Overview
The DTC144VUAT106 is a single NPN pre-biased bipolar transistor manufactured by ROHM Semiconductor. It features an integrated base resistor network within a compact UMT3 (SOT-323) surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (Ic) of 30 mA, and a maximum power dissipation (Pd) of 200 mW. The device supports a transition frequency of 250 MHz and operates at temperatures up to +150°C.
Feature Summary
- Integrates bias resistors to simplify circuit design and reduce component count
- Optimized for high-speed switching applications with a 250 MHz transition frequency
- Compact UMT3 package suitable for space-constrained surface-mount designs
Applications
- General-purpose signal switching in consumer electronics
- Driver circuits for low-current loads
- Logic interface level shifting
Procurement Notes
Verify the specific suffix 'VUA' against the official ROHM datasheet to confirm the exact pinout and internal resistor configuration. Ensure the selected variant matches the required 30 mA current rating rather than higher-capacity models like the 100 mA variants. Confirm RoHS compliance status for the specific production batch before integration.
Selection Notes
Select this component when a small form factor is critical and the load current does not exceed 30 mA. Compare against standard discrete BJT plus resistor networks to evaluate board space savings. Consider the 50 V breakdown voltage limit for application compatibility. Verify thermal management requirements given the 200 mW power dissipation limit in the SOT-323 package.
Part Context
