Overview
The NRVBD640CTT4G is a silicon Schottky rectifier from onsemi, housed in a surface-mount TO-252 (DPAK) package with three leads. It features a common cathode configuration and supports a maximum repetitive reverse voltage of 40 V. The device handles a continuous forward current of 3 A and exhibits a peak non-repetitive forward surge current capacity of 75 A. Key electrical characteristics include a maximum forward voltage of 900 mV and a reverse current of 100 uA. Operating temperatures range from -65°C to 175°C.
Feature Summary
- Extremely fast switching capability for high-frequency applications
- Extremely low forward voltage drop to minimize power loss
- Platinum barrier construction with avalanche guardrings for enhanced reliability
Applications
- Switchmode power supplies
- Free-wheeling diodes in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the component status carefully before procurement. Official distributor data indicates this part is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm availability through authorized channels and assess long-term supply chain risks associated with end-of-life components.
Selection Notes
Select this component when a low-voltage, high-efficiency rectifier is required in a surface-mount form factor. The TO-252 package provides robust thermal performance suitable for moderate current loads. Ensure the application voltage does not exceed the 40 V rating and that the circuit design accommodates the specific surge current capabilities.
Part Context
This device belongs to onsemi's SWITCHMODE Power Rectifiers series, designed for efficient energy conversion. The NRVBD prefix signifies suitability for automotive and other demanding applications requiring high reliability. It complements the broader portfolio of Schottky barriers optimized for modern power management systems.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout compatibility and thermal resistance specifications if replacing with similar DPAK packages. Ensure new selections meet or exceed the 40 V reverse voltage and 3 A forward current requirements.
