Overview
The HVD385BKRF-E is a variable capacitance diode manufactured by Renesas Electronics Corporation. Classified under discrete semiconductor products, this component functions as a varactor or variable reactance device. It is currently in active production and available for procurement. The part is supplied in bulk packaging with a manufacturer standard quantity of 2,830 units per reel. Environmental compliance data indicates the product does not meet RoHS standards, while it holds an EAR99 export classification code.
Feature Summary
- Functions as a voltage-controlled capacitor for tuning applications
- Designed for integration into RF and microwave circuit architectures
Applications
- Voltage-controlled oscillator (VCO) tuning circuits
- RF filter frequency adjustment networks
- Impedance matching network calibration
Procurement Notes
Verify RoHS compliance status prior to implementation, as the component is listed as non-compliant. Confirm that the bulk packaging format aligns with automated assembly requirements. Ensure supply chain stability checks are performed given the specific manufacturing lot availability constraints associated with this discrete semiconductor category.
Selection Notes
Evaluate junction capacitance variation ratios against target circuit bandwidth requirements. Assess reverse breakdown voltage limits to ensure operation within safe DC bias ranges. Verify package compatibility with existing PCB footprint designs and soldering thermal profiles during the prototyping phase.
Part Context
This component belongs to the broader category of tunable semiconductor devices used in signal processing hardware. Unlike integrated circuits, it provides passive reactive control essential for analog front-end adjustments. Its role supports frequency synthesis systems where precise electrical length modulation is required without mechanical components.
Replacement Considerations
Consult official Renesas cross-reference documentation for direct pin-compatible alternatives. Verify that substitute varactors maintain identical capacitance-voltage characteristics and package dimensions to prevent board redesign.
