Product details
Overview
VS-16CTQ100SHM3 from Vishay Semiconductors is a high-performance, AEC-Q101-qualified center-tap Schottky rectifier optimized for 100 V reverse voltage operation, delivering 2 × 8 A average forward current per leg with 0.58 V forward voltage at 8 A and 125 °C junction temperature. It serves as a low-loss freewheeling or reverse-battery protection diode in automotive DC/DC converters and industrial switching power supplies.
For engineers reviewing the VS-16CTQ100SHM3 datasheet, VS-16CTQ100SHM3 pinout, VS-16CTQ100SHM3 application, or VS-16CTQ100SHM3 equivalent, key selection criteria include its 175 °C maximum junction temperature, 7.0 mA reverse leakage at 125 °C, D2PAK (TO-263AB) package thermal resistance of 1.63 °C/W (per package), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This device integrates two independent Schottky die in a common-cathode center-tap configuration within a single D2PAK (TO-263AB) package, enabling dual-leg synchronous rectification without external interconnects. Its proprietary barrier technology ensures stable low-VF and minimal IRM up to 175 °C TJ, critical for high-temperature engine bay applications.
The VS-16CTQ100SHM3 supports high-frequency switching with 10,000 V/μs dV/dt rating and 500 pF junction capacitance per leg at 5 V, while its 7.5 mJ non-repetitive avalanche energy rating allows robust handling of inductive turn-off transients in buck or flyback topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 100 V - Maximum DC reverse voltage; defines safe blocking capability in 48 V automotive systems with 2× transient margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS16H100CG | Same 100 V VR, 16 A IF(AV), but TO-220AC package; higher RthJC = 2.5 °C/W; no AEC-Q101 qualification. | Limited to commercial/industrial use; unsuitable for automotive under-hood deployment due to lower thermal performance and qualification gap. | Select when cost sensitivity outweighs automotive qualification and thermal constraints are relaxed. |
| ON Semiconductor NTS4101PT1G | Single-diode SOT-223; only 1 A IF(AV); not center-tap; lacks avalanche rating and high-temp stability. | Applicable only in low-power auxiliary rails (<5 W); cannot replace VS-16CTQ100SHM3 in primary power paths. | Use only for prototyping or non-critical signal-level clamping-not as functional alternative. |
Compared with STPS16H100CG and NTS4101PT1G, the VS-16CTQ100SHM3 uniquely combines AEC-Q101 qualification, 175 °C operation, center-tap topology, and 1.63 °C/W thermal resistance-making it the sole option for thermally constrained, safety-critical automotive power conversion where dual-leg integration and reliability are mandatory.

FAQ
What is the maximum junction temperature rating for the VS-16CTQ100SHM3?
The VS-16CTQ100SHM3 has a maximum junction temperature (TJ(max)) of +175 °C, verified per AEC-Q101 stress testing. This rating allows uninterrupted operation in high-ambient environments such as engine compartments, where conventional Schottky diodes typically derate above 125 °C. The VS-16CTQ100SHM3 maintains specified VF and IRM performance up to this limit without degradation.
Is the VS-16CTQ100SHM3 pin-compatible with other devices in the VS-16CTQ...SHM3 series?
Yes - all VS-16CTQ...SHM3 variants (e.g., VS-16CTQ060SHM3, VS-16CTQ080SHM3, VS-16CTQ100SHM3) share identical D2PAK (TO-263AB) package dimensions, pinout (Anode–Cathode–Anode), and thermal pad layout. Voltage rating differences (60 V, 80 V, 100 V) do not affect mechanical or electrical interface compatibility, enabling drop-in replacement during design iteration or voltage-scaling upgrades.
Does the VS-16CTQ100SHM3 support high-frequency switching applications?
Yes - the VS-16CTQ100SHM3 is characterized for high-frequency operation with a 10,000 V/μs dV/dt rating and 500 pF junction capacitance per leg at 5 V. These parameters enable reliable use in switching power supplies operating up to 500 kHz, especially in synchronous rectifier stages where fast recovery and low capacitive loading are essential to minimize switching losses.
What is the reverse leakage current specification for the VS-16CTQ100SHM3 at elevated temperature?
The VS-16CTQ100SHM3 specifies a maximum reverse leakage current (IRM) of 7.0 mA per leg at 125 °C and rated VR = 100 V. This value is measured under standardized test conditions and reflects the device's optimized barrier technology for low high-temperature leakage - a key differentiator versus standard Schottky rectifiers that often exceed 20 mA under identical conditions.
How is the VS-16CTQ100SHM3 marked on the package?
The VS-16CTQ100SHM3 is laser-marked on the top surface of the D2PAK package with "16CTQ100SH" followed by date code and factory traceability symbols. The marking conforms to Vishay's standard for TO-263AB devices and aligns with JEDEC outline specifications. No additional alphanumeric codes or suffixes appear on the body beyond this base marking sequence.
