Product details

Overview

MBRF7100H from Taiwan Semiconductor is a 7.5A, 100V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.92V forward voltage at 7.5A/25°C, 150A surge capability, and guard ring over-voltage protection-used in automotive-grade DC-DC converters and SMPS secondary-side rectification.

For engineers reviewing the MBRF7100H datasheet, MBRF7100H pinout, MBRF7100H application, or MBRF7100H equivalent, key selection criteria include its 100V V_RRM, AEC-Q101 qualification, low VF at high temperature, ITO-220AC thermal performance (R_θJC = 7°C/W), and 5mA reverse leakage at 125°C under rated VR.

Technical Context

This single-die Schottky rectifier operates with zero recovery time and minimal switching loss, enabling high-frequency operation in isolated and non-isolated topologies. Its guard ring structure enhances ruggedness against transient over-voltage events common in automotive 12V/24V systems.

The device sustains 150A non-repetitive surge current (8.3ms half-sine) and maintains stable conduction up to 150°C junction temperature, with thermal resistance optimized for bolt-down heatsink mounting per ITO-220AC mechanical spec.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-75SQ045N	45V V_RRM, 75A I_FSM, TO-220AC package, VF = 0.52V @ 7.5A/25°C	Limited to ≤45V systems; unsuitable for 100V-rated outputs or automotive load-dump scenarios.	Select when lower VF and higher surge margin are critical in ≤45V applications with space-constrained layouts.
ON Semiconductor MBR7100CT	100V V_RRM, dual common-cathode die in TO-220AB, VF = 0.89V @ 7.5A/25°C, no AEC-Q101	Dual configuration enables center-tapped rectification; lacks automotive qualification and has higher thermal resistance (R_θJC = 9°C/W).	Choose for cost-sensitive dual-output SMPS where AEC-Q101 is not mandated and layout supports dual-anode routing.

Compared with VS-75SQ045N and MBR7100CT, MBRF7100H uniquely combines 100V rating, AEC-Q101 qualification, and 7°C/W thermal resistance in a single-die ITO-220AC package-making it optimal for thermally constrained, automotive-compliant 7.5A rectification where reliability under transient stress is mandatory.

FAQ

What is the maximum junction temperature rating for MBRF7100H?

The MBRF7100H has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as engine bays or sealed industrial enclosures. Derating begins above 100°C case temperature, and thermal design must ensure R_θJA remains within limits to prevent exceeding 150°C under worst-case load and ambient conditions. The MBRF7100H's 7°C/W R_θJC supports this rating when mounted to an adequately sized heatsink.

Is MBRF7100H pin-compatible with standard TO-220AC rectifiers?

Yes, MBRF7100H uses the ITO-220AC package, which shares identical mechanical footprint and lead spacing with TO-220AC but features electrically isolated tab. This allows direct PCB footprint reuse in existing TO-220AC layouts, though thermal pad isolation must be verified. The MBRF7100H pinout (Anode–Cathode–Isolated Tab) matches industry-standard single-diode TO-220AC devices, enabling drop-in replacement where isolation and AEC-Q101 compliance are required.

Does MBRF7100H meet halogen-free and RoHS requirements?

Yes, MBRF7100H is halogen-free per IEC 61249-2-21 and RoHS compliant, as confirmed in the official Taiwan Semiconductor datasheet revision K2105. The molding compound contains no brominated flame retardants or chlorine-based additives, and all homogeneous materials pass EU Directive 2011/65/EU limits for Pb, Cd, Hg, Cr(VI), PBB, and PBDE. This makes MBRF7100H suitable for green manufacturing and export to regulated markets.

What is the forward voltage of MBRF7100H at elevated temperature?

At 7.5A and 125°C junction temperature, the MBRF7100H exhibits a typical forward voltage (V_F) of 0.82V, per electrical specifications table. This value is critical for thermal stability analysis, as lower V_F at high temperature reduces self-heating and avoids thermal runaway. The MBRF7100H's V_F increases only ~0.1V from 25°C to 125°C, demonstrating superior temperature coefficient versus standard silicon rectifiers.

How does the guard ring in MBRF7100H improve reliability?

The guard ring in MBRF7100H is a diffused p-type region surrounding the active Schottky junction, designed to suppress edge breakdown under high dv/dt or transient over-voltage. It increases the effective breakdown voltage margin beyond the rated 100V V_RRM, particularly during load dump (ISO 7637-2 Pulse 5a) or inductive switching events. This feature directly improves long-term reliability in automotive and industrial power systems where voltage spikes exceed steady-state ratings.
