AZ34063UMTR-G1

Diodes Incorporated · DC-DC Converters · SOIC-8

AZ34063UMTR-G1 from Diodes Incorporated, in a SOIC-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 Switch Collector output Internal switch transistor collector. Rated to 40V and 1.5A switch current; connect to inductor/load per topology.
2 Switch Emitter output Internal switch transistor emitter. Rated 40V (VPIN1=40V) and 1.5A; connect to load/return path per topology.
3 Timing Capacitor passive External timing capacitor (CT) sets the oscillator switching frequency (up to 180 kHz). Typical value ~470 pF for the application circuits shown.
4 GND power_in Ground pin for all internal circuits.
5 Comparator Inverting Input input Inverting input of the internal comparator; compared against the 1.25V internal reference. Connect to the feedback resistor divider from VOUT to set output voltage. Input range -0.3V to 40V.
6 VCC power_in Voltage supply pin. Recommended operating range 3V to 36V (absolute maximum 40V).
7 IPK Sense input Peak current sense input. Monitors the voltage drop across an external current-sense resistor (Rsc) to limit peak current through the internal switch.
8 Driver Collector output Voltage driver collector. Rated 40V and up to 100 mA driver current; typically tied to VCC through a resistor in step-up applications.

CAD (KiCad official)

  • Symbol: AZ34063UMTR-G1
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: az34063umtr-g1-etched.step / az34063umtr-g1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az34063umtr-g1.step / az34063umtr-g1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
az34063umtr-g1.step 122 KB You want the bare part, or you mark your own boards.
az34063umtr-g1-etched.step 2.7 MB You want the part with AZ34063UMTR-G1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 671 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
