|---|---|---|---|---|---|
| Each Section | 135 V | 7000 | 280 | 2 | 125 mA |
Application Notes
With fixed bias, the anode circuit should contain a protective resistance to provide a minimum drop of 15V DC. For parallel sections at high dissipation, separate anode and cathode resistors are required.
