1SV282TPH3F

Overview

The 1SV282TPH3F is a single varactor diode manufactured by Toshiba Semiconductor and Storage. It features a maximum peak reverse voltage of 34 V and operates at junction temperatures up to 125°C. The device is housed in an ESC package, equivalent to SC-79 or SOD-523, designed for surface mount applications. At a reverse voltage of 25 V and frequency of 1 MHz, the capacitance is specified as 3 pF. The component exhibits a capacitance ratio of 12.5 under C2/C25 conditions. It complies with RoHS standards and has a moisture sensitivity level of 1.

Feature Summary

• Single-channel varactor configuration for RF tuning circuits
• Surface mount construction in compact ESC package
• High junction temperature rating for thermal stability

Applications

• RF tuning circuits requiring variable capacitance
• Voltage-controlled oscillator (VCO) designs
• Frequency modulation modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as the part status may indicate limited availability. Ensure packaging specifications match production requirements before ordering.

Selection Notes

Select this component when a 34 V reverse voltage rating and low capacitance values are required. The 12.5 capacitance ratio supports specific tuning range needs. Verify that the ESC package dimensions fit the PCB layout constraints compared to standard SOD-523 footprints.

Part Context

This part belongs to the 1SV282 series of varactor diodes from Toshiba. It shares the base 1SV282 functionality but includes specific suffix designations for packaging and environmental compliance. It serves as a discrete variable capacitor element within semiconductor diode product lines.

Replacement Considerations
