DTC114YM-TP

Overview

The DTC114YM-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates an NPN bipolar junction transistor with built-in biasing resistors in a compact SOT-323 surface-mount package. The device features a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Internal resistor values are typically 10 kOhms for both the base (R1) and emitter (R2) connections, providing a resistance ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 68, a transition frequency of 250 MHz, and a power dissipation rating of 200 mW. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates NPN transistor with dual internal biasing resistors to reduce external component count.
• Designed for high-speed switching applications with a 250 MHz transition frequency.
• Automotive-grade qualification compliant with AEC-Q101 standards.

Applications

• General-purpose switching circuits
• Driver circuits for logic interfaces
• Level shifting between different voltage domains

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm package type and automotive qualification status. Distributor listings may vary in accuracy regarding the exact physical footprint and RoHS compliance details. Cross-reference the manufacturer datasheet for precise ordering information before procurement.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Ensure the 10 kOhm internal resistance matches the driving source requirements. Verify that the SOT-323 package dimensions fit the PCB layout constraints and that the thermal dissipation capabilities meet the application's power load.

Part Context

This part belongs to the DTC114 series of pre-biased transistors from Micro Commercial Components. The series offers various configurations including PNP and NPN types with different resistor ratios and packages. The YM variant specifically denotes the NPN configuration with 10k/10k resistors in the SOT-323 package.

Replacement Considerations

Direct substitutes include other NPN digital transistors with identical 10k/10k resistor ratios and SOT-323 packaging, such as the DTC114EUA or equivalent parts from other manufacturers like ROHM or ON Semiconductor, provided pinouts and electrical ratings match.
