| Market Reality | The 2P4M is the little SCR of appliance and small-charger circuits: touch lamps, fan controllers, dimmers, battery chargers and protection latching. The original NEC part is obsolete at the source, and the market is now full of second-source 2P4M markings from numerous fabs - which is generally fine for voltage and current, but the parameter these circuits live on is gate sensitivity: the 2P4M triggers in the microamp range, and a generic "2A/400V thyristor" with a heavier gate simply will not fire in a touch circuit or dimmer designed around it. | - |
