DTC143ZUBHZGTL

Overview

The DTC143ZUBHZGTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a collector current of -100 mA and a supply voltage of -50 V. The device incorporates an input resistance (R1) of 4.7 kΩ and an emitter-base resistance (R2) of 47 kΩ, maintaining a standard resistor ratio of 10. Packaged in the SOT-323FL (UMT3F) surface-mount format, it supports power dissipation up to 0.2 W and functions within a storage temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual bias resistors (R1=4.7kΩ, R2=47kΩ) to eliminate external components
• Optimized for compact surface-mount applications via SOT-323FL packaging
• Designed for high-reliability automotive-grade environments

Applications

• Automotive interface circuits
• Inverter driver stages
• General-purpose digital switching logic

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Ensure storage conditions remain within specified thermal limits to preserve semiconductor integrity prior to assembly.

Selection Notes

Select this PNP variant when negative logic or high-side switching is required. Compare against NPN equivalents like DTC143ZU3HZGT106 if polarity differs. Verify that the SOT-323FL footprint aligns with existing PCB land patterns and thermal management capabilities.
