Overview
The 89CNQ150ASM is a center-tap Schottky rectifier module from the 89CNQ...A series, manufactured by Vishay General Semiconductor - Diodes Division. It features a D-61-8-SM surface-mount package with a common cathode configuration for two elements. Key electrical ratings include a maximum DC reverse voltage of 150 V and an average forward current of 40 A per leg (80 A total). The device exhibits a typical forward voltage drop of 0.69 V at 40 A and 125 °C, with a maximum junction temperature range of -55 °C to 175 °C.
Feature Summary
- Optimized proprietary barrier technology for low forward voltage drop and moderate leakage.
- High purity, high temperature epoxy encapsulation providing enhanced mechanical strength and moisture resistance.
- Guard ring design included for improved ruggedness and long-term reliability.
- Capable of reliable operation up to a 175 °C junction temperature.
Applications
- Switching power supplies
- Converters
- Free wheeling diodes
- Reverse battery protection
Procurement Notes
Verify component authenticity through authorized channels due to potential supply chain variations. Confirm RoHS compliance status as specific datasheets may indicate non-compliance for certain manufacturing batches. Ensure thermal interface materials match the specified mounting torque requirements for the D-61-8-SM package to maintain optimal heat dissipation performance during installation.
Selection Notes
Select this component when a surface-mount solution is required for high-frequency applications needing low forward voltage characteristics. The 150 V rating suits systems operating within this reverse voltage limit. Consider the 40 A per leg current capacity against peak surge requirements, noting the 4300 A IFSM capability for short pulses. Evaluate thermal management needs based on the 0.85 °C/W junction-to-case resistance per leg.
Part Context
This part belongs to the 89CNQ...A series of center-tap Schottky rectifiers. It utilizes the New GenIII D-61 Package, specifically the D61-8-SM variant for surface mount applications. The series is designed for industrial level qualification, offering a balance of high current handling and high-temperature stability compared to standard discrete diodes.
Replacement Considerations
Public confirmed substitute part numbers: 89CNQ150SM, 89CNQ150SMS2.
FAQ
What is the maximum non-repetitive surge current rating?
The maximum peak one-cycle non-repetitive surge current is 4300 A per leg for a 5 µs sine pulse or 3 µs rectangular pulse.
How does the forward voltage drop vary with temperature?
The forward voltage drop is specified as 0.69 V at 40 A and 125 °C, decreasing further at lower temperatures such as 25 °C where it is typically lower.
What is the typical reverse leakage current at elevated temperatures?
The typical reverse leakage current is 1.5 mA at 25 °C and increases to 21 mA at 125 °C.
