MCH6545-TL-E

Overview

The MCH6545-TL-E is a complementary dual bipolar junction transistor (BJT) array manufactured by onsemi. It integrates one NPN and one PNP transistor within a compact MCPH-6 surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 500 mA. Key electrical characteristics include a transition frequency of 500 MHz, a power dissipation rating of 550 mW, and a low collector-emitter saturation voltage. This component is designed for applications requiring high-speed switching and efficient signal processing in space-constrained environments.

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required tape-and-reel quantities or environmental compliance standards. Confirm that the MCPH-6 footprint matches the target PCB layout. Check for end-of-life status or discontinuance notifications from the manufacturer before finalizing procurement plans to avoid supply chain disruptions.

Selection Notes

Select this component when a complementary pair of NPN and PNP transistors is required in a minimal footprint. Ensure the design operates within the 50 V voltage limit and 500 mA current constraints. Consider the 550 mW power dissipation limit and thermal management requirements for the MCPH-6 package during high-frequency operation.

Part Context

This part belongs to the MCH series of complementary BJT arrays from onsemi. These devices are engineered for digital and analog switching applications where size and performance are critical. The MCPH-6 package provides a robust solution for modern electronics requiring high-density integration of discrete semiconductor components.

Replacement Considerations

MCH6544-TL-E: Similar dual NPN configuration but lacks the complementary PNP element; verify circuit topology compatibility.
