |
| Low thermal resistance (RθJC = 2.0 °C/W) | Allows direct PCB copper pour heatsinking-no mechanical clip or additional thermal interface needed |
Applications
| AC/DC Adapter Output Stage | Telecom DC/DC Converter Secondary |
|---|---|
|

Use Value: <0.1 mA IR at +25°C maintains low standby power; TO-252-2 footprint fits tight LED module layouts. |
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-20BQ100-M3/45 | Same 100 V / 2×10 A rating, but TO-263-2 package (RθJC = 2.0 °C/W); VF = 0.78 V @ 10 A, +25°C | Requires larger PCB footprint; better suited for forced-air-cooled systems | Select when higher surge margin (200 A IFSM) and lower VF are prioritized over DPAK compatibility |
| ON Semiconductor MBR20100CT | TO-220-3 through-hole package; identical electrical specs but RθJC = 2.5 °C/W and higher mounting complexity | Used where mechanical stability or legacy through-hole assembly is required | Choose only if board-level reworkability or heat sink clamping is mandatory |
Compared with VS-20BQ100-M3/45 and MBR20100CT, MBR20100CD-E1 offers optimal balance of surface-mount manufacturability, thermal performance in DPAK, and proven reliability in high-volume adapter designs-without requiring layout redesign or thermal derating.

FAQ
What is the maximum continuous current per diode leg for MBR20100CD-E1?
The MBR20100CD-E1 supports 10 A average rectified forward current per diode leg at case temperature TC = +122°C. This rating assumes proper PCB copper area per Diodes' recommended pad layout (11.6 mm × 7.0 mm thermal pad) and ambient conditions that maintain junction temperature ≤ +150°C.
Does MBR20100CD-E1 have a common-cathode or common-anode configuration?
MBR20100CD-E1 uses a common-cathode configuration: pins A1 and A2 are independent anodes, and pin K is the shared cathode. This arrangement is confirmed in the datasheet's front-view pin diagram for TO-252-2 and is essential for dual-output or center-tapped transformer applications.
Is MBR20100CD-E1 suitable for use in automotive power supplies?
MBR20100CD-E1 is not AEC-Q101 qualified and lacks automotive-specific qualification data (e.g., HTOL, temperature cycling). While its +150°C TJ rating meets under-hood thermal requirements, Diodes Incorporated does not specify it for automotive safety-critical systems per their life support notice.
How does the TO-252-2 package of MBR20100CD-E1 compare thermally to TO-220 variants?
MBR20100CD-E1 in TO-252-2 has RθJC = 2.0 °C/W-lower than TO-220-3 (2.5 °C/W) and TO-220F-3 (4.5 °C/W). Its thermal performance relies on soldered copper pad area rather than mechanical heatsinks, making it ideal for compact, high-density PCBs where airflow is limited.
