Littelfuse P-1DF-1E Fixed Voltage Single Port Thyristors are SIDACtor® devices designed to protect sensitive SLICs (Subscriber Line Interface Circuits) from damaging overvoltage transients. The components provide single-port protection using a fixed voltage switching device for negative surges. Positive surges are routed through internal diodes to a ground reference. The MS-012 packaged thyristors are pin-to-pin compatible with the industry standard programmable SO-8 SLIC protectors. Surge capability does not degrade after multiple surge events within limit. The MS-013 package thyristors feature low voltage overshoot, low on-state voltage, and fails short circuit when surged in excess of ratings. Littelfuse P-1DF-1E Thyristors are RoHS compliant and lead-free.
