Overview
The DTC023YUBTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector current of 100 mA and a supply voltage up to 50 V. The device incorporates an input resistance (R1) ranging from 1 kΩ to 2.2 kΩ and an emitter-base resistance (R2) between 1 kΩ and 10 kΩ. Power dissipation is rated at 0.2 W, with a DC current gain (hFE) of 33 or more. Packaged in the UMT3F (SOT-323FL) surface-mount format measuring 2.1x2.0 mm, it supports a storage temperature range of -55°C to 150°C.
Feature Summary
- Integrates biasing resistors internally to enable inverter circuit configuration without external input components.
- Provides simplified operation by requiring only on/off condition settings for control.
- Utilizes a compact UMT3F surface-mount package suitable for space-constrained designs.
Applications
- General-purpose switching circuits
- Inverter logic configurations
- Digital signal interface buffering
Procurement Notes
Verify the specific ordering suffix, such as TL for taping, against the required packaging quantity of 3000 units. Confirm RoHS compliance status and ensure the component meets the intended environmental specifications before integration into the final assembly process.
Selection Notes
Select this component when a compact NPN digital transistor with moderate gain is required. Ensure the application voltage does not exceed 50 V and the current remains within the 100 mA limit. Verify that the internal resistor values align with the driving source requirements for the specific logic family being used.
Part Context
This part belongs to the DTC023 series of pre-biased transistors from ROHM. It serves as a standard discrete solution for replacing multiple discrete components, reducing board space and assembly complexity. The UMT3F package offers a small footprint compared to traditional through-hole alternatives.
Replacement Considerations
The DTC123YUB is listed as a similar specification replacement option. Verify pin compatibility and electrical parameters before substitution. Note that the DTC123YUB may have different supply status constraints regarding new designs.
