Overview
The 89CNQ150APBF is a center tap Schottky rectifier module from the 89CNQ...A Series, manufactured by Vishay General Semiconductor - Diodes Division. It utilizes proprietary barrier technology to achieve very low forward voltage drop with moderate leakage current. The device supports junction temperatures up to 175°C and features high purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance. Rated at 80 A average forward current per device (40 A per leg) and 150 V maximum DC reverse voltage, it operates within a temperature range of -55 to 175 °C.
Feature Summary
- Optimized for very low forward voltage drop with moderate leakage using proprietary barrier technology
- Reliable operation up to 175°C junction temperature
- High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance
- Guard ring design for enhanced ruggedness and long term reliability
Applications
- Switching power supplies
- Converters
- Free wheeling diodes
- Reverse battery protection
Procurement Notes
Verify that the ordering suffix 'PBF' indicates lead-free compliance as specified in standard industry nomenclature for this manufacturer series. Confirm the specific package variant (D61-8, D61-8-SM, or D61-8-SL) matches the required mounting configuration. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability of the industrial level qualification standards.
Selection Notes
Select this component when a center tap configuration is required for high-frequency switching applications. The 89CNQ150A variant provides a 150 V rating; choose the 89CNQ135A if a 135 V rating is sufficient. Consider the thermal resistance characteristics and the need for a smooth, greased mounting surface to achieve optimal case-to-heatsink performance. Evaluate the surge current capabilities against the specific circuit requirements.
Part Context
This part belongs to the 89CNQ...A Series of center tap Schottky rectifiers. It is housed in the New GenIII D-61 Package, available in through-hole (D61-8), surface mount (D61-8-SM), and low profile surface mount (D61-8-SL) configurations. The series is designed for industrial level applications, offering a balance of high current handling and low forward voltage drop.
Replacement Considerations
Direct substitutes include other parts from the 89CNQ...A Series, such as the 89CNQ135A for lower voltage ratings. Verify pinout compatibility and thermal resistance specifications before substituting with components from different manufacturers.
