Product details
Overview
MBR20100CTF-E1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 10 A average forward current per diode leg, and 0.85 V max forward voltage at +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR20100CTF-E1 datasheet, MBR20100CTF-E1 pinout, MBR20100CTF-E1 application, or MBR20100CTF-E1 equivalent, key selection criteria include thermal resistance (4.5 °C/W junction-to-case), surge capability (150 A non-repetitive peak), RoHS-compliant lead-free finish, and dual-diode common-cathode configuration for compact power stage design.
Technical Context
This dual Schottky rectifier integrates two independent 100 V / 10 A diode elements in a single TO-220F-3 thermally enhanced package with insulated tab. Its guard-ring structure enhances ruggedness against transient overstress, while the low VF enables high-efficiency operation in 100–500 kHz switch-mode 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 risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 100 V - Maximum repetitive reverse voltage each diode can block reliably in continuous operation |
| IF(AV) per leg | 10 A - Average forward current per diode at TC = +122°C, defining usable DC output capacity |
| VF (max) | 0.85 V @ 10 A, +25°C - Low conduction loss enabling >92% efficiency in 12 V output rails |
| IR (max) | 0.1 mA @ 100 V, +25°C - Minimal leakage preserves standby power budget in energy-sensitive designs |
| RθJC | 4.5 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting without thermal pad compromise |
| IFSM | 150 A - Non-repetitive surge current rating supports cold-start inrush handling in AC/DC front-ends |
| TJ range | −65°C to +150°C - Wide operating junction temperature supports industrial and automotive under-hood environments |
Pinout & Package
MBR20100CTF-E1 uses the TO-220F-3 (Option 1) package: insulated plastic case with three terminals, metal tab electrically isolated, optimized for forced-air or heatsink-cooled operation. Dimensions: 14.7–16.0 mm length × 6.9–7.1 mm width × 3.0–3.4 mm height (front view).

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-20CPH06-M3 | 60 V VRRM, same TO-220F-3 package, 0.72 V VF @ 10 A | Limited to ≤60 V systems; unsuitable for 100 V bus designs | Select only when lower voltage rating is acceptable and lower VF is prioritized |
| ON Semiconductor MBR20100CT | Same 100 V/10 A rating but TO-220-3 (non-insulated tab) package, RθJC = 2.5 °C/W | Requires insulating hardware for heatsink mounting; higher thermal performance but lower isolation safety | Choose when thermal priority outweighs electrical isolation needs and mechanical insulation is managed externally |
Compared with VS-20CPH06-M3 and MBR20100CT, MBR20100CTF-E1 uniquely balances 100 V blocking, TO-220F-3 insulation, and 4.5 °C/W thermal resistance-making it optimal for safety-critical, medium-voltage industrial SMPS where creepage, thermal margin, and voltage headroom must coexist.

FAQ
What is the thermal resistance from junction to case (RθJC) for MBR20100CTF-E1?
The junction-to-case thermal resistance is 4.5 °C/W, measured under standard test conditions with the device mounted on a heatsink. This value reflects the TO-220F-3 package's insulated construction and enables accurate thermal modeling for heatsink sizing in continuous 20 A total output applications.
Can MBR20100CTF-E1 replace a single-diode Schottky in an existing design?
No-it is a dual-anode, common-cathode Schottky rectifier. Replacing a single diode requires verifying circuit topology compatibility: the shared cathode must align with the existing output rail, and both anodes must connect to appropriate input nodes (e.g., center-tapped transformer or interleaved phases). Direct substitution without layout review risks short circuits or reverse bias damage.
Is the TO-220F-3 package electrically insulated?
Yes-the TO-220F-3 variant features a fully insulated metal tab, rated for ≥2500 V RMS isolation between tab and internal terminals. This eliminates need for insulating washers when mounting directly to grounded heatsinks, simplifying mechanical assembly and improving thermal reliability in safety-critical power systems.
What is the maximum allowable case temperature for continuous operation?
The maximum recommended case temperature is +122°C, derived from the 10 A average forward current rating per diode leg. Exceeding this temperature requires proportional current derating per the curve in Figure 3 of DS36950 Rev. 5–2, with absolute maximum junction temperature capped at +150°C regardless of case condition.
