DTC123JE-TP

Overview

The DTC123JE-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC) in the SOT-523 surface-mount package. It integrates bias resistors to simplify circuit design, eliminating the need for external input components. Key electrical specifications include a maximum supply voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 150 mW. The device features a typical transition frequency of 250 MHz and an input resistance (R1) of 2.2 kΩ with a resistance ratio (R2/R1) of 21. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Built-in thin-film bias resistors enable inverter circuit configuration without external input resistors.
• Resistors provide complete isolation to allow negative biasing and minimize parasitic effects.
• Halogen-free 'Green' device construction with UL 94 V-0 flammability rated epoxy.
• Moisture Sensitivity Level 1 classification for simplified storage and handling.

Applications

• Inverter circuits requiring simplified input configurations
• General-purpose switching applications in consumer electronics
• Driver circuits for logic interfaces

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from Micro Commercial Components Corp. to avoid counterfeit parts. Ensure the ordering suffix matches the required packaging format, as the standard -TP designation indicates Tape & Reel packing containing 3000 pieces per reel. Confirm RoHS compliance status based on specific order requirements.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for space-constrained designs. The SOT-523 package offers a small footprint suitable for high-density PCB layouts. Consider the 2.2 kΩ input resistance and 250 MHz transition frequency for compatibility with specific signal frequencies and drive levels.

Part Context

This part belongs to the DTC123 series of pre-biased transistors from Micro Commercial Components. The series includes various resistor values and polarity options packaged in different form factors such as SOT-23 and SC-70. The DTC123JE specifically denotes the NPN variant with defined internal resistor ratios housed in the SOT-523 case.

Replacement Considerations

Direct substitutes must match the NPN polarity, SOT-523 package, and similar electrical ratings. Verify equivalent R1 and R2 values if precise biasing characteristics are critical. Cross-reference with other manufacturers offering digital transistors in the same package family.
