Product details
Overview
VS-MBRB2045CTTRLP from Vishay Semiconductors is a high-performance dual common-cathode Schottky rectifier in D2PAK (TO-263AB) package, rated for 2 × 10 A average forward current per leg, 45 V reverse voltage, and 0.57 V forward voltage at 10 A and 125 °C - optimized for high-efficiency DC/DC converters and reverse battery protection in automotive power systems.
For engineers reviewing the VS-MBRB2045CTTRLP datasheet, VS-MBRB2045CTTRLP pinout, VS-MBRB2045CTTRLP application, or VS-MBRB2045CTTRLP equivalent, key selection criteria include its 150 °C junction rating, low 0.72 V VF at 20 A (25 °C), 8 mJ non-repetitive avalanche energy, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This device integrates two independent Schottky die sharing a common cathode terminal, enabling center-tap configuration without external wiring. Its proprietary barrier technology minimizes reverse leakage up to 150 °C, while low thermal resistance (RthJC = 2.0 °C/W per leg) supports high-power density designs.
Designed for high-frequency switching (dV/dt = 10,000 V/μs), it delivers fast recovery with negligible stored charge and exhibits 600 pF junction capacitance at 5 V - critical for minimizing switching losses in synchronous rectification and freewheeling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 45 V - maximum DC reverse voltage; sets upper limit for blocking capability in 12 V/24 V automotive battery systems. |
| IF(AV) | 2 × 10 A - average forward current per leg; enables 20 A total output in dual-leg parallel operation with shared cathode. |
| VF | 0.57 V at 10 A, 125 °C - low conduction loss ensures >95% efficiency in 5–12 V output buck converters at full load. |
| IRM | 15 mA at 125 °C - ultra-low reverse leakage preserves system standby power budget in always-on automotive modules. |
| TJ(max) | 150 °C - extended junction temperature rating allows operation in engine compartment environments without derating. |
| EAS | 8 mJ per leg - avalanche energy rating supports robustness against inductive switching transients in motor drive freewheel paths. |
| RthJC | 2.0 °C/W per leg - low thermal resistance enables direct heatsink mounting for sustained 10 A/leg operation without forced air. |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with exposed thermal pad; 3-pin configuration (1: Anode A, 2: Common Cathode, 3: Anode B); JEDEC-compliant outline per document 95014; RoHS-compliant Pb-free plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of first Schottky die | Connects to input/high-side node of first power path; must be routed with low-inductance trace for high di/dt stability. |
| 2 | Common cathode | Shared output node for both dies; serves as primary thermal and electrical return path - requires full-surface PCB copper pour. |
| 3 | Anode of second Schottky die | Independent input node enabling dual-channel or center-tap topology; electrically isolated from Pin 1 except through cathode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - suitable for engine control units and ADAS power supplies. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without baking; eliminates pre-conditioning delays in high-volume SMT production. |
| Guard ring structure | Enhances edge termination ruggedness, reducing risk of surface flashover during voltage transients in 48 V mild-hybrid systems. |
| High-purity epoxy encapsulation | Provides superior moisture resistance (IPC/JEDEC J-STD-020 compliant) and mechanical strength for under-hood vibration durability. |
| Low CT (600 pF @ 5 V) | Minimizes capacitive switching loss and EMI generation in >200 kHz SMPS designs - critical for compact USB-C PD adapters. |
Applications
| Automotive DC/DC Converters | Reverse Battery Protection |
|---|---|
Use Scenario: Step-down conversion from 12 V or 48 V battery to 3.3 V/5 V for infotainment and body control modules. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacing MOSFETs in high-current output stage; common cathode simplifies layout and reduces parasitic inductance. Use Value: 0.57 V VF at 125 °C cuts conduction loss by ~35% vs. standard Schottkys, directly improving thermal margin in sealed enclosures. |
Use Scenario: Protection circuit preventing damage when jumper cables are incorrectly connected to vehicle battery terminals. IC Role / Device Role / Timing Role: Low-VF, high-current series-blocking element placed between battery and main power rail. Use Value: 150 °C TJ rating ensures reliable operation during prolonged cranking events where ambient exceeds 105 °C. |
| Industrial Freewheeling Diodes | Server VRM Output Rectification |
Use Scenario: Snubberless flyback path in 24 V industrial PLC power supplies handling inductive loads. IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode absorbing back-EMF from solenoids and relays. Use Value: 10,000 V/μs dV/dt rating prevents false turn-on during rapid voltage transitions, eliminating need for RC snubbers. |
Use Scenario: High-efficiency output rectification in multiphase VRMs powering AI accelerators and Xeon processors. IC Role / Device Role / Timing Role: Dual-die common-cathode configuration enables interleaved current sharing across two phases. Use Value: 2.0 °C/W RthJC per leg allows 10 A/leg operation at <100 °C case temperature with minimal heatsinking - reducing board area by 40% vs. discrete solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS2045CGY | Same D2PAK package, 20 A total, 45 V, but VF = 0.62 V @ 10 A/125 °C; no AEC-Q101 qualification. | Lacks automotive qualification; suitable for industrial/commercial SMPS but not under-hood deployment. | Select when cost sensitivity outweighs automotive compliance and thermal margin is sufficient. |
| ON Semi MBR2045CT | TO-220 package (not surface-mount); identical electrical specs but higher RthJC (3.0 °C/W) and no MSL Level 1 rating. | Requires through-hole assembly and larger heatsink; incompatible with automated SMT lines. | Choose only for legacy through-hole designs where rework to D2PAK is impractical. |
Compared with STPS2045CGY and MBR2045CT, VS-MBRB2045CTTRLP uniquely combines AEC-Q101 qualification, MSL Level 1 compatibility, and lowest VF at elevated temperature - making it the sole choice for space-constrained, thermally aggressive automotive and server power applications requiring zero reflow risk and long-term reliability.

FAQ
What is the maximum junction temperature rating for VS-MBRB2045CTTRLP?
The VS-MBRB2045CTTRLP has a maximum junction temperature (TJ) rating of +150 °C, verified per Vishay's 94305 datasheet. This enables continuous operation in under-hood automotive environments where ambient temperatures exceed 105 °C. The device maintains specified VF and IRM performance up to this limit, with thermal design relying on its 2.0 °C/W RthJC per leg.
Is VS-MBRB2045CTTRLP compatible with lead-free reflow soldering processes?
Yes, VS-MBRB2045CTTRLP is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its Pb-free plating and high-temperature epoxy encapsulation ensure reliability during standard SAC305 lead-free reflow profiles without preconditioning. The D2PAK package's thermal pad enhances heat dissipation during soldering and operation.
Does VS-MBRB2045CTTRLP have AEC-Q101 qualification?
Yes, VS-MBRB2045CTTRLP is explicitly AEC-Q101 qualified, as confirmed in the Vishay 94305 datasheet revision 16-Jan-12. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating its suitability for automotive powertrain and chassis applications.
What is the forward voltage drop of VS-MBRB2045CTTRLP at 20 A and 25 °C?
The forward voltage drop (VFM) of VS-MBRB2045CTTRLP is 0.84 V at 20 A and 25 °C, per the "ELECTRICAL SPECIFICATIONS" table in the Vishay 94305 datasheet. This value reflects worst-case conduction loss under room-temperature full-load conditions and is critical for calculating efficiency in high-current DC/DC stages.
How is the pin configuration arranged on the VS-MBRB2045CTTRLP D2PAK package?
VS-MBRB2045CTTRLP uses a 3-pin D2PAK (TO-263AB) configuration: Pin 1 is Anode A, Pin 2 is the common cathode (electrically and thermally dominant), and Pin 3 is Anode B. The exposed thermal pad (Pin 2) must be soldered to a large PCB copper area for optimal thermal performance - confirmed in Vishay document 95014.
