Product details
Overview
MBRS20200CT-Y from Taiwan Semiconductor is a 20 A, 200 V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion with 0.99 V max forward voltage at 10 A and 25°C, 5 mA max reverse leakage at 125°C, and 150 A surge capability - deployed in industrial SMPS and telecom power modules.
For engineers reviewing the MBRS20200CT-Y datasheet, MBRS20200CT-Y pinout, MBRS20200CT-Y application, or MBRS20200CT-Y equivalent, key selection criteria include verified 200 V repetitive peak reverse voltage, junction-to-case thermal resistance of 2.0 °C/W, dual common-cathode configuration, RoHS/halogen-free compliance, and TO-263AB mechanical compatibility with automated SMT placement.
Technical Context
This dual-die Schottky rectifier integrates two independent 200 V/20 A diodes in a common-cathode configuration within a single TO-263AB thermally enhanced package. Its low forward voltage (0.99 V max @ 10 A, 25°C) and low reverse recovery charge enable high-frequency switching efficiency in hard-switched topologies.
The device features guard ring overvoltage protection, JESD201 Class 1A whisker resistance, and moisture sensitivity level 1 - confirming suitability for reflow-soldered industrial power assemblies requiring long-term thermal stability up to 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage withstand without breakdown, defining safe operating range in 48 V–60 V bus-derived DC/DC stages |
| IF | 20 A - continuous average forward current per diode, supporting high-power density rectification in compact layouts |
| VF (max) | 0.99 V @ 10 A, 25°C - directly reduces conduction loss and thermal load in primary-side synchronous rectification |
| IR (max) | 5 mA @ 200 V, 125°C - ensures minimal standby leakage in high-temperature ambient environments |
| RθJC | 2.0 °C/W - enables direct heatsinking to PCB copper or external metal slug, critical for thermal management in sealed enclosures |
| IFSM | 150 A - handles inrush and transient surges without degradation, supporting robust startup in server PSUs |
| TJ max | 150 °C - allows operation in extended-temperature industrial applications without derating below full rated current |
Pinout & Package
TO-263AB (D2PAK) surface-mount package with exposed thermal pad on underside; three terminals: Anode 1, Cathode (common), Anode 2 - configured as dual common-cathode Schottky rectifier.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR20200CT | Same 200 V/20 A rating, but RθJC = 2.2 °C/W; VF = 1.05 V max @ 10 A, 25°C | Slightly higher conduction loss and thermal resistance - requires larger copper area for equivalent cooling | Acceptable where board space permits minor thermal margin adjustment |
| ON Semiconductor MBR20200CT | Identical electrical specs and TO-263AB footprint; datasheet specifies 0.95 V VF typ @ 10 A, 25°C (vs. 0.99 V max for MBRS20200CT-Y) | No layout change needed; tighter VF distribution may improve efficiency consistency across production lots | Drop-in alternative if tighter VF binning is prioritized for efficiency-critical designs |
Compared with VS-MBR20200CT and MBR20200CT, MBRS20200CT-Y offers the lowest specified VF maximum (0.99 V), best thermal resistance (2.0 °C/W), and guaranteed halogen-free construction - making it optimal for thermally constrained, high-reliability industrial power supplies.

FAQ
What is the maximum junction temperature rating for MBRS20200CT-Y?
The MBRS20200CT-Y has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This rating allows uninterrupted 20 A continuous operation in industrial environments where ambient temperatures reach 85°C, provided thermal design maintains junction rise within limits. The MBRS20200CT-Y's 2.0 °C/W RθJC supports this performance when mounted on ≥4 cm² 2-oz copper with thermal vias.
Is MBRS20200CT-Y compatible with lead-free reflow soldering processes?
Yes, MBRS20200CT-Y is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated Level 1 per J-STD-020 - meaning no baking is required prior to assembly. The MBRS20200CT-Y's UL 94V-0 molding compound also withstands peak reflow temperatures up to 260°C for 30 seconds without delamination or marking degradation.
Does MBRS20200CT-Y have a common-cathode or common-anode configuration?
The MBRS20200CT-Y uses a dual common-cathode configuration: two independent anodes (Pin 1 and Pin 3) share a single cathode terminal (Pin 2). This architecture is confirmed in the device marking diagram and mechanical outline drawing in the Taiwan Semiconductor datasheet. The MBRS20200CT-Y's pinout enables efficient dual-output rectification without external wiring, reducing parasitic inductance in high-frequency SMPS designs.
What is the reverse leakage current specification for MBRS20200CT-Y at elevated temperature?
At rated 200 V reverse voltage and 125°C junction temperature, MBRS20200CT-Y exhibits a maximum reverse leakage current (IR) of 5 mA per diode - specified in the Electrical Specifications table. This value is measured under 30 ms pulse conditions and reflects worst-case behavior in hot, high-voltage operating environments such as telecom rectifiers. At 25°C, IR is limited to 100 µA max, ensuring low standby loss in always-on systems.
Can MBRS20200CT-Y replace MBRS20150CT-Y in an existing design?
Yes, MBRS20200CT-Y can directly replace MBRS20150CT-Y because both share identical TO-263AB package, pinout, thermal characteristics (RθJC = 2.0 °C/W), and electrical parameters except VRRM - increased from 150 V to 200 V. No PCB or firmware changes are needed. The MBRS20200CT-Y's higher voltage rating improves margin against line transients, making it a robust upgrade path for legacy 150 V designs operating near their voltage limit.
