2PB1219AR/ZLX

Single Bipolar Transistors Overview

The 2PB1219AR/ZLX is a PNP bipolar junction transistor (BJT) manufactured by NXP. It is housed in an SMD/SMT SOT-323-3 package with dimensions of 2.2 mm length, 1.2 mm width, and 1 mm height. The device supports a maximum collector-emitter voltage (VCEO) of 50 V, a collector-base voltage (VCBO) of 60 V, and an emitter-base voltage (VEBO) of 5 V. It handles a maximum DC collector current of 0.5 A with a gain bandwidth product (fT) of 100 MHz. The DC current gain (hFE) ranges from 40 to 85 depending on the operating point. It operates within a temperature range of -65 °C to +150 °C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix ZLX against official NXP documentation to confirm tape-and-reel specifications and lot traceability. Ensure the ordering part number matches the exact electrical parameters required for the design. Cross-reference the SOT-323-3 footprint with PCB library data. Confirm RoHS compliance status through the manufacturer's latest release notes.

Single Bipolar Transistors Selection Notes

Select this component when a PNP BJT with 50 V VCEO and 0.5 A IC capability is required in a small SOT-323-3 package. Consider the hFE variation between 40 and 85 for biasing calculations. Evaluate the 100 MHz fT for high-speed switching needs. Compare thermal resistance and power dissipation limits against the application's ambient temperature constraints.
