Overview
The DTA114WETL is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an EMT3 (SOT-416) surface-mount package. It integrates bias resistors with a typical input resistance of 10 kOhms and an emitter-base resistance of 4.7 kOhms. The device supports a collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with power dissipation rated at 150 mW. It features a maximum operating frequency of 250 MHz and a minimum DC current gain of 24 at 10 mA. The component operates within a temperature range up to +150°C and is supplied in tape-and-reel packaging.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Provides high-speed switching capability suitable for applications requiring fast response times.
- Offers low saturation voltage for efficient power management in digital logic interfaces.
Applications
- General-purpose digital switching circuits

Procurement Notes
Verify the specific suffix configuration against the latest manufacturer datasheet to ensure compatibility with required electrical parameters. Confirm RoHS compliance status and check for any obsolescence notices, as this part may be marked as not recommended for new designs. Ensure ordering quantities align with standard reel sizes.
Selection Notes
Select this component when a compact PNP digital transistor with integrated biasing is required for space-constrained designs. Verify that the 100 mA current rating and 50 V voltage limit meet the application's load requirements. Consider the SOT-416 footprint constraints during PCB layout planning.
Part Context
This component belongs to the DTA114 series of pre-biased transistors from ROHM Semiconductor. These devices are designed to replace discrete resistor-transistor combinations, offering a standardized solution for digital switching tasks. The series is widely used in consumer electronics and industrial control systems where board space is limited.
Replacement Considerations
Publicly confirmed substitute part numbers include PDTA114YM from Nexperia USA Inc. Verify pinout compatibility and electrical parameter equivalence before substitution.
