1SV322(TPH3,F)

Overview

The Toshiba 1SV322(TPH3,F) is a single varactor diode designed for RF tuning applications. It operates within a reverse voltage range up to 10 V and exhibits a capacitance of 44 pF at zero bias. The device supports a minimum tuning ratio of 4 under specified test conditions. It is housed in the USC-2 surface-mount package, suitable for automated assembly processes. The component functions reliably across an extended temperature spectrum, ranging from -55 °C to +125 °C. Its compact form factor and stable electrical characteristics make it appropriate for high-frequency circuit integration where precise capacitance control is required.

Feature Summary

• Single-element varactor configuration optimized for RF signal processing
• Compact USC-2 surface-mount footprint facilitating dense PCB layouts
• Extended thermal stability supporting operation in harsh environmental conditions

Applications

• RF tuning circuits in communication equipment
• Frequency modulation modules
• VCO (Voltage Controlled Oscillator) designs

Procurement Notes

Verify the specific suffix TPH3,F against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure the sourcing channel provides valid traceability documentation. Cross-reference the part number with current Toshiba Semiconductor and Storage catalogs to validate availability status and compliance with RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when a single varactor diode with a 44 pF baseline capacitance is required. Confirm that the USC-2 package aligns with the target PCB design constraints. Evaluate the 10 V reverse voltage limit against the maximum expected operating voltage in the circuit. Consider the -55 °C to +125 °C operating range to ensure suitability for the intended environmental conditions.

Part Context

This component belongs to the 1SV series of varactor diodes manufactured by Toshiba Semiconductor and Storage. The series is characterized by its use in high-frequency applications requiring variable capacitance controlled by reverse bias voltage. The TPH3,F designation indicates a specific tape-and-reel packaging format intended for surface-mount technology assembly lines.

Replacement Considerations

Consult official Toshiba substitution guides for verified equivalents. Generic varactor diodes may not match the specific tuning ratio or capacitance-voltage characteristics of the 1SV322.
