DMC2640L0R

Overview

The Panasonic DMC2640L0R is a dual NPN digital transistor integrated with built-in bias resistors, designed for compact surface-mount applications. It features a Mini6-G4-B package with dimensions of approximately 2.9x2.8mm. Key electrical specifications include a collector-emitter maximum voltage (VCEO) of 50 V and a continuous collector current rating of 100 mA. The device incorporates typical input resistors of 22 kOhms to facilitate direct interface with logic circuits. It supports operation at temperatures up to +150°C and is available in reel, cut tape, and MouseReel packaging formats.

Feature Summary

• Dual NPN configuration with integrated bias resistors simplifies circuit design by reducing component count.
• Compact Mini6-G4-B package enables high-density mounting on printed circuit boards.
• High thermal stability supports reliable operation in elevated temperature environments.

Applications

• Logic level shifting and switching in consumer electronics
• Driver circuits for small-signal loads in industrial control systems
• Interface modules between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix 'R' against official Panasonic documentation to confirm packaging type and availability status. As this component may be subject to discontinuation or lifecycle changes, consult the manufacturer's latest product notification or authorized distributor inventory lists prior to procurement planning. Ensure compliance with RoHS directives as specified in the official datasheet.

Selection Notes

Select the DMC2640L0R when a dual NPN digital transistor solution is required within space-constrained designs. Confirm that the 50 V VCEO and 100 mA Ic ratings exceed the maximum operational requirements of the target application. Verify that the 22 kOhm internal resistor value aligns with the driving logic voltage levels and desired switching speed characteristics.

Part Context

This component belongs to the Panasonic Digital Transistor series, which integrates bias resistors directly onto the silicon die to simplify switching applications. The DMC2640L0R specifically utilizes the Mini6-G4-B package, offering a compact footprint suitable for modern high-density PCB layouts compared to traditional discrete transistor arrangements.
