Ediswan 19E2 pulse damping diode, normal short-pulse PIV max 4000 V, exceptional fault-pulse PIV 5500 V only under specified transient condition, max peak forward/anode current 12 A. Typical peak current 10 A, typical anode dissipation 3.5 W, approximate DC resistance 39 Ω at 10 A peak. Heater 4 V 2 A indirectly heated, warm-up 30 seconds before anode voltage. Max bulb temperature 150 °C, vertical mounting, octal IO8 with heater pins 2/7 and CT2 anode top cap. Average rectified current and forward drop not specified; corresponding scalar fields intentionally left null.
