Overview
The Microchip Technology 1N6642UBD/TR is a small signal switching diode designed for surface mount applications. It features a single configuration housed in a D-5D-2 package. Key electrical parameters include a peak reverse voltage of 75 V and a maximum surge current of 2.5 A. The forward current rating is 100 mA, with a forward voltage of 1.2 V at operating conditions. Reverse leakage current is specified at 500 nA. The device exhibits a fast recovery time of 5 ns and a maximum diode capacitance of 5 pF. It operates within a temperature range from -65 C to +175 C.
Feature Summary
- Surface mount hermetic ceramic construction suitable for harsh environments
- Ultrafast switching characteristics with low reverse recovery time
- High thermal stability supporting extended operating temperatures
Applications
- Signal or computer diode circuits
- High frequency switching applications
- Harsh environment electronic systems
Procurement Notes
Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm the D-5D-2 package dimensions match the target PCB footprint. Ensure the 75 V reverse voltage rating meets the circuit requirements. Check for any recent Product Change Notifications regarding material or process updates. Validate that the hermetic seal specification aligns with environmental protection needs.
Selection Notes
Select this component for designs requiring a hermetically sealed surface mount switching diode. The 100 mA forward current and 75 V reverse voltage define the operational limits. Consider the 5 ns recovery time for high-speed signal processing. The wide temperature range supports operation in extreme conditions. Compare against through-hole variants if board space allows alternative mounting styles.
Part Context
This part belongs to the 1N6642 series of switching diodes manufactured by Microchip Technology. It shares core specifications with the standard 1N6642 but utilizes a surface mount ceramic package instead of through-hole leads. The series is characterized by fast recovery times and robust construction. Other variants in the family may offer different voltage ratings or package types.
Replacement Considerations
The JANS1N6642UBD/TR is a qualified aerospace variant of this component. Verify pinout compatibility between the standard and military-grade versions before substitution. Ensure the replacement matches the hermetic sealing requirements of the original design.
