At 28 V and 1 MHz it measures 2.89 pF, and the capacitance ratio from 1 V to 28 V is 22. ## Voltage and temperature handling Peak reverse voltage is rated at 32 V, so the tuning voltage should stay below that to avoid breakdown. Housed in an SC-79 / SOD-523 surface-mount package, the BB175X is suited for compact RF front-ends. The supplier device package is SOD-523. No end-of-life notice or last-time-buy is on record. For new designs, this part carries no immediate obsolescence risk.","metaTitle":"BB175X Varactor Diode, 32V, 2.89pF, SOD-523","metaDescription":"BB175X VHF varactor diode, 32 V peak reverse, 2.89pF @ 28V, capacitance ratio 22.
