DTC143ZMFHAT2L

Overview

The DTC143ZMFHAT2L is an NPN digital transistor from ROHM Semiconductor, featuring built-in bias resistors in a compact SOT-723 (VMT3) package. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes an input resistor R1 of 4.7 kΩ and an emitter-base resistor R2 of 47 kΩ. It has a power dissipation rating of 0.15 W and a DC current gain (hFE) of at least 80. Qualified to AEC-Q101 standards for automotive applications, it supports a storage temperature range from -55°C to +150°C.

Feature Summary

• Built-in bias resistors enable simple inverter circuit configuration without external components.
• Automotive grade qualification ensures high reliability under strict environmental conditions.
• Compact surface-mount packaging facilitates efficient PCB layout.

Applications

• Inverter circuits
• Interface driver stages
• Automotive electronic control units

Procurement Notes

Verify the specific suffix HHA against official documentation to confirm package type and tape/reel specifications. Confirm AEC-Q101 compliance status directly with the manufacturer or authorized distributors before integration into safety-critical designs. Ensure component authenticity through verified supply chain channels.

Selection Notes

Select this component when a single NPN digital transistor with a 4.7kΩ input resistor and 47kΩ emitter-base resistor is required. It is suitable for space-constrained designs needing automotive-grade reliability. Compare hFE requirements and power dissipation limits against other SOT-723 variants if thermal management is critical.

Part Context

This part belongs to the DTC143 series of pre-biased transistors. It shares the same internal resistance values as the standard DTC143ZE but utilizes the smaller SOT-723 package. The HHA suffix typically denotes the specific tape and reel packaging format used for automated assembly processes.

Replacement Considerations

DTC143ZE3TL offers identical electrical characteristics in a larger SOT-416 package. DTC143TMHZGT2L provides similar functionality in the same SOT-723 form factor but may have different packaging quantities. Verify pinout compatibility and physical dimensions before substitution.
