The onsemi CPH3417-TL-E is an NPN transistor housed in a CPH surface-mount package. It supports a maximum DC collector current of 5 A and a maximum collector-emitter voltage of 50 V. The device features a maximum power dissipation of 900 mW and operates at frequencies up to 330 MHz. Physical dimensions are 2.9 x 1.6 x 0.9 mm, with a maximum operating temperature of +150 °C.
Verify the manufacturer designation carefully, as the CPH3417 part number was originally associated with Sanyo Semicon Device before corporate acquisitions. Confirm that the specific suffix -TL-E matches the required tape-and-reel packaging configuration for your automated assembly line. Ensure the component source aligns with current onsemi supply chains to guarantee authenticity and traceability.
Select this component when high-frequency switching speed and low drive voltage compatibility are critical design constraints. The CPH package offers a compact footprint suitable for space-constrained layouts. Evaluate thermal management requirements given the 900 mW power dissipation limit in the small form factor.
This component belongs to the CPH series of high-speed transistors. While historically linked to Sanyo Semiconductor, these parts are now managed within onsemi's portfolio following industry consolidation. The series is characterized by optimized switching characteristics for modern digital and RF applications.
Direct substitutes include the CPH3410, CPH3413, CPH3414, and CPH3418 from the same family. These alternatives share similar ultrahigh-speed switching capabilities and package types.
