Product details
Overview
225CNQ015 from Infineon Technologies is a center-tap Schottky rectifier module rated for 220 A average forward current, 15 V DC reverse voltage, and 0.32 V forward voltage drop per leg at 110 A and 125 °C junction temperature-optimized for OR-ing in parallel power supplies and redundant power subsystems.
For engineers reviewing the 225CNQ015 datasheet, 225CNQ015 pinout, 225CNQ015 application, or 225CNQ015 equivalent, key selection criteria include ultra-low VF at high temperature, 10,800 A non-repetitive surge capability, TO-244AB thermal performance (0.20 °C/W RthJC per package), and ruggedized guard-ring construction for long-term reliability in industrial-grade power systems.
Technical Context
This dual-anode, common-cathode Schottky module uses proprietary barrier technology to sustain reliable operation up to 125 °C junction temperature with VR < 5 V. Its low VF (0.32 V @ 110 A, 125 °C) and high-frequency capability stem from minimized carrier lifetime and optimized metal-semiconductor interface.
The TO-244AB package integrates two symmetrical Schottky legs sharing a common cathode terminal, enabling balanced current sharing in OR-ing configurations. Thermal resistance is specified as 0.20 °C/W junction-to-case (per package), supported by high-purity epoxy encapsulation and mechanical mounting via 1/4-20 slotted hex base.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 220 A at 74 °C case temperature, 50% duty cycle rectangular waveform - supports high-current DC-DC output stages without forced air cooling |
| VRRM | 15 V - suitable for low-voltage OR-ing in 12 V battery-backed or telecom power systems |
| VF (per leg) | 0.32 V @ 110 A, TJ = 125 °C - reduces conduction loss by >30% vs. standard Schottkys at same rating |
| IFSM | 10,800 A @ 5 µs sine - withstands severe inrush and fault currents in redundant supply switching |
| RthJC (per package) | 0.20 °C/W - enables efficient heat transfer to heatsink, critical for sustained 220 A operation |
| CT (per leg) | 7700 pF @ 5 V - limits high-frequency switching noise in fast transient applications |
| dv/dt rating | 10,000 V/µs - prevents false turn-on during rapid voltage transients in high-speed power switching |
Pinout & Package
Package: TO-244AB (Modified JEDEC), isolated copper base with 1/4-20 slotted hex mounting, common cathode configuration, dual anode terminals (Anode 1 / Anode 2), and insulated terminal lugs for high-current busbar connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Common Cathode | Shared cathode node for both Schottky legs | Enables center-tap topology for OR-ing; requires low-inductance, low-impedance return path to system ground or rail |
| Anode 1 | First Schottky anode input | Connects to first power source (e.g., PSU #1); must be routed with matched impedance to Anode 2 for current balance |
| Anode 2 | Second Schottky anode input | Connects to second power source (e.g., PSU #2); symmetry with Anode 1 ensures equal forward voltage and thermal distribution |
| Base (Mounting Surface) | Thermal and electrical isolation plane | Electrically isolated copper base transfers heat to heatsink; rated for 24–35 kg-cm mounting torque |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at high temperature | 0.32 V @ 110 A, 125 °C - directly reduces power loss and thermal stress in thermally constrained enclosures |
| Guard ring structure | Enhances edge termination ruggedness - improves long-term reliability under repetitive surge and reverse-bias stress |
| High-purity epoxy encapsulation | Resists moisture ingress and mechanical shock - validated for industrial-level qualification per Infineon standards |
| Center-tap dual-leg architecture | Enables true OR-ing with automatic current sharing - eliminates need for external balancing resistors or controllers |
| Low series inductance | 7.0 nH per leg (measured from terminal hole to mounting plane) - minimizes voltage overshoot during fast di/dt events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKT220A15 | Same 15 V VRRM, 220 A IF(AV), but TO-269AA package; RthJC = 0.25 °C/W (per leg), VF = 0.35 V @ 110 A, 125 °C | Slightly higher VF and thermal resistance; less optimal for space-constrained OR-ing where baseplate thermal coupling is critical | Prefer 225CNQ015 when lowest possible conduction loss and package-level thermal resistance are required |
| IXYS DSSK2X121-015A | 15 V, 2 × 120 A legs; TO-247-3L package; VF = 0.39 V @ 120 A, 125 °C; no common-cathode center-tap | Discrete dual-die layout lacks integrated center-tap symmetry; requires external interconnect and balancing | Choose 225CNQ015 for plug-in OR-ing simplicity; select DSSK2X121-015A only if modular layout or separate cathode routing is needed |
Compared with VSKT220A15 and DSSK2X121-015A, the 225CNQ015 delivers superior thermal integration (0.20 °C/W per package vs. 0.25 °C/W or discrete paths), lower VF at operating temperature, and native center-tap architecture-making it the most direct solution for high-reliability, high-current OR-ing where thermal and layout efficiency are prioritized.

FAQ
What is the maximum junction temperature rating for the 225CNQ015?
The 225CNQ015 has a maximum junction temperature rating of 125 °C, validated for continuous operation under rated conditions including VRRM ≤ 5 V. This rating is enabled by proprietary barrier technology and high-purity epoxy encapsulation, supporting reliable use in enclosed industrial environments without derating below ambient 85 °C.
Does the 225CNQ015 support center-tap OR-ing configurations?
Yes, the 225CNQ015 is explicitly designed as a center-tap Schottky rectifier module with dual anodes (Anode 1 and Anode 2) and a shared common cathode terminal. This architecture enables true passive OR-ing between two independent power sources without external balancing components or control circuitry.
What is the thermal resistance from junction to case for the 225CNQ015?
The 225CNQ015 specifies RthJC = 0.20 °C/W per package (not per leg), measured from junction to the isolated copper base. This value reflects the total thermal path through both legs and is critical for heatsink sizing in high-current applications such as 220 A DC-DC outputs.
How does the 225CNQ015 handle surge current events?
The 225CNQ015 supports a non-repetitive peak surge current of 10,800 A for 5 µs (sine wave), verified per Fig. 7 in Bulletin PD-2.294. This capability allows it to survive inrush, short-circuit, and hot-swap transients in redundant power systems without degradation when mounted with proper thermal interface.
Is the 225CNQ015 qualified for industrial applications?
Yes, the 225CNQ015 is designed and qualified to Industrial Level standards per Infineon's internal qualification program, covering temperature cycling, humidity, and long-term reliability testing. Its -55 to 125 °C operating range, guard-ring ruggedization, and high-purity epoxy encapsulation confirm suitability for harsh industrial environments.
