Product details
Overview
MBR25100CT-Y from Taiwan Semiconductor is a 25A, 100V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.85V forward voltage at 12.5A/25°C and 0.92V at 25A/25°C, with 200A surge capability and 1°C/W junction-to-case thermal resistance-used in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR25100CT-Y datasheet, MBR25100CT-Y pinout, MBR25100CT-Y application, or MBR25100CT-Y equivalent, key selection criteria include repetitive peak reverse voltage (100V), forward voltage consistency across temperature, dual-diode configuration for center-tapped rectification, and RoHS/halogen-free compliance for regulated power systems.
Technical Context
This device implements a dual common-cathode Schottky diode structure enabling synchronous or center-tapped full-wave rectification. Its low forward voltage minimizes conduction loss, while the guard ring design provides overvoltage protection against transient spikes up to 10,000 V/μs dv/dt rating.
The TO-220AB package supports direct heatsink mounting with 0.56 N·m max torque and achieves 1°C/W thermal resistance from junction to case-critical for maintaining 150°C maximum junction temperature under sustained 25A DC load in compact power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in 48V–72V bus applications |
| IF | 25 A - Continuous average forward current per diode; enables single-device solution for 50W–100W output stages |
| VF @ 25A/25°C | 0.92 V - Measured forward drop at full rated current; determines conduction loss of ~23W per diode at 25A |
| IFSM | 200 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients without failure |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct thermal interface to heatsink for stable 150°C TJ operation |
| IR @ 100V/25°C | 100 µA - Reverse leakage per diode; ensures minimal standby power loss in offline adapters |
| TJ max | 150 °C - Maximum allowable junction temperature; supports operation in sealed industrial enclosures |
Pinout & Package
Package: TO-220AB, 3-terminal molded plastic case with matte tin-plated leads, UL 94V-0 rated compound, polarity marked on body.

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-25CPH100 | Same 100V VRRM, 25A IF, TO-247 package; higher VF (0.97V @ 25A) and RθJC (0.9°C/W) | Larger footprint; better thermal performance but requires PCB rework | Preferred when higher surge margin or legacy TO-247 layout exists |
| ON Semiconductor MBR25100CT | Identical electrical specs and TO-220AB package; lacks "-Y" suffix denoting halogen-free and RoHS-compliant molding compound | Not suitable for EU medical or telecom deployments requiring halogen-free certification | Select MBR25100CT-Y when IEC 61249-2-21 compliance is mandatory |
Compared with VS-25CPH100 and MBR25100CT, the MBR25100CT-Y delivers identical rectification performance in a halogen-free TO-220AB package with lower forward voltage-making it optimal for space-constrained, regulated industrial and telecom power designs where material compliance and thermal efficiency are jointly critical.

FAQ
What is the maximum junction temperature rating for MBR25100CT-Y?
The MBR25100CT-Y has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet revision B2104. This rating allows continuous operation at full 25A current under proper heatsinking and ambient conditions up to 70°C. Derating curves in Figure 1 confirm usable current down to 125°C case temperature.
Does MBR25100CT-Y support center-tapped transformer rectification?
Yes, the MBR25100CT-Y supports center-tapped transformer rectification due to its dual common-cathode Schottky diode configuration. Pins 1 and 3 serve as independent anodes, while Pin 2 is the shared cathode-enabling balanced dual-leg conduction without external interconnects. This topology is explicitly validated in TSC's application guidance for SMPS and DC-DC converters.
What is the forward voltage of MBR25100CT-Y at 25A and 125°C?
The forward voltage of MBR25100CT-Y is 0.88 V at 25A and 125°C, as specified in the Electrical Specifications table (page 2, revision B2104). This value reflects reduced voltage drop at elevated temperature due to Schottky physics and is critical for thermal stability analysis in high-ambient applications such as enclosed industrial power modules.
Is MBR25100CT-Y halogen-free and RoHS compliant?
Yes, MBR25100CT-Y is both RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the FEATURES section of the official Taiwan Semiconductor datasheet. The "-Y" suffix explicitly denotes halogen-free molding compound, distinguishing it from non-suffixed variants like MBR25100CT that lack this material certification.
What is the reverse leakage current of MBR25100CT-Y at rated voltage and 125°C?
The reverse leakage current (IR) of MBR25100CT-Y is 7.5 mA at 100V reverse voltage and 125°C, per the Electrical Specifications table. This value is measured under pulse conditions (PW = 30 ms) and represents worst-case leakage in high-temperature operation-essential for calculating standby losses in offline adapters and telecom rectifiers.
