Type 836 is an American high voltage half wave rectifier. The maximum peak inverse voltage on the anode is 5,000 Volts and the peak cathode current is 1,000 mA.

The anode is treated to aid heat loss by radiation and the filaments run through two cylindrical channels formed from the folded anode sheet. The insulators are ceramic as is to be expected in high voltage devices and by taking the anode to the top cap the maximum separation is achieved in the external circuit between anode and cathode.

The classic envelope is 56 mm in diameter and, excluding the UX4 base pins, is 149 mm tall.
