DMA264040R

Overview

The Panasonic DMA264040R is a dual PNP digital transistor integrated with internal bias resistors, designed for surface-mount applications. It features a Mini6 G4 B package containing two isolated transistors within a compact footprint of 2.9 x 1.5 x 1.1 mm. The device supports a maximum collector-emitter voltage (Vceo) of 50 V and a continuous collector current (Ic) of 100 mA. Each transistor includes a typical input resistor of 22 kΩ with a resistance ratio of 1. The component operates at a maximum junction temperature of +150 °C and has a power dissipation rating of 300 mW.

Feature Summary

• Dual PNP configuration with integrated bias resistors simplifies circuit design by reducing external component count.
• High thermal stability allows operation up to +150 °C, suitable for demanding environments.
• Compact Mini6 G4 B package provides space-efficient mounting for high-density PCB layouts.

Applications

• General-purpose switching circuits requiring dual PNP logic control.
• Interface drivers in consumer electronics utilizing low-voltage logic levels.
• Power management modules where space constraints limit discrete component usage.

Procurement Notes

Verify the specific suffix and revision level against official Panasonic datasheets before procurement, as manufacturing updates may occur. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the ordering code matches the exact electrical specifications required for the target application to avoid functional mismatches.

Selection Notes

Select this component when a dual PNP solution with built-in base resistors is required for signal switching or buffering. The 22 kΩ input resistance offers a balance between drive current requirements and noise immunity. Consider the 50 V voltage rating and 100 mA current capacity to ensure adequate headroom for the intended load conditions.

Part Context

This part belongs to Panasonic's series of digital transistors, which integrate bipolar junction transistors with on-chip resistors. These components are engineered to replace multiple discrete parts, thereby improving reliability and reducing assembly time in modern electronic devices compared to traditional standalone transistor configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative dual PNP digital transistors from other manufacturers based on pinout, voltage ratings, and package dimensions if sourcing becomes restricted.
