Product details
Overview
MBR20100CS2-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 power converters such as AC/DC adapters and DC/DC modules.
For engineers reviewing the MBR20100CS2-E1 datasheet, MBR20100CS2-E1 pinout, MBR20100CS2-E1 application, or MBR20100CS2-E1 equivalent, key selection criteria include thermal resistance (2.0 °C/W junction-to-case), surge capability (150 A non-repetitive peak), RoHS-compliant green packaging, and dual-diode configuration with common-cathode topology.
Technical Context
This dual Schottky rectifier integrates two independent 100 V / 10 A diode elements in a single TO-263-2 surface-mount package with common cathode connection. Its guard-ring structure enhances ruggedness against transient overvoltage stress, while the low VF enables high-efficiency operation in medium-voltage, high-frequency switch-mode topologies.
The device operates up to +150°C junction temperature and exhibits <0.1 mA reverse leakage at +25°C and 6.0 mA at +125°C under rated DC blocking voltage. Its 10,000 V/µs voltage rate of change 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 continuous operation. |
| IF(AV) per leg | 10 A - Average forward current per diode leg 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 12–48 V output rectification stages. |
| IR (max) | 0.1 mA @ +25°C - Minimal leakage preserves standby power integrity in energy-sensitive designs. |
| RθJC | 2.0 °C/W - Enables direct heatsinking to PCB copper area for thermal management without external heatsink. |
| IFSM | 150 A - Withstands brief inrush surges during cold-start or line transients without degradation. |
| TJ range | −65°C to +150°C - Supports industrial and extended-temperature embedded power systems. |

Use Value: −65°C to +150°C storage and operating range ensures reliability across outdoor lighting thermal cycles. |
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 2.5 °C/W RθJC and 0.88 V VF @ 10 A. | Slightly higher VF increases conduction loss by ~3.5% at full load; identical pinout and footprint. | Select when legacy Vishay qualification or alternate supply chain is required. |
| ON Semiconductor MBR20100CT | TO-220-3 through-hole variant; 2.5 °C/W RθJC, same VF/IR specs, but requires heatsink mounting. | Not surface-mount compatible; unsuitable for automated assembly or high-density PCBs. | Choose only for prototyping or low-volume through-hole designs where thermal mass is available. |
Compared with VS-20BQ100-M3/45 and MBR20100CT, MBR20100CS2-E1 offers superior thermal resistance (2.0 vs. 2.5 °C/W) and optimized surface-mount manufacturability, making it preferred for high-power density production designs.

FAQ
What is the pin configuration for MBR20100CS2-E1 in TO-263-2 package?
Pin 1 is Anode 1 (A1), Pin 2 is Common Cathode (K), and Pin 3 is Anode 2 (A2), viewed from top with marking side up and leads down. This common-cathode dual-diode layout supports full-wave and dual-output rectification without external wiring.
Can MBR20100CS2-E1 replace standard silicon rectifiers in existing designs?
Yes, provided the circuit operates below 100 V reverse voltage and benefits from lower forward drop. Its 0.85 V VF reduces conduction loss versus 1.1 V silicon diodes, but note its higher reverse leakage at elevated temperatures-verify thermal design and no-load regulation.
Is MBR20100CS2-E1 suitable for automotive applications?
No-it is not AEC-Q101 qualified. While it operates from −65°C to +150°C, Diodes Incorporated does not certify this part for automotive use due to lack of stress testing per AEC standards and absence of PPAP documentation.
What PCB layout guidance applies to MBR20100CS2-E1's thermal pad?
The TO-263-2 exposed pad must be soldered to ≥4 cm² of 2-oz copper with ≥6 thermal vias (0.3 mm diameter) to internal ground planes. Per Diodes' recommended layout, X1 = 1.20 mm, Y1 = 3.83 mm, and E = 5.08 mm define minimum pad dimensions for optimal RθJA reduction.
