Product Description
Product Overview
The DTC144W series are NPN digital transistors featuring built-in biasing resistors, simplifying inverter circuit configurations by eliminating the need for external input resistors. These transistors utilize thin-film resistors with complete isolation, allowing for negative input biasing and eliminating parasitic effects. They are designed for ease of circuit design, requiring only the setting of on/off conditions for operation. Complementary PNP types are available in the DTA144W series. These devices are Lead Free and RoHS Compliant.Product Attributes
- Brand: ROHM
- Certifications: Lead Free/RoHS Compliant
