Taiwan Semiconductor Corporation MBRF2535CT

Overview

MBRF2535CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 25A average forward current and 35V repetitive peak reverse voltage, with 200A surge capability and 0.82V forward voltage at 25A/25°C. It serves as a high-efficiency output rectifier in compact AC/DC adapters and DC/DC converters where low conduction loss and thermal robustness are critical.

For engineers reviewing the MBRF2535CT datasheet, MBRF2535CT pinout, MBRF2535CT application, or MBRF2535CT equivalent, key selection criteria include its 35V V_RRM, dual-common-cathode configuration, 1°C/W junction-to-case thermal resistance, and AEC-Q101 qualification availability - all directly impacting power stage efficiency, thermal management, and automotive-grade reliability validation.

Technical Context

The MBRF2535CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection, enabling synchronous rectification or dual-output configurations. Its 10,000 V/µs dv/dt rating supports fast-switching topologies, while the guard ring structure provides overvoltage protection without external snubbers.

Thermally, it delivers 8°C/W junction-to-ambient resistance under standard mounting conditions and maintains stable operation up to 150°C junction temperature. The device uses matte tin-plated leads compliant with J-STD-002 solderability and passes JESD201 Class 2 whisker testing.

FAQ

What is the maximum junction temperature rating for the MBRF2535CT?

The MBRF2535CT has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows continuous operation in sealed or high-ambient environments without active cooling, provided thermal design respects the 1°C/W junction-to-case resistance and mounting torque limits. The MBRF2535CT must not exceed this limit during steady-state or transient conditions to ensure reliability and lifetime compliance.

Does the MBRF2535CT have a common cathode or common anode configuration?

The MBRF2535CT uses a dual-common-cathode configuration: both diodes share a single cathode terminal (Lead 2), while their anodes are electrically isolated (Tab and Lead 1). This structure is confirmed in the device marking diagram and mechanical outline drawing. The MBRF2535CT is therefore suited for center-tapped transformer outputs, dual-output flybacks, or parallel anode configurations - not for common-anode applications like OR-ing circuits.

Is the MBRF2535CT RoHS and halogen-free compliant?

Yes, the MBRF2535CT is fully RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet. This compliance applies to the standard version; the AEC-Q101 qualified variant (MBRF2535CTH) maintains identical environmental specifications. The MBRF2535CT meets both regulatory requirements without trade-offs in electrical performance or thermal capability.

What is the forward voltage of the MBRF2535CT at 25A and 125°C?

At 25A forward current and 125°C junction temperature, the MBRF2535CT exhibits a typical forward voltage (V_F) of 0.73V, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value reflects real-world thermal performance under sustained load and confirms lower conduction loss than silicon alternatives even at elevated temperatures. The MBRF2535CT maintains this V_F stability across its full operating temperature range.

Can the MBRF2535CT be used as a direct replacement for the MBR2535CT?

The MBRF2535CT and ON Semiconductor MBR2535CT share identical electrical ratings (25A/35V), pinout, and ITO-220AB package, making them functionally interchangeable in most applications. However, the MBRF2535CT adds halogen-free compliance and guard ring protection - features absent in the MBR2535CT. While the MBRF2535CT can replace the MBR2535CT, the reverse is not recommended where those enhancements are required. Always verify layout compatibility and thermal interface for the specific MBRF2535CT mounting torque (0.56 N·m max).
