Overview
The 89CNQ150 is a Schottky diode array manufactured by SMC Diode Solutions, featuring a common cathode configuration for two diodes. It supports a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 40 A per diode. The component utilizes the PRM2-SL surface mount package. Key electrical characteristics include a forward voltage of 1.14 V at 40 A and a reverse leakage current of 1.5 mA at 150 V. It operates within a junction temperature range of -55°C to 175°C.
Feature Summary
- Schottky technology ensures low forward voltage drop and high switching efficiency.
- Common cathode arrangement simplifies circuit design for dual-diode applications.
- Extended thermal capability allows reliable operation up to 175°C junction temperature.
Applications
- DC-DC converter circuits requiring efficient rectification
- Power supply freewheeling diodes
- Reverse polarity protection in automotive systems
Procurement Notes
Verify the specific suffix (SL) against the datasheet to confirm the PRM2-SL package variant. Confirm RoHS3 compliance status for environmental regulations. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or rating mismatches during integration.
Selection Notes
Select this component when a 150 V blocking voltage and 40 A continuous current per leg are required in a compact surface mount form factor. The low forward voltage minimizes conduction losses compared to standard PN junctions. Verify that the PRM2-SL footprint aligns with the PCB layout constraints.
Part Context
This device belongs to the 89CNQ series of high-current Schottky rectifiers from SMC Diode Solutions. The series offers various voltage ratings while maintaining consistent current handling capabilities. The 89CNQ150 specifically targets applications needing robust performance at 150 V reverse voltage.
Replacement Considerations
The 89CNQ150SM is listed as a similar replacement option. Verify pin compatibility and thermal resistance values before substitution. Ensure the alternative meets the same 150 V and 40 A specifications.
