Frequently Asked Questions

Which voltage and tolerance define RD18FM-AZ?

The Zener diode provides an 18 V nominal value with 6% tolerance, requiring circuit analysis across the full permitted voltage spread and operating current.

How do power and impedance affect regulation performance?

RD18FM-AZ is rated for 1 W and lists 45 ohm maximum dynamic impedance, so thermal conditions and Zener current influence regulation accuracy.

Can this diode serve voltage-clamping applications?

Yes, the 18 V Zener value can support compatible clamping or reference circuits when the 1 W power ceiling and transient energy remain acceptable.
