Product Overview
The BBY6602VH6327XTSA1 is an Infineon hyperabrupt RF tuning diode intended for low-voltage tuning in VCO and tuner circuits. Its selection behavior is defined primarily by the capacitance-versus-bias characteristic, with a specified capacitance ratio of 3.28 between the 1 V and 4.5 V conditions.
For RF tuning work, the 0.25 Ω series resistance and capacitance spread are as important as the nominal capacitance values because they influence Q and achievable tuning performance. This exact OPN is marked discontinued by Infineon, so lifecycle should be considered alongside electrical fit for new procurement or redesign decisions.

Design Considerations
A varactor substitution must be evaluated from the complete capacitance curve, not from a single capacitance value. Check the required tuning span at the actual reverse-bias range and confirm that series resistance and Q remain suitable at the operating RF frequency.
Because the exact OPN is discontinued, a replacement search should also preserve package parasitics and bias-voltage requirements. An electrically similar diode with a different capacitance ratio can shift VCO tuning range or control-voltage sensitivity.
Quality & Verification Support
Third-party inspection or testing can be arranged according to customer requirements. Testing fees are borne by the buyer. Additional verification requirements can be discussed before shipment. After an order is placed, physical product, label, packaging, and Date Code photos may be provided where appropriate.
