Product details
Overview
88CNQ060ASL from Infineon Technologies (formerly International Rectifier) is a center-tap Schottky rectifier module optimized for low forward voltage drop and high-frequency switching in DC-DC converters and reverse battery protection circuits. It delivers 80 A average forward current per device, 60 V maximum reverse voltage, and operates up to 150 °C junction temperature with 0.56 V forward voltage at 40 A per leg.
For engineers reviewing the 88CNQ060ASL datasheet, 88CNQ060ASL pinout, 88CNQ060ASL application, or 88CNQ060ASL equivalent, key selection criteria include thermal resistance (0.42 °C/W junction-to-case per package), surge capability (5000 A IFSM), ruggedness features (guard ring, transfer-molded D61-8-SL package), and low-profile mechanical design for high-power density layouts.
Technical Context
The 88CNQ060ASL integrates two Schottky diodes in a center-tapped configuration within a single D61-8-SL thermally enhanced epoxy package. Its GenIII barrier technology enables stable operation at 150 °C TJ while maintaining low leakage (240 mA at 125 °C per leg) and fast recovery (dv/dt rating of 10,000 V/µs).
Designed for high-current, high-efficiency power conversion, it supports rectangular waveforms with 50% duty cycle at TC = 120 °C and exhibits 5.5 nH typical series inductance per leg-critical for minimizing switching losses in MHz-range SMPS topologies.
Key Specifications

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-88CNQ060-M3 | Same D61-8 package, identical 60 V/80 A ratings, but rated for 175 °C TJ and uses TrenchStop Schottky process | Better suited for extended high-temp environments (>150 °C ambient); slightly higher VF (0.59 V @ 40 A) | Select when operating ambient exceeds 105 °C or long-term reliability at extreme TJ is prioritized over minimal conduction loss |
| ON Semiconductor NTS4101PT1G | Discrete dual common-cathode Schottky (SOT-223), 60 V/3 A per leg-no center tap, lower current, TO-220 footprint incompatible | Only viable for low-power prototyping or signal-level clamping; not a functional substitute for 80 A power rectification | Consider only for evaluation or auxiliary bias rail protection-not for main power path replacement |
Compared with VS-88CNQ060-M3 and NTS4101PT1G, the 88CNQ060ASL offers optimal balance of low VF, proven 150 °C ruggedness, and D61-8-SL mechanical compatibility for production-grade 48–60 V industrial power systems-neither alternative matches its combination of current rating, thermal performance, and center-tap topology.

FAQ
What is the maximum junction temperature rating for the 88CNQ060ASL?
The 88CNQ060ASL has a maximum junction temperature (TJ) rating of 150 °C, verified per Bulletin PD-20058 rev. B. This rating is enabled by its GenIII Schottky barrier and high-purity epoxy encapsulation. Operation at this temperature requires proper heatsinking-RthJC is 0.42 °C/W per package-and derating of IF(AV) per Fig. 5 when case temperature exceeds 120 °C. The 88CNQ060ASL maintains stable reverse leakage and forward voltage characteristics up to this limit.
Does the 88CNQ060ASL have a center-tap configuration, and how is it implemented?
Yes, the 88CNQ060ASL is a center-tap Schottky rectifier module with two anode terminals (A1 and A2) and one shared cathode (K), forming a symmetrical dual-diode structure. This configuration is physically realized in the D61-8-SL package with internal bonding that places K at the electrical center point. It is intended for use in center-tapped transformer topologies such as forward converters or push-pull circuits-no external center tap is needed. The 88CNQ060ASL datasheet confirms this in both the "Description/Features" and Outline Table sections.
What is the thermal resistance from junction to case for the 88CNQ060ASL, and how should it be applied in thermal design?
The 88CNQ060ASL specifies RthJC = 0.42 °C/W per package (not per leg) under DC operation, as stated in the Thermal-Mechanical Specifications table. This value assumes mounting on a smooth, greased heatsink with device flatness < 5 mils. To calculate junction temperature: TJ = TC + (Pd × 0.42), where Pd = IF(AV) × VF. For example, at 40 A per leg and VF = 0.56 V, Pd ≈ 44.8 W → TJ ≈ TC + 18.8 °C. The 88CNQ060ASL thermal pad must be fully soldered to maximize this performance.
Is the 88CNQ060ASL RoHS-compliant and qualified for industrial applications?
Yes, the 88CNQ060ASL is RoHS-compliant and explicitly qualified for Industrial Level per Infineon's qualification standards referenced in Bulletin PD-20058. It meets JEDEC JESD47 stress testing for temperature cycling, humidity, and high-temperature operating life. The "Industrial Level" designation confirms suitability for extended operation in environments with ambient temperatures up to 85 °C, vibration, and non-condensing humidity-consistent with requirements for telecom power, factory automation, and UPS systems using the 88CNQ060ASL.
What does the "SL" suffix in 88CNQ060ASL indicate, and how does it differ from "SM" or base "A" variants?
The "SL" suffix in 88CNQ060ASL denotes the D61-8-SL package variant: a surface-mount, low-profile version of the D61-8 outline with specific leadframe geometry and mold compound formulation. Per the Outline Table and Part Marking Information, D61-8-SL differs from D61-8-SM (standard profile) and base D61-8 (through-hole) in height (4.5 mm vs. 5.1 mm), thermal pad design, and mounting torque spec (40–58 kg-cm). All three share identical electrical specs, but only the 88CNQ060ASL is optimized for low-profile SMT assembly in space-constrained power modules.
