Product details
Overview
VS-20CTQ150SHM3 from Vishay Semiconductors is a high-performance, AEC-Q101-qualified dual common-cathode Schottky rectifier in D2PAK (TO-263AB) package, rated for 150 V reverse voltage, 2 × 10 A average forward current per leg, and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.66 V at 10 A, 125 °C) and low reverse leakage (5.0 mA max at 125 °C), optimized for automotive-grade switching power supplies and reverse battery protection circuits.
For engineers reviewing the VS-20CTQ150SHM3 datasheet, VS-20CTQ150SHM3 pinout, VS-20CTQ150SHM3 application, or VS-20CTQ150SHM3 equivalent, key selection considerations include its center-tap common-cathode configuration, 2.0 °C/W thermal resistance per leg, 10,000 V/μs dV/dt rating, and halogen-free, RoHS-compliant M3 termination - critical for high-reliability automotive and industrial DC/DC converter designs.
Technical Context
This device integrates two independent Schottky die in a single D2PAK package with shared cathode terminal, enabling compact dual-leg rectification without external parallel wiring. Its proprietary barrier technology ensures stable low-leakage operation up to 175 °C TJ, supported by guard ring ruggedization and MSL Level 1 moisture sensitivity rating.
The VS-20CTQ150SHM3 operates with minimal forward conduction loss and fast recovery (no stored charge), making it suitable for high-frequency synchronous rectification and freewheeling in 100–500 kHz SMPS topologies. Its 8.0 nH typical series inductance and 280 pF junction capacitance per leg are characterized at 5 V reverse bias and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max DC Reverse Voltage) | 150 V - supports input stages in 48 V and 60 V automotive systems with 20 % derating margin. |
| IF(AV) per leg | 10 A - enables 20 A total device current handling with thermal sharing across both legs at TC = 154 °C. |
| VF at 10 A, 125 °C | 0.66 V max - reduces conduction loss to ≤6.6 W per leg, easing thermal design in space-constrained modules. |
| IRM max at 125 °C | 5.0 mA - ensures low standby power loss in reverse-battery protection applications under hot ambient conditions. |
| RthJC per leg | 2.0 °C/W - allows direct heatsink mounting with predictable junction-to-case thermal path for reliability modeling. |
| EAS per leg | 1.0 mJ - provides defined avalanche energy capability for unclamped inductive switching stress in flyback/freewheeling use. |
| dV/dt Rating | 10,000 V/μs - prevents false turn-on during fast transient voltage edges in high-speed switching environments. |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with exposed thermal pad; 3-pin configuration (pin 1: Anode Leg 1, pin 2: Common Cathode, pin 3: Anode Leg 2); JEDEC-compliant outline per document 95046; halogen-free, RoHS-compliant M3 termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode Leg 1 | Connects to positive side of first half-bridge or primary-side winding; carries full forward current for that leg. |
| Pin 2 | Common Cathode | Shared output node for both diodes; must be routed with low-inductance, high-current copper for thermal and EMI performance. |
| Pin 3 | Anode of Diode Leg 2 | Connects to positive side of second half-bridge or complementary winding; electrically isolated from Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| 175 °C Junction Operation | Enables deployment in under-hood automotive environments without derating, extending lifetime in high-ambient thermal zones. |

IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode clamping inductive kickback from solenoid drivers and relay coils. Use Value: 10,000 V/μs dV/dt rating prevents spurious conduction during rapid voltage transients, eliminating false triggering and noise coupling. |
| Reverse Battery Protection | Server PSU Output Rectification |
|
Use Scenario: Input polarity protection circuit in automotive infotainment head units and ADAS ECUs. IC Role / Device Role / Timing Role: Low-leakage common-cathode OR-ing diode blocking reverse current when battery is connected backward. Use Value: 5.0 mA max IRM at 125 °C ensures <100 mW standby dissipation even at elevated under-dash temperatures, preventing thermal runaway. |
Use Scenario: Secondary-side rectification in 1U server PSUs operating at 300–500 kHz switching frequency. IC Role / Device Role / Timing Role: High-frequency Schottky rectifier minimizing switching losses and EMI generation in multi-phase VRMs. Use Value: 280 pF CT and 8.0 nH LS per leg reduce ringing amplitude and damping requirements, simplifying EMI filter design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CTQ150-1HM3 | Same die, TO-262AA through-hole package; higher RthJC (1.0 °C/W per package vs. 2.0 °C/W per leg for D2PAK). | Better suited for prototyping, manual assembly, or legacy through-hole board designs requiring mechanical robustness. | Select VS-20CTQ150-1HM3 when thermal interface to heatsink is via bolted TO-262 mount rather than soldered D2PAK thermal pad. |
| ON Semiconductor NT20150CT | 150 V, 2 × 10 A, but rated only to 150 °C TJ; no AEC-Q101 qualification; VF = 0.72 V at 10 A, 125 °C. | Acceptable for commercial-grade industrial power supplies where automotive qualification and extreme temperature margin are not required. | Choose NT20150CT only for cost-sensitive non-automotive applications where 25 °C lower max TJ and missing AEC-Q101 are acceptable trade-offs. |
Compared with VS-20CTQ150-1HM3, the VS-20CTQ150SHM3 offers superior thermal performance in surface-mount layouts and smaller footprint, while the NT20150CT lacks automotive qualification and exhibits higher conduction loss - making VS-20CTQ150SHM3 the optimal choice for AEC-Q101-compliant, thermally demanding applications.

FAQ
What is the maximum junction temperature rating for VS-20CTQ150SHM3?
The VS-20CTQ150SHM3 is rated for a maximum junction temperature (TJ) of +175 °C, validated per AEC-Q101 stress testing and confirmed in Vishay's datasheet revision 31-Aug-2023. This enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures where conventional Schottky diodes typically derate above 125 °C. The VS-20CTQ150SHM3 maintains low IRM and stable VF up to this limit.
Is VS-20CTQ150SHM3 pin-compatible with VS-20CTQ150-1HM3?
No, VS-20CTQ150SHM3 and VS-20CTQ150-1HM3 are not pin-compatible: VS-20CTQ150SHM3 uses the D2PAK (TO-263AB) surface-mount package with 3 pins (anode–cathode–anode), while VS-20CTQ150-1HM3 uses the TO-262AA through-hole package with different lead spacing and mounting geometry. Both share identical electrical characteristics and die structure, but PCB layout and assembly processes differ. The VS-20CTQ150SHM3 requires reflow-compatible land pattern per Vishay doc 95046.
Does VS-20CTQ150SHM3 support reverse battery protection applications?
Yes, VS-20CTQ150SHM3 is explicitly designed for reverse battery protection, as stated in its Vishay datasheet description. Its low reverse leakage (5.0 mA max at 125 °C), 150 V VR rating, and ruggedized guard ring construction ensure robust blocking of reverse current in automotive 12 V systems. When used in common-cathode configuration with anode terminals connected to battery inputs, the VS-20CTQ150SHM3 prevents damage during incorrect battery connection while maintaining low forward loss during normal operation.
What is the thermal resistance from junction to case for VS-20CTQ150SHM3?
The VS-20CTQ150SHM3 has a maximum thermal resistance of 2.0 °C/W per leg (junction-to-case), measured under DC operation per Vishay datasheet document 95739. This value applies individually to each diode leg and assumes proper soldering of the exposed thermal pad to a sufficiently sized copper area on the PCB. The total device RthJC is 1.0 °C/W, reflecting parallel thermal paths - a critical parameter for thermal simulation and heatsink sizing in high-power automotive converters using the VS-20CTQ150SHM3.
Is VS-20CTQ150SHM3 RoHS-compliant and halogen-free?
Yes, VS-20CTQ150SHM3 is RoHS-compliant and halogen-free, as indicated by the "M3" suffix in its part number per Vishay's ordering information table. The M3 designation confirms lead (Pb)-free terminations, compliance with EU RoHS Directive 2011/65/EU, and absence of brominated flame retardants (BFRs) and chlorine-based compounds. This makes the VS-20CTQ150SHM3 suitable for environmentally regulated automotive and industrial applications requiring full material declaration and green manufacturing standards.
