The PZ30 consists of a pair of half wave rectifiers in a single envelope. These could be used for full wave rectification but the design use was with a series heater chain in universal mains applications this suggests the absence of a mains transformer and therefore an absence of the anti-phase anode supplies. The configuration offered the choice of parallel connection directly fed from the mains, or as a voltage doubler. Normally the voltage doubler configuration was used in areas of 110 Volt mains supplies.

The maximum reservoir capacitor was 50 µF and the minimum series resistance had to be 50 Ohms.

The classic envelope is 42 mm in diameter and, excluding the IO base pins, is 105 mm tall.
