Semiconductor Protection Fuses
A15QS Amp-trap
®
Form 101 Semiconductor Protection
fuses were designed for
the specific protection of diodes and other
semiconductor devices rated 150VAC/DC.
The A15QS product line’s compact design is perfect for
those applications that have limitations on available
space.
Features/Benefits
• Low l
