DTA123EEFRATL

Overview

DTA123EEFRATL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within a single SC-75A (SOT-416) surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 0.1 A. It includes an internal resistor configuration with a built-in bias resistance ratio of 1.0. Key electrical parameters include a minimum DC current gain (hFE) of 20 and compliance with RoHS standards. The component operates within a standard temperature range and utilizes a plastic/epoxy rectangular small outline package with three terminals.

Feature Summary

• Integrates a PNP bipolar junction transistor with dual bias resistors to simplify circuit design
• Utilizes a compact SMD package for efficient space-saving implementation
• Provides standardized resistance ratios to ensure consistent switching characteristics

Applications

• General-purpose digital switching circuits
• Interface logic level translation
• Driver stages for low-current loads

Procurement Notes

Verify the specific suffix FRATL against the manufacturer's official datasheet to confirm the exact reel quantity and tape specifications. Ensure the ordering part number matches the required packaging format for automated assembly processes. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with a 1:1 bias resistance ratio is required in a SOT-416 package. Confirm that the 50 V voltage rating and 100 mA current capacity align with the target application's electrical demands. Verify compatibility with the intended PCB footprint and soldering thermal profile during the design phase.

Part Context

This part belongs to ROHM's DTA123 series of pre-biased transistors, which integrate resistors directly onto the silicon die or within the package. The series offers various resistance values and packages to accommodate different drive requirements. The EE variant specifically denotes the 1:1 resistance ratio configuration.

Replacement Considerations

Check for direct pin-compatible alternatives within the same series that may offer updated packaging or availability. Verify that any substitute maintains the identical PNP polarity, voltage ratings, and bias resistance ratio to ensure functional equivalence without circuit modification.
