Product details

Overview

MBR7100 from Taiwan Semiconductor is a 7.5A, 100V Schottky barrier rectifier in TO-220AC package, designed for high-efficiency DC/DC conversion and SMPS output stages. It delivers 0.92V forward voltage at 7.5A and 25°C, supports 150A non-repetitive surge current, operates up to 150°C junction temperature, and features guard ring overvoltage protection.

For engineers reviewing the MBR7100 datasheet, MBR7100 pinout, MBR7100 application, or MBR7100 equivalent, key selection criteria include its 100V V_RRM, low thermal resistance (R_θJC = 5°C/W), AEC-Q101 qualification option (MBR7100H), and compatibility with high-frequency switching topologies requiring minimal conduction loss.

Technical Context

The MBR7100 uses a single-die Schottky structure optimized for low forward voltage and fast recovery, enabling high efficiency in continuous conduction mode (CCM) and critical conduction mode (CrCM) power supplies. Its 10,000 V/µs dV/dt rating ensures robustness against voltage transients in hard-switched converters.

Thermally, it leverages the TO-220AC case for direct heatsink mounting, with R_θJA = 15°C/W (free air) and R_θJC = 5°C/W - enabling reliable 7.5A operation at T_C ≤ 100°C without forced airflow.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum reverse blocking voltage; defines usable input/output voltage range in buck, flyback, and LLC secondary-side rectification
I_F	7.5 A - Continuous forward current rating; sets minimum trace width and heatsink sizing for steady-state operation
V_F @ 7.5A, 25°C	0.92 V - Low conduction loss enables >94% efficiency in 12V-output SMPS at full load
I_FSM	150 A - Peak surge capability handles inrush and short-circuit events without failure
T_J max	150 °C - Enables operation in automotive under-hood and industrial ambient environments up to 105°C with margin
R_θJC	5 °C/W - Allows direct thermal interface to heatsink; 10W dissipation raises case temp only 50°C above heatsink
I_R @ 100V, 125°C	5 mA - Low leakage preserves efficiency in high-temp DC/DC converters and battery-isolated systems

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-75SQ030	30V V_RRM, 75A I_FSM, 0.42V V_F @ 7.5A - lower voltage, higher surge, lower V_F	Not suitable for 100V systems; limited to ≤48V outputs	Select only for low-voltage, ultra-high-efficiency designs where V_RRM margin is not required
ON Semiconductor MBR7100G	Same 100V V_RRM, 7.5A I_F, but TO-220AB package (non-isolated tab); 0.95V V_F @ 7.5A	Requires insulating hardware for heatsink mounting; slightly higher conduction loss	Use when cost sensitivity outweighs thermal performance and isolation needs

Compared with VS-75SQ030 and MBR7100G, the MBR7100 uniquely balances 100V blocking, 0.92V conduction loss, isolated TO-220AC packaging, and AEC-Q101 availability - making it optimal for mid-voltage industrial and automotive DC/DC where reliability and thermal management are co-prioritized.

FAQ

What is the maximum junction temperature rating for the MBR7100?

The MBR7100 has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version K2103). This allows the MBR7100 to operate reliably in high-ambient environments such as automotive engine bays or enclosed industrial power supplies when properly heatsinked. Derating curves confirm 7.5A continuous current is sustainable up to 100°C case temperature.

Is the MBR7100 pin-compatible with other TO-220AC Schottky rectifiers?

Yes - the MBR7100 uses standard TO-220AC mechanical dimensions and 3-pin anode/cathode/tab configuration, matching industry-standard footprints including ON Semiconductor's MBR7100G and Diodes Inc.'s SB7100. However, the MBR7100 tab is electrically isolated, unlike TO-220AB variants, so insulation requirements must be re-verified in existing layouts before substitution.

Does the MBR7100 have AEC-Q101 qualification?

The base MBR7100 is not AEC-Q101 qualified, but the MBR7100H variant - identical electrically and mechanically - is fully AEC-Q101 qualified per Version K2103 documentation. The "H" suffix denotes automotive-grade stress testing including temperature cycling, HTRB, and ESD. Customers requiring automotive use must specify MBR7100H, not MBR7100.

What is the typical forward voltage of the MBR7100 at elevated temperature?

At 7.5A and 125°C junction temperature, the MBR7100 exhibits a typical forward voltage of 0.82V, per Electrical Specifications table in the Taiwan Semiconductor datasheet. This represents a 10.9% increase from its 0.92V value at 25°C - confirming stable, predictable conduction behavior across its full operating range without thermal runaway.

How does the guard ring feature improve reliability in the MBR7100?

The guard ring in the MBR7100 mitigates edge electric field crowding at the silicon periphery, preventing premature avalanche breakdown under repetitive reverse-bias transients. This extends lifetime in SMPS applications with high dV/dt waveforms and improves consistency in production lots - a key factor validated in AEC-Q101 testing for the MBR7100H variant.
