CPH6539-TL-H

Overview

The onsemi CPH6539-TL-H is a dual NPN bipolar junction transistor (BJT) array designed for surface-mount applications. It features two independent NPN elements within a single package, offering a maximum collector current of 1.5 A and a collector-emitter voltage rating of 30 V. The device supports operation up to a frequency of 500 MHz with a power dissipation capacity of 1.2 W. It utilizes the 6-CPH surface-mount package and operates within a temperature range from -55 °C to +150 °C.

Feature Summary

• Dual NPN configuration providing two independent switching or amplification channels in a compact footprint
• High current handling capability of 1.5 A per element for robust load driving
• Wide thermal operating range extending to +150 °C for demanding environments

Applications

• General-purpose signal switching and logic interfacing
• Low-power amplifier circuits requiring dual channel isolation
• Driver stages for relay or LED arrays in consumer electronics

Procurement Notes

Verify the specific suffix TL-H against the official onsemi datasheet to confirm tape-and-reel packaging and binning specifications. Ensure that the 6-CPH package dimensions align with your PCB footprint requirements. Cross-reference the electrical parameters, particularly VCEO and IC limits, with your circuit design constraints before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN topology is required for space-constrained designs. It serves as an alternative to discrete transistors where board area is limited. Consider the 500 MHz frequency limit and 1.2 W power dissipation for thermal management. Evaluate if the 30 V rating meets the system voltage headroom needs compared to higher-voltage alternatives.

Part Context

This part belongs to onsemi's portfolio of bipolar transistor arrays, which consolidate multiple junctions into single packages to reduce assembly complexity. The CPH series typically targets cost-sensitive consumer and industrial applications. As a dual NPN device, it simplifies layout compared to using separate discrete components while maintaining standard BJT performance characteristics.
