1SV304TPH3F

Overview

The Toshiba Semiconductor and Storage 1SV304TPH3F is a silicon epitaxial planar variable capacitance diode designed for VHF band radio voltage-controlled oscillators. It operates with a maximum reverse voltage of 10 V and supports junction temperatures up to 125 °C. The device provides a typical capacitance of 18.3 pF at 1 V and 6.1 pF at 4 V, measured at 1 MHz. It achieves a high capacitance ratio of 3.0 (typical) between 1 V and 4 V bias points. Electrical performance includes a low series resistance of 0.27 Ω at 470 MHz. The component is housed in a compact USC package.
