Product Description
Product Overview
DTA144T series are PNP digital transistors with built-in bias resistors, designed for simplified inverter and switching circuit configurations. These transistors eliminate the need for external input resistors, streamlining circuit design. Featuring thin-film resistors with complete isolation, they support negative biasing and minimize parasitic effects. They are ideal for switching, inverter, interface, and driver circuits. Complementary NPN types are available in the DTC144T series. These products are Lead-Free and RoHS Compliant.Product Attributes
- Brand: ROHM
- Type: PNP Digital Transistor (Bias Resistor Built-in Transistor)
- Certifications: Lead Free/RoHS Compliant
