KV1560NT – TOKO

The KV1560NT, manufactured by TOKO, is a silicon hyperabrupt junction variable capacitance diode, commonly utilized in voltage-controlled oscillator (VCO) and automatic frequency control (AFC) circuits operating within VHF and UHF frequency ranges. This diode exhibits a nominal capacitance of approximately 2.7 pF at a reverse voltage of 3 V, with a tuning ratio (capacitance change over a specified voltage range) optimized for wideband frequency modulation. The hyperabrupt junction profile provides a highly nonlinear capacitance-voltage characteristic, enabling significant frequency variation with minimal voltage swing. Key electrical parameters include a reverse voltage rating of at least 15 V and a series resistance typically below 1.0 ohm to minimize losses in high-frequency applications. The KV1560NT is typically supplied in a small signal diode package, such as a SOD-323 or similar, facilitating surface-mount assembly.
