DTC143TE3HZGTL

Overview

The DTC143TE3HZGTL is an NPN digital transistor manufactured by ROHM Semiconductor, housed in a compact SOT-416 (EMT3) surface-mount package. This component integrates a single bias resistor (R1) with the transistor to simplify circuit design. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The typical input resistance is 4.7 kOhms, and the device supports a maximum operating frequency of 250 MHz. It features a minimum DC current gain (hFE) of 100 at 1 mA and 5 V, with a power dissipation rating of 150 mW. The unit operates within a temperature range up to +150°C.

Feature Summary

• Integrates a built-in bias resistor to eliminate external components for inverter circuits
• Utilizes thin-film resistors for complete isolation and minimal parasitic effects
• Simplifies design by requiring only on/off condition settings for operation

Applications

• Inverter circuits
• Interface drivers
• General-purpose driver applications

Procurement Notes

Verify the specific suffix HZGTL against the manufacturer's datasheet to confirm packaging details such as reel size or tape width. Ensure the ordering quantity aligns with the factory packing quantity of 3000 units if purchasing in bulk. Confirm RoHS compliance status directly from the official documentation before finalizing procurement plans.

Selection Notes

Select this component when a single-resistor NPN digital transistor is required for space-constrained designs. The SOT-416 package offers a small footprint suitable for high-density PCB layouts. Consider the 4.7 kOhm input resistance value to ensure compatibility with the driving logic levels and impedance requirements of the upstream control circuitry.

Part Context

This part belongs to the DTC143 series of digital transistors from ROHM Semiconductor. The series includes various configurations with different resistor values and packages. The TE3 variant specifically denotes the SOT-416 package with a single built-in resistor. It is designed for automotive and industrial applications requiring high reliability and simplified biasing networks.

Replacement Considerations

Direct pin-compatible alternatives may include other NPN digital transistors with similar VCEO and Ic ratings. Verify that any substitute maintains the same R1 value and package dimensions. Check for equivalent hFE characteristics and thermal performance to ensure circuit functionality remains unchanged.
