BBY 53-03LRH E6327

Overview

The BBY 53-03LRH E6327 is a silicon tuning diode manufactured by Infineon Technologies, designed for voltage-controlled oscillator (VCO) and low-voltage tuner applications. It features a dual common cathode configuration housed in an SOT-23-3 surface-mount package. The device operates with a maximum reverse voltage of 6 V and a forward current limit of 20 mA. Key electrical parameters include a capacitance of 4.8 pF and a minimum tuning ratio of 1.8 under specified test conditions. It supports a wide operating temperature range from -55°C to +125°C.

Feature Summary

• Dual common cathode varactor topology for integrated circuit design
• Silicon construction optimized for low-voltage tuning applications
• Surface-mount SOT-23-3 packaging for automated assembly

Applications

• Voltage-controlled oscillators (VCO)
• Low-voltage tuner circuits
• Frequency modulation modules

Procurement Notes

Verify component authenticity through authorized Infineon channels or certified distributors. Request original datasheets and material content declarations to confirm RoHS compliance and traceability. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity damage prior to soldering.

Selection Notes

Select this component when a dual varactor structure is required within a compact SOT-23 footprint. Confirm that the 6 V reverse voltage rating meets the specific bias requirements of the target circuit. Evaluate the 4.8 pF baseline capacitance against the desired frequency range to ensure adequate tuning coverage for the application.

Part Context

This part belongs to the BBY 53 series of silicon tuning diodes. The suffix 'E6327' typically denotes specific tape-and-reel packaging configurations used for high-volume manufacturing. The '03' variant often indicates specific binning or packaging details distinct from standard bulk versions.

Replacement Considerations

Direct pin-compatible substitutes may include other dual common cathode varactors in SOT-23 packages. Verify that replacement parts match the 6 V reverse voltage and 4.8 pF capacitance specifications to maintain circuit performance integrity.
