Overview
The ZC836ATC is a single varactor diode from Diodes Incorporated, housed in a SOT-23-3 surface-mount package. It features a peak reverse voltage of 25 V and operates within a junction temperature range of -55°C to 150°C. The device exhibits a capacitance of 110 pF at 2 V and 1 MHz, with a Q factor of 100 at 3 V and 50 MHz. The capacitance ratio (C2/C20) is specified as 6.5.
Feature Summary
- Single-channel varactor design for RF tuning applications
- High Q factor performance at 50 MHz
- Wide operating temperature range suitable for industrial environments
Applications
- RF oscillator frequency tuning
- Voltage-controlled filter circuits
- Frequency modulation modules
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm package marking matches SOT-23-3 specifications. Check datasheet revisions for any parameter updates. Ensure storage conditions comply with moisture sensitivity level requirements. Validate supplier documentation against official Diodes Incorporated records before finalizing procurement.
Selection Notes
Select this component when a compact SOT-23-3 footprint is required for high-frequency tuning. Consider the 25 V reverse voltage limit for circuit compatibility. Evaluate the 110 pF baseline capacitance against resonant frequency requirements. Assess thermal management needs given the 150°C maximum junction temperature capability.
Part Context
This part belongs to the 830 Series discrete family from Diodes Incorporated. It serves as a surface-mount alternative to through-hole varactors. The ZC836ATC complements other series components like the ZC834ATA, offering similar packaging but distinct electrical characteristics for varied RF design constraints.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The ZC836ATC may be functionally comparable to the ZC836ATA variant, though specific substitution requires independent verification of pinout and electrical parameters against current design requirements.
