Overview
The DTA114EMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an input resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 10 kOhms, providing a typical resistance ratio of 1. It offers a minimum DC current gain (hFE) of 30 at -1 mA and -5 V. The component is housed in a compact SOT-723-3 surface-mount package, dissipates up to 150 mW, and supports a maximum operating temperature of +150°C.
Feature Summary
- Integrates built-in bias resistors (R1=R2=10kΩ) to eliminate external components and simplify circuit layout.
- Provides high reliability through AEC-Q101 automotive grade qualification for demanding environments.
- Features a compact SOT-723 surface-mount package designed for space-constrained applications.
Applications
- Inverter circuits
- Interface drivers
- Automotive electronic control units
Procurement Notes
Verify the specific suffix 'T2L' corresponds to the required tape-and-reel packaging configuration. Confirm that the AEC-Q101 automotive qualification meets the target application's reliability standards. Ensure the SOT-723 footprint matches the PCB design constraints. Check for any end-of-life or not-recommended-for-new-designations if sourcing from secondary markets.
Selection Notes
Select this component when a PNP digital transistor with equal 10kΩ internal resistors is required. It is suitable for applications needing -50V blocking capability and -100mA load current. Consider the SOT-723 package size for board space limitations. Verify thermal dissipation requirements against the 150mW power rating under expected operating conditions.
Part Context
This part belongs to the DTA114 series of digital transistors from ROHM. It serves as the PNP counterpart to NPN variants like the DTC114EM. The series is characterized by integrated biasing networks, reducing component count in switching and logic interface applications.
Replacement Considerations
Direct substitutes include other PNP digital transistors with similar -50V ratings, -100mA current, and 10kΩ/10kΩ internal resistors in SOT-723 packages. Verify pinout compatibility and electrical parameters before substitution.
