DTC143EE3HZGTL

Overview

The DTC143EE3HZGTL is an NPN digital transistor from ROHM Semiconductor, housed in a compact SOT-416 (EMT3) surface-mount package. It integrates bias resistors with R1 and R2 both at 4.7 kΩ, eliminating the need for external input components. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 150 mW. The device features a minimum DC current gain (hFE) of 30 at 10 mA and 5 V, with a transition frequency of 250 MHz. Designed for automotive applications, it complies with AEC-Q101 standards and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual bias resistors (R1=R2=4.7kΩ) to simplify circuit design by removing the need for external input resistors.
• Automotive-grade reliability compliant with AEC-Q101 standards for high-temperature operation up to 150°C.
• Compact SOT-416 surface-mount package facilitates space-efficient PCB layout.

Applications

• Automotive digital logic circuits requiring robust performance under varying thermal conditions.
• Inverter circuits where built-in biasing simplifies the interface between microcontrollers and loads.
• General-purpose switching applications in automotive electronics systems.

Procurement Notes

Verify the specific suffix 'HZGTL' against official ROHM documentation to confirm automotive grade compliance and RoHS status. Ensure the ordering quantity aligns with the standard tape and reel packaging quantity of 3000 units. Cross-reference the manufacturer part number with distributor listings to confirm availability and lead times prior to procurement.

Selection Notes

Select this component when an NPN digital transistor with equal bias resistors (4.7 kΩ) is required for automotive environments. It serves as a direct replacement for non-automotive grades like DTC143EETL if AEC-Q101 certification is mandatory. Consider the 50 V VCEO and 100 mA Ic limits to ensure adequate headroom for the target application's voltage and current requirements.

Part Context

This part belongs to the DTC143 series of bias resistor built-in transistors. The 'EE' designation indicates NPN polarity with equal internal resistors. The 'HZGTL' suffix typically denotes automotive qualification and specific packaging. It complements the PNP counterpart DTA143EE3HZGTL in complementary designs.

Replacement Considerations

The DTC143EETL is a standard commercial grade equivalent but lacks automotive certification. For direct functional substitution without automotive requirements, DTC143EETL may be used. Verify pinout compatibility in the SOT-416 package before replacing.
