DTA024EUBTL

Overview

The DTA024EUBTL 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 -50 V and a continuous collector current of -30 mA. The device includes an input resistor (R1) and an emitter-base resistor (R2), both typically valued at 22 kΩ. Key electrical parameters include a minimum DC current gain (hFE) of 60 at -5 mA and -10 V, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW. It is housed in a UMT3F (SOT-323FL) surface-mount package.

Feature Summary

• Integrated biasing resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• Surface-mount construction in a compact UMT3F package facilitates automated assembly and space-constrained designs.
• High-speed operation capability supports applications requiring rapid switching frequencies up to 250 MHz.

Applications

• General-purpose inverter circuits
• Driver circuits for relays and solenoids
• Logic level shifting and buffering

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging quantities. Ensure storage conditions adhere to moisture sensitivity levels to prevent damage prior to soldering.

Selection Notes

Select this component for PNP logic inversion tasks requiring integrated biasing. Compare hFE requirements against load specifications. Verify that the 22 kΩ internal resistance values align with the driving source's current capabilities. Consider thermal constraints given the 200 mW power dissipation limit in the small outline package.

Part Context

This part belongs to ROHM's standard digital transistor series, which combines bipolar junction transistors with pre-biased resistors. The DTA prefix indicates a PNP configuration, while the EUBTL suffix denotes the specific SOT-323FL package and taping format. It serves as a discrete alternative to complex driver ICs in low-power switching applications.

Replacement Considerations

The DTA024EUBTLDKR and DTA024EUBTLTR are equivalent variants differing only in packaging format (Digi-Reel/Cut Tape vs. Reel). No functional substitutes from other manufacturers are confirmed in the provided documentation.
