Its headline spec is a capacitance ratio of 15 measured between 1 V and 28 V reverse bias — that 15:1 swing gives an LC tank a wide frequency range without switching in extra capacitors. The junction capacitance sits at 2.754 pF when biased at 28 V and tested at 1 MHz. Peak reverse voltage is rated at 32 V, so the tuning supply rail should stay below that to avoid breakdown. The wide range also gives headroom in hot RF power-amplifier stages or outdoor telecom enclosures where ambient temperatures push high.","metaTitle":"BB173X Varactor Diode, 32V, 15:1 Capacitance Ratio, SOD-523","metaDescription":"BB173X VHF varactor diode, 32 V peak reverse, 15:1 capacitance ratio, 2.754pF @ 28V.
