Product details
Overview
VS-43CTQ100GSPBF from Vishay is a center-tap Schottky rectifier with dual 20 A legs, 100 V maximum reverse voltage, 0.67 V forward voltage at 20 A and 125 °C junction temperature, and D2PAK (TO-263AB) package optimized for high-temperature switching power supplies and reverse battery protection.
For engineers reviewing the VS-43CTQ100GSPBF datasheet, VS-43CTQ100GSPBF pinout, VS-43CTQ100GSPBF application, or VS-43CTQ100GSPBF equivalent, key selection criteria include its 175 °C rated junction temperature, low VF at elevated TJ, center-tap common-cathode configuration, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates two independent Schottky die in a single D2PAK package with shared cathode terminal (Pin 2), enabling synchronous rectification or dual-channel freewheeling in half-bridge topologies. Its proprietary barrier technology ensures stable reverse leakage below 13 mA at 125 °C and 100 V VR.
The 2.0 °C/W thermal resistance per leg (junction-to-case) supports high-power operation up to 135 °C case temperature under 20 A DC per leg, while the 8.0 nH typical series inductance and 10,000 V/μs dV/dt rating support high-frequency (>100 kHz) SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 20 A DC at TC = 135 °C - enables compact heatsink design in high-density 48 V telecom PSUs |
| VRRM | 100 V - supports 48 V nominal input systems with 2× safety margin against transients |
| VF @ 20 A, 125 °C | 0.67 V - reduces conduction loss by ~30 % vs. standard 100 V Schottkys at same current/temp |
| TJ max | 175 °C - allows operation in under-hood automotive environments without derating |
| RthJC per leg | 2.0 °C/W - permits >30 W dissipation per leg with 60 °C ΔT to heatsink |
| IRM @ 125 °C | 13 mA - ensures minimal standby power loss in always-on battery protection circuits |
| dV/dt | 10,000 V/μs - prevents false turn-on during fast-switching SiC/GaN gate drive transitions |
Pinout & Package
D2PAK (TO-263AB) thermally enhanced surface-mount package with exposed copper thermal pad (Pin 2) and three external terminals: Pin 1 (Anode 1), Pin 2 (Common Cathode), Pin 3 (Anode 2). Mounting torque 6–12 kgf·cm; JEDEC-compliant outline per doc. 95014.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS40H100CGY-TR | TO-247AC package, 40 A total, 100 V, VF = 0.72 V @ 20 A/125 °C | Higher thermal mass but through-hole mounting; lower power density than D2PAK | Prefer when board space allows larger footprint and higher surge robustness is required |
| IXYS MBR40100CT | TO-220AB package, 40 A total, 100 V, VF = 0.75 V @ 20 A/125 °C, no AEC-Q101 | Lacks automotive qualification and 175 °C rating; lower thermal performance (RthJC = 2.5 °C/W) | Select only for cost-sensitive industrial applications where AEC-Q101 is not mandated |

FAQ
What is the maximum junction temperature rating for VS-43CTQ100GSPBF?
The VS-43CTQ100GSPBF is rated for continuous operation up to 175 °C junction temperature, verified per AEC-Q101 stress testing and supported by its high-purity epoxy encapsulation. This rating allows deployment in under-hood automotive modules and sealed industrial enclosures without thermal derating, unlike standard Schottky rectifiers limited to 150 °C.
Does VS-43CTQ100GSPBF have AEC-Q101 qualification?
Yes, VS-43CTQ100GSPBF is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number 94222, Revision 23-Mar-10). This qualification covers temperature cycling, humidity bias, and high-temperature operating life tests required for automotive powertrain and body electronics applications.
What is the pin configuration of VS-43CTQ100GSPBF?
VS-43CTQ100GSPBF uses a 3-pin D2PAK (TO-263AB) package with Pin 1 = Anode 1, Pin 2 = Common Cathode (exposed thermal pad), and Pin 3 = Anode 2. The center-tap configuration shares the cathode terminal, enabling dual-output or half-bridge freewheeling topologies without external wiring.
What is the forward voltage drop of VS-43CTQ100GSPBF at 20 A and 125 °C?
The forward voltage drop of VS-43CTQ100GSPBF is 0.67 V at 20 A per leg and 125 °C junction temperature, as specified in the Electrical Specifications table (Document 94222, page 2). This value reflects actual measured performance under worst-case thermal conditions and is critical for calculating conduction losses in high-efficiency power supplies.
Is VS-43CTQ100GSPBF halogen-free and RoHS-compliant?
Yes, VS-43CTQ100GSPBF complies with both halogen-free standards (JEDEC JS709A) and RoHS Directive 2011/65/EU, as stated in the Features section of Document 94222. The "PbF" suffix confirms lead-free termination, and the high-temperature epoxy meets IEC 61249-2-21 definition for halogen-free materials.
