Product details
Overview
MBRS20100CT-Y from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20A average forward current, 100V repetitive peak reverse voltage, and 150A non-repetitive surge current; it delivers 0.85V max forward voltage at 10A/25°C and operates up to 150°C junction temperature, used in high-efficiency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the MBRS20100CT-Y datasheet, MBRS20100CT-Y pinout, MBRS20100CT-Y application, or MBRS20100CT-Y equivalent, key selection criteria include its 100V VRRM, dual-common-cathode configuration, 2.0°C/W junction-to-case thermal resistance, low IRR (≤5mA at 125°C), and RoHS/halogen-free compliance for industrial power supply designs.
Technical Context
This dual Schottky rectifier integrates two independent diode dies in a single common-cathode configuration, enabling synchronous or parallel rectification in center-tapped or full-wave topologies. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.
The device supports high-frequency switching with 10,000 V/μs critical dv/dt rating and exhibits low junction capacitance - typical values scale inversely with voltage rating across the MBRS20xCT-Y family, with MBRS20100CT-Y optimized for 100V-class SMPS output stages requiring fast recovery and minimal conduction loss.
Key Specifications

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-20CPH06-M3 | 60V VRRM, same 20A/150A ratings, TO-263AB package, but higher VF (0.82V typ @ 10A) | Not suitable for 100V bus applications; limited to ≤60V output rails | Select only when system VR ≤60V and lower VF at high TJ is not required |
| ON Semiconductor MBR20100CT | Same 100V/20A rating, identical TO-263AB package and pinout, but 2.5°C/W RθJC and no guard ring | Slightly higher thermal resistance requires larger copper area; less robust under voltage transients | Acceptable drop-in alternative if layout includes ≥200mm² thermal pad and transient clamping is externally implemented |
Compared with VS-20CPH06-M3 and MBR20100CT, MBRS20100CT-Y offers superior 100V blocking margin, lower thermal resistance (2.0°C/W), and integrated guard ring protection - making it preferred for 48V–100V industrial and telecom power systems where reliability and thermal headroom are critical.

FAQ
What is the maximum junction temperature rating for MBRS20100CT-Y?
The MBRS20100CT-Y has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version E2201. This allows reliable operation in sealed enclosures or high-ambient environments such as industrial motor drives and telecom power shelves where ambient temperatures exceed 85°C. Derating curves confirm usable current capacity down to 12A at 125°C case temperature.
Does MBRS20100CT-Y have a common-cathode or common-anode configuration?
MBRS20100CT-Y uses a common-cathode configuration: Pin 2 is the shared cathode terminal, while Pins 1 and 3 serve as independent anodes for the two internal Schottky dies. This configuration is confirmed in the marking diagram, mechanical outline, and electrical specifications tables of the Taiwan Semiconductor datasheet. It enables full-wave rectification in center-tapped transformer designs and simplifies output filtering in dual-rail supplies.
What is the forward voltage specification for MBRS20100CT-Y at elevated temperature?
Per the Electrical Specifications table in the Taiwan Semiconductor datasheet, MBRS20100CT-Y has a maximum forward voltage (VF) of 0.75 V at 10A and 125°C junction temperature. This value reflects reduced conduction loss at high operating temperatures - a key advantage over silicon rectifiers - and supports stable efficiency in thermally demanding applications like enclosed power adapters and PLC power modules.
Is MBRS20100CT-Y suitable for use in automotive applications?
MBRS20100CT-Y is not qualified to AEC-Q101 or automotive-grade reliability standards, and Taiwan Semiconductor explicitly states in the Notice section that "the products shown herein are not designed for use in medical, life-saving, or life-sustaining applications." While its 150°C TJ max and robust surge rating may appear suitable, MBRS20100CT-Y lacks automotive-specific qualification, PPAP documentation, and extended temperature validation beyond industrial grade (-55°C to +150°C).
What packaging and reel quantity is offered for MBRS20100CT-Y?
MBRS20100CT-Y is supplied in TO-263AB (D2PAK) package on tape-and-reel format, with 800 units per reel, as specified in the Ordering Information section of the Taiwan Semiconductor datasheet Version E2201. The tape meets EIA-481 standards, and the reels are compatible with standard SMT pick-and-place equipment operating at speeds up to 40,000 cph. Moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating pre-bake requirements.
