OZ4

Full-Wave Cold-Cathode Gas Rectifier Tube, High-Aeronautical Shock Ceramic and Glass Envelope Outer Casing Layer, Standard 8-Pin Octal Base Interface Pin Array, Non-Volatile Dual-Anode Gas Discharge Ionization Matrix, Low 15V Typical Operational Tube Drop Voltage, 75mA Maximum Continuous Rectified DC Output Current, High 1000V Peak Inverse Voltage (PIV) Maximum Insulation Limit, Precision Vibrator Power Supply Filtering Switch, Vintage Communications and Instrumentation Interface Routing Link | Vintage instrumentation and early automotive-grade thermionic cold-cathode gas-filled full-wave power rectifier diode tube manufactured by RCA (Radio Corporation of America) under foundational industry tracking code OZ4 (universally logged across vacuum tube registers as 0Z4). Engineered specifically to operate without an active heated filament line—thereby eliminating dedicated heater current draw entirely—this unique device uses an internal ionic gas discharge grid to trigger instant full-wave rectification. It acts as an automated high-voltage AC-to-DC smoothing branch, handling incoming power paths across early tube-driven car radios, mobile tactical field transceivers, and laboratory equipment power supplies cleanly without localized component thermal fatigue loops. | Industry Exact Equivalents: RCA OZ4, RCA 0Z4, RCA 0Z4 Tube | Industry Functional Cross-References: 0Z4G (Glass version), 0Z4-GT, Raytheon 0Z4, Sylvania 0Z4, GE 0Z4, Tung-Sol 0Z4 | Military Specification National Stock Number (NSN): 5960-00-163-5471 (Base 0Z4 Rectifier Tube Matrix Grid)
