Taiwan Semiconductor Corporation MBRF1560CT

Overview

MBRF1560CT from Taiwan Semiconductor is a 15A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 60V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C; it delivers low forward voltage (0.75V typ. at 7.5A, 25°C) and low reverse leakage (300µA max. at 25°C), enabling high-efficiency power conversion in compact AC/DC adapters.

For engineers reviewing the MBRF1560CT datasheet, MBRF1560CT pinout, MBRF1560CT application, or MBRF1560CT equivalent, key selection criteria include VRRM rating, thermal resistance (RθJC = 3.5°C/W), dual-die configuration, AEC-Q101 qualification availability, and ITO-220AB mechanical compatibility with heatsink mounting.

Technical Context

This dual-common-cathode Schottky rectifier integrates two independent 15A diodes in a single ITO-220AB thermally optimized package, supporting parallel or independent channel operation. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.

The device operates across -55°C to +150°C junction range, exhibits dv/dt capability of 10,000 V/µs, and maintains stable reverse leakage (≤7.5 mA at 125°C, rated VR), making it suitable for high-reliability switching power supplies where thermal management and transient immunity are critical.

FAQ

What is the pin configuration of the MBRF1560CT?

The MBRF1560CT uses a three-terminal ITO-220AB package with Lead 1 as Anode 1, Lead 2 as Anode 2, and the isolated metal tab as the common cathode. This dual-anode, common-cathode arrangement supports independent or paralleled rectification paths without internal shorting. The tab is electrically isolated from the heatsink mounting surface, requiring insulating hardware during installation. MBRF1560CT's pinout is standardized across the MBRF15xxCT family.

Does the MBRF1560CT have AEC-Q101 qualification?

The base MBRF1560CT is not AEC-Q101 qualified; however, the variant MBRF1560CTH (with 'H' suffix) is explicitly qualified per AEC-Q101 Rev D for automotive applications. This includes stress testing for temperature cycling, highly accelerated life testing (HALT), and unbiased high-temperature operating life (UHAST). Always verify the full part number suffix when sourcing for automotive use-MBRF1560CTH is the only version certified for automotive-grade reliability.

What is the maximum allowable case temperature for continuous operation of the MBRF1560CT?

The MBRF1560CT has a maximum junction temperature (TJ) of 150°C and a junction-to-case thermal resistance (RθJC) of 3.5°C/W. For continuous 15A operation, the case temperature must remain ≤115°C to maintain TJ ≤150°C assuming worst-case power dissipation (~1.1W per diode at VF ≈ 0.75V). Derating curves in the datasheet confirm usable current down to 10A at 125°C case temperature. MBRF1560CT's thermal design requires active heatsinking above 5A in enclosed environments.

How does the MBRF1560CT compare to the MBRF1545CT in terms of forward voltage and reverse leakage?

At 7.5A and 25°C, both MBRF1560CT and MBRF1545CT specify VF ≤0.75V (typ), showing no meaningful difference in conduction loss at mid-current. However, reverse leakage differs significantly: MBRF1545CT allows up to 500µA at 25°C, while MBRF1560CT is limited to 300µA max-reflecting tighter process control for higher-voltage variants. At 125°C, MBRF1560CT's IR remains ≤7.5mA, offering better high-temperature stability than lower-VRRM siblings.

Can the MBRF1560CT be used in place of a single-diode Schottky like the SS1560?

MBRF1560CT can replace a single-diode Schottky such as SS1560 only if the circuit uses only one anode and ties the other anode to ground or leaves it unconnected-but this wastes half the device and risks imbalance. Its dual-die structure is intended for true dual-channel use. Using only one anode degrades thermal performance due to asymmetric power distribution and may cause localized hot spots. For single-channel needs, dedicated single-diode parts like VS-15MQ060NTRP are more appropriate than partially utilizing MBRF1560CT.
