DTA024XEBTL

Overview

The DTA024XEBTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a maximum collector current of -100mA. The device incorporates an input resistor (R1) of 10kΩ and an emitter-base resistor (R2) of 47kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 35 and a power dissipation rating of 0.15W. It is housed in the EMT3F surface-mount package, measuring 1.6x1.6mm.

Feature Summary

• Integrated bias resistors eliminate the need for external input components, enabling direct inverter circuit configuration.
• Thin-film resistor construction provides complete isolation, allowing positive input biasing while minimizing parasitic effects.
• Simplified operation requires only on/off condition settings, reducing overall design complexity.

Applications

• Inverter circuits
• Interface logic
• Driver stages

Procurement Notes

Verify the specific suffix 'EBTL' against the manufacturer's official datasheet to confirm the tape-and-reel packaging format and quantity. Ensure the component meets RoHS compliance requirements for the intended application. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for low-power switching applications. The EMT3F package suits space-constrained designs. Verify that the 10kΩ input resistance aligns with the driving source impedance and that the -50V rating exceeds the maximum circuit voltage.

Part Context

This part belongs to Rohm's standard DTA series of digital transistors with built-in resistors. These devices are designed as general-purpose replacements for discrete resistor-transistor combinations. The series offers various resistor ratios and polarity options to accommodate different logic interface needs in consumer and industrial electronics.

Replacement Considerations

Check for compatible substitutes within the same DTA series, such as DTA024EEB or DTA024UEB, which share similar electrical characteristics but may differ in resistor values or package types. Ensure any replacement maintains the PNP polarity and fits the EMT3F footprint if board space is limited.
