Product details
Overview
MBRF2535CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package, rated for 25A average forward current, 35V repetitive peak reverse voltage, and 200A non-repetitive surge current; it delivers low forward voltage (0.82V at 25A, 25°C) and high thermal efficiency (RθJC = 1°C/W), enabling compact, high-efficiency power conversion in automotive-grade DC/DC converters.
For engineers reviewing the MBRF2535CTH datasheet, MBRF2535CTH pinout, MBRF2535CTH application, or MBRF2535CTH equivalent, key selection considerations include its AEC-Q101 qualification, dual-die configuration with common-cathode topology, 150°C maximum junction temperature, UL recognition (E-326243), and 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 matte tin-plated leads and UL 94V-0 molding compound. Its guard ring structure provides overvoltage protection, while JESD 201 Class 2 whisker resistance ensures long-term solder joint reliability under thermal cycling.
The MBRF2535CTH operates across -55°C to +150°C junction temperature range and supports high-frequency switching with 10,000 V/µs critical dv/dt rating. Its low RθJA (8°C/W) and RθJC (1°C/W) enable high-power dissipation without external heatsink in many automotive and industrial applications.
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-25CPQ035 | Same 35 V VRRM, 25 A IF, but TO-247AC package; higher RθJC (1.5°C/W); no AEC-Q101 qualification | Targeted at commercial/industrial SMPS, not automotive qualified designs | Select when cost sensitivity outweighs automotive qualification and thermal performance is less constrained |
| ON Semiconductor MBR2535CT | Identical electrical specs and ITO-220AB package, but lacks AEC-Q101 qualification and UL recognition | Suitable for non-automotive industrial or consumer applications where qualification is not mandated | Choose for cost-sensitive non-automotive designs requiring same footprint and thermal profile |
Compared with VS-25CPQ035 and MBR2535CT, the MBRF2535CTH uniquely combines AEC-Q101 qualification, UL recognition, and best-in-class RθJC, making it the only option qualified for under-hood automotive use without thermal or safety compromises.

FAQ
What does the "H" suffix in MBRF2535CTH signify?
The "H" suffix in MBRF2535CTH indicates full AEC-Q101 qualification, including stress testing for temperature cycling, humidity bias, and mechanical shock per automotive reliability standards. This distinguishes it from the non-H version (MBRF2535CT), which lacks formal automotive qualification. The MBRF2535CTH also carries UL Recognition (E-326243) and halogen-free compliance - all verified per Taiwan Semiconductor's L2105 datasheet revision.
Is MBRF2535CTH a common-cathode or common-anode device?
The MBRF2535CTH is a common-cathode dual Schottky rectifier: Lead 2 is the shared cathode, while the insulated tab and Lead 1 serve as the two independent anodes. This configuration is confirmed in the device marking diagram and absolute maximum ratings table, and is essential for center-tapped transformer rectification and dual-output DC/DC designs. The ITO-220AB package physically isolates the tab to support this topology.
What is the maximum recommended mounting torque for MBRF2535CTH?
The maximum mounting torque for MBRF2535CTH is 0.56 N·m, as specified in the Mechanical Data section of the official datasheet. Exceeding this value risks cracking the epoxy molding compound or damaging internal wire bonds. Proper torque control ensures optimal thermal contact between the insulated tab and heatsink while maintaining mechanical integrity and long-term reliability in vibration-prone environments like automotive under-hood applications.
Does MBRF2535CTH require a heatsink in typical 25 A operation?
Yes - although MBRF2535CTH has excellent thermal resistance (RθJC = 1°C/W), sustained 25 A operation at ambient temperatures above 60°C requires a heatsink to maintain TJ ≤ 150°C. Without heatsinking, power dissipation (≈20.5 W at VF = 0.82 V) would exceed safe limits. The ITO-220AB tab is designed for direct heatsink mounting with electrically insulating thermal pads or mica washers when needed.
How does MBRF2535CTH compare to MBRF2545CT in terms of forward voltage?
At 25 A and 25°C, both MBRF2535CTH and MBRF2545CT exhibit identical typical forward voltage (VF = 0.82 V), as confirmed in the Electrical Specifications table. Their VF divergence begins at higher voltages (e.g., MBRF2550CT and above show higher VF due to wider bandgap trade-offs). Thus, for 35 V and 45 V variants, VF performance is equivalent - making MBRF2535CTH optimal where lower VRRM suffices and lowest conduction loss is prioritized.
