Who is the Transistor as a Switch poster for?

Transistor as a Switch belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning electronics can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Transistor as a Switch poster?

Work through it before switching any relay, motor or heater from a logic pin. A wall chart earns its place by being glanceable from where the work is happening, so Transistor as a Switch belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Transistor as a Switch?

BJT Operating Regions, BJT vs MOSFET and Common-Emitter Amp sit alongside Transistor as a Switch in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.

Is the Transistor as a Switch poster free to download and print?

Yes. Transistor as a Switch downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.

What size does the Transistor as a Switch poster print at?

Transistor as a Switch is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Transistor as a Switch loses nothing.

Transistor as a Switch — free printable poster

Transistor as a Switch — printable engineering wall chart from LearnPosters. Free vector PDF, US Letter and A4.

Transistor as a Switch, step by step

A half-on transistor dissipates far more than a fully on one.

Work out the load currentSupply divided by load resistance, plus any inrush at the moment of turn-on.
Drive it hardFor a BJT set I_B near I_C/10; for a MOSFET take the gate to the full rail.
Check conduction lossV_CE(sat) × I_C for a bipolar part, I² R_DS(on) for a MOSFET.
Check switching lossVoltage and current overlap during each edge, times the switching rate.
Clamp inductive kickA flyback diode across a relay or motor coil catches the reverse spike.

Educational reference. Switching anything on the mains side is regulated work needing qualified supervision and local compliance.
