CA3045F Description

Short technical summary and product information.

The SIL CA3045F is a monolithic transistor array consisting of five general-purpose NPN silicon transistors on a common substrate. Two of these transistors are internally connected to form a differential pair, offering advantages for low-power systems operating from DC through the VHF range. This device is a direct electrical and mechanical replacement for the obsolete Intersil CA3045F.

Key electrical characteristics include a collector current of up to 50mA, a collector-to-emitter breakdown voltage of 15V minimum, and a transition frequency (fT) of 550MHz typical. The array boasts a low noise figure of 3.2dB typical at 1kHz and features two matched transistors with a VBE match of ±5mV and an IO match of 2µA maximum. The operating temperature range spans from -55°C to 125°C.

The CA3045F is supplied in a 14-lead Ceramic Dual-In-Line Package (CERDIP-14). Its design makes it well-suited for applications requiring close electrical and thermal matching, such as custom-designed differential amplifiers and temperature-compensated amplifiers. It can also be used as discrete transistors in conventional circuits.
