Product details
Overview
MBR20100CS2TR-E1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-263-2 (D2PAK) 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 switch-mode power supplies and DC-DC converters.
For engineers reviewing the MBR20100CS2TR-E1 datasheet, MBR20100CS2TR-E1 pinout, MBR20100CS2TR-E1 application, or MBR20100CS2TR-E1 equivalent, key selection criteria include dual-diode thermal resistance (2.0 °C/W junction-to-case), 150 °C max operating junction temperature, RoHS-compliant "Green" packaging, and surge capability of 150 A non-repetitive peak forward current.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V / 10 A diode elements in a single surface-mount TO-263-2 package. Its guard-ring structure enhances ruggedness against transient stress, while the low VF enables high-efficiency rectification in medium-voltage, high-frequency power conversion stages.
The device operates up to +150°C junction temperature with 2.0 °C/W thermal resistance (junction-to-case) when mounted on recommended PCB copper area. Reverse leakage remains ≤0.1 mA at +25°C and ≤6.0 mA at +125°C under rated DC blocking voltage, supporting stable performance across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode can block without breakdown. |
| IF(AV) per leg | 10 A - Continuous average forward current per diode at TC = +122°C, defining usable output power capacity. |
| VF (max) | 0.85 V @ 10 A, +25°C - Low conduction loss enabling >92% efficiency in 12 V–48 V output rectification. |
| IFS M | 150 A - Non-repetitive surge current handling supports inrush tolerance in AC/DC front-end and PFC stages. |
| RθJC | 2.0 °C/W - Junction-to-case thermal resistance confirms effective heat transfer to heatsink or PCB copper pour. |
| TJ(max) | +150°C - Maximum junction temperature allows operation in compact, thermally constrained industrial enclosures. |
| IR (max) | 0.1 mA @ +25°C - Ultra-low reverse leakage preserves standby power budget in energy-sensitive applications. |
Pinout & Package
MBR20100CS2TR-E1 uses the TO-263-2 (D2PAK) surface-mount package with exposed cathode tab for thermal and electrical connection. The package measures 15.87 mm × 10.66 mm × 4.82 mm and weighs ~1.9 g. Cathode-side mounting requires solderable matte tin finish on copper leadframe per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode leg; connects to high-side switching node in center-tapped or dual-output topologies. |
| A2 | Anode 2 | Input terminal for second Schottky diode leg; enables independent or interleaved rectification paths. |
| K | Common Cathode | Shared output node tied to ground or return rail; electrically and thermally coupled to large copper pad for heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 0.85 V max @ 10 A ensures <1.5 W conduction loss per leg at full load, reducing thermal design burden. |
| Guard-ring protected junction | Enhances ruggedness against dv/dt-induced avalanche and ESD transients (>8 kV HBM), improving field reliability. |
| TO-263-2 thermal performance | 2.0 °C/W RθJC enables 10 A continuous operation with ≤40°C temperature rise above case under proper PCB layout. |
| RoHS-compliant "Green" construction | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IEC 61249-2-21 and JEDEC J-STD-020. |
| High surge rating | 150 A IFSM supports 10× nominal current for 1 cycle, accommodating startup surges in server PSUs and telecom rectifiers. |
Applications
| Server AC/DC Power Supplies | Industrial DC-DC Converters |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in 48 V input, 12 V/54 A output server PSU modules. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier replacing MOSFETs in OR-ing and output stage, leveraging low VF for efficiency. Use Value: Reduces conduction loss by 35% vs. standard silicon diodes, lowering thermal load on heatsink and enabling higher power density. |
Use Scenario: Output rectification in isolated 24 V → 5 V/20 A industrial DC-DC converters with wide ambient range (-40°C to +85°C). IC Role / Device Role / Timing Role: Common-cathode dual diode providing parallel path redundancy and thermal sharing between two output rails. Use Value: Maintains <0.2 V reverse leakage at +85°C, preserving no-load regulation and minimizing standby power waste. |
| Telecom Rectifier Modules | Programmable Power Supplies |
|

IC Role / Device Role / Timing Role: High-surge-capable Schottky rectifier handling repetitive line transients and hot-swap events. Use Value: Withstands 150 A non-repetitive surge without degradation, eliminating need for external TVS clamping in many designs. |
Use Scenario: Multi-rail lab-grade power supply with independently regulated ±15 V and +5 V outputs. IC Role / Device Role / Timing Role: Dual-leg rectifier feeding separate linear post-regulators, minimizing cross-talk via isolated anode paths. Use Value: 0.85 V VF matching between legs (<5% mismatch) ensures balanced current sharing and stable load regulation. |
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-263AB package with slightly higher VF (0.88 V @ 10 A) and RθJC (2.5 °C/W). | Lower thermal performance limits continuous current in space-constrained layouts without enhanced copper pour. | Select when legacy Vishay footprint compatibility is required; verify thermal margin with 2.5 °C/W RθJC. |
| ON Semiconductor MBR20100CT | TO-220-3 through-hole variant with identical electrical specs but higher RθJA (60 °C/W) and no surface-mount thermal pad. | Requires mechanical heatsink mounting; unsuitable for high-density automated assembly or low-profile designs. | Choose only for through-hole prototyping or legacy board rework where TO-220 mounting is mandated. |
Compared with VS-20BQ100-M3/45 and MBR20100CT, MBR20100CS2TR-E1 offers superior thermal interface via TO-263-2's low 2.0 °C/W RθJC and optimized solderable cathode tab-critical for high-power density, reflow-compatible production.

FAQ
What is the maximum junction temperature and how does it affect thermal design?
The MBR20100CS2TR-E1 has a maximum junction temperature of +150°C. With its 2.0 °C/W junction-to-case thermal resistance, maintaining case temperature ≤110°C ensures 40°C safety margin. This requires ≥11.6 cm² of 2-oz copper on the cathode pad per Diodes' recommended layout for TO-263-2.
Is MBR20100CS2TR-E1 suitable for synchronous rectification replacement?
No-it is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. However, its low 0.85 V VF makes it a direct drop-in replacement for standard silicon diodes in non-controlled rectification stages where gate drive complexity must be avoided.
How does the guard-ring structure improve reliability in power supplies?
The integrated guard-ring mitigates edge leakage and prevents premature avalanche breakdown under high dv/dt conditions (rated 10,000 V/µs). This reduces failure risk during MOSFET switching transitions and improves long-term stability in SMPS with fast-switching GaN or SiC primary-side devices.
What is the difference between "E1" and "G1" suffixes in Diodes' ordering codes?
"E1" denotes RoHS-compliant finish (lead-free, annealed matte tin); "G1" adds halogen- and antimony-free "Green" qualification (<900 ppm Br/Cl, <1000 ppm Sb). Both meet EU RoHS 2011/65/EU, but G1 satisfies stricter environmental mandates like JEDEC J-STD-020 and IPC-1752A.
