Product details

Overview

MBRB10100-M3/4W from Vishay General Semiconductor is a high-voltage Trench MOS Barrier Schottky (TMBS®) rectifier in D2PAK (TO-263AB) package, rated for 100 V repetitive peak reverse voltage, 10 A average forward current, and 150 A surge capability. It delivers low 0.65 V forward voltage at 10 A and 125 °C, enabling high-efficiency operation in DC/DC converters and switching power supplies.

For engineers reviewing the MBRB10100-M3/4W datasheet, MBRB10100-M3/4W pinout, MBRB10100-M3/4W application, or MBRB10100-M3/4W equivalent, key selection criteria include its 100 V V_RRM, 2.0 °C/W junction-to-case thermal resistance, MSL Level 1 rating, halogen-free RoHS-compliant construction, and suitability for high-frequency freewheeling and polarity protection circuits.

Technical Context

This TMBS® rectifier uses trench MOS Schottky architecture to achieve lower forward voltage and higher surge robustness than planar Schottky diodes. Its 100 V blocking rating and 150 A I_FSM support high-reliability operation in industrial SMPS and automotive auxiliary power rails.

The device operates across -65 °C to +150 °C junction temperature range with 10 kV/μs dV/dt rating and exhibits <100 μA reverse leakage at 25 °C - critical for low-power standby and energy-sensitive designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - supports input rectification up to 100 V DC or 70 V RMS AC without breakdown
I_F(AV)	10 A at T_C = 133 °C - enables continuous conduction in compact heatsinked layouts
V_F	0.65 V at 10 A, 125 °C - reduces conduction losses by ~30% vs. standard Schottky diodes at same current/temp
I_FSM	150 A (8.3 ms half-sine) - withstands inrush and transient overloads in DC/DC startup and fault conditions
R_θJC	2.0 °C/W - allows direct heatsink mounting for thermal management without additional interface layers
T_J max.	+150 °C - permits operation in high-ambient environments such as under-hood automotive or enclosed industrial enclosures

FAQ

What is the maximum junction temperature rating for the MBRB10100-M3/4W?

The MBRB10100-M3/4W has a maximum junction temperature (T_J) of +150 °C, verified per Vishay's datasheet revision 23-Feb-2024. This rating enables reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations. Derating curves confirm 10 A I_F(AV) is maintained up to T_C = 133 °C, and thermal design must ensure junction temperature remains within this limit under worst-case load and ambient conditions. The MBRB10100-M3/4W achieves this with a low 2.0 °C/W R_θJC when mounted to an adequate heatsink.

Does the MBRB10100-M3/4W have a halogen-free and RoHS-compliant construction?

Yes, the MBRB10100-M3/4W carries the "M3" suffix, indicating halogen-free molding compound, RoHS compliance, and commercial-grade qualification per Vishay documentation. It meets JESD201 Class 1A whisker testing and UL 94 V-0 flammability standards. The matte tin-plated leads are solderable per J-STD-002 and JESD22-B102. These attributes make the MBRB10100-M3/4W suitable for environmentally regulated markets including EU, China, and North America. Full compliance data is documented in Vishay's material categorization notice (doc?99912).

What is the forward voltage drop of the MBRB10100-M3/4W at 10 A and 125 °C?

The MBRB10100-M3/4W exhibits a maximum forward voltage (V_F) of 0.65 V at 10 A and 125 °C, as specified in the Electrical Characteristics table of the official datasheet. This value reflects real-world operating conditions typical in high-power-density converters. At 25 °C, V_F rises to 0.80 V under the same current. The low V_F directly reduces conduction losses - for example, cutting ~1.3 W of dissipation versus a standard 100 V Si diode at 10 A - thereby improving system efficiency and easing thermal management. This performance is enabled by Vishay's TMBS® trench MOS Schottky architecture.

Is the MBRB10100-M3/4W suitable for lead-free reflow soldering processes?

Yes, the MBRB10100-M3/4W is qualified for lead-free reflow per MSL Level 1 (J-STD-020) with a maximum peak temperature of 245 °C. Its construction - including halogen-free epoxy and matte tin-plated terminals - ensures compatibility with standard Pb-free SMT assembly lines. No pre-baking is required prior to reflow. The device's thermal resistance profile (R_θJC = 2.0 °C/W) also supports rapid heat extraction during soldering, minimizing thermal stress. This makes the MBRB10100-M3/4W ideal for high-volume, automated manufacturing of industrial and automotive power modules.

How does the MBRB10100-M3/4W differ from the MBRB1090-M3/4W?

The MBRB10100-M3/4W and MBRB1090-M3/4W share identical package (D2PAK), thermal specs, and construction, but differ in maximum repetitive peak reverse voltage: 100 V vs. 90 V. All other key parameters - I_F(AV) = 10 A, I_FSM = 150 A, V_F = 0.65 V @ 10 A/125 °C, and R_θJC = 2.0 °C/W - are identical. The MBRB10100-M3/4W is selected when 100 V blocking margin is required, such as in 48 V systems with high line transients or 60 V nominal rails. Designers should verify that the 10 V higher V_RRM justifies any potential cost or availability trade-off versus the MBRB1090-M3/4W in their specific application.
