CPH5506-TL-E

Overview

The onsemi CPH5506-TL-E is a discontinued complementary dual bipolar junction transistor (BJT) housed in a surface-mount CPH5 package. It integrates one PNP and one NPN transistor within a single encapsulation to facilitate high-density mounting. The device supports a maximum continuous collector current of 1.5 A and a peak pulse current of 5 A, with a collector-to-emitter voltage rating of 30 V. Key electrical characteristics include a minimum DC current gain (hFE) of 200 at 100 mA and a typical gain-bandwidth product (fT) of 500 MHz. The unit features a low saturation voltage and operates up to a junction temperature of 150 °C.

Feature Summary

• Composite structure containing equivalent PNP and NPN chips for compact design
• Ultrasmall package dimensions enabling miniaturization in end products
• Low collector-to-emitter saturation voltage for efficient switching

Applications

• Relay drivers
• Lamp drivers
• Motor drivers

Procurement Notes

This component has been officially discontinued by the manufacturer and is not recommended for new designs. Verification of availability requires direct contact with an authorized onsemi representative. Sourcing should focus on identifying verified replacement components or alternative devices from the same family that meet the required electrical specifications and package constraints.

Selection Notes

Designers must evaluate the thermal dissipation limits carefully, as the total power dissipation is rated at 1.2 W when mounted on a specific ceramic board. The transition frequency of 500 MHz supports high-speed switching applications. Ensure that the selected replacement maintains the complementary configuration and fits within the physical footprint of the original CPH5 package to preserve board layout integrity.

Part Context

The CPH5506 belongs to the CPH series of complementary dual transistors manufactured by onsemi. This series is designed to replace discrete transistor pairs, reducing component count and assembly time. The specific model integrates a PNP and an NPN transistor, offering a space-saving solution for circuits requiring matched complementary switching elements in a minimal footprint.

Replacement Considerations

The datasheet indicates equivalence to the CPH3115 and CPH3215 chips. Verify pinout compatibility and electrical ratings when selecting substitutes. Consult official distributor databases for currently active parts that match the 30V/1.5A specification and CPH5 package type.
