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

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

Example:

SOT192P230X122-4N_JEDEC_TO-253_SOT143

SOT = Surface Mount Plastic Small Outline Transistor
192P – Pitch = 1.92mm
230 – Lead Span Nominal = 2.30mm
122 – Component Height (Body Height) = 1.22mm
4 – Pins Qty = 4
JEDEC_TO-253_SOT143 – Standard Package Name (Added by PCB-3D.com)
