6E5PI high-frequency pulse tetrode, bilingual Russian source. Typical Va 150 V, screen 150 V, plate current >=35 mA, screen current <=18 mA, cathode resistor 30 Ω, gm >=24 mA/V, plate resistance 10 kΩ. Max plate 250 V and screen 250 V; at cutoff (Ik <=5 µA), plate/screen may reach 470 V. Max DC cathode current 100 mA, pulsed cathode current 9 A. IMPORTANT: 3 W is maximum COMBINED plate-plus-screen dissipation, not independent plate dissipation; plate dissipation field intentionally unset. Screen dissipation 2 W maximum. Heater-cathode +100/-150 V, grid1 max negative -100 V. Capacitances input 15±2 pF, output approx 2.5 pF, transfer <=0.075 pF, cathode-heater <=13.5 pF. Pulse emission >=6 A at 6.3 V heater, >=3 A at 5.7 V, at 150 V pulse, 50 Hz, 1–2 µs.
