Overview
DTA143XEFRATL is an NPN digital transistor with built-in resistors, designed for surface-mount applications in the EMT3 (SOT-416) package. It features a supply voltage of -50V and a collector current of -0.1A. The internal biasing network consists of an input resistance (R1) of 4.7kΩ and an emitter-base resistance (R2) of 10kΩ. The device supports a power dissipation of 0.15W and operates within a storage temperature range of -55°C to 150°C. It complies with AEC-Q101 automotive standards and is supplied in tape-and-reel packaging with a quantity of 3000 units.
Feature Summary
- Integrates NPN transistor with dual bias resistors to simplify circuit design by eliminating external components.
- Complies with AEC-Q101 qualification standards for automotive electronic equipment reliability.
- Utilizes compact SOT-416 surface-mount package suitable for high-density PCB layouts.
Applications
- Automotive-grade logic interface circuits
- Driver circuits for relays and solenoids
- Level shifting between microcontrollers and peripheral devices
Procurement Notes
Verify the specific suffix FRAT against the manufacturer's official datasheet to confirm the exact taping specifications and reel dimensions. Ensure the component meets the required AEC-Q101 grade for automotive applications. Cross-reference the ordering number DTA143XEFRAT106 with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when an NPN digital transistor with a 4.7kΩ input resistor and 10kΩ emitter-base resistor is required. The SOT-416 package offers a balance of thermal performance and space efficiency. Verify that the -50V collector-emitter voltage rating aligns with the target circuit's maximum operating voltage requirements.
Part Context
The DTA143XE series represents ROHM's standard line of pre-biased transistors. The XE variant specifically denotes the NPN configuration with the defined resistor ratio. This series is widely used in consumer electronics and industrial control systems where simplified biasing networks reduce board space and assembly costs.
Replacement Considerations
DTA143EE3 is listed as a similar level replacement with the same pinout and package, though it lacks AEC-Q101 automotive qualification. Verify electrical parameter compatibility, particularly the hFE gain range and resistor tolerances, before substituting.
