RN1301

TOSHIBA · Digital Transistors · SOT-323

RN1301 from TOSHIBA, in a SOT-323. 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 BASE input Base input through built-in R1 (4.7 kΩ for RN1301) with R2 to emitter; VEBO max 10 V (RN1301 to 1304).
2 EMITTER passive Emitter of the NPN transistor, connected to the R2 bias resistor; VEBO max 10 V (RN1301 to 1304).
3 COLLECTOR passive Collector of the NPN transistor; VCEO max 50 V, VCBO max 50 V, IC max 100 mA.

CAD (KiCad official)

  • Symbol: RN1301
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: rn1301-etched.step / rn1301-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rn1301.step / rn1301.glb are the bare package body.
