Product details
Overview
MBRF3080CT-Y from Taiwan Semiconductor is a 30A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 80V repetitive peak reverse voltage (VRRM), 200A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.85V typ. at 15A/25°C) and supports high-efficiency switching mode power supplies.
For engineers reviewing the MBRF3080CT-Y datasheet, MBRF3080CT-Y pinout, MBRF3080CT-Y application, or MBRF3080CT-Y equivalent, key selection criteria include its 80V VRRM rating, dual-common-cathode configuration, thermal resistance (RθJC = 4°C/W), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This dual-die Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling full-wave rectification without external diode pairing. Its guard ring structure provides overvoltage protection, and the ITO-220AB package supports direct heatsink mounting with 0.56 N·m max torque.
Designed for high-frequency operation, it exhibits dv/dt capability of 10,000 V/µs and low junction capacitance - critical for minimizing switching losses in DC-DC converters operating above 20 kHz. Reverse leakage remains ≤10 mA at 125°C and rated VR.
Key Specifications

IC Role / Device Role / Timing Role: Primary output rectifier in phase-shifted full-bridge topology; withstands 200A surge during hot-insertion events. Use Value: IFSM = 200A enables robust N+1 failover without fuse coordination issues, extending mean time between failures (MTBF). |
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-30CPH08-M3 | Same ITO-220AB package, 30A/80V rating, but single-die construction; VF = 0.82V max @ 15A/25°C; RθJC = 3.5°C/W | Lacks dual-common-cathode configuration; requires two devices for full-wave rectification | Select when discrete layout flexibility or lower thermal resistance is prioritized over integration |
| ON Semiconductor MBR30H80CT | ITO-220AB, 30A/80V, dual-common-cathode, but VF = 0.87V max @ 15A/25°C; TJ max = 175°C; halogen-free not specified | Higher max junction temperature enables higher ambient operation, but lacks halogen-free certification | Select for extended temperature range needs where RoHS/halogen-free compliance is secondary |
Compared with VS-30CPH08-M3 and MBR30H80CT, the MBRF3080CT-Y uniquely combines dual-common-cathode integration, halogen-free compliance, and validated 125°C reverse leakage performance - making it optimal for space-constrained, regulated, and thermally demanding SMPS designs.

FAQ
What is the marking code for MBRF3080CT-Y?
The marking code printed on the device body is "MBRF3080CT". The "-Y" suffix denotes halogen-free and RoHS-compliant packaging per IEC 61249-2-21. Date code (YWW format) and factory code (F) appear adjacent to the part number on the ITO-220AB package surface.
Does MBRF3080CT-Y support full-wave rectification without external components?
Yes. MBRF3080CT-Y integrates two Schottky diodes in a common-cathode configuration, allowing direct full-wave rectification from a center-tapped transformer or dual-phase input. No external diode pairing or additional interconnects are needed - simplifying layout and reducing parasitic inductance in high-frequency SMPS designs.
What is the maximum recommended mounting torque for MBRF3080CT-Y?
The maximum mounting torque for MBRF3080CT-Y is 0.56 N·m. Exceeding this value risks cracking the epoxy molding compound or damaging internal wire bonds. Use a calibrated torque screwdriver and ensure flat, clean heatsink surfaces to maintain optimal thermal contact and mechanical reliability over thermal cycling.
How does MBRF3080CT-Y perform at elevated junction temperatures?
At 125°C junction temperature, MBRF3080CT-Y maintains VF ≤0.82V at 30A and reverse leakage ≤10 µA at rated 80V. This stable high-temperature behavior enables reliable operation in enclosed, fanless systems - verified via JEDEC JESD22-A108 thermal cycling and JESD22-A113 HTOL testing per TSC qualification standards.
Is MBRF3080CT-Y compatible with lead-free reflow soldering processes?
Yes. MBRF3080CT-Y features matte tin-plated leads qualified to J-STD-002 for solderability, and its UL 94V-0 epoxy compound withstands peak reflow temperatures up to 260°C for 10 seconds. The device is rated for standard SnPb and lead-free solder profiles, including IPC/JEDEC J-STD-020D moisture sensitivity level 1.
