Overview
The 1N5711UBCC is a small-signal Schottky barrier diode manufactured by Microchip Technology. It utilizes silicon technology and is housed in the UB-3 ceramic surface-mount package. The device features a maximum repetitive reverse voltage of 70 V and an average forward current rating of 33 mA. It is designed for high-reliability applications, offering low reverse leakage characteristics and ultrafast switching capabilities.
Feature Summary
- Ceramic surface mount construction for high reliability
- Low reverse leakage current characteristics
- Ultrafast switching performance
Applications
- High-level UHF/VHF detection
- Pulse applications with broad dynamic range
- Military grade circuits requiring MIL-PRF-19500/444 qualification
Procurement Notes
Verify the specific revision level and qualification status (JAN, JANTX, or JANTXV) against the official datasheet before procurement. Confirm that the UB-3 package dimensions match the design constraints. Ensure compliance with RoHS directives if required by the end application. Check for lead-free soldering compatibility during assembly.
Selection Notes
Select this component when a hermetically sealed, surface-mount Schottky diode is required for RF detection or pulse applications. It serves as the surface mount equivalent to the axial-leaded 1N5711. Consider thermal resistance and junction temperature limits (-65°C to +150°C) for high-temperature environments. Verify pinout compatibility with existing footprints.
Part Context
This part belongs to the 1N5711UB series, which includes variants like 1N5711UBD and 1N5711UBCC. These are qualified per MIL-PRF-19500/444. The series offers unidirectional, doubler, common anode, and common cathode polarities. It replaces older through-hole versions while maintaining military-grade performance standards.
Replacement Considerations
Direct substitutes include other 1N5711UB variants such as 1N5711UBD or 1N5711UBCA, provided the package and qualification levels match. Axial equivalents like 1N5711-1 require PCB redesign. Verify electrical parameters and thermal characteristics before substitution.
