Product details
Overview
MBRF25100CT-Y from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 25 A average forward current, 100 V repetitive peak reverse voltage, and 200 A non-repetitive surge current; it delivers low forward voltage (0.85 V at 12.5 A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in compact AC/DC adapters.
For engineers reviewing the MBRF25100CT-Y datasheet, MBRF25100CT-Y pinout, MBRF25100CT-Y application, or MBRF25100CT-Y equivalent, key selection criteria include verified VRRM = 100 V, dual-die configuration with common-cathode topology, thermal resistance RθJC = 1 °C/W, and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
This device integrates two independent Schottky diodes in a single ITO-220AB thermally optimized package with common-cathode connection, supporting high-frequency switching topologies. Its 100 V VRRM, 0.85 V typical forward voltage at 12.5 A/25°C, and 7.5 mA reverse leakage at 100 V/125°C define its suitability for continuous conduction mode operation in SMPS secondary-side rectification.
The guard ring structure provides overvoltage protection, while JESD 201 Class 1A whisker resistance and UL 94V-0 molding compound ensure reliability in industrial-grade power supplies. Junction-to-case thermal resistance of 1 °C/W enables direct heatsink mounting without thermal interface material under moderate load conditions.

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-25CPH10-M3 | Same ITO-220AB package, 25 A/100 V rating, but higher VF = 0.90 V @ 12.5 A/25°C | Marginally lower efficiency in thermally constrained adapters; identical thermal resistance | Select when supply chain diversification is required and 50 mV higher VF is acceptable |
| ON Semiconductor MBR25100CT | Non-Y suffix version; same electrical specs but lacks halogen-free certification per IEC 61249-2-21 | Not suitable for EU medical or automotive-tiered products requiring halogen-free compliance | Choose only for cost-sensitive industrial applications where halogen-free is not mandated |
Compared with VS-25CPH10-M3 and MBR25100CT, the MBRF25100CT-Y offers superior efficiency at elevated temperatures (0.75 V @ 12.5 A/125°C), guaranteed halogen-free compliance, and JESD 201 whisker resistance-critical for high-reliability, long-lifecycle deployments.

FAQ
What is the maximum junction temperature rating for MBRF25100CT-Y?
The MBRF25100CT-Y has a maximum junction temperature (TJ) rating of +150°C, validated across its full operating range from –55°C to +150°C. This specification enables reliable operation in sealed, fanless enclosures where case temperatures may reach 100°C. The device's thermal design leverages RθJC = 1 °C/W to maintain safe junction temperatures under sustained 25 A load conditions when properly heatsinked.
Does MBRF25100CT-Y support common-cathode full-wave rectification?
Yes, MBRF25100CT-Y implements a dual-die common-cathode configuration with one cathode terminal (Lead 2) and two isolated anodes (Tab and Lead 1). This architecture directly supports center-tapped transformer full-wave rectification without external wiring, reducing component count and parasitic inductance compared to discrete dual-diode solutions.
Is MBRF25100CT-Y halogen-free and RoHS compliant?
Yes, MBRF25100CT-Y is certified halogen-free per IEC 61249-2-21 and fully RoHS compliant. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating meeting J-STD-002 solderability standards-ensuring compatibility with lead-free reflow processes and environmental regulations in EU, China, and Korea.
What is the forward voltage of MBRF25100CT-Y at 25 A and 125°C?
The forward voltage of MBRF25100CT-Y is 0.88 V at 25 A and 125°C, measured under pulsed conditions (PW = 0.3 ms). This value reflects stable conduction performance under high-temperature, high-current stress typical of industrial DC/DC converters operating near thermal limits, confirming minimal VF drift across temperature.
Can MBRF25100CT-Y be mounted directly to a heatsink without insulation?
No-MBRF25100CT-Y uses an ITO-220AB package with electrically isolated metal tab, but the tab is internally connected to Anode 1 and must be insulated from the heatsink unless the heatsink is floating or referenced to the same potential. Mounting without an insulating washer risks short-circuiting the first anode to ground or chassis, causing immediate device failure.
