SS54123H

orisilicon · Leakage Protection ICs · SOP-8

SS54123H from orisilicon, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN1 input Non-inverting input of differential amplifier for zero-sequence current detection, connects to toroidal current transformer secondary.
2 IN2 input Inverting input of differential amplifier for zero-sequence current detection, connects to toroidal current transformer secondary.
3 GND power_in Chip ground and reference potential.
4 OA output Amplifier filter output pin providing amplified and band-pass filtered zero-sequence current signal.
5 DLY input Delay adjustment pin for external RC network configuration of leakage protection trigger delay.
6 OS output SCR trigger output providing 1.5V nominal drive to external thyristor for AC power disconnection upon leakage detection.
7 VS power_in Power supply pin accepting 1.5V regulated internal supply voltage.
8 NC unconnected No connection, floating pin.

CAD (KiCad official)

  • Symbol: SS54123H
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ss54123h-etched.step / ss54123h-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ss54123h.step / ss54123h.glb are the bare package body.
  • Laser-etched variant: ss54123h-etched.step / ss54123h-etched.glb, the same package body with the MPN marked on the die, in a toggleable Adom.LaserEtch group (Fusion-ready).
