Single Bipolar Transistors Applications

• General-purpose signal amplification circuits
• Low-frequency switching applications
• Driver stages for logic interfaces

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TRA' against official datasheets to confirm tape-and-reel packaging status. Ensure RoHS compliance documentation matches the 'PBFREE' designation. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm active production status and availability before procurement.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 40V rating and 800mA capability is required in a through-hole TO-92 package. Consider the 300MHz transition frequency for high-speed switching needs. Evaluate power dissipation limits relative to thermal management requirements in the target application environment.

Single Bipolar Transistors Part Context

This part belongs to the widely used 2N2222A family of general-purpose NPN transistors. Central Semiconductor offers this variant as a lead-free alternative to traditional military or commercial grades. It serves as a direct replacement for legacy designs requiring standard small-signal BJT characteristics in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the 2N2222A and MPS2222A. Verify pinout compatibility and ensure equivalent electrical ratings for voltage, current, and gain are maintained during substitution.
