Overview
The DTC023EUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates in an SOT-323FL (UMT3F) surface-mount package with three terminals. Key electrical parameters include a supply voltage of 50 V and a collector current of 100 mA. The internal resistor configuration consists of R1 at 2.2 kΩ and R2 at 2.2 kΩ. The device supports a power dissipation of 0.2 W and maintains a minimum DC current gain (hFE) of 20. It functions within a storage temperature range of -55°C to +150°C.
Feature Summary
- Integrates bias resistors internally to eliminate external components for inverter circuits
- Provides simplified on/off control logic through integrated resistance network
- Utilizes compact SMD packaging for efficient board space utilization
Applications
- General-purpose switching applications
- Driver circuits for small-signal loads
- Logic level translation interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging format and tape-and-reel specifications. Confirm RoHS compliance status directly from the latest datasheet revision. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a compact NPN switch with fixed 2.2 kΩ input and emitter-base resistors is required. Ensure the 50 V voltage rating and 100 mA current capacity align with the target load requirements. Verify that the SOT-323FL footprint matches the PCB layout constraints and thermal management needs.
Part Context
This component belongs to ROHM's standard digital transistor series designed for replacing discrete resistor-transistor combinations. It serves as a direct replacement for similar SOT-323 packaged NPN digital transistors with identical resistor ratios. The product line focuses on reducing component count and assembly time in consumer electronics and industrial control systems.
Replacement Considerations
DTC123JUBTL offers a similar NPN configuration but features different resistor values (R1=2.2kΩ, R2=47kΩ). Verify functional compatibility based on specific biasing requirements before substitution.
