89CNQ150SM

Overview

The 89CNQ150SM is a Schottky diode array manufactured by SMC Diode Solutions, featuring one pair of common cathodes. It supports a maximum DC reverse voltage (Vr) of 150 V and an average rectified current (Io) of 40 A per diode. The forward voltage (Vf) is specified at 1.14 V when tested at 40 A. Reverse leakage current is limited to 1.5 mA at the maximum rated voltage. The device operates within a junction temperature range of -55°C to 175°C and utilizes the PRM2-SL surface mount package.

Feature Summary

• Utilizes Schottky technology for high-speed switching capabilities with fast recovery characteristics under 500ns.
• Features a common cathode configuration allowing for dual-diode applications in a single component.
• Designed for surface mount installation using the PRM2-SL package format.

Applications

• High-frequency power supply circuits requiring efficient rectification.
• DC-DC converter stages utilizing low forward voltage drop benefits.
• Free-wheeling diode applications in inductive load protection.

Procurement Notes

Verify the specific suffix designation during procurement to ensure the correct package variant is obtained, as the base part number may correspond to different physical footprints. Confirm RoHS3 compliance status directly with the supplier or manufacturer documentation prior to integration into regulated assemblies. Ensure the ordering quantity matches the standard packaging unit defined in the official datasheet to avoid handling discrepancies.

Selection Notes

Select this component when a 150 V blocking capability and 40 A continuous current rating are required in a surface mount form factor. The low forward voltage characteristic makes it suitable for applications prioritizing efficiency over higher voltage tolerance. Compare thermal resistance specifications against the intended heatsinking strategy to ensure junction temperatures remain within the 175°C limit under full load conditions.

Part Context

This component belongs to the 89CNQ series of Schottky diode arrays produced by SMC Diode Solutions. The series offers various voltage ratings and current capacities tailored for industrial and commercial power electronics. The PRM2-SL package provides a compact solution compared to traditional through-hole alternatives, facilitating automated assembly processes in modern manufacturing environments.

Replacement Considerations

The 89CNQ150ASM from Vishay General Semiconductor is documented as a similar alternative. Verify pin compatibility and thermal performance before substitution. Other variants within the 89CNQ family may offer different voltage ratings but share similar architectural features.
