P-1DF-1 SLIC SIDACtor Protection Thyristors

Littelfuse P-1DF-1 Fixed Voltage Enhanced Single Port Thyristors are SIDACtor® components 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 enhanced switching diodes to a ground reference. The MS-012 packaged thyristors are pin-to-pin compatible with industry standard programmable SO-8 SLIC protectors. Surge capability does not degrade after multiple surge events within limit. Littelfuse P-1DF-1 thyristors feature low voltage overshoot, low on-state voltage, and fails short circuit when surged in excess of ratings.
