Frequently Asked Questions

Which voltage and power ratings define RD18S-A?

The Zener diode provides an 18 V nominal value with a 0.2 W rating, so current, junction temperature, and power derating require careful design review.

How does its package support compact PCB applications?

RD18S-A uses a 2-pin Super MiniMold surface-mount form and is rated at 0.2 W, requiring the correct polarity, footprint, and thermal conditions.

Can this diode serve voltage-clamping circuits?

Yes, its 18 V Zener value suits compatible clamping and reference nodes when the 0.2 W ceiling and transient-energy requirements remain acceptable.
