BB112 Description

Short technical summary and product information.

The BB112 is a variable capacitance diode manufactured by NXP Semiconductors, suitable for AM tuning applications and VCOs. It features a planar technology fabrication and is encapsulated in a leaded plastic package, specifically the SOD69 (TO-92 variant).

 

Key electrical characteristics include a continuous reverse voltage rating of 12V and a continuous forward current of 50mA. The diode capacitance is specified at 440-540 pF at VR=1V and 17-29 pF at VR=8.5V, both measured at 1 MHz. It also offers capacitance matching to 3% for sets of 3 diodes and a typical capacitance ratio of 18 at 1 MHz.

 

Thermal specifications include an operating junction temperature range of -55 to +85 °C and a storage temperature range of -55 to +125 °C. The diode series resistance is a maximum of 1.5 Ω at 500 kHz.

 

This component is designed for applications requiring electronic tuning in AM radio circuits. Its leaded plastic package facilitates through-hole mounting.
