Product details
Overview
MBRB1090-M3 from Vishay General Semiconductor is a high-voltage Trench MOS Barrier Schottky (TMBS®) rectifier in D2PAK (TO-263AB) package, rated for 90 V repetitive peak reverse voltage, 10 A average forward current at TC = 133 °C, and 150 A non-repetitive surge current. 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 MBRB1090-M3 datasheet, MBRB1090-M3 pinout, MBRB1090-M3 application, or MBRB1090-M3 equivalent, key selection criteria include its 90 V VRRM rating, 2.0 °C/W junction-to-case thermal resistance, MSL Level 1 moisture sensitivity, and compatibility with 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 capability than planar Schottky diodes. Its 150 A IFSM rating supports robust transient handling in SMPS output stages, while dV/dt of 10,000 V/μs ensures stable operation under fast-switching conditions.
The device operates across -65 °C to +150 °C junction temperature range and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Its D2PAK package provides low thermal resistance (RθJC = 2.0 °C/W) and heatsink-compatible mounting via exposed drain tab (Pin 3).
Key Specifications

Use Scenario: Reverse-voltage blocking at main power entry point of PLC I/O modules and motor drives. IC Role / Device Role / Timing Role: Series-connected anode-in protection diode preventing damage from accidental battery reversal. Use Value: 90 V VRRM and 150 A IFSM withstand both sustained reverse bias and momentary surge events without degradation. | Use Scenario: Input-side reverse-polarity and backfeed protection in distributed power architectures with multiple DC rails. IC Role / Device Role / Timing Role: Isolation element preventing cross-rail fault propagation between upstream converters. Use Value: Low RθJC (2.0 °C/W) enables direct thermal coupling to shared heatsink, simplifying thermal management across protection and regulation stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10H100CG | 100 V VRRM, same 10 A IF(AV), VF = 0.72 V @ 10 A, 125 °C; TO-263 package | Suitable where higher reverse margin is required; slightly higher VF increases conduction loss | Select when design requires ≥100 V blocking with minimal footprint change |
| SS10P9 | 90 V VRRM, 10 A IF(AV), VF = 0.82 V @ 10 A, 25 °C; TO-277 package, no heatsink tab | Limited thermal performance (RθJC ≈ 10 °C/W); unsuitable for >5 W continuous dissipation | Acceptable only in low-power, naturally cooled applications where D2PAK mounting is not feasible |
Compared with STPS10H100CG and SS10P9, the MBRB1090-M3 offers superior thermal performance (2.0 °C/W vs. ≥5 °C/W), tighter VF control at elevated temperature, and verified MSL Level 1 process compatibility-making it preferred for high-reliability, high-power-density industrial SMPS designs.

FAQ
What is the maximum junction temperature rating for the MBRB1090-M3?
The MBRB1090-M3 has a maximum junction temperature (TJ max.) of +150 °C, verified per datasheet revision 23-Feb-2024 (Document Number: 87981). This rating enables reliable operation in thermally demanding environments such as enclosed industrial power supplies and motor drive control boards where ambient temperatures exceed 85 °C. The MBRB1090-M3 maintains specified electrical characteristics up to this limit when thermal design accounts for its 2.0 °C/W junction-to-case resistance.
Does the MBRB1090-M3 have a halogen-free and RoHS-compliant construction?
Yes, the MBRB1090-M3 is halogen-free and RoHS-compliant, as confirmed in the official Vishay datasheet (Document Number: 87981, Revision: 23-Feb-2024). The "M3" suffix explicitly denotes compliance with JESD 201 Class 1A whisker testing, halogen-free molding compound, and RoHS Directive 2011/65/EU. This makes the MBRB1090-M3 suitable for export-controlled and environmentally regulated applications including EU-based industrial equipment and medical power systems.
What is the forward voltage drop of the MBRB1090-M3 at 10 A and 125 °C?
The MBRB1090-M3 exhibits a maximum forward voltage (VF) of 0.65 V at IF = 10 A and TC = 125 °C, per the Electrical Characteristics table in Vishay's datasheet (Document Number: 87981). This value reflects actual measured performance under thermal steady-state conditions and is critical for calculating conduction losses in high-efficiency DC/DC converter output stages. The MBRB1090-M3 achieves this low VF through its trench MOS barrier structure, distinguishing it from conventional planar Schottky rectifiers.
Is the MBRB1090-M3 suitable for use in high-frequency switching applications?
Yes, the MBRB1090-M3 is specifically designed for high-frequency operation, with a voltage rate of change (dV/dt) rating of 10,000 V/μs and typical junction capacitance of ~200 pF at 50 V (per Fig. 5 in Document Number: 87981). These parameters enable clean commutation in 100–500 kHz switch-mode topologies such as LLC resonant converters and synchronous buck controllers. The MBRB1090-M3's fast recovery and low stored charge minimize switching losses and EMI generation compared to standard PN-junction rectifiers.
What does the "/4W" suffix mean in the full part number MBRB1090-M3/4W?
The "/4W" suffix in MBRB1090-M3/4W indicates the packaging configuration: 50 devices per tube, with "4W" being Vishay's internal package code for the D2PAK (TO-263AB) tube format. This differs from the "/8W" variant, which ships 800 units per tape-and-reel. Both share identical electrical and thermal specifications. The MBRB1090-M3/4W is intended for prototyping, low-volume production, and automated placement systems compatible with tube-fed feeders.
