Overview
The DTA143EEBTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -50mA. The device includes two integrated resistors: an input resistor (R1) and an emitter-base resistor (R2), both typically valued at 10kΩ. Key electrical parameters include a DC current gain (hFE) of 35 minimum at 5mA/10V, a saturation voltage of 150mV maximum at 500µA/5mA, and a transition frequency of 250MHz. Power dissipation is rated at 150mW, housed in an EMT3F (SOT-416FL) surface-mount package.
Feature Summary
- Integrates biasing resistors to eliminate external components for inverter circuits
- Simplifies design by requiring only on/off condition settings
- Provides high-speed switching capability suitable for interface applications
Applications
- Inverter circuits
- Interface logic level shifting
- Driver stages for low-current loads
Procurement Notes
Verify the specific suffix BTL against the manufacturer's official datasheet to confirm the EMT3F packaging and tape-and-reel configuration. Ensure compatibility with RoHS3 standards if required by the target assembly process. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a PNP digital transistor with 10kΩ internal biasing resistors is required. It is suitable for applications needing -50V blocking voltage and -50mA output current. Compare hFE and Vce(sat) specifications against load requirements. Consider the SOT-416FL footprint constraints during PCB layout planning.
Part Context
This part belongs to the DTA1xx series of pre-biased PNP transistors from Rohm. It complements the DTC1xx NPN series for push-pull or complementary configurations. The EMT3F package offers a compact solution for space-constrained designs compared to larger through-hole alternatives.
Replacement Considerations
Direct substitutes may include DTA143EETL (EMT3 package) or DTA143ZU3T106 (SOT-323 package) if pinout and thermal characteristics are compatible. Verify resistor values and hFE ranges match the original design requirements before substitution.
