Product details
Overview
MBRS2090CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20A average forward current, 90V repetitive peak reverse voltage, and 150A surge current, with 0.85V max forward voltage at 10A/25°C - used in DC/DC converters and reverse battery protection circuits.
For engineers reviewing the MBRS2090CTH datasheet, MBRS2090CTH pinout, MBRS2090CTH application, or MBRS2090CTH equivalent, key selection criteria include VRRM=90V, IF=20A, RθJC=2°C/W, low VF at high temperature, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent die in a single surface-mount D2PAK thermally optimized for high-current switching applications. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.
Designed for operation from −55°C to +150°C junction temperature, it delivers stable performance under high dv/dt stress (10,000 V/μs) and supports automated placement with moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum non-repetitive reverse blocking voltage per diode, defining safe operating range in 12–48V automotive and industrial power rails |
| IF | 20 A - continuous average forward current per diode, enabling high-efficiency power conversion without forced air cooling |
| IFSM | 150 A - peak non-repetitive surge current (8.3ms half-sine), supporting robust start-up and fault transient handling |
| VF @ 10A, 25°C | ≤0.85 V - low forward drop minimizes conduction loss and thermal rise in high-frequency switching topologies |
| RθJC | 2 °C/W - junction-to-case thermal resistance enables direct heatsinking to PCB copper or external metal, critical for thermal management |
| TJ max | +150 °C - maximum junction temperature rating allows reliable operation in under-hood automotive environments |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with common cathode pin (Pin 3), and two anodes (Pins 1 and 2). Molding compound meets UL 94V-0; polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first Schottky diode; connects to high-side switch node or input rail in dual-path freewheeling |
| Pin 2 | Anode 2 | Input terminal for second Schottky diode; enables independent or paralleled current paths in dual-output converters |
| Pin 3 | Common Cathode | Shared output node; electrically ties both diodes' cathodes - simplifies layout and reduces parasitic inductance in return path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and infotainment systems requiring zero defect reliability |
| Guard ring structure | Enhances ruggedness against transient overvoltage events without external snubbers, improving system-level ESD and load-dump immunity |
| Moisture sensitivity level 1 | Eliminates bake-out requirement prior to reflow, reducing manufacturing cost and cycle time in high-volume SMT lines |
| Dual-die configuration | Enables compact dual-channel rectification or redundancy in safety-critical power supplies without doubling footprint |
Applications
| DC/DC Converter | Reverse Battery Protection |
|---|---|
Use Scenario: High-frequency synchronous buck converter in 24V automotive subsystems supplying 3.3V/5V logic rails. IC Role / Device Role / Timing Role: Output rectifier replacing MOSFETs in asynchronous mode or freewheeling path in hybrid configurations. Use Value: Low VF (≤0.85V @ 10A) reduces conduction loss by >30% vs. standard silicon diodes, improving efficiency above 92% at full load. | Use Scenario: Input protection circuit preventing damage during incorrect battery connection in telematics modules. IC Role / Device Role / Timing Role: Series-connected Schottky diode blocking reverse polarity current while minimizing voltage drop across supply path. Use Value: 90V VRRM withstands load dump transients up to ISO 7637-2 Pulse 5a; 0.85V VF limits voltage loss to <1% at 20A nominal current. |
| Car Lighting | Freewheeling Diode |

IC Role / Device Role / Timing Role: Freewheeling path for inductive current decay during MOSFET off-time in boost or buck-boost topology. Use Value: Fast recovery (no minority carrier storage) eliminates reverse recovery spikes, reducing EMI and enabling >500kHz switching frequency. | Use Scenario: Inductive load suppression in solenoid drivers for transmission control units (TCUs). IC Role / Device Role / Timing Role: Clamp diode providing low-impedance path for stored inductor energy during switch turn-off. Use Value: 150A IFSM handles peak currents from 12V solenoids drawing >100A surges, preventing MOSFET avalanche failure. |
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-20CPH09-M3 | Same TO-263AB package, 20A/90V, but higher VF (0.92V typ @ 10A) and no AEC-Q101 qualification | Acceptable for industrial DC/DC where automotive qualification is not required | Choose when cost sensitivity outweighs AEC-Q101 compliance and thermal margin is sufficient |
| ON Semiconductor MBR2090CT | Identical electrical specs and TO-263AB package, but RoHS-compliant only (not halogen-free); lacks JESD201 whisker test certification | Suitable for commercial-grade power supplies with less stringent reliability requirements | Prefer when sourcing flexibility matters more than automotive-grade long-term tin whisker immunity |
Compared with VS-20CPH09-M3 and MBR2090CT, MBRS2090CTH offers verified AEC-Q101 qualification, halogen-free construction, and JESD201 Class 2 whisker resistance - making it the only option qualified for under-hood automotive deployment with zero derating.

FAQ
What is the maximum junction temperature rating for MBRS2090CTH?
The MBRS2090CTH has a maximum junction temperature (TJ) rating of +150°C, validated across its full operating range from −55°C to +150°C. This rating supports reliable operation in under-hood automotive environments and high-power-density industrial converters where ambient temperatures exceed 105°C. The device maintains specified electrical parameters within this range, including VF and IR, as confirmed in the TSC datasheet Version A2103.
Is MBRS2090CTH suitable for reverse battery protection in 24V systems?
Yes, MBRS2090CTH is suitable for reverse battery protection in 24V systems due to its 90V VRRM, which exceeds ISO 7637-2 load dump pulse requirements (up to 60V for 24V systems), and its low 0.85V forward voltage at 10A ensures minimal voltage drop. Its AEC-Q101 qualification and guard ring design further enhance robustness against polarity reversal transients in automotive ECUs and telematics modules.
Does MBRS2090CTH have a common cathode configuration?
Yes, MBRS2090CTH uses a dual-common-cathode configuration: Pins 1 and 2 are independent anodes, and Pin 3 is the shared cathode. This arrangement enables parallel or independent use of both diodes in DC/DC converters, freewheeling paths, or redundant power routing - confirmed in the mechanical outline and marking diagram of the TSC datasheet Version A2103.
What is the thermal resistance from junction to case (RθJC) for MBRS2090CTH?
The junction-to-case thermal resistance (RθJC) for MBRS2090CTH is 2°C/W, as specified in the Thermal Performance section of the TSC datasheet. This value applies to all variants from MBRS2090CTH through MBRS20150CTH and enables effective heat transfer to PCB copper pours or external heatsinks - critical for maintaining TJ ≤150°C at full 20A load in compact automotive modules.
Is MBRS2090CTH halogen-free and RoHS compliant?
Yes, MBRS2090CTH is both RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the TSC datasheet. The molding compound contains no brominated flame retardants or chlorine-based additives, meeting strict environmental and regulatory requirements for automotive and industrial end equipment shipped globally.
