The CV4057 is a rugged high voltage half wave rectifier. The CV371 was the predecessor to this rectifier and the CV4042 is the same valve but with flying leads.In operation this valve can withstand a PIV of 5,000 Volts. The maximum reservoir capacitor value is 1.1 µF and a minimum effective series resistance of 4500 Ohms is required. The peak anode current is up to 180 mA.This was also made with flying leads for direct wiring in to a circuit.The thin glass tube envelope is 18 mm in diameter, and excluding the B7G base pins, is 28 mm tall.References: Data-sheet & 1040. Type CV4057 was first introduced in 1958. |
