MMBD4148CA

Guangdong Hottech · Switching Diodes · SOT-23

MMBD4148CA from Guangdong Hottech, in a SOT-23. 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 K1 passive Cathode of diode 1; reverse blocking up to VR = 100 V (VRRM), reverse leakage IR1 ≤ 5 µA at VR = 75 V.
2 K2 passive Cathode of diode 2; reverse blocking up to VR = 100 V (VRRM), reverse leakage IR1 ≤ 5 µA at VR = 75 V.
3 A passive Common anode shared by both diodes; forward voltage VF ≤ 1 V at IF = 10 mA, continuous forward current IFM = 300 mA.

CAD (KiCad official)

  • Symbol: MMBD4148CA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbd4148ca-etched.step / mmbd4148ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbd4148ca.step / mmbd4148ca.glb are the bare package body.

Provenance

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

  • Datasheet: Guangdong Hottech datasheet (2 pp, sha256 c0e63fb6ecad422a, retrieved 2026-09-29, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
