Cytat: The DMV32A (for 38kHz sets) and DMV32B (for 56kHz) use the popular and well proven 1500V/6A DTV32A/B damper diodes, while the modulation diode in each case is an ultrafast SSTB506D Turboswitch? diode. Designed for high pulsed current operation, this 600V/5A diode has 95ns maximum reverse recovery time and a forward voltage drop of just 1.2V, as well as soft switching for low noise operation..
