Overview
The DTC614TKT146 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SMT3 (SOT-323) surface-mount package. It integrates a bias resistor network to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of 20 V and a continuous collector current of 600 mA. The device features a typical input resistance of 10 kOhms and a minimum DC current gain (hFE) of 820 at 50 mA and 5 V. It supports a maximum operating frequency of 150 MHz with a power dissipation rating of 200 mW and a maximum operating temperature of +150°C.
Feature Summary
- Integrates built-in bias resistors to reduce external component count and PCB space.
- High current capability suitable for driving moderate loads directly.
- Optimized for high-speed switching applications with defined transition frequencies.
Applications
- General-purpose signal switching in consumer electronics.
- Interface circuits between microcontrollers and peripheral devices.
- Driver stages for low-power logic gates or LED indicators.
Procurement Notes
Verify the specific suffix T146 to confirm the SOT-323 packaging and tape-and-reel quantity. Cross-reference the manufacturer part number against official datasheets to ensure compatibility with existing board layouts. Confirm RoHS compliance status through the supplier's certification documents before integration into regulated products.
Selection Notes
Select this component when a 20 V breakdown voltage and 600 mA current capacity are required in a compact SOT-323 footprint. Compare the 10 kOhm input resistance against other variants if different drive currents are needed. Ensure the thermal management plan accommodates the 200 mW power dissipation limit under expected load conditions.
Part Context
This part belongs to ROHM's DTC614 series of pre-biased NPN transistors. The series offers various input resistance values and packaging options to suit different design constraints. The T146 suffix specifically denotes the SOT-323 package configuration used in this variant.
Replacement Considerations
Direct substitutes within the same series include DTC614ZKT146 and DTC614ETA. Verify that alternative packages like SOT-23-3 maintain pinout compatibility if physical space allows for minor layout adjustments.
