Product details

Overview

MBR7100H from Taiwan Semiconductor is a 7.5A, 100V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.92V forward voltage at 7.5A/25°C, 150A surge capability, and guard ring overvoltage protection-used in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the MBR7100H datasheet, MBR7100H pinout, MBR7100H application, or MBR7100H equivalent, key selection criteria include peak reverse voltage (100V), thermal resistance (R_θJC = 5°C/W), junction temperature range (–55°C to +150°C), and AEC-Q101 qualification status for automotive reliability validation.

Technical Context

This single-die Schottky rectifier uses platinum-silicide metallization for low VF and fast switching with no minority-carrier storage delay. Its guard ring structure enhances ruggedness against transient overvoltage events common in automotive load-dump conditions.

Designed for high-efficiency power conversion, it operates with 5mA max reverse leakage at 125°C and supports 10,000 V/µs dV/dt-enabling stable performance in high-frequency switching topologies up to 20kHz square-wave rated current.

R_θJC	5 °C/W - Junction-to-case thermal resistance; enables direct mounting to heatsink with minimal thermal interface resistance
T_J max	+150 °C - Maximum junction temperature; supports operation in under-hood automotive environments
AEC-Q101	Qualified - Meets stress test requirements for automotive discrete semiconductors including temperature cycling and HTRB

Pinout & Package

TO-220AC package: 3-terminal through-hole device with anode (pin 1), cathode (pin 2), and electrically isolated metal tab (pin 3, connected to cathode). Mounting torque ≤0.56 N·m; matte tin-plated leads compliant with J-STD-002 solderability.

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-MBR7100CT	TO-220AB dual common-cathode; 0.89V V_F @ 7.5A but only 100V V_RRM; no AEC-Q101 listing	Requires dual-diode layout; unsuitable for automotive qualification-critical designs	Select when dual-output or lower V_F is prioritized over automotive compliance
ON Semiconductor MBR7100	Same 100V/7.5A rating and TO-220AC package but lacks AEC-Q101 qualification and has 0.95V V_F @ 7.5A/25°C	Acceptable for industrial non-automotive use where qualification is not required	Select for cost-sensitive industrial applications without automotive reliability mandates

Compared with MBR7100H, VS-MBR7100CT offers slightly lower forward voltage but requires PCB redesign for dual-diode footprint and lacks automotive qualification; MBR7100 matches mechanical form but trades off AEC-Q101 compliance and higher V_F, making MBR7100H the sole choice for qualified automotive power stages.

FAQ

What is the maximum junction temperature rating for MBR7100H?

The MBR7100H has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm usable current capacity down to 0A at 150°C case temperature. Thermal design must maintain T_J ≤150°C under worst-case power dissipation and ambient conditions.

Is MBR7100H pin-compatible with standard TO-220AC rectifiers?

Yes, MBR7100H uses the industry-standard TO-220AC package with identical pin 1 (anode), pin 2 (cathode), and metal tab (cathode-connected) configuration. It mates with standard TO-220AC sockets and heatsinks. Mechanical drawings confirm lead pitch, body dimensions, and mounting hole alignment match JEDEC TO-220AC specifications-no PCB layout changes are needed when replacing legacy TO-220AC Schottky or fast recovery diodes.

Does MBR7100H meet automotive qualification standards?

Yes, MBR7100H is explicitly AEC-Q101 qualified per the Taiwan Semiconductor ordering code suffix "H", confirmed in the official datasheet Version K2103. Qualification includes temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). This makes MBR7100H suitable for automotive powertrain, chassis, and ADAS applications where component-level reliability validation is mandatory.

What is the forward voltage drop of MBR7100H at full rated current?

The MBR7100H exhibits a typical forward voltage (V_F) of 0.92V at 7.5A and 25°C junction temperature, as specified in the Electrical Specifications table. At elevated temperature (125°C), V_F drops to 0.82V due to negative temperature coefficient of Schottky diodes-this improves thermal stability in high-power continuous operation. Measurements are based on 0.3ms pulse testing per datasheet note.

How does the guard ring feature benefit MBR7100H in real-world applications?

The guard ring in MBR7100H prevents premature edge breakdown during voltage transients, such as ISO 7637-2 Pulse 5a load dump events in automotive systems. It extends the effective depletion region at the silicon periphery, raising the practical avalanche threshold beyond the nominal 100V V_RRM. This structural enhancement improves long-term reliability in noisy power rails without requiring external TVS clamping-reducing BOM count and board area in safety-critical DC-DC stages.
