TB310S

Shandong Jingdao Microelectronics · Bridge Rectifiers · ABS

TB310S from Shandong Jingdao Microelectronics, in a ABS. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 AC1 passive Input pin (~) of the bridge for the AC input; TB310S is rated 100 V VRRM, 70 V VRMS.
2 AC2 passive Input pin (~) of the bridge for the AC input; TB310S is rated 100 V VRRM, 70 V VRMS.
3 DC+ passive Output anode (+) of the rectified DC output, rated 3.0 A average rectified output current at Tc = 100 °C.
4 DC- passive Output cathode (-) of the rectified DC output, rated 3.0 A average rectified output current at Tc = 100 °C.

CAD (KiCad official)

  • Symbol: TB310S
  • Footprint: Diode_SMD:Diode_Bridge_Diotec_ABS
  • 3D model: ABS (KiCad packages3D, STEP)
  • 3D model files: tb310s-etched.step / tb310s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tb310s.step / tb310s.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
