Siemens BB 914 Silicon Variable Capacitance Diode Datasheet
The BB 914 is a silicon variable capacitance diode designed for FM radio tuners with an extended frequency band and low supply voltage. It is offered in a monolithic SOT‑23 package and features good linearity of the C‑V curve and a high figure of merit.
The document lists maximum ratings such as a reverse voltage of 18 V, peak reverse voltage of 20 V, forward current of 50 mA, and operating temperature range from –55 °C to +125 °C. Electrical characteristics include reverse current values (20 nA‑200 nA), diode capacitance around 43 pF at 2 V/1 MHz, capacitance ratio of about 2.3, and series resistance of 0.28 Ω.
