Product details
Overview
MBRB2090CT from Vishay is a center-tap dual Schottky rectifier in D2PAK package, rated for 2 × 10 A average forward current per leg, 90 V reverse voltage, and operation up to 150 °C junction temperature. It delivers low forward voltage drop (0.70 V at 10 A, 125 °C), high-frequency switching capability, and AEC-Q101 qualification - used in automotive DC/DC converters and industrial freewheeling circuits.
For engineers reviewing the MBRB2090CT datasheet, MBRB2090CT pinout, MBRB2090CT application, or MBRB2090CT equivalent, key selection criteria include its 90 V VR, dual-anode/common-cathode topology, thermal resistance of 2.0 °C/W per leg, RoHS- and halogen-free compliance, and suitability for high-reliability reverse battery protection.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling center-tap configuration for full-wave rectification or dual synchronous rectifier control. Its proprietary barrier technology minimizes reverse leakage at elevated temperatures, supporting stable operation up to 150 °C TJ with <6 mA IR at rated VR and 125 °C.
The D2PAK package provides low thermal resistance (RthJC = 2.0 °C/W per leg) and mechanical robustness via high-purity epoxy encapsulation and integrated guard ring. It supports high dV/dt (10,000 V/µs) and handles non-repetitive surge currents up to 850 A (5 µs sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 10 A at TC = 133 °C - defines continuous DC output capability per anode in thermally managed designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR2090CT-1PbF | TO-262 package (through-hole); identical electrical specs but higher RthJA (50 °C/W vs. 2.0 °C/W per leg) | Suitable for prototyping or low-volume through-hole assembly; less efficient thermal transfer than D2PAK | Select when board assembly process requires leaded through-hole mounting or legacy footprint compatibility |
| STPS20H100CG | Single-die dual-anode Schottky in TO-247; 100 V VRRM, 20 A total IF(AV), no AEC-Q101 qualification | Higher voltage margin but lacks automotive qualification; different pinout and thermal profile | Choose for industrial 100 V systems where AEC-Q101 is not required and TO-247 mounting is preferred |
Compared with MBRB2090CT, MBR2090CT-1PbF offers identical electrical performance but requires through-hole layout and delivers inferior thermal performance, while STPS20H100CG trades automotive qualification for higher voltage rating and different mechanical integration - neither is pin-compatible, and both require PCB redesign.

FAQ
What is the maximum junction temperature rating for the MBRB2090CT?
The MBRB2090CT is rated for a maximum junction temperature of 150 °C, validated across its full operating range. This specification enables deployment in under-hood automotive environments and high-ambient industrial settings. The device maintains stable forward voltage and low reverse leakage up to this limit, with thermal design guidance provided in the datasheet including RthJC = 2.0 °C/W per leg. Derating curves in Figure 5 confirm allowable case temperature versus average forward current.
Is the MBRB2090CT suitable for reverse battery protection circuits?
Yes, the MBRB2090CT is explicitly designed for reverse battery protection applications. Its low reverse leakage (6 mA at 125 °C and rated VR) minimizes standby power loss, while the common-cathode dual-anode structure allows simple series-blocking implementation. The AEC-Q101 qualification and 150 °C TJ rating ensure robustness against jump-start transients and sustained high-temperature operation in automotive ECUs - confirmed in the official product description and application notes.
What package type does the MBRB2090CT use, and how is it mounted?
The MBRB2090CT uses the D2PAK (TO-263) surface-mount package with an exposed copper die pad. It is mounted using reflow soldering onto a PCB with thermal vias and copper pour for heatsinking. Mounting torque specifications are 6–12 kgf·cm (5–10 lbf·in) for mechanical anchoring. The package complies with JEDEC MO-211 and features high-purity epoxy encapsulation for moisture resistance - details are documented in Vishay's packaging information document 95032.
Does the MBRB2090CT have AEC-Q101 qualification?
Yes, the MBRB2090CT is AEC-Q101 qualified, as stated in the Vishay datasheet revision 09-Sep-09 (Document Number: 94306). This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock, confirming suitability for automotive under-hood applications. The qualification applies specifically to the MBRB2090CTPbF variant and is not inferred from family-level claims - it is explicitly listed in the FEATURES section.
What is the forward voltage drop of the MBRB2090CT at 10 A and 125 °C?
The forward voltage drop of the MBRB2090CT is 0.70 V at 10 A and 125 °C, per leg, as specified in the ELECTRICAL SPECIFICATIONS table. This value is measured under DC conditions and reflects real-world conduction loss in high-temperature automotive or industrial operation. At 25 °C, VF is 0.80 V at 10 A - confirming the device's low-temperature coefficient and stable performance across its rated junction temperature range.
