CA3046 General Purpose Matched NPN Transistor Array DIP-14

CA3046 General Purpose Matched NPN Transistor Array DIP-14

The CA3046 is a general-purpose NPN transistor array housed in a 14-pin Dual In-Line Package (DIP-14). It contains five silicon NPN transistors on a single monolithic substrate, including two transistors that form an internally differentially connected pair. This integrated configuration offers close electrical and thermal matching, making it ideal for low-power applications across a frequency range from DC up to 120 MHz

Key features include low noise operation with a typical noise figure of 3.2 dB at 1 kHz, a wide operating current range, and the ability to function over a full military temperature range from -55°C to +125°C. The maximum collector-emitter voltage is typically 15 V, with a collector current rating up to 50 mA and power dissipation per transistor around 300 mW. The transistor array is commonly used in custom differential amplifiers, temperature-compensated amplifiers, and other analog circuits requiring matched transistor pairs.

Its DIP-14 pin layout facilitates easy mounting on PCBs or breadboards, making it a versatile component for analog circuit design where matched transistor characteristics are critical. The IC provides the advantage of multiple discrete transistors in a compact form factor with integrated matching and low noise performance.
