CPH5505-TL-E

Overview

The onsemi CPH5505-TL-E is a dual PNP bipolar junction transistor in a CPH5 surface-mount package. It features a collector current of 3 A and a collector-emitter voltage of -30 V. The device has a total power dissipation of 1.2 W and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a minimum DC current gain (hFE) of 200 at -500 mA, a gain-bandwidth product of 380 MHz, and a low saturation voltage of -155 mV at -1.5 A. The component measures 2.9 mm by 1.6 mm with a mounting height of 0.9 mm.

Feature Summary

• Composite configuration containing two equivalent PNP transistors in a single ultrasmall package for high-density mounting.
• Low collector-to-emitter saturation voltage facilitates efficient switching in driver applications.
• High DC current gain ensures effective signal amplification and control.

Applications

• Relay drivers
• Lamp drivers
• Motor drivers
• Flash circuits

Procurement Notes

Verify the ordering suffix TL-E indicates tape-and-reel packaging with a standard quantity of 3,000 pieces per reel. Confirm the Pb Free designation aligns with environmental compliance requirements. Ensure the CPH5 package dimensions match the target PCB land pattern specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact dual PNP solution is required for high-current switching tasks. The CPH5 package offers a smaller footprint compared to discrete alternatives while maintaining a 3 A continuous current rating. Evaluate thermal management needs based on the 1.2 W total dissipation limit under specific mounting conditions.

Part Context

The CPH5505 belongs to the CPH series of composite bipolar transistors manufactured by onsemi. This series integrates multiple chips into a single encapsulation to reduce board space. The CPH5505 specifically utilizes two PNP structures equivalent to the CPH3109, providing a standardized replacement option for designs requiring dual PNP configurations in an SOT-25 compatible form factor.

Replacement Considerations

The datasheet notes equivalence to the CPH3109. Verify pinout compatibility and electrical ratings against existing components during redesign. No other direct substitute part numbers are explicitly listed in the provided documentation.
