- Utilizes the compact SS-Mini3-F1 surface-mount package suitable for automated tape-and-reel processing.
Applications
- Digital logic interface circuits
- Switching applications in consumer electronics
- General-purpose signal switching
Procurement Notes
Verify availability status as this part is officially discontinued by Panasonic Industry. Confirm that any sourced units are genuine components from authorized distributors or surplus suppliers. Check for RoHS compliance documentation if required for specific manufacturing standards. Ensure the replacement component matches the pinout and electrical characteristics of the original design.
Selection Notes
Select based on the specific resistor ratio of R1/R2 = 4.7. Verify that the -50 V rating and -100 mA current capacity meet the circuit requirements. Consider the thermal performance and power dissipation limits under operating conditions. Ensure the package footprint matches the existing PCB layout constraints.
Part Context
This component belongs to the UNR911xJ series of pre-biased transistors. The 'D' suffix indicates the specific internal resistance configuration (47k/10k). The 'J' denotes the package type and marking code. This series was designed to simplify biasing networks in digital logic interfaces.
Replacement Considerations
Nexperia PDTA144VM is listed as a similar alternative. Verify compatibility regarding resistor values, hFE, and package dimensions before substitution.
