DTC114TKA-TP

Overview

The DTC114TKA-TP is an NPN pre-biased digital transistor manufactured by Micro Commercial Components. It integrates a single NPN transistor with built-in bias resistors, specifically R1 and R2, both rated at 10 kOhms. The device features a maximum collector-emitter voltage (Vceo) of 50 V and a continuous collector current of 100 mA. It operates with a transition frequency of 250 MHz and has a maximum power dissipation of 200 mW. The component is housed in a SOT-23 surface-mount package and supports a maximum operating temperature of +150°C.

Feature Summary

• Integrates NPN transistor with dual 10 kOhm bias resistors for simplified circuit design
• Supports high-speed switching applications with a 250 MHz transition frequency
• Provides robust electrical isolation with 50 V collector-emitter breakdown voltage

Applications

• Inverter circuits requiring integrated input biasing
• High-frequency signal switching and logic level translation

Procurement Notes

Verify the specific suffix 'TP' confirms the lead-free and RoHS-compliant status as documented by MCC. Ensure the ordering part number matches the exact SOT-23 package variant required for your PCB footprint. Cross-reference the datasheet revision date to confirm current electrical characteristics and packaging specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN solution with fixed 10 kOhm base and emitter resistors is needed. It is suitable for designs prioritizing space efficiency over adjustable gain parameters. Consider the 200 mW power dissipation limit and 100 mA current rating against your specific load requirements to ensure reliable operation within thermal constraints.

Part Context

This part belongs to the DTC114 series of pre-biased transistors from Micro Commercial Components. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs. The series includes various resistance values and packages, with the TKA variant specifically denoting the 10k/10k configuration in a SOT-23 housing.

Replacement Considerations

Direct substitutes include other DTC114 series parts from different manufacturers offering identical 10k/10k NPN configurations in SOT-23 packages. Verify pinout compatibility and thermal performance metrics when cross-referencing with alternative suppliers to ensure functional equivalence.
