DMA9640T0R

Overview

The DMA9640T0R is a digital transistor manufactured by Panasonic Electronic Components, housed in an SSMini6-F3-B surface-mount package with dimensions of 1.6x1.6mm. This dual NPN configuration features a collector-emitter maximum voltage (VCEO) of 50 V and a continuous collector current rating of 100 mA. The component includes built-in bias resistors with a typical input resistance of 4.7 kOhms. It supports installation via SMD/SMT methods and operates at a maximum temperature of +150 C. Packaging options include Reel, Cut Tape, and MouseReel formats.

Feature Summary

• Dual NPN configuration for compact circuit integration
• Integrated bias resistor network simplifies design
• Small form factor suitable for space-constrained applications

Applications

• General-purpose switching circuits
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging format, as variations exist between reel, cut tape, and mouse reel configurations. Confirm RoHS compliance status through official documentation before procurement. Check for any recent product change notifications or discontinuation notices from Panasonic Industry to ensure long-term availability for production cycles.

Selection Notes

Select this component when a dual NPN digital transistor with integrated biasing is required in a minimal footprint. Ensure the 50 V voltage rating and 100 mA current capacity meet the circuit requirements. Consider the 4.7 kOhm typical input resistance for base drive calculations. Verify that the SSMini6-F3-B package dimensions fit the PCB layout constraints.

Part Context

This part belongs to Panasonic's line of digital transistors, which integrate transistors and resistors into single packages. These components are designed to reduce board space and simplify circuit design by eliminating external bias resistors. The series offers various configurations and resistance values to suit different application needs.

Replacement Considerations

Consult Panasonic Industry for officially confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' digital transistors without verifying pinout, electrical parameters, and package dimensions against official datasheets.
