Single Bipolar Transistors Procurement Notes

Verify RoHS compatibility status directly with Toshiba sales representatives, as environmental compliance varies by production lot. Confirm that the ordering suffix 'T2F(M' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Ensure design adheres to the derating concepts outlined in the Toshiba Semiconductor Reliability Handbook to maintain long-term operational stability under thermal stress.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high voltage handling capabilities combined with moderate current drive. The 160 V rating provides significant headroom for power supply variations compared to standard 50 V transistors. Consider the complementary 2SA2219 for push-pull configurations to ensure matched performance characteristics. Evaluate the 1 W power dissipation limit against the expected ambient operating conditions to determine necessary heat sinking requirements.

Single Bipolar Transistors Part Context

This part belongs to the Toshiba general-purpose small-signal transistor family utilizing an epitaxial planar process. It serves as a robust alternative for legacy designs requiring higher voltage tolerance than standard audio transistors. The TO-92 form factor allows for easy integration into through-hole PCB layouts commonly found in consumer electronics and industrial control modules.
