Diode (NOT rectifier) ·Diode-Diode
Special-quality double diode with separate cathodes and internal screening, designed for statistically controlled performance under severe vibration and shock.
Special-quality double diode with separate cathodes and internal screening for vibration- and shock-resistant equipment.
General specifications
Properties common to every published source and operating point.
Electrical assignments shared by every tube using this base designation.
No verified pinout is recorded for this base designation.
2 physical sections, each with unique specifications.
Section 1
Promoted values taken from published characteristics and absolute/limiting ratings.
Section 2
Physical diode section added during approved section-structure reconciliation.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
