Overview
The HVD396CKRF-E is a variable capacitance diode designed for Voltage Controlled Oscillator (VCO) applications. It features a minimum capacitance ratio of 2.30 and exhibits good linearity in its C-V curve. The device operates within a reverse voltage range up to 10 V, with a maximum junction temperature of 125°C. At 1 MHz, the capacitance ranges from 5.20 pF at 4 V to 17.5 pF at 1 V. Series resistance is specified at a maximum of 0.4 Ω at 470 MHz. The component utilizes a Super small Flat Package (SFP) suitable for surface mount design.
Feature Summary
- High capacitance ratio ensuring effective tuning range
- Good linearity of the capacitance-voltage characteristic curve
- Super small Flat Package (SFP) optimized for surface mount integration
Applications
- Voltage Controlled Oscillators (VCO)
- Frequency modulation circuits
- Tuning networks in RF systems
Procurement Notes
Verify the specific suffix 'KRF' against official Renesas documentation to confirm packaging or tape-and-reel specifications. Ensure circuit designs incorporate safety measures such as auxiliary circuits to prevent malfunction. Evaluate all provided electrical data as a total system before finalizing product applicability.
Selection Notes
Select this component when a high capacitance ratio and linear C-V response are required for VCO designs. Consider the SFP package dimensions for surface mount constraints. Verify that the operating frequency aligns with the specified series resistance characteristics at 470 MHz and capacitance values at 1 MHz.
Part Context
This component belongs to the HVD396C family of variable capacitance diodes originally developed by Hitachi Semiconductor. Following the transfer of semiconductor operations on April 1, 2003, these products were integrated into Renesas Technology Corporation's portfolio. The datasheet retains original Hitachi branding but represents current Renesas manufacturing standards.
Replacement Considerations
Consult official Renesas documentation for verified substitute part numbers. Generic replacements may not match the specific capacitance ratio or series resistance requirements of the HVD396C.
