Product details
Overview
80CPQ020 from Vishay is a dual common-cathode Schottky rectifier optimized for 3.3 V output power supplies, rated at 2 × 40 A average forward current per leg, 20 V maximum reverse voltage, and 0.32 V forward voltage drop at 40 A and 150 °C junction temperature. It operates reliably up to 150 °C and features ultra-low VF, high-frequency capability, and guard-ring ruggedness for industrial DC-DC converters and redundant power subsystems.
For engineers reviewing the 80CPQ020 datasheet, 80CPQ020 pinout, 80CPQ020 application, or 80CPQ020 equivalent, key selection criteria include its center-tap common-cathode TO-247AC package, thermal resistance of 0.6 °C/W per leg, 2200 A non-repetitive surge rating, and suitability for high-efficiency 3.3 V synchronous rectification in telecom and server PSUs.
Technical Context
This device implements a dual-leg Schottky barrier structure with proprietary metallization enabling stable operation at TJ = 150 °C. Its low 3.2 mΩ forward slope resistance and 0.185 V threshold voltage support high-current, low-loss conduction in parallel-output or redundant power architectures.
The TO-247AC package provides direct heatsink mounting with RthCS = 0.25 °C/W (greased), and the integrated guard ring enhances avalanche ruggedness-evidenced by 27 mJ non-repetitive avalanche energy and 6 A repetitive avalanche current per leg under defined test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 40 A at TC = 138 °C, 50 % duty cycle - supports continuous high-current output in compact thermal designs |
| VRRM | 20 V - suitable for 3.3 V output rails with margin against transient overvoltage |
| VF @ 40 A, 150 °C | 0.32 V - minimizes conduction loss and heat generation in high-temp environments |
| RthJC per leg | 0.6 °C/W - enables efficient heat transfer to heatsink for sustained 80 A total device current |
| IFSM per leg | 2200 A (5 µs sine) - withstands severe inrush and fault currents without failure |
| IRM @ 150 °C | 600 mA at VR = 10 V - defines leakage-limited hold-off capability at max operating temperature |
| CT @ 5 V | 6500 pF - impacts high-frequency switching behavior and EMI filtering requirements |
Pinout & Package
Package: TO-247AC (JEDEC), center-tap common-cathode configuration with isolated anodes and shared cathode terminal. Mounting base serves as common cathode connection and primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | First anode terminal | Connects to first input/output branch in dual-phase or parallel rectification |
| Pin 2 (Cathode) | Common cathode | Shared output node; electrically and thermally coupled to metal tab/base |
| Pin 3 (Anode 2) | Second anode terminal | Connects to second independent branch - enables center-tap topology or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at high temperature | 0.32 V @ 40 A, 150 °C - reduces power loss by >35 % vs. standard Schottkys at same condition |
| Guard ring protection | Enables 27 mJ non-repetitive avalanche energy - improves survivability during unclamped inductive switching |
| High-purity epoxy encapsulation | Enhances moisture resistance and mechanical strength - qualified for industrial-level reliability (−55 to 150 °C) |
| Optimized for 3.3 V systems | Barrier design balances low VF and leakage - avoids trade-off penalties typical in sub-5 V rectifiers |
| TO-247AC thermal performance | RthJC = 0.6 °C/W per leg - allows 80 A total current with <30 °C rise above heatsink at 138 °C case temp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKT4820 | Single-anode TO-263 package, 40 A/20 V, VF = 0.41 V @ 40 A, 125 °C | Lacks dual-leg integration; requires two devices for same functionality | Preferred when board space permits discrete layout and lower cost per amp is prioritized |
| STPS8020CG | TO-247AC dual common-cathode, 80 A total, VF = 0.44 V @ 40 A, 125 °C, no guard ring | Higher VF and no avalanche ruggedness spec; not rated for 150 °C operation | Acceptable for less demanding 125 °C max TJ environments where cost is critical |
Compared with VSKT4820 and STPS8020CG, the 80CPQ020 delivers superior thermal capability (150 °C TJ), lower VF at elevated temperature, and verified avalanche ruggedness-making it the only option qualified for high-reliability 3.3 V power conversion in thermally constrained industrial and telecom systems.

FAQ
What is the maximum junction temperature rating for the 80CPQ020?
The 80CPQ020 is rated for continuous operation up to 150 °C junction temperature, validated across all electrical parameters including VF, IRM, and avalanche performance. This rating is supported by Vishay's proprietary barrier technology and high-purity epoxy encapsulation, making the 80CPQ020 suitable for thermally demanding applications such as enclosed telecom power supplies and under-hood automotive ECUs where ambient temperatures exceed 85 °C.
Does the 80CPQ020 have a center-tap configuration?
Yes, the 80CPQ020 uses a center-tap common-cathode configuration: Pins 1 and 3 are independent anodes, and Pin 2 is the shared cathode connected to the metal tab. This architecture enables dual-path rectification from separate inputs into a single output rail - ideal for OR-ing, parallel converter outputs, or redundant power subsystems. The 80CPQ020 datasheet explicitly confirms this pinout in Figure 1 and the "PRODUCT SUMMARY" section.
What is the thermal resistance from junction to case for the 80CPQ020?
The 80CPQ020 has a maximum thermal resistance of 0.6 °C/W per leg (junction-to-case), and 0.3 °C/W for the full device. This value is measured under DC operation and reflects the efficiency of heat transfer from each die to the TO-247AC metal tab. When mounted with thermal grease on a heatsink, the typical RthCS is 0.25 °C/W, allowing the 80CPQ020 to sustain 40 A per leg at TC = 138 °C without exceeding 150 °C junction temperature.
Is the 80CPQ020 suitable for reverse battery protection?
Yes, the 80CPQ020 is explicitly cited in its Vishay datasheet (Document Number 93394) as suitable for reverse battery protection due to its low forward voltage drop, high surge current rating (2200 A per leg), and robust guard ring structure. Its 20 V VRRM provides adequate margin for 12 V and 24 V automotive systems, and the 0.32 V VF at 150 °C ensures minimal power dissipation during normal conduction - critical for always-on vehicle modules.
What packaging and marking information applies to the 80CPQ020?
Each 80CPQ020 is supplied in TO-247AC (JEDEC) package with standard tube packaging (25 pieces per tube). The device is marked "80CPQ020" on the case surface, and Vishay's part marking guidelines (Document Number 95226) confirm this format. Lead-free (PbF) versions are available with suffix "-PBF", though the base 80CPQ020 is standard leaded construction unless otherwise ordered.
