DTA124EETL

Overview

The DTA124EETL is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an EMT3 (SOT-416) surface-mount package. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 30 mA. The device includes integrated resistors R1 and R2, both typically valued at 22 kOhms, resulting in a resistance ratio of approximately 1. Key electrical parameters include a minimum DC current gain (hFE) of 56 at 5 mA and 5 V, a maximum transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The saturation voltage is specified at 300 mV under standard test conditions.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external components for inverter configurations.
• Provides high-speed switching capabilities suitable for interface and driver applications.
• Offers compact surface-mount packaging for efficient board space utilization.

Applications

• Interface circuits requiring signal inversion or buffering.
• Driver stages for low-power logic interfaces.
• General-purpose switching applications in consumer electronics.

Procurement Notes

Verify the specific suffix 'ETL' corresponds to the EMT3 package and cut-tape/reel availability from authorized distributors. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to procurement. Ensure the ordering quantity matches the supplier's minimum order requirements and packaging formats such as cut tape or reel.

Selection Notes

Select this component when a PNP digital transistor with 50 V breakdown and 30 mA current capacity is required in an EMT3 package. Compare against complementary NPN types like the DTC124E series for balanced designs. Verify that the 22 kOhm internal resistor values align with the target input impedance and drive strength requirements of the application circuit.

Part Context

The DTA124EETL belongs to the broader DTA124 family of pre-biased PNP transistors offered by ROHM. This series provides standardized solutions for replacing discrete resistor-transistor combinations. The ETL suffix specifically denotes the EMT3 surface-mount package variant, distinguishing it from other form factors like SOT-23 or UMT3F found in related part numbers within the same product line.

Replacement Considerations

Direct substitutes may include other ROHM PNP digital transistors in the EMT3 package with similar electrical ratings, such as the DTA124XE3HZGTL if higher voltage tolerance is acceptable. Cross-reference with generic equivalents only if pin compatibility and electrical specifications match exactly.
