Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix required for plating options. The datasheet indicates that adding 'PBFREE' ensures lead-free compliance, while 'TIN/LEAD' specifies tin/lead plating. Confirm the tape and reel quantity matches the 'TR' designation in the model number before finalizing procurement orders to ensure correct packaging format.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN transistor is required in a compact SOT-23 footprint. Ensure the circuit operates within the 300 V collector-emitter limit and 500 mA current constraint. Consider the complementary CMPTA92 PNP device if a matched pair is needed for push-pull configurations. Verify thermal management capabilities given the 357 °C/W junction-to-ambient resistance.

Single Bipolar Transistors Part Context

This part belongs to the CMPTA series of complementary high-voltage transistors from Central Semiconductor Corp. The series includes the CMPTA42 (NPN) and CMPTA92 (PNP) variants. These devices are marketed as surface mount solutions for applications requiring higher voltage ratings than standard small-signal transistors typically provide in the same package type.
