Taiwan Semiconductor Corporation MBRF16150H

Overview

MBRF16150H from Taiwan Semiconductor is a 16A, 150V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.95V forward voltage at 16A/25°C, 5mA reverse leakage at 150V/125°C, and 150A surge current capability. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the MBRF16150H datasheet, MBRF16150H pinout, MBRF16150H application, or MBRF16150H equivalent, key selection criteria include its 150V VRRM rating, AEC-Q101 qualification, low VF at high junction temperature, guard ring–enhanced over-voltage robustness, and ITO-220AC thermal performance (RθJC = 3°C/W).

Technical Context

This single-die Schottky rectifier uses a planar guard ring structure to suppress edge breakdown and sustain repetitive 150V reverse voltage. Its low forward voltage drop and high surge current rating (150A, 8.3ms half-sine) enable efficient power conversion in high-frequency switching topologies.

Thermally optimized for bolt-down mounting, the ITO-220AC package delivers 3°C/W junction-to-case resistance and supports continuous operation up to +150°C junction temperature, with UL 94V-0 molding compound and matte tin-plated leads compliant with J-STD-002 solderability.

FAQ

What is the maximum junction temperature rating for MBRF16150H?

The MBRF16150H has a maximum junction temperature (TJ max) of +150°C, verified per JEDEC JESD22-A108. This rating allows continuous operation in high-ambient environments such as under-hood automotive locations or enclosed industrial enclosures. Derating curves confirm usable current capacity down to 0A at 150°C case temperature, and the device must be mounted with ≤0.56 N·m torque to maintain thermal integrity. MBRF16150H thermal performance is validated with RθJC = 3°C/W.

Is MBRF16150H pin-compatible with standard TO-220AB rectifiers?

No, MBRF16150H uses the ITO-220AC package, which features an electrically isolated metal tab-unlike TO-220AB's conductive tab. While outline dimensions and lead spacing match TO-220AB, the isolation requires no insulating hardware but prohibits direct electrical connection of the tab to heatsink ground. MBRF16150H pinout remains Anode–Cathode–Isolated Tab, and PCB footprints must accommodate isolation clearance. MBRF16150H cannot be substituted into TO-220AB layouts without verification of creepage/clearance.

Does MBRF16150H meet automotive qualification standards?

Yes, MBRF16150H is explicitly AEC-Q101 qualified per the manufacturer's documentation and ordering code suffix "H". It undergoes stress testing including temperature cycling, humidity bias, mechanical shock, and high-temperature reverse bias per AEC-Q101 Rev D. Certification applies to the full production lot, not just sample units. MBRF16150H is approved for use in automotive power supplies, body control modules, and ADAS subsystems where reliability under thermal and vibration stress is mandatory.

What is the forward voltage specification of MBRF16150H at elevated temperature?

At 16A and TJ = 125°C, the MBRF16150H exhibits a typical forward voltage (VF) of 0.92V, with no maximum specified-only a typical value per datasheet Table "ELECTRICAL SPECIFICATIONS". This represents a 0.03V reduction from its 25°C VF of 0.95V, confirming negative temperature coefficient behavior typical of Schottky diodes. The value is measured under pulse conditions (PW = 0.3ms) to avoid self-heating artifacts. MBRF16150H maintains this low VF drift across its full operating range.

How does the guard ring in MBRF16150H improve reliability?

The guard ring in MBRF16150H is a diffused p-type region surrounding the active Schottky junction, designed to equalize electric field distribution at the silicon edge and suppress premature avalanche breakdown. This structure increases the device's critical dv/dt rating to 10,000 V/µs and improves immunity to line transients and switching noise in SMPS applications. It directly contributes to MBRF16150H's ability to withstand repetitive 150V reverse voltage without degradation, extending service life in high-noise industrial and automotive systems.
