Product details

Overview

MBR20100CS2-G1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-263-2 surface-mount package, rated for 100 V reverse voltage, 10 A average forward current per diode leg (20 A total), 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-G1 datasheet, MBR20100CS2-G1 pinout, MBR20100CS2-G1 application, or MBR20100CS2-G1 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 isolated anodes and common cathode.

Technical Context

This dual Schottky rectifier integrates two independent 100 V, 10 A diode elements in a single TO-263-2 thermally enhanced package, sharing a common cathode terminal. Its guard-ring structure enhances ruggedness against voltage transients and mechanical stress.

Designed for medium-voltage, high-frequency operation, it supports continuous conduction mode (CCM) and discontinuous conduction mode (DCM) topologies. Junction temperature operates up to +150°C, with thermal resistance R_θJC = 2.0 °C/W and R_θJA = 50 °C/W on recommended PCB pad layout.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse blocking voltage per diode leg; defines safe operating ceiling in flyback or LLC resonant secondary-side rectification.
I_F(AV)	10 A per diode - Average forward current rating at T_C = +122°C; enables compact 20 A dual-output rectification without parallel devices.
V_F (max)	0.85 V @ 10 A, +25°C - Low forward drop reduces conduction loss by ~30% vs. standard silicon rectifiers, improving efficiency in 12–48 V output rails.
I_FSM	150 A - Non-repetitive surge current handling; sustains brief inrush or fault conditions in SMPS without degradation.
R_θJC	2.0 °C/W - Junction-to-case thermal resistance in TO-263-2 package; allows direct heatsinking via copper pour or external clip, enabling >15 W dissipation at ΔT = 30°C.
T_J (max)	+150°C - Maximum junction temperature; supports operation in enclosed industrial power supplies with ambient up to +85°C under proper layout.
I_R (max)	0.1 mA @ +25°C - Low reverse leakage ensures minimal standby power loss in energy-sensitive applications like IoT power bricks.

Pinout & Package

MBR20100CS2-G1 uses the TO-263-2 (D²Pak) surface-mount package: 10.66 mm × 15.87 mm body, 2.79 mm height, copper leadframe with matte tin annealed finish, UL 94V-0 molded compound, and 1.9 g weight. Thermal pad on underside requires soldered copper area per Diodes' recommended layout (X1=1.20 mm, Y2=8.56 mm, E=5.08 mm).

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first diode leg; electrically isolated from A2; connects to primary-side switching node in synchronous rectifier configurations.
A2	Anode 2	Input terminal for second diode leg; independent of A1; enables dual-output or interleaved rectification without cross-coupling.
K	Common Cathode	Shared output node for both diodes; routed to output capacitor ground plane; must be thermally anchored to ≥200 mm² 2-oz copper for optimal R_θJC.

Key Features

Feature	Design Value
Low V_F Schottky architecture	0.85 V max at 10 A ensures <1.5 W conduction loss per diode at full load-critical for meeting Level VI efficiency in 65 W adapters.
Guard-ring protected junction	Enhances ruggedness against dv/dt-induced turn-on and ESD events (>8 kV HBM), reducing field failure risk in unshielded industrial enclosures.
TO-263-2 thermal performance	R_θJC = 2.0 °C/W enables 15 W continuous dissipation with 30°C rise-eliminates need for discrete heatsinks in space-constrained 5G base station PSUs.
RoHS-compliant "Green" construction	Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); satisfies IEC 61249-2-21 and JEDEC J-STD-020 reflow compatibility requirements.
150 A I_FSM surge rating	Withstands 10× rated current for 8.3 ms (half-cycle 60 Hz), supporting robust startup in server VRMs with large bulk capacitance.

Applications

Use Scenario: 24 V/3 A dual-rail output in wall-mounted USB-C PD adapter with active clamp flyback topology.

IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier replacing two discrete 10A devices; common cathode simplifies PCB routing and reduces parasitic inductance.

Use Value: 0.85 V V_F cuts conduction loss by 1.2 W vs. Si diodes, enabling 92.5% efficiency at full load and eliminating forced air cooling.

Use Scenario: +12 V and +5 V outputs in 48 V input telecom half-brick DC/DC converter operating at 300 kHz.

IC Role / Device Role / Timing Role: Dual-leg synchronous rectification with independent anode control; supports phase-shifted ZVS operation.

Use Value: 150 A surge rating handles 200 µs inrush spikes during hot-swap insertion; 2.0 °C/W R_θJC maintains T_J < 120°C at 75°C ambient.

Industrial PLC Power Supply

LED Driver Secondary Side

Use Scenario: 24 V/10 A main rail in DIN-rail mounted programmable logic controller with wide-input (85–264 VAC) front-end.

IC Role / Device Role / Timing Role: High-frequency output rectifier in LLC resonant converter; dual-anode configuration isolates auxiliary and main outputs.

Use Value: Guard-ring protection prevents latch-up during 2 kV EFT bursts per IEC 61000-4-4; +150°C T_J rating ensures reliability in 70°C cabinet environments.

Use Scenario: Constant-current LED driver for street lighting with 48 V/5 A output and PWM dimming.

IC Role / Device Role / Timing Role: Low-noise freewheeling path during MOSFET off-time; dual-leg configuration enables redundant current paths.

Use Value: 0.1 mA I_R at +25°C minimizes standby current in always-on controllers; TO-263-2 footprint allows automated optical inspection (AOI) compatibility.

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-MBR20100CT	TO-220-3 through-hole package; R_θJC = 2.5 °C/W; same V_RRM/I_F(AV)/V_F specs.	Requires drilled mounting and manual heatsink attachment; less suitable for high-volume SMT lines.	Select when legacy through-hole assembly or higher mechanical robustness in vibration-prone environments is required.
ON Semiconductor MBR20100CT	TO-220F-3 insulated package; R_θJC = 4.5 °C/W; identical electrical ratings but lower thermal performance.	Limited to <10 W dissipation without external heatsink; unsuitable for sealed enclosures above 60°C ambient.	Choose only if electrical isolation from heatsink is mandatory and power density is below 8 W/cm².

Compared with VS-MBR20100CT and MBR20100CT, MBR20100CS2-G1 offers superior thermal management (2.0 °C/W vs. 2.5–4.5 °C/W) and automated assembly compatibility, making it optimal for high-efficiency, high-power-density SMT designs where board space and thermal headroom are constrained.

FAQ

What is the maximum allowable case temperature for continuous operation?

The datasheet specifies I_F(AV) = 10 A per diode at T_C = +122°C. Exceeding this temperature reduces current derating-operation above +122°C requires linear derating to zero at +150°C. For reliable 10 A operation, maintain T_C ≤ +122°C using the recommended TO-263-2 pad layout and ≥200 mm² 2-oz copper pour.

Can MBR20100CS2-G1 replace a single 20 A Schottky in a center-tapped transformer design?

No-it contains two independent 10 A diodes with separate anodes and a shared cathode, not a single 20 A device. In center-tapped configurations, it functions as dual half-wave rectifiers. To replace a 20 A single-diode part, use one anode-cathode path and leave the other unused, but thermal and layout advantages are forfeited.

Is the TO-263-2 package lead-free and halogen-free per JEDEC standards?

Yes-MBR20100CS2-G1 carries the "Green" designation: lead-free matte tin finish, <900 ppm bromine/chlorine, <1000 ppm antimony, and UL 94V-0 flammability rating. It complies with JEDEC J-STD-020 moisture sensitivity level 1 and RoHS Directive 2011/65/EU exemptions.

How does the guard-ring structure improve reliability in noisy industrial environments?

The integrated guard ring suppresses edge leakage currents and prevents premature avalanche breakdown under high dv/dt transients (rated 10,000 V/µs). This mitigates false turn-on during switching node ringing and improves immunity to 2 kV EFT bursts per IEC 61000-4-4, extending MTBF in motor drive and factory automation systems.
