SEMICONDUCTOR PROTECTION FUSES
A30QS Amp-Trap
®
Semiconductor Protection fuses are
intended for the protection of Power Semiconductors
such as Diodes, Phase Control SCR’s and other Power
Semiconductor devices. The A30QS is recommended for
new applications providing solutions for your critical
protection needs at 300V and less semiconductors.
Features / Benefits
