Product details
Overview
MBRF1035CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 10 A average forward current, 35 V repetitive peak reverse voltage, and 120 A non-repetitive surge current; it delivers low forward voltage (0.70 V typ. at 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 MBRF1035CT datasheet, MBRF1035CT pinout, MBRF1035CT application, or MBRF1035CT equivalent, key selection criteria include its 35 V VRRM, dual-common-cathode configuration, thermal resistance of 3.5°C/W, AEC-Q101 qualification option (MBRF1035CTH), and compatibility with high-frequency switching topologies requiring low conduction loss and fast recovery.
Technical Context
The MBRF1035CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its low forward voltage (≤0.80 V max at 10 A, 25°C) minimizes conduction losses, while its 10,000 V/µs critical dv/dt rating supports robust operation in noisy switching environments.
Designed for unidirectional DC output rectification, the device exhibits 100 µA max reverse leakage at 25°C and 15 mA at 125°C under rated 35 V reverse bias, with transient thermal impedance optimized for pulsed load handling per Fig.6 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback or forward converter secondary side. |
| IF | 10 A - Average forward current per diode; supports continuous 10 A DC output in SMPS designs with appropriate heatsinking. |
| IFSM | 120 A - Peak non-repetitive surge current (8.3 ms half-sine); enables reliable startup and overload tolerance in adapter applications. |
| VF | 0.70 V typ. @ 5 A, 25°C - Low conduction loss improves system efficiency and reduces thermal stress vs. standard PN rectifiers. |
| RθJC | 3.5 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink for thermal management in space-constrained designs. |
| TJ max | 150 °C - Maximum junction temperature; supports operation in high-ambient industrial or automotive-adjacent environments. |
| IR | 100 µA max @ 35 V, 25°C - Low reverse leakage preserves standby power budget in energy-efficient power supplies. |
Pinout & Package
Package: ITO-220AB - Thermally optimized 3-lead through-hole package with isolated metal tab (cathode-connected), UL 94V-0 molding compound, matte tin-plated leads, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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-10BQ030 | Single-diode TO-220AB, 10 A, 30 V VRRM, 0.52 V typ. VF @ 10 A - lower VF but 5 V lower blocking rating. | Not dual-anode; requires two devices for full-wave rectification; lacks common-cathode integration. | Select when lowest possible forward drop dominates and dual configuration is unnecessary. |
| ON Semiconductor MBR1035CT | Same 10 A / 35 V rating, ITO-220AB package, but rated for 175°C TJ max and 0.72 V max VF @ 10 A - slightly higher thermal limit, marginally higher VF. | Functionally identical dual-common-cathode topology; pinout and footprint compatible per datasheet mechanical drawings. | Preferred where extended temperature margin is required without changing layout or bill-of-materials. |
Compared with MBRF1035CT, VS-10BQ030 offers lower conduction loss but sacrifices dual-diode integration and voltage margin, while MBR1035CT provides identical functionality with higher junction temperature rating-making it a drop-in alternative only if thermal headroom is critical and sourcing permits.

FAQ
What is the pin configuration of the MBRF1035CT?
The MBRF1035CT uses a 3-terminal ITO-220AB package with Lead 1 and Lead 2 serving as independent anodes, and the metal tab (Lead 3) functioning as the common cathode. This dual-anode/common-cathode arrangement is confirmed in the mechanical drawings and marking diagram of the MBRF1035CT datasheet Version M2105. Polarity is marked on the device body per standard industry convention.
Is the MBRF1035CT suitable for automotive applications?
The MBRF1035CT itself is not AEC-Q101 qualified, but the pin-compatible MBRF1035CTH variant is explicitly listed as AEC-Q101 qualified in the ordering information section. For automotive use, designers must specify the "H" suffix part number; the base MBRF1035CT is intended for industrial and commercial power supplies per TSC's product segmentation.
What is the maximum allowable case temperature for the MBRF1035CT?
The MBRF1035CT has a maximum junction temperature of 150°C and a junction-to-case thermal resistance of 3.5°C/W. While case temperature depends on heatsinking and ambient conditions, sustained case temperatures above 125°C risk exceeding TJ max under full 10 A load. Derating curves in Figure 1 of the MBRF1035CT datasheet define safe operating current versus case temperature.
How does the MBRF1035CT compare to standard PN junction rectifiers in efficiency?
The MBRF1035CT achieves 0.70 V typical forward voltage at 5 A and 25°C-approximately 0.3–0.4 V lower than equivalent 10 A PN rectifiers. This reduction cuts conduction losses by 30–40%, directly improving system efficiency and reducing thermal design burden, especially in high-duty-cycle or high-ambient applications where the MBRF1035CT operates.
Does the MBRF1035CT require a heatsink in all applications?
A heatsink is required for the MBRF1035CT when operating near its 10 A average current rating at elevated ambient temperatures. With RθJC = 3.5°C/W and PD ≈ 7 W at 10 A (using 0.7 V VF), even modest ambient temperatures exceed safe junction limits without thermal management. The datasheet's forward current derating curve (Fig.1) specifies minimum heatsink requirements based on target case temperature.
