Diodes 1. Diodes do not share current very well. If you put two diodes in parallel the one with the lowest impedance at the current you require will hog the current. The second diode will share almost nothing. If the Diodes were identical and were heatsunk together they would share the current equally but in practice this will never happen. You are better off just buying a diode rated at a higher current.
2. NEVER NEVER NEVER put a diode across (in parallel) with a solenoid that is connected to an AC power source. The diode will blow almost instantly. When it blows it may blow open or could short. If it shorts your transformer will have to supply the short circuit current until it decides to trip it's circuit breaker. Diodes are used to snub inductive kickback from inductors (solenoids) when these solenoids are connected to a DC power source. The diode is connected with the stripe (cathode) to the positive and the (anode) to the negative side of the circuit (in parallel with the coil). With Gilbert toys, AC is used on most all solenoid accessories. Do not use diodes in parallel. Sincerely, Robert E.
