PBSS5250XZ

Single Bipolar Transistors Overview

The PBSS5250X is a PNP low VCEsat transistor manufactured by Nexperia, housed in a SOT89 (SC-62) flat lead Surface-Mounted Device plastic package. It supports a collector current of -2 A and withstands collector-emitter voltages up to -50 V. The device features a minimum DC current gain of 200 at -0.1 A and achieves a typical saturation voltage of -380 mV at -2 A. Thermal resistance from junction to ambient is 225 K/W in free air, reducing to 80 K/W on an FR4 PCB with a standard footprint.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for improved efficiency
• High collector current capability supporting continuous and peak loads

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and manufacturing site codes. Ensure that the selected variant matches the required surface-mount specifications for your assembly process. Cross-reference the part number with the latest product data sheet to confirm availability status and any recent revisions to the electrical characteristics or pinning configuration.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high-efficiency power management with compact layout constraints. The low saturation voltage minimizes heat generation, making it suitable for space-limited environments. Consider the thermal resistance values provided for different mounting conditions to ensure proper heat dissipation. Verify that the operating temperature range meets the environmental requirements of the target application.

Single Bipolar Transistors Part Context
