DTA024XUBTL

Overview

DTA024XUBTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors within a UMT3F (SOT-323FL) surface-mount package. The device supports a supply voltage of -50 V and a collector current of -100 mA. It incorporates an input resistance (R1) of 22 kΩ and an emitter-base resistance (R2) of 47 kΩ. Key electrical characteristics include a DC current gain (hFE) ranging from 68 to 560 at specified test conditions, with a maximum power dissipation of 200 mW. The component operates within a storage temperature range of -55°C to +150°C.

Feature Summary

• Integrates PNP bipolar junction transistor with dual internal bias resistors for simplified circuit design.
• Utilizes compact UMT3F surface-mount packaging suitable for space-constrained applications.
• Provides standardized resistor ratios to ensure consistent transistor biasing without external components.

Applications

• General-purpose switching circuits in consumer electronics.
• Driver stages for logic interface applications requiring level shifting.
• Signal processing circuits utilizing pre-biased transistor configurations.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status and availability for new designs, as product lifecycles may affect long-term sourcing options for this component series.

Selection Notes

Select DTA024XUBTL when a PNP configuration with 22kΩ base and 47kΩ emitter resistors is required. Ensure the -50V voltage rating and 100mA current capacity align with the target application loads. Compare thermal performance requirements against the 200mW power dissipation limit in the final assembly environment.

Part Context

This component belongs to Rohm's standard digital transistor lineup, designed to replace discrete resistor-transistor networks. It simplifies PCB layout by integrating biasing elements directly into the semiconductor package, reducing component count and assembly time compared to traditional discrete solutions.

Replacement Considerations

The DTA024XU3 is listed as a similar specification alternative with identical electrical parameters but utilizes a different package variant. Verify mechanical footprint compatibility before substitution.
