Overview
The 89CNQ135 is a Schottky diode array manufactured by SMC Diode Solutions, featuring a one-pair common cathode configuration. It supports an average rectified current of 40A per diode and withstands a maximum DC reverse voltage of 135V. The component utilizes the PRM2-SL surface-mount package and operates within a junction temperature range of -55°C to 175°C. Electrical characteristics include a forward voltage of approximately 1.14V at 40A and a reverse leakage current of 1.5mA at 135V.
Feature Summary
- Schottky barrier technology for low forward voltage drop and high efficiency
- Common cathode dual-diode arrangement simplifies circuit design
- High thermal stability with extended operating temperature range
Applications
- DC-DC converter output rectification
- Free-wheeling diodes in power supply circuits
- Reverse polarity protection systems
Procurement Notes
Verify the specific suffix (e.g., SL or SM) when ordering, as package variations exist within the 89CNQ135 family. Confirm RoHS compliance status, as older Vishay-manufactured versions may differ from current SMC Diode Solutions production. Cross-reference datasheets to ensure pinout compatibility with existing PCB footprints before procurement.
Selection Notes
Select this component for applications requiring moderate voltage blocking with high current capacity in a compact surface-mount form factor. Ensure the thermal management solution accommodates the power dissipation associated with the specified forward voltage at full load. Verify that the 135V rating provides adequate margin for the peak inverse voltage in the target circuit environment.
Part Context
This part belongs to the 89CNQ series of high-current Schottky rectifiers designed for efficient power conversion. The series offers various voltage ratings and packaging options to suit different industrial and consumer electronics requirements. The 89CNQ135 specifically addresses needs for 135V rated applications where space constraints favor surface-mount technologies over through-hole alternatives.
Replacement Considerations
Publicly confirmed substitutes include the 89CNQ135SM and 89CNQ135SMS2 from SMC Diode Solutions. These variants maintain equivalent electrical specifications while potentially differing in packaging or manufacturing origin. Verify mechanical dimensions and thermal characteristics before substituting.
