Procurement Notes
Verify the specific ordering suffix to ensure correct packaging format, as variations exist between reel, cut tape, and MouseReel options. Confirm RoHS compliance status through official documentation before integration. Check supply status regularly, as availability may fluctuate based on production cycles and regional distribution channels.
Selection Notes
Select this component when a PNP digital transistor with a 4.7 kOhm base resistor is required in a compact SOT-323 package. Ensure the application voltage does not exceed -50 V and current requirements remain within -100 mA limits. Consider complementary NPN types like DTC143ZU3HZGT106 if paired configurations are needed for bridge or push-pull topologies.
