NOTES:
1. Pins 3 and 7 tied internally.
2. Fixed resistor may be used and Ebb varied to give desired current.
3. Test to be conducted with the tube exposed to light intensity of 5 to 50 footcandles.
4. This test to be performed at the conclusion of the holding period.
5. This test applies to flexible leads as well as for rigid leads.
6. This specification sheet uses accept on zero defect sampling plan, in accordance with MIL-PRF-1, table III.
