Single Bipolar Transistors Procurement Notes

Verify the specific suffix KT146 against official Rohm documentation to confirm the exact taping specification and reel quantity. Ensure the ordering code matches the required packaging format, as variations exist between tape-and-reel and cut-tape options. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a compact PNP transistor with moderate current handling is required. The 200mW power dissipation limits its use in high-power scenarios. Verify that the -30V collector-emitter voltage rating aligns with the circuit's maximum supply voltage. Consider the SMT3 package constraints for PCB layout and thermal management requirements during the design phase.

Single Bipolar Transistors Part Context

This part belongs to Rohm's general-purpose discrete transistor lineup designed for surface-mount assembly. It serves as a standard replacement for legacy through-hole components in modern miniaturized electronic devices. The SMT3 package provides a balance between electrical performance and space efficiency for portable equipment.

Single Bipolar Transistors Replacement Considerations

Cross-reference with 2SB1198KT146Q for higher voltage ratings or 2SA1036KT146 for similar PNP characteristics. Verify pinout compatibility and ensure the substitute meets the same thermal and electrical specifications.
