Product details

Overview

MBRS10100H from Taiwan Semiconductor is a 10A, 100V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for low forward voltage drop (0.85 V at 10 A, 25°C), high surge current capability (120 A), and automotive-grade reliability (AEC-Q101 qualified). It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.

For engineers reviewing the MBRS10100H datasheet, MBRS10100H pinout, MBRS10100H application, or MBRS10100H equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 175°C maximum junction temperature, 2°C/W junction-to-case thermal resistance, and compatibility with automated SMT placement.

Technical Context

The MBRS10100H employs a single-die Schottky structure with guard ring overvoltage protection, enabling fast switching and low conduction loss. Its 100 V V_RRM and 0.85 V forward voltage at rated current support efficient operation in 12–48 V automotive and industrial power rails.

Thermally, it delivers 2°C/W R_θJC into the heatsink via the exposed cathode tab of the TO-263AB package, and maintains stable reverse leakage (<5 mA at 125°C) under harsh ambient conditions-critical for under-hood automotive modules.

Key Specifications

V_RRM	100 V - supports 48 V nominal systems with ≥2× safety margin against transients
I_F	10 A continuous - sustains steady-state load in compact DC/DC converter outputs
I_FSM	120 A (8.3 ms) - handles motor startup surges and load dump events
V_F	0.85 V @ 10 A, 25°C - reduces conduction loss to <8.5 W, easing thermal design
T_J max	175°C - enables operation in engine compartment environments without derating
R_θJC	2°C/W - allows direct PCB copper pour heatsinking for passive thermal management
I_R	<100 µA @ 100 V, 25°C - ensures minimal standby power loss in battery-critical systems

FAQ

What is the maximum junction temperature rating for MBRS10100H?

The MBRS10100H has a maximum junction temperature (T_J) of 175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows sustained operation in high-ambient environments such as engine compartments or sealed LED headlamps. Derating curves confirm usable current capacity down to 125°C case temperature, and the device maintains specified electrical performance up to this limit. Thermal design must ensure R_θJC = 2°C/W is achieved via proper PCB copper area under the cathode tab.

Is MBRS10100H suitable for reverse battery protection in 12 V automotive systems?

Yes, MBRS10100H is explicitly validated for reverse battery protection in 12 V automotive systems. Its 100 V V_RRM, 120 A I_FSM, AEC-Q101 qualification, and guard ring structure provide robust protection against polarity reversal events and load dump transients. The device's low forward voltage (0.85 V @ 10 A) minimizes power loss and heat generation during normal operation, making it ideal for inline protection on infotainment, telematics, and lighting modules where space and thermal budget are constrained.

Does MBRS10100H have a defined pinout for TO-263AB (D2PAK)?

Yes, MBRS10100H uses the standard TO-263AB (D2PAK) pinout: Lead 1 is NC (no connect), Lead 2 is Anode, and the exposed metal tab plus Lead 3 form the Cathode. This configuration is confirmed in the mechanical drawings and marking diagram of the Taiwan Semiconductor datasheet (Version A2103). The NC lead must remain unconnected to prevent unintended coupling, and the cathode tab must be soldered to a large copper pour for both electrical return and thermal dissipation.

What is the forward voltage of MBRS10100H at elevated temperature?

The forward voltage of MBRS10100H is 0.71 V at 10 A and 125°C, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value reflects the negative temperature coefficient typical of Schottky diodes and confirms stable conduction behavior under hot operating conditions. At 100°C junction temperature, V_F is approximately 0.75 V. These values are measured under pulsed conditions (PW = 0.3 ms) and are critical for accurate loss calculation in thermal modeling of automotive power stages.

Is MBRS10100H RoHS and halogen-free compliant?

Yes, MBRS10100H is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads satisfy J-STD-002 solderability requirements. These compliance attributes are verified per manufacturing lot and documented in TSC's material declarations, supporting use in environmentally regulated automotive and industrial end equipment.
