Overview
The ZC836BTC is a single varactor diode manufactured by Diodes Incorporated, designed for voltage-controlled capacitance applications. It features a peak reverse voltage of 25 V and operates within a temperature range of -55°C to 150°C (Tj). The component utilizes an SOT-23-3 surface mount package. Key electrical characteristics include 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
- Provides voltage-variable capacitance functionality for tuning circuits
- Engineered for high-frequency operation with defined Q factor metrics
- Utilizes compact SOT-23-3 surface mount packaging for space-efficient designs
Applications
- Voltage-controlled oscillator (VCO) tuning
- Frequency modulation circuits
- RF filter tuning networks
Procurement Notes
Verify the specific datasheet version and manufacturer lot codes upon procurement. Confirm that the SOT-23-3 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your system's environmental specifications. Cross-reference the capacitance tolerance values against your circuit design margins before finalizing the order.
Selection Notes
Select this component when a small-signal varactor with a 25 V reverse voltage rating is required. Consider the 110 pF baseline capacitance and 6.5 ratio for frequency range needs. Evaluate the Q factor at 50 MHz to ensure sufficient performance for your RF application bandwidth. Verify thermal limits for high-temperature environments.
Part Context
This part belongs to the varactor diode category from Diodes Incorporated. It serves as a passive semiconductor device for adjusting circuit resonance. The SOT-23-3 form factor is standard for low-power surface mount electronics. It complements other discrete components in signal processing and communication hardware.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official distributor databases for cross-references based on identical electrical parameters and package type.
