DTC123JMFHAT2L

Overview

The DTC123JMFHAT2L is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a maximum collector current of 100 mA and a supply voltage of -50 V. The device includes an internal base resistor (R1) of 2.2 kOhms and an emitter-base resistor (R2) of 47 kOhms. Key electrical parameters include a DC current gain (hFE) minimum of 80 at 10 mA and 5 V, and a transition frequency of 250 MHz. Power dissipation is rated at 150 mW, with a saturation voltage of 300 mV at specific test conditions. It is housed in a VMT3 surface-mount package and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrated bias resistors eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• Automotive-grade reliability certified under AEC-Q101 standards for enhanced durability in vehicle applications.
• Compact VMT3 surface-mount package facilitates high-density PCB layout and automated assembly processes.

Applications

• Automotive electronic control units requiring robust switching capabilities
• General-purpose inverter circuits in consumer electronics

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging quantity and tape-and-reel specifications. Confirm that the component meets the required AEC-Q101 grade if intended for automotive use. Check the latest datasheet for any updates on recommended new designs status or alternative package options. Ensure compatibility with existing BOM requirements regarding pinout and thermal characteristics before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The 2.2 kOhm base resistor value suits standard logic interface applications. Consider the 150 mW power dissipation limit for thermal management planning. Verify that the -50 V supply voltage rating aligns with the target circuit's operational requirements. Compare against complementary NPN variants if both polarities are needed in the same system.

Part Context

This part belongs to the DTA123 series of pre-biased PNP transistors from Rohm Semiconductor. It shares functional similarities with other members of the family but differs in package type and specific electrical tolerances. The VMT3 package distinguishes it from larger SOT-23 or SOT-723 variants. It serves as a direct replacement for legacy discrete resistor-transistor networks in compact digital switching applications.

Replacement Considerations

DTA123JM is a similar PNP digital transistor in the same series. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the replacement part meets the same AEC-Q101 automotive qualification if required for the application.
