Web1 Answer. Sure. Not all manufacturers specify the data for all their BJTs, but there are good data sheets around, for instance the 2SA2090. Page 2 lists the delay times for a specific base current (Ton, Tstg, Tf): Page 3 has a detailed test circuit and shows how to interpret the waveforms obtained using the test circuit: WebOct 25, 2010 · The switching turn-on transitions greatly affect CM noise. Comparing a power MOSFET to a BJT, the MOSFET has much faster switching speed and much shorter turn-on time than the BJT, and therefore generates higher dv/dt and more CM noise. BJT-based solutions directly reduce the sources of EMI noise, such as the switching di/dt …
