Taiwan Semiconductor Corporation MBRF10150CT-Y

Overview

MBRF10150CT-Y from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 10 A average forward current, 150 V repetitive peak reverse voltage (VRRM), and 120 A non-repetitive surge current (IFSM), used in high-efficiency DC/DC converters and switching power supplies where low forward voltage drop and fast recovery are critical.

For engineers reviewing the MBRF10150CT-Y datasheet, MBRF10150CT-Y pinout, MBRF10150CT-Y application, or MBRF10150CT-Y equivalent, key selection criteria include verified VRRM = 150 V, VF ≤ 0.98 V at 10 A / 25°C, TJ max = 150°C, RθJC = 3.5°C/W, and ITO-220AB mechanical compatibility with heatsink mounting.

Technical Context

This dual-common-cathode Schottky rectifier integrates two independent die in a single ITO-220AB thermally optimized package, enabling synchronous or interleaved output configurations. Its guard ring structure provides overvoltage protection, and it sustains 5 mA reverse leakage per diode at 125°C under full rated VR.

The device operates across -55°C to +150°C junction temperature range, supports 10,000 V/μs critical dv/dt rating, and delivers stable performance up to 20 kHz square-wave forward current (IFRM = 10 A) without thermal runaway.

FAQ

What is the maximum junction temperature rating for MBRF10150CT-Y?

The MBRF10150CT-Y has a maximum junction temperature (TJ) rating of +150°C, validated across its full operating voltage and current range. This rating enables reliable operation in high-ambient environments such as enclosed server PSUs or industrial motor drives, provided thermal design achieves ≤3.5°C/W junction-to-case resistance and accounts for derating above 100°C ambient.

Does MBRF10150CT-Y support dual independent outputs?

MBRF10150CT-Y features a dual-die common-cathode configuration-not dual independent outputs. Both anodes are electrically isolated, but the cathodes are internally tied together. To implement dual independent outputs, external cathode separation is required; for true dual-output capability, consider discrete single-die Schottky devices instead.

Is MBRF10150CT-Y halogen-free and RoHS compliant?

Yes, MBRF10150CT-Y is certified RoHS compliant and halogen-free per IEC 61249-2-21. The "-Y" suffix explicitly denotes halogen-free molding compound. This makes MBRF10150CT-Y suitable for consumer electronics and medical devices subject to strict material declarations, unlike non-suffixed variants such as MBR10150CT.

What is the reverse leakage current of MBRF10150CT-Y at 150 V and 125°C?

At rated VRRM = 150 V and TJ = 125°C, MBRF10150CT-Y exhibits a maximum reverse leakage current (IR) of 5 mA per diode, measured under 30 ms pulse conditions. This value is confirmed in the Electrical Specifications table and remains stable across the full 150 V reverse bias range at elevated temperature.

Can MBRF10150CT-Y replace MBRF10100CT-Y in a 100 V design?

Yes, MBRF10150CT-Y can safely replace MBRF10100CT-Y in a 100 V design because its 150 V VRRM exceeds the 100 V requirement, and all other parameters-including IF, IFSM, VF, and package-are identical. No layout or thermal redesign is needed, though forward voltage is slightly higher (0.85 V → 0.88 V @ 5 A / 25°C), resulting in negligible conduction loss increase.
