Frequently Asked Questions
What is the maximum allowed operational power dissipation ($P_D$)?
The repetitive peak forward current has a maximum rated power dissipation of 1.0 W, which must be achieved using a printed circuit board.
Are there special or non-standard applications requiring specific advice?
Yes; for specialized uses like aerospace or automotive equipment where high reliability is needed, customers should consult sales staff in advance.
If I test the Zener voltage at a temperature other than 25°C, how must I proceed?
The $V_Z$ value measured at any temperature other than 25°C must be adjusted to reflect the standard rating at 25°C.
