IPC-7351B Naming Convention for Small Outline Transistors SOT143 and SOT343 Reverse Mount

SOT + Pitch + P + Lead Span Nominal X Height – Pin Qty

Example:

SOT130P210X110R-4N_SOT343_Reverse

SOT = Surface Mount Plastic Small Outline Transistor
130P – Pitch = 1.30mm
210 – Lead Span Nominal = 2.10mm
110 – Component Height (Body Height) = 1.10mm
R – Reverse
4 – Pins Qty = 4
SOT343_Reverse – Standard Package Name (Added by PCB-3D.com)
