Overview
The DTC114YUA is an NPN digital transistor in a SOT-323 package, featuring built-in thin-film bias resistors for simplified circuit design. Key electrical parameters at 25°C include a supply voltage (VCC) of 50 V maximum and input voltage (VIN) of 40 V maximum. The device supports an output current (IO) of up to 70 mA and collector current (IC) of 100 mA, with power dissipation rated at 200 mW. Typical characteristics include an input resistance (R1) of 10 kΩ, a resistance ratio (R2/R1) of 4.7, and a transition frequency (fT) of 250 MHz. It operates within a junction temperature range of -55°C to 150°C.
Feature Summary
- Built-in bias resistors enable inverter circuit configuration without external input resistors
- Thin-film resistors provide complete isolation allowing negative biasing of the input
- Eliminates parasitic effects for simplified on/off condition operation
Applications
- Inverter circuits requiring integrated biasing
- Switching applications with simplified design requirements
- Digital logic interface circuits
Procurement Notes
Verify the part marking '64' against the datasheet to confirm authenticity. Ensure the ordering suffix matches the required RoHS compliance status, as indicated by specific packaging notations. Confirm moisture sensitivity level 1 classification if lead-free finish is required for assembly processes.
Selection Notes
Select this component when space constraints favor the SOT-323 package over larger alternatives. Consider the 10 kΩ typical input resistance and 4.7 resistance ratio for bias network compatibility. Verify that the 50 V supply voltage rating meets the system's maximum operating conditions.
Part Context
This device belongs to Micro Commercial Components' series of NPN digital transistors designed for compact switching applications. The DTC114YUA variant specifically integrates thin-film resistors to reduce external component count. It is manufactured under Rev.3-4-12012020 specifications.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the source material. Cross-referencing should be performed based on matching pinout, electrical ratings, and package dimensions using independent manufacturer databases.
