Product details
Overview
VS-16CTQ080-1HM3 from Vishay Semiconductors is a high-reliability, AEC-Q101-qualified dual-anode Schottky rectifier in TO-262AA package, delivering 2 × 8 A average forward current per leg at TC = 148 °C, 80 V reverse voltage rating, and 0.58 V forward voltage drop at 8 A and 125 °C - optimized for automotive DC/DC converters and industrial freewheeling applications.
For engineers reviewing the VS-16CTQ080-1HM3 datasheet, VS-16CTQ080-1HM3 pinout, VS-16CTQ080-1HM3 application, or VS-16CTQ080-1HM3 equivalent, key selection criteria include its 175 °C junction temperature capability, low 7.0 mA reverse leakage at 125 °C, center-tap common-cathode configuration, MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction.
Technical Context
This device integrates two independent Schottky die in a single common-cathode TO-262AA package, enabling synchronous rectification or dual-path power routing without external cathode tying. Its proprietary barrier technology ensures stable operation up to TJ = 175 °C while maintaining low VF and controlled dV/dt (10,000 V/μs).
The rectifier supports high-frequency switching with 500 pF junction capacitance per leg at 5 V and 8.0 nH typical series inductance, and features guard ring protection for enhanced ruggedness against repetitive avalanche stress (EAS = 7.5 mJ per leg) and mechanical reliability under thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 80 V maximum DC reverse voltage - defines safe blocking capability in 48 V automotive and industrial bus systems |
| IF(AV) per leg | 8 A average forward current - supports continuous 16 A total output in dual-leg configurations at TC = 148 °C |
| VF @ 8 A, 125 °C | 0.58 V - enables <1.2 W conduction loss per leg in high-temp environments, reducing heatsink requirements |
| IRM @ 125 °C | 7.0 mA - low leakage preserves efficiency in high-temperature reverse-biased conditions (e.g., reverse battery protection) |
| TJ max | 175 °C - allows operation in under-hood automotive locations and sealed industrial enclosures without derating |
| RthJC per leg | 3.25 °C/W - enables direct thermal coupling to heatsinks for high-power density designs |
| EAS per leg | 7.5 mJ - withstands unclamped inductive switching events in motor drive freewheeling paths |
Pinout & Package
VS-16CTQ080-1HM3 uses the TO-262AA (Modified JEDEC TO-262) package: 3-pin, through-hole, isolated base tab, with anode–cathode–anode terminal arrangement and mechanical mounting via screw or clamp on the metal base.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKT1680 | Same 80 V VR, TO-220AB package, 16 A total IF(AV), but no AEC-Q101 qualification or guard ring | Lacks automotive qualification and high-temp ruggedness; suited for commercial-grade industrial supplies only | Select when cost sensitivity outweighs automotive compliance and long-term reliability in harsh environments |
| STPS1680CG | 80 V VR, TO-220AC package, 16 A IF(AV), but higher VF (0.75 V @ 8 A, 125 °C) and lower TJ max (175 °C not guaranteed) | Higher conduction loss increases thermal load; less suitable for sustained 125–150 °C ambient operation | Choose only if legacy TO-220AC footprint compatibility is mandatory and thermal margin exceeds 15 °C |
Compared with VSKT1680 and STPS1680CG, VS-16CTQ080-1HM3 delivers verified AEC-Q101 compliance, lower VF at elevated temperature, and integrated guard ring protection - making it the preferred choice for automotive and mission-critical industrial designs where reliability and thermal performance are non-negotiable.

FAQ
What is the maximum junction temperature rating for VS-16CTQ080-1HM3?
The VS-16CTQ080-1HM3 has a maximum junction temperature (TJ max) of +175 °C, validated per AEC-Q101 stress testing and supported by its high-purity epoxy encapsulation and thermal design. This rating allows reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 125 °C. The device maintains specified electrical parameters-including VF and IRM-up to this limit, as confirmed in the Vishay datasheet revision 03-Aug-2023.
Is VS-16CTQ080-1HM3 pin-compatible with TO-220-based Schottky rectifiers?
No, VS-16CTQ080-1HM3 uses the TO-262AA package, which has a different pinout (anode–cathode–anode), lead spacing, and mechanical mounting than TO-220 devices like STPS1680CG or VSKT1680. While both are 3-pin through-hole packages, TO-262AA features a larger base tab, modified lead geometry, and distinct thermal pad contour. Direct PCB replacement requires layout modification; VS-16CTQ080-1HM3 is not a drop-in substitute for TO-220 parts.
Does VS-16CTQ080-1HM3 support bidirectional current flow?
No, VS-16CTQ080-1HM3 is a unidirectional Schottky rectifier. Current flows only from anode (pins 1 or 3) to the common cathode (pin 2); reverse conduction is blocked above its rated VR of 80 V. Its guard ring and avalanche rating (EAS = 7.5 mJ) enhance robustness during transient reverse-voltage spikes, but it does not function as a bidirectional switch or symmetrical device. For bidirectional applications, discrete back-to-back Schottky pairs or dedicated bidirectional switches are required.
What is the meaning of "-1HM3" in VS-16CTQ080-1HM3?
In VS-16CTQ080-1HM3, "-1" denotes the TO-262AA package variant, "H" indicates AEC-Q101 qualification, and "M3" specifies halogen-free, RoHS-compliant, and lead (Pb)-free termination per JEDEC J-STD-020. The "80" identifies the 80 V reverse voltage rating, and "16CTQ" signifies a 16 A total (2 × 8 A) center-tap Schottky rectifier. This full suffix confirms the device meets automotive reliability standards and environmental compliance requirements out of the box.
How does the common-cathode configuration of VS-16CTQ080-1HM3 benefit power supply design?
The common-cathode configuration of VS-16CTQ080-1HM3 integrates two Schottky die sharing a single cathode terminal (pin 2), enabling dual-leg synchronous rectification without external cathode interconnection. This reduces PCB trace inductance, eliminates solder joint reliability risks from paralleled cathodes, and simplifies thermal management via a unified heatsink interface. In buck-derived topologies, it allows independent anode routing (pins 1 and 3) to separate transformer windings or switch nodes while maintaining precise voltage referencing - directly improving efficiency and EMI performance over discrete dual-diode solutions.
