KVX2152-23-0

Overview

The KVX2152-23-0 is a single-path varactor diode manufactured by Microchip Technology, designed for surface-mount applications in the SOT-23-3 package. It features a maximum peak reverse voltage of 22 V and operates within a temperature range of -55°C to 125°C. Key electrical parameters include a capacitance of 1.3 pF at 20 V and 1 MHz, with a quality factor of 600 measured at 4 V and 50 MHz. The component is classified as a general-purpose varactor diode suitable for RF tuning circuits.

Feature Summary

• Single-channel varactor configuration optimized for compact surface-mount designs
• High Q-factor performance supporting efficient RF signal tuning
• Wide operating temperature range suitable for demanding environments

Applications

• RF tuning circuits requiring variable capacitance control
• Voltage-controlled oscillator (VCO) frequency adjustment
• Phase-locked loop (PLL) filter networks

Procurement Notes

Verify current availability status as distribution channels may indicate discontinued or limited supply. Confirm RoHS3 compliance and MSL level 1 requirements during sourcing. Cross-reference manufacturer part numbers with distributor codes to ensure correct component identification before procurement.

Selection Notes

Select this component when a low capacitance value near 1.3 pF is required at high reverse bias voltages. Ensure the application circuit can accommodate the 22 V peak reverse voltage limit. Verify that the SOT-23-3 package fits the PCB layout constraints and thermal management needs of the design.

Part Context

This device belongs to the KVX series of varactor diodes from Microchip Technology, which are silicon TVAR devices intended for non-hermetic plastic SMT applications. The series provides various capacitance ranges for different RF tuning requirements across communication and industrial equipment.

Replacement Considerations

Check for direct substitutes within the KVX series such as KVX2162-23-0 or KVX2801-23-4 if parameter adjustments are acceptable. Verify pinout compatibility and package dimensions before substituting with other manufacturers' varactor diodes.
