DTA143ZEBTL

Overview

The DTA143ZEBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an SOT-416 (EMT3) surface-mount package. It operates with a collector-emitter voltage of -50 V and a maximum collector current of -100 mA. The device incorporates thin-film resistors with R1 at 4.7 kΩ and R2 at 47 kΩ, providing a DC current gain (hFE) of 80 to 100 at 5 mA and -10 V. It supports a power dissipation of 150 mW and functions across a temperature range from -55 °C to +150 °C.

Feature Summary

• Built-in bias resistors enable inverter circuit configuration without external input components.
• Thin-film resistor technology ensures complete isolation and eliminates parasitic effects.
• Simplified design process by requiring only on/off condition settings for operation.

Applications

• Inverter circuits
• Interface logic
• Driver applications

Procurement Notes

Verify the specific suffix EBTL against the official ROHM datasheet to confirm the exact resistance values and packaging type. Ensure the component meets RoHS compliance requirements for the target assembly. Confirm availability status as active or obsolete before finalizing procurement plans.

Selection Notes

Select this PNP variant when complementary NPN types like the DTC143Z series are required. Verify that the 4.7 kΩ base resistor and 47 kΩ emitter-base resistor ratios suit the specific logic interface needs. Ensure the SOT-416 footprint aligns with the PCB layout constraints.

Part Context

This component belongs to ROHM's standard digital transistor family, designed for replacing discrete resistor-transistor networks. It serves as the PNP counterpart to the DTC143Z series, offering space savings and simplified biasing in compact electronic designs.

Replacement Considerations

The DTC143ZVA is listed as a substitute but utilizes a through-hole IN-LINE package rather than surface mount. Verify pinout compatibility and thermal management differences if transitioning between these form factors.
