Taiwan Semiconductor Corporation MBRF1650

Overview

MBRF1650 from Taiwan Semiconductor is a 16A, 50V Schottky barrier rectifier in ITO-220AC package, featuring 0.75V forward voltage at 16A and 25°C, 150A surge current capability, and AEC-Q101 qualification option. It serves as the output rectifier in high-efficiency DC-DC converters and SMPS where low conduction loss and thermal robustness are critical.

For engineers reviewing the MBRF1650 datasheet, MBRF1650 pinout, MBRF1650 application, or MBRF1650 equivalent, key selection criteria include V_RRM = 50 V, I_F = 16 A continuous, R_θJC = 3 °C/W, TJ max = 150 °C, and ITO-220AC mechanical compatibility with heatsink mounting.

Technical Context

This single-die Schottky rectifier uses a guard ring structure for over-voltage protection and meets UL 94V-0 flammability rating. Its 10,000 V/µs dv/dt rating supports fast-switching topologies, and matte tin-plated leads ensure solderability per J-STD-002.

Thermal performance is defined by 3 °C/W junction-to-case resistance, enabling reliable operation up to 150 °C junction temperature. Reverse leakage is limited to 500 µA at 25 °C and 10 mA at 125 °C under rated 50 V reverse bias.

FAQ

What is the maximum junction temperature rating for the MBRF1650?

The MBRF1650 has a maximum junction temperature (T_J) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures. Derating curves confirm usable current capacity down to 0 A at 150 °C case temperature. The MBRF1650 maintains this specification across all standard and AEC-Q101-qualified versions.

Does the MBRF1650 have AEC-Q101 qualification?

Yes-the MBRF1650 is available in an AEC-Q101-qualified version denoted by the "H" suffix (e.g., MBRF1650H). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). Standard MBRF1650 parts are not automatically qualified; only those ordered with the "H" suffix meet AEC-Q101 requirements. The MBRF1650H is documented in Taiwan Semiconductor's K2105 revision datasheet.

What is the forward voltage of the MBRF1650 at 16 A and 125 °C?

The forward voltage (V_F) of the MBRF1650 is 0.65 V at 16 A and 125 °C, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet (Version K2105). This value reflects reduced voltage drop at elevated temperature due to Schottky physics, supporting stable performance in thermally demanding applications. The MBRF1650 maintains this V_F across its full operating temperature range without degradation.

Is the MBRF1650 pin-compatible with other devices in the MBRF16xx family?

Yes-the entire MBRF16xx series (MBRF1635 through MBRF16150) shares identical ITO-220AC package dimensions, pinout, and terminal configuration. All variants feature Anode, Cathode, and isolated Tab terminals in the same physical layout. This allows direct substitution within the same voltage grade during design iteration or BOM optimization, provided thermal and electrical margins are re-verified for the specific V_RRM and V_F of the selected variant. The MBRF1650 is fully interchangeable with MBRF1645 or MBRF1660 at the board level.

What is the thermal resistance from junction to case (R_θJC) for the MBRF1650?

The junction-to-case thermal resistance (R_θJC) of the MBRF1650 is 3 °C/W, measured under standard test conditions per the Thermal Performance section of the Taiwan Semiconductor datasheet. This value applies to the ITO-220AC package with proper mounting torque (≤0.56 N·m) and clean thermal interface. It enables accurate thermal modeling for heatsink sizing and confirms the MBRF1650 can dissipate up to 48 W continuously when ΔT = 144 °C. The MBRF1650 maintains this R_θJC regardless of voltage rating within the family.
