PDTB123YUF

Overview

The PDTB123YUF is a PNP Resistor-Equipped Transistor (RET) from the Nexperia PDTB1xxxU series, housed in an SOT323 (SC-70) surface-mount package. It features built-in bias resistors with R1 at 2.2 kΩ and R2 at 10 kΩ, yielding a typical resistor ratio of 4.55. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -500 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 70 at IC = -50 mA and VCE = -5 V, and a transition frequency (fT) of 140 MHz. Thermal performance allows for operation up to a junction temperature of 175 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Qualified for automotive applications under AEC-Q101 standards.
• Designed for high-temperature environments with a maximum junction temperature of 175 °C.

Applications

• IC input control
• Switching loads
• Digital applications in automotive and industrial segments

Procurement Notes

Verify the specific ordering suffix 'U' corresponds to the SOT323/SC-70 plastic surface-mounted package variant. Confirm that the marking code ZK* matches the intended manufacturing site requirements. Ensure the procurement documentation references the correct product data sheet revision for the PDTB1xxxU series to guarantee compliance with the specified electrical parameters and thermal limits.

Selection Notes

Select this component when a PNP transistor with integrated biasing is required for space-constrained designs using the SC-70 footprint. The 2.2 kΩ input resistor value is suitable for standard logic interface levels. Consider the 10 kΩ base-emitter resistor for improved off-state stability. Verify that the -500 mA current rating meets the load requirements and that the 175 °C thermal capability aligns with the operating environment.

Part Context

This part belongs to the PDTB1xxxU series of 50 V, 500 mA PNP resistor-equipped transistors. It serves as the PNP complement to the NPN PDTD123YU model within the same family. The series offers various resistor configurations in the SOT323 package, providing cost-saving alternatives to discrete BC807 or BC817 series transistors in digital switching applications.

Replacement Considerations

The direct NPN complement within the same package and series is PDTD123YU. For general-purpose replacements, verify compatibility with discrete BC807 or BC817 series transistors, noting that discrete components lack the integrated biasing network and may require external resistor adjustments.
