CA3083MZ

Overview

The CA3083MZ is a general-purpose high-current NPN transistor array manufactured by Renesas Electronics Corporation. It integrates five independent transistors on a common monolithic substrate within a 16-lead SOIC package. The device supports collector currents up to 100mA and operates across a temperature range of -55°C to 125°C. Two internal transistors, Q1 and Q2, are matched at low current for critical offset applications. Key electrical specifications include a maximum collector-to-emitter breakdown voltage of 15V, a gain bandwidth product of 450MHz, and a maximum saturation voltage of 0.7V at 50mA.

Feature Summary

• Integrates five high-current NPN transistors with independent connections on a shared monolithic substrate
• Features a matched pair (Q1 and Q2) optimized for low-current differential amplifier applications
• Includes a separate substrate terminal to ensure isolation between transistors and prevent undesired coupling

Applications

• Signal processing and switching systems operating from DC to VHF
• Lamp and relay driver circuits
• Differential amplifier configurations
• Temperature compensated amplifier designs
• Thyristor firing circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and compliance status. The CA3083MZ designation indicates a lead-free version in a 16-lead SOIC package. Confirm that the procurement source provides valid traceability data and matches the exact part marking specified in the datasheet to avoid counterfeit components.

Selection Notes

Select this component when circuit design requires multiple high-current NPN transistors sharing a common substrate. The integrated matched pair is suitable for precision differential stages where offset parameters are critical. Ensure the application respects the absolute maximum ratings, particularly the collector-to-substrate voltage isolation requirements and thermal dissipation limits for the SOIC package.

Part Context

The CA3083 series consists of versatile NPN transistor arrays designed for flexible circuit implementation. The CA3083MZ variant specifically utilizes a surface-mount SOIC package. This family allows designers to consolidate multiple discrete transistors into a single component, reducing board space while maintaining independent control over each transistor element through dedicated terminals.

Replacement Considerations

Direct replacements include the CA3083Z (Pb-free PDIP), CA3083M96 (SOIC Tape and Reel), and CA3083MZ96 (Pb-free SOIC Tape and Reel). Verify pinout compatibility and package dimensions before substitution. Cross-reference with other manufacturers' equivalent transistor arrays if form-factor changes are acceptable.
