DTC124EE3HZGTL

Overview

The DTC124EE3HZGTL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates biasing resistors with R1 equal to R2 at 22 kOhms each, forming a potential divider configuration. Key electrical parameters include a maximum collector-emitter voltage of 30 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 56 at 5 mA and 5 V, with a transition frequency of 250 MHz. It operates within a temperature range up to +150°C and complies with AEC-Q101 automotive standards.

Feature Summary

• Integrates built-in biasing resistors (R1=R2=22kΩ) to simplify circuit design by eliminating external input resistors for inverter configurations.
• Complies with AEC-Q101 automotive grade reliability standards for high-temperature operation up to +150°C.
• Utilizes compact SOT-416 (EMT3) surface-mount packaging suitable for space-constrained applications.

Applications

• Automotive electronic circuits requiring high-reliability digital switching components.
• Inverter circuits where external base resistors are omitted to reduce component count.
• General-purpose digital logic interfacing and level shifting in consumer electronics.

Procurement Notes

Verify the specific suffix 'HZGTL' against official ROHM documentation to confirm automotive qualification status and tape-and-reel specifications. Ensure compatibility with SOT-416 footprint requirements during PCB layout. Cross-reference datasheet revisions to confirm parameter consistency, particularly regarding thermal resistance and maximum ratings.

Selection Notes

Select this component when an NPN digital transistor with equal internal biasing resistors (22kΩ) is required for automotive or high-reliability applications. Compare hFE minimums and saturation voltages against alternative SOT-416 devices if specific gain or voltage drop constraints exist. Verify that the 100mA collector current and 30V breakdown voltage meet the target circuit's operational limits.

Part Context

This part belongs to the ROHM DTC124 series of Bias Resistor Built-in Transistors (BRBTs). The 'E' designation typically indicates the resistor ratio configuration (R1=R2), while 'HZGTL' specifies the automotive-grade variant and packaging format. It complements PNP counterparts like the DTA124 series within the same family.

Replacement Considerations

Direct substitutes must match the NPN polarity, SOT-416 package, and 22kΩ/22kΩ resistor ratio. Verify equivalent AEC-Q101 compliance if automotive use is intended. Check for identical hFE and VCEO specifications to ensure functional parity in existing designs.
