BB669E7904

Overview

The BB669E7904 is a varactor diode manufactured by Infineon Technologies, designed for tuning applications. It features a single-diode configuration housed in an SOD-323 surface-mount package with two pins and dimensions of 1.7 x 1.25 x 0.9 mm. The device supports a maximum reverse voltage of 30 V and a forward current of 20 mA. Key electrical parameters include a minimum capacitance of 18 pF and a minimum tuning ratio of 13.5, measured under test conditions from 1 V to 28 V. It operates within a temperature range of -55 °C to +150 °C.

• Features a compact SOD-323 surface-mount package for space-constrained designs
• Capable of operating at elevated temperatures up to 150 °C

Applications

• Tuning circuits
• Voltage-controlled oscillators
• Frequency synthesizers

Procurement Notes

Verify the specific suffix E7904 against official Infineon documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with standard SOD-323 footprint requirements during procurement planning. Cross-reference the part number with current availability status through authorized distributors to avoid obsolete stock issues.

Selection Notes

Select this component when a single varactor diode with a minimum capacitance of 18 pF and a tuning ratio of at least 13.5 is required. Confirm that the 30 V reverse voltage rating meets the circuit's peak reverse bias requirements. Verify that the SOD-323 package size fits the available board space and thermal management constraints.

Part Context

This component belongs to Infineon's varactor diode portfolio, specifically engineered for RF and microwave tuning applications. The BB669 series offers standardized performance characteristics for frequency control circuits. The E7904 suffix typically denotes specific packaging or testing configurations within the product line.

Replacement Considerations

Consult official Infineon substitution guides for verified alternatives. Generic varactor diodes may not match the specific 18 pF minimum capacitance or 13.5 tuning ratio. Ensure any replacement maintains the SOD-323 package and 30 V reverse voltage rating.
