DTC143ZE3TL

Overview

The DTC143ZE3TL is an NPN digital transistor from the ROHM DTC143Z series, housed in a SOT-416 (EMT3) surface-mount package. It integrates bias resistors with R1 at 4.7 kΩ and R2 at 47 kΩ to simplify circuit design. Key electrical parameters include a supply voltage (VCC) of 50 V, a maximum collector current (IC) of 100 mA, and a power dissipation (PD) of 150 mW. The device features a DC current gain (GI) of 80 and a transition frequency (fT) of 250 MHz. It operates within a junction temperature range up to 150°C and is supplied in tape-and-reel packaging.

Feature Summary

• Built-in bias resistors enable inverter circuit configuration without external input resistors.
• Simplified circuit design requiring only on/off condition settings for operation.
• Complementary PNP types available in the DTA143Z series.

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and taping specifications. Confirm RoHS compliance status and long-term availability plans directly with authorized distributors or the manufacturer before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for standard electronic equipment. Ensure the 50V supply voltage and 100mA current ratings align with the target application requirements. Verify that the SOT-416 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the DTC143Z series of bias resistor built-in transistors manufactured by ROHM Semiconductor. The series offers various package options including SOT-723, SOT-323, and SOT-346 to accommodate different space and performance needs across consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the DTC143Z family such as DTC143ZE3 or other variants with identical R1/R2 ratios. Verify pinout compatibility and electrical characteristics like VCEO and IC before substituting.
