|---|---|---|---|
| SD55127 | SD55127 is a high-performance CMOS circuit dedicated to ground-fault protection. It integrates a regulated power supply, amplifier, comparator, delay, counter, trip control, and trip driver. External components include a trip coil, varistor, zener diode, diode, resistor, and capacitor. | SOP14 | |
| SD55125 | Type A Circuit for Leakage Current Protection (CMOS). | SOP8 | |
| SD55126 | SD55126 is a high-performance CMOS circuit dedicated to ground-fault protection. It integrates a regulated power supply, amplifier, comparator, delay, counter, trip control, and trip driver. External components include a trip coil, varistor, zener diode, diode, resistor, and capacitor. | SOP8 | |
| SD55125ADA | SD55125ADA is a high-performance CMOS circuit dedicated to ground-fault protection. It integrates a regulated power supply, amplifier, comparator, delay, counter, trip control, and trip driver. External components include a trip coil, varistor, zener diode, diode, resistor, and capacitor. | SOP8 | |
| SD54123B | SD54123B is a high-performance CMOS circuit dedicated to ground-fault protection. It integrates a regulated power supply, amplifier, comparator, delay, counter, trip control, and trip driver. External components include a trip coil, varistor, zener diode, diode, resistor, and capacitor. | SOP8 | |
| SD54123 | SD54123 is a high-speed ground-fault protection circuit with a differential amplifier, latch, and regulator. Connected to a zero-current transformer (ZCT), it detects differential current; the amplifier and an external capacitor feed the latch, whose output suits high-speed ground-fault interrupters. | SOP8，SIP8 | |
| SD4147 | SD4147 is a low-power ground-fault interrupter (GFI) controller. It detects hazardous current paths to ground and ground-to-neutral faults, and its application circuit disconnects the load before electric shock causes injury. | SOT-23-6L | |
| SD4145 | SD4145 is a low-power controller for ground-fault interrupters in AC power outlets. | DIP8,SOP8 | |
| SD4140 | SD4140 is a low-power controller for ground-fault circuit interrupters in AC outlet appliances. It detects hazardous current paths to ground, such as when equipment falls into water, and disconnects the line before harmful or fatal electric shock occurs. | DIP8,SOP8 |
