Product details
Overview
VS-30CTQ100STRRPBF from Vishay Semiconductors is a high-performance center-tap Schottky rectifier with dual 15 A legs, 100 V reverse voltage rating, 0.67 V forward voltage at 15 A and 125 °C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency DC/DC converters and switching power supplies operating up to 175 °C junction temperature.
For engineers reviewing the VS-30CTQ100STRRPBF datasheet, VS-30CTQ100STRRPBF pinout, VS-30CTQ100STRRPBF application, or VS-30CTQ100STRRPBF equivalent, key selection criteria include its 100 V VR, dual-leg thermal resistance (RthJC = 3.25 °C/W per leg), TO-263AB (D2PAK) package with exposed thermal pad, low 7 mA reverse leakage at 125 °C, and 850 A non-repetitive surge capability - all critical for high-efficiency, high-temperature power conversion designs.
Technical Context
This device integrates two matched Schottky die in a common-cathode center-tap configuration within a single TO-263AB (D2PAK) thermally enhanced package. Its proprietary barrier technology enables stable operation up to 175 °C TJ while maintaining low VF and controlled IRM, distinguishing it from standard silicon diodes and lower-temperature Schottky alternatives.
The structure supports high-frequency switching (>100 kHz) due to low junction capacitance (500 pF at 5 V) and fast dV/dt capability (10,000 V/μs), with ruggedness reinforced by guard ring design and MSL Level 1 moisture sensitivity compliance. Thermal management is enabled via direct-mount thermal pad and low RthJC (3.25 °C/W per leg).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 100 V - Maximum DC reverse voltage; defines safe blocking capability in buck, flyback, or reverse-battery protection circuits. |
| IF(AV) per leg | 15 A - Continuous average forward current per anode leg; supports 30 A total device rating in center-tap topology. |
| VF @ 15 A, 125 °C | 0.67 V - Low conduction loss at elevated temperature; reduces power dissipation and improves efficiency in hot environments. |
| IRM @ 125 °C | 7 mA - Reverse leakage per leg at high temperature; ensures minimal standby loss in battery-powered or always-on systems. |
| EAS | 7.5 mJ - Non-repetitive avalanche energy per leg; provides robustness against inductive switching transients without external snubbers. |
| RthJC per leg | 3.25 °C/W - Junction-to-case thermal resistance; enables precise heatsink sizing and thermal derating for 175 °C max TJ operation. |
| dV/dt | 10,000 V/μs - Voltage slew rate immunity; prevents false turn-on in high-dV/dt noise environments like motor drives or SMPS. |
Pinout & Package
VS-30CTQ100STRRPBF uses the TO-263AB (D2PAK) surface-mount package with an exposed copper thermal pad on the underside for enhanced heat dissipation. The case outline conforms to JEDEC TO-263AB, with dimensions 10.67 mm × 9.65 mm × 4.83 mm (L × W × H) and a 2.54 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode 1) | Anode of first Schottky die | Connects to input/high-side node in center-tap transformer or dual-phase rectification; electrically isolated from Pin 3. |
| 2 (Cathode) | Common cathode connection | Single output node for both diodes; must be routed to low-impedance ground or return path with thermal pad soldered for optimal cooling. |
| 3 (Anode 2) | Anode of second Schottky die | Connects to complementary input node; symmetrical with Pin 1 for balanced current sharing in push-pull or full-wave configurations. |
Key Features
| Feature | Design Value |
|---|---|
| 175 °C maximum junction temperature | Enables operation in under-hood automotive, industrial motor control, and high-density power supplies where ambient exceeds 125 °C. |

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-30CTQ100STRLPBF | Same electrical specs and TO-263AB package; differs only in tape-and-reel orientation (left vs. right) and reel packaging - no functional or thermal difference. | Identical use cases; selected based on SMT line feeder compatibility, not performance or design requirements. | Choose VS-30CTQ100STRRPBF for right-oriented tape feed; otherwise functionally interchangeable. |
| ON Semiconductor NTS4101PT1G | Single 40 V, 3 A Schottky; not center-tap, lower voltage/current rating, SOT-23 package - no pin or thermal compatibility. | Only suitable for low-power, single-leg applications such as USB port protection or microcontroller I/O clamping - not a system-level replacement. | Select only for discrete low-current signal-level protection; not a viable alternative for VS-30CTQ100STRRPBF's 30 A, 100 V power rectification role. |
Compared with VS-30CTQ100STRRPBF, the VS-30CTQ100STRLPBF offers identical performance in a left-feed tape format, while the NTS4101PT1G serves entirely different low-power signal applications - neither provides drop-in replacement capability, and only the former shares full electrical and thermal equivalence.

FAQ
What is the maximum junction temperature rating for VS-30CTQ100STRRPBF?
The VS-30CTQ100STRRPBF has a maximum junction temperature (TJ) rating of 175 °C, verified per Vishay's datasheet revision 08-Dec-14. This allows sustained operation in high-ambient environments such as automotive under-hood locations or enclosed industrial power modules. Derating curves in Figure 5 confirm usable current capacity up to 129 °C case temperature, making VS-30CTQ100STRRPBF suitable for thermally constrained designs where conventional 150 °C-rated diodes would fail.
Does VS-30CTQ100STRRPBF support lead-free reflow soldering?
Yes, VS-30CTQ100STRRPBF meets MSL Level 1 per J-STD-020 and is qualified for lead-free reflow with a maximum peak temperature of 260 °C. Its high-purity epoxy encapsulation and thermal design ensure mechanical integrity and moisture resistance through standard Pb-free profiles. No pre-baking is required, and the TO-263AB package's thermal pad enhances solder joint reliability during repeated thermal cycling - critical for VS-30CTQ100STRRPBF deployment in automotive and industrial production lines.
What is the reverse leakage current specification for VS-30CTQ100STRRPBF at 125 °C?
At 125 °C junction temperature and rated reverse voltage (100 V), the VS-30CTQ100STRRPBF exhibits a maximum reverse leakage current (IRM) of 7.0 mA per leg, as specified in the Electrical Specifications table. This value is confirmed across multiple test conditions and reflects the device's optimized barrier technology for high-temperature stability - significantly lower than generic Schottky diodes of similar rating, which often exceed 20 mA at 125 °C.
Is VS-30CTQ100STRRPBF pin-compatible with other TO-263AB Schottky rectifiers?
VS-30CTQ100STRRPBF uses the standard JEDEC TO-263AB (D2PAK) footprint with 3 terminals (Anode1–Cathode–Anode2) and an exposed thermal pad. While mechanical mounting is compatible with other D2PAK devices, electrical pinout differs from single-diode or dual-common-anode variants. Always verify terminal assignment: Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2 - mismatched routing will cause functional failure. VS-30CTQ100STRRPBF is not a drop-in replacement for non-center-tap D2PAK diodes.
What is the typical junction capacitance of VS-30CTQ100STRRPBF and why does it matter?
The VS-30CTQ100STRRPBF has a typical junction capacitance (CT) of 500 pF per leg at 5 V reverse bias and 25 °C, measured over 100 kHz–1 MHz. This low capacitance minimizes displacement current during high-dV/dt switching, reducing EMI generation and dynamic losses in >100 kHz power converters. In practical terms, it enables cleaner turn-off waveforms and relaxed snubber design compared to higher-CT alternatives - a key advantage for VS-30CTQ100STRRPBF in high-frequency SMPS and resonant topologies.
