• High current handling capability with 3 A maximum DC collector current
• Robust voltage ratings supporting 50 V collector-emitter and 100 V collector-base limits
• Surface-mount design optimized for automated PCB assembly processes

Applications

• General-purpose switching circuits in consumer electronics
• Driver stages for relays and solenoids
• Logic level translation interfaces
• Amplifier stages in audio and signal processing equipment

Procurement Notes

Verify the exact ordering suffix against the manufacturer's latest datasheet to ensure correct tape-and-reel packaging and lead-free compliance status. Confirm that the CPH package designation matches the required footprint dimensions for your PCB layout. Cross-reference the part number with authorized distributors to validate authenticity and traceability documentation prior to procurement.

Selection Notes

Select this component when a dual NPN configuration is required in a minimal footprint. Ensure the circuit design accounts for the 900 mW total power dissipation limit and the 3 A current capacity per transistor. Verify that the 50 V collector-emitter voltage exceeds the maximum expected load voltage with adequate safety margin. Consider thermal management strategies if operating near the upper temperature limits.

Part Context

This component belongs to onsemi's CPH series of dual transistors, which are designed to replace discrete single-transistor solutions in space-constrained designs. The CPH package offers improved thermal performance and mechanical stability compared to traditional SOT-23 configurations. This series is commonly used in portable devices where board real estate is limited but higher current handling is necessary.

Replacement Considerations

Direct replacements must match the dual NPN configuration, CPH package type, and equivalent electrical ratings (3 A, 50 V). Verify pinout compatibility before substitution. Alternative dual NPN transistors in similar packages from other manufacturers may require schematic review to ensure functional equivalence.
