DTA143XE3TL

Overview

The DTA143XE3TL is a PNP Bias Resistor Built-in Transistor (Digital Transistor) from the ROHM DTA143X series, housed in an EMT3 (SOT-416) surface-mount package. It integrates internal biasing resistors with R1 at 4.7 kΩ and R2 at 10 kΩ to simplify circuit design. The device supports a maximum collector current of -100 mA and a supply voltage of -50 V. Key electrical characteristics include a DC current gain (GI) of 30 minimum at -10 mA output, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW.

Feature Summary

• Built-in biasing resistors eliminate the need for external input components, enabling direct configuration of inverter circuits.
• Simplified operation requires only on/off condition settings, reducing complexity in circuit design.
• High-speed switching capability supported by a transition frequency of 250 MHz.

Applications

• Inverter circuits
• Interface logic applications
• Driver stages

Procurement Notes

Verify the specific suffix 'E3' against the manufacturer's latest documentation to confirm the exact packaging format and tape specifications. Confirm RoHS compliance status and ensure the component meets the required storage temperature range of -55°C to +150°C before integration into the final assembly process.

Selection Notes

Select this component when a compact PNP digital transistor solution is required for low-power switching applications. Ensure the -50V supply voltage and -100mA current limits align with the system requirements. Consider the complementary NPN type, DTC143X series, if a matched pair is needed for push-pull configurations.

Part Context

This part belongs to the DTA143X series of digital transistors manufactured by ROHM Semiconductor. The series offers various package options including SOT-723, SOT-323, and SOT-346, providing flexibility for different board space constraints while maintaining consistent electrical performance across the family.

Replacement Considerations

The DTC143X series serves as the complementary NPN counterpart within the same product family. Verify pinout compatibility and electrical symmetry if substituting or pairing with other devices in the DTA/DTC series.
