Product details
Overview
VS-20CTQ150-1HM3 from Vishay Semiconductors is a high-reliability, AEC-Q101-qualified center-tap Schottky rectifier optimized for 150 V reverse blocking and dual 10 A average forward current per leg. It features 0.66 V forward voltage at 10 A and 125 °C junction temperature, 175 °C maximum operating temperature, and low 5.0 mA reverse leakage at 125 °C - enabling use in automotive DC/DC converters and industrial freewheeling circuits.
For engineers reviewing the VS-20CTQ150-1HM3 datasheet, VS-20CTQ150-1HM3 pinout, VS-20CTQ150-1HM3 application, or VS-20CTQ150-1HM3 equivalent, key selection criteria include its TO-262AA package thermal resistance (RthJC = 1.0 °C/W per package), common-cathode dual-die configuration, 1.0 mJ non-repetitive avalanche energy rating, and MSL Level 1 moisture sensitivity compliance.
Technical Context
This device integrates two independent Schottky die in a single common-cathode TO-262AA package, sharing one cathode terminal and two anode terminals. Its proprietary barrier technology enables stable operation up to 175 °C TJ while maintaining low VF and low IR across temperature - critical for under-hood automotive power stages.
The VS-20CTQ150-1HM3 supports high-frequency switching with 10,000 V/μs dV/dt rating and exhibits 280 pF typical junction capacitance per leg at 5 V reverse bias. Its 8.0 nH series inductance and 1.0 °C/W total junction-to-case thermal resistance support efficient heat extraction in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 150 V - Maximum DC reverse voltage; defines safe blocking capability in battery protection or reverse-polarity input stages. |
| IF(AV) per leg | 10 A - Average forward current per anode leg; supports continuous 20 A total device output in center-tap configurations. |
| VF @ 10 A, 125 °C | 0.66 V - Low conduction loss per leg at elevated temperature; reduces thermal stress in high-ambient environments. |
| IRM max. @ 125 °C | 5.0 mA - Low reverse leakage ensures minimal standby power loss in always-on automotive modules. |
| TJ max. | 175 °C - Enables placement near hot components (e.g., power MOSFETs) without derating in engine control units. |
| EAS per leg | 1.0 mJ - Avalanche energy rating allows safe clamping of inductive switch-off transients in motor drive freewheel paths. |
| RthJC per package | 1.0 °C/W - Low thermal resistance enables direct mounting to heatsinks without thermal interface material degradation concerns. |
Pinout & Package
VS-20CTQ150-1HM3 uses the TO-262AA (also known as modified TO-262) surface-mount-compatible package with three terminals: two anodes (pins 1 and 3) and one common cathode (pin 2). The package features a thermally enhanced base tab for direct heatsink attachment and complies with JEDEC TO-262 mechanical standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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-20CTQ150SHM3 | D2PAK (TO-263AB) package; identical electrical specs but different thermal pad geometry and mounting footprint. | Better suited for automated SMT assembly with larger thermal pad; less compatible with legacy TO-262 footprints. | Select VS-20CTQ150SHM3 when board layout supports D2PAK land pattern and higher-volume pick-and-place is required. |
| ON Semiconductor MUR1020CT | Standard recovery rectifier (not Schottky); 200 V VR, 10 A per leg, VF ≈ 0.95 V at 10 A - higher conduction loss and lower frequency capability. | Acceptable only in low-frequency (<100 kHz), non-automotive applications where efficiency and thermal margin are less critical. | Choose MUR1020CT only if cost is primary driver and 175 °C operation or low VF is not required. |
Compared with VS-20CTQ150SHM3, the VS-20CTQ150-1HM3 offers identical electrical performance in a TO-262AA package optimized for manual or semi-automated assembly and higher thermal mass; versus MUR1020CT, it delivers superior efficiency, faster switching, and automotive-grade reliability - making it unsuitable as a drop-in replacement in legacy designs relying on standard recovery diodes.

FAQ
What is the maximum junction temperature rating for VS-20CTQ150-1HM3?
The VS-20CTQ150-1HM3 has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay's qualified test plan and documented in datasheet revision 31-Aug-2023. This rating applies across the full operating range and enables deployment in under-hood automotive environments where ambient temperatures exceed 125 °C. The device maintains specified VF and IR performance up to this limit.
Is VS-20CTQ150-1HM3 pin-compatible with VS-20CTQ150SHM3?
No, VS-20CTQ150-1HM3 is not pin-compatible with VS-20CTQ150SHM3. While both share identical electrical specifications and internal die configuration, VS-20CTQ150-1HM3 uses the TO-262AA package with a 3-pin straight-lead outline, whereas VS-20CTQ150SHM3 uses the D2PAK (TO-263AB) package with gull-wing leads and a different land pattern. PCB redesign is required for substitution.
Does VS-20CTQ150-1HM3 support lead-free reflow soldering?
Yes, VS-20CTQ150-1HM3 meets MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compliant with lead-free soldering processes. Its halogen-free, RoHS-compliant (M3 suffix) construction ensures compatibility with modern assembly lines without requiring pre-bake or special handling.
What is the avalanche energy rating of VS-20CTQ150-1HM3?
The VS-20CTQ150-1HM3 is rated for 1.0 mJ non-repetitive avalanche energy (EAS) per leg at TJ = 25 °C with IAS = 1 A and L = 2 mH, as confirmed in the "Major Ratings and Characteristics" table of datasheet 95739. This rating validates its ability to safely absorb inductive switching transients in freewheeling and snubber applications without catastrophic failure.
How does the common-cathode configuration of VS-20CTQ150-1HM3 benefit center-tapped transformer designs?
The common-cathode configuration of VS-20CTQ150-1HM3 simplifies secondary-side rectification in center-tapped transformer topologies by consolidating both cathodes into a single terminal (Pin 2), reducing PCB trace count and minimizing parasitic inductance. This layout improves current sharing balance between legs and eases thermal management since both die share the same thermal path to the package base.
