Product details
Overview
VS-48CTQ060SPBF from Vishay Semiconductors is a high-performance dual common-cathode Schottky rectifier in TO-263AB (D2PAK) package, rated for 60 V reverse voltage and 2 × 20 A average forward current per leg, with 0.58 V forward voltage at 20 A and 125 °C junction temperature-optimized for switching power supplies and reverse battery protection circuits.
For engineers reviewing the VS-48CTQ060SPBF datasheet, VS-48CTQ060SPBF pinout, VS-48CTQ060SPBF application, or VS-48CTQ060SPBF equivalent, key selection criteria include its 150 °C maximum junction temperature, low 8.26 mΩ forward slope resistance, 13 mJ non-repetitive avalanche energy rating, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates two independent Schottky die in a single center-tap–compatible common-cathode configuration, enabling synchronous rectification or dual-channel freewheeling. Its proprietary barrier technology minimizes reverse leakage (89 mA max at 125 °C) while sustaining 150 °C TJ operation.
The TO-263AB package delivers 1.0 °C/W maximum thermal resistance (junction-to-case per package), supported by a thermally enhanced epoxy encapsulation and guard ring structure-meeting MSL Level 1 and LF peak of 260 °C for lead-free reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 60 V - Maximum DC reverse voltage; defines safe blocking capability in battery protection and DC/DC converter outputs. |
| IF(AV) per leg | 20 A - Continuous average forward current per diode leg at TC = 111 °C; supports high-current secondary-side rectification. |
| VF at 20 A / 125 °C | 0.58 V - Low conduction loss enabling >92 % efficiency in 12 V–48 V output stages. |
| RthJC (per package) | 1.0 °C/W - Enables direct heatsink mounting without derating for 40 W total dissipation at ΔT = 40 K. |
| EAS per leg | 13 mJ - Avalanche energy rating allows robust unclamped inductive switching in flyback or buck converters. |
| dV/dt | 10,000 V/μs - High voltage transient immunity prevents false turn-on during fast-switching MOSFET gate drive transitions. |
| TJ max | 150 °C - Extended junction temperature rating permits operation in under-hood automotive environments without forced cooling. |
Pinout & Package
VS-48CTQ060SPBF uses the TO-263AB (D2PAK) surface-mount package with exposed thermal pad on the underside. Pin assignments are verified per Vishay document 95014: Pin 1 and Pin 3 are anodes; Pin 2 is the common cathode terminal. The package meets JEDEC outline TO-263AB and supports mechanical mounting via the thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (Leg 1) | Input terminal for first Schottky diode; connects to high-side switch node in synchronous rectifier topologies. |
| Pin 2 | Common Cathode | Shared output node for both diodes; serves as low-impedance return path to ground or output rail in dual-leg configurations. |
| Pin 3 | Anode (Leg 2) | Input terminal for second Schottky diode; enables independent control or paralleling with Pin 1 for higher current handling. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY20060MD | Same 60 V VR and 2 × 20 A rating, but TO-252 (DPAK) package; RthJC = 2.5 °C/W (per leg); no AEC-Q101 qualification. | Limited to commercial/industrial ambient (≤125 °C); unsuitable for under-hood automotive deployment. | Select when cost-sensitive, lower-power (<15 A/leg) designs require smaller footprint and thermal performance is less critical. |
| STPS40M60CG | 60 V, 2 × 20 A, TO-263AB package, AEC-Q101 qualified; VF = 0.65 V @ 20 A/125 °C; EAS = 10 mJ. | Slightly higher conduction loss and lower avalanche robustness; validated for same automotive applications but with narrower safety margin. | Choose when supply chain diversification is required and minor efficiency trade-off (≈0.7 % at full load) is acceptable. |
Compared with VSKY20060MD and STPS40M60CG, the VS-48CTQ060SPBF delivers the lowest VF (0.58 V) at high temperature and highest EAS (13 mJ), making it optimal for thermally constrained automotive and high-reliability industrial converters where efficiency and ruggedness are co-prioritized.

FAQ
What is the maximum junction temperature rating for VS-48CTQ060SPBF?
The VS-48CTQ060SPBF has a maximum junction temperature (TJ max) of +150 °C, verified per Vishay document 94230. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial power supplies without active cooling. The device maintains specified electrical parameters-including 0.58 V VF and 89 mA IRM-up to this limit, supported by its high-purity epoxy encapsulation and guard ring design.
Is VS-48CTQ060SPBF AEC-Q101 qualified?
Yes, the VS-48CTQ060SPBF is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 08-Dec-14 (document 94230). This qualification covers stress testing for temperature cycling, humidity bias, and high-temperature operating life-ensuring suitability for automotive powertrain, body control, and ADAS subsystems where zero-defect reliability is mandated.
What package type does VS-48CTQ060SPBF use, and how is thermal management handled?
VS-48CTQ060SPBF uses the TO-263AB (D2PAK) surface-mount package with an exposed thermal pad. Thermal management is enabled by a maximum junction-to-case thermal resistance of 1.0 °C/W (per package), allowing direct attachment to a heatsink or PCB copper pour. The package complies with JEDEC TO-263AB and supports reflow soldering up to 260 °C peak, per MSL Level 1.
How does the common-cathode configuration of VS-48CTQ060SPBF benefit circuit design?
The common-cathode configuration of VS-48CTQ060SPBF integrates two Schottky diodes sharing a single cathode terminal (Pin 2), reducing PCB layout complexity and parasitic inductance in dual-path applications like interleaved converters or center-tapped transformer rectifiers. It eliminates the need for external cathode tying, improves current sharing accuracy, and supports independent anode routing (Pins 1 and 3) for phase-controlled or redundancy-based topologies.
What is the avalanche energy rating of VS-48CTQ060SPBF, and why does it matter?
The VS-48CTQ060SPBF has a non-repetitive avalanche energy rating (EAS) of 13 mJ per leg, measured at TJ = 25 °C with IAS = 1.50 A and L = 11.5 mH. This rating ensures survivability during unclamped inductive switching events-such as MOSFET turn-off in buck or flyback converters-without catastrophic failure. It directly supports robust design in high-di/dt power stages where snubberless operation is desired.
