Taiwan Semiconductor Corporation MBRF30150CT-Y

Overview

MBRF30150CT-Y from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 30A average forward current, 150V repetitive peak reverse voltage (VRRM), and 200A non-repetitive surge current (IFSM), used in high-efficiency DC/DC converters and industrial SMPS where low forward voltage drop and thermal robustness are critical.

For engineers reviewing the MBRF30150CT-Y datasheet, MBRF30150CT-Y pinout, MBRF30150CT-Y application, or MBRF30150CT-Y equivalent, key selection criteria include VRRM = 150 V, VF = 0.95 V @ 15 A / 25°C, IR = 200 µA @ 150 V / 25°C, RθJC = 4 °C/W, and dual common-cathode configuration in ITO-220AB.

Technical Context

This device integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with common cathode connection. Its low VF and high IFSM support high-frequency switching topologies requiring minimal conduction loss and transient overload resilience.

The junction-to-case thermal resistance of 4 °C/W enables direct heatsink mounting without thermal interface material in many 30A applications, while the guard ring structure provides inherent overvoltage protection up to rated VRRM.

FAQ

What is the maximum junction temperature rating for MBRF30150CT-Y?

The MBRF30150CT-Y has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet E2105. This rating applies across the full operating range and supports reliable operation in enclosed industrial enclosures with ambient temperatures up to +85°C when properly heatsinked. Derating curves confirm usable current capacity down to 10 A at TJ = 150°C, ensuring design margin for thermal transients.

Is MBRF30150CT-Y pin-compatible with other parts in the MBRF30xxCT-Y family?

Yes, all MBRF30xxCT-Y variants-including MBRF3045CT-Y through MBRF30200CT-Y-share identical ITO-220AB package dimensions, pinout (Anode 1 / Anode 2 / Common Cathode Tab), and mounting interface. The only differences are VRRM rating and corresponding VF/IR values; therefore, MBRF30150CT-Y can be substituted within the same footprint when 150 V blocking is required, without PCB changes.

Does MBRF30150CT-Y require thermal interface material when mounted to a heatsink?

MBRF30150CT-Y does not require thermal interface material when mounted directly to an electrically isolated heatsink using the specified 0.56 N·m torque, due to its low RθJC of 4 °C/W and flat, polished metal tab surface. However, if electrical isolation is needed, a mica or ceramic washer with thermal grease may be used-but this increases RθJC by ~1.5–2.0 °C/W and must be factored into thermal design calculations for MBRF30150CT-Y.

What is the reverse leakage current specification for MBRF30150CT-Y at elevated temperature?

At TJ = 125°C and VR = 150 V, the MBRF30150CT-Y exhibits a maximum reverse leakage current (IR) of 10 mA per diode, as specified in the Electrical Specifications table of the TSC E2105 datasheet. This value is critical for standby power budgeting in energy-efficient designs and remains stable across production lots per JESD22-A113 qualification testing.

Can MBRF30150CT-Y be used in synchronous rectification circuits?

No-MBRF30150CT-Y is a passive Schottky rectifier and cannot function as a synchronous rectifier, which requires actively controlled MOSFETs with gate drive timing. However, it serves as a high-performance alternative to synchronous rectifiers in cost-sensitive or EMI-constrained applications where its fixed VF and zero gate-drive overhead provide predictable, jitter-free conduction. For MBRF30150CT-Y, the absence of control signals simplifies layout and eliminates shoot-through risk.
