MPSA56ZL1G

Single Bipolar Transistors Overview

The MPSA56ZL1G is a PNP silicon epitaxial planar transistor manufactured by onsemi. It features a collector-emitter breakdown voltage of 80 V and a continuous collector current rating of 500 mA. The device is housed in the SOT-23 surface-mount package, specifically designated as SC-59. It includes an integrated base resistor with a resistance value of 4.7 kΩ, which simplifies circuit design by reducing component count. The maximum power dissipation is specified at 310 mW.

Single Bipolar Transistors Feature Summary

• Integrated base resistor for simplified drive circuitry
• High breakdown voltage capability for robust operation
• Surface-mount packaging for automated assembly

Single Bipolar Transistors Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic interface buffering

Single Bipolar Transistors Procurement Notes

Verify the specific suffix ZL1G against the official onsemi datasheet to confirm the presence of the integrated 4.7 kΩ base resistor and the SOT-23/SC-59 package configuration. Ensure that the ordering documentation explicitly references the MPSA56ZL1G part number to distinguish it from variants lacking the internal resistor or utilizing different packaging standards.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP solution with built-in biasing is required. The integrated resistor eliminates the need for external base components, saving board space. Verify that the 80 V collector-emitter voltage and 500 mA current ratings align with the specific load requirements of the target application circuit.

Single Bipolar Transistors Part Context

This component belongs to the MPSA56 series of complementary PNP/NPN transistor pairs. It serves as the PNP counterpart to the MPSA55 NPN device. The series is designed for general-purpose amplification and switching tasks where moderate voltage and current handling are sufficient within a small form factor.

Single Bipolar Transistors Replacement Considerations

Cross-reference with MPSA56LT1G for identical electrical characteristics and packaging. Verify compatibility with MPSA56 equivalents from other manufacturers, ensuring the integrated resistor value and package dimensions match the original design constraints.
