ZD10-100 Datasheet: A Complete Guide to Specifications, Pinouts, and Applications

Load Regulation

  • 0% to 100% load change: ±0.5% max
  • Line regulation (85–264VAC): ±0.3% max

The ZD10-100 uses a single-transistor forward converter topology, which explains this tight regulation. For applications like LED strip lighting, 0.5% is excellent; for powering a precision op-amp, you may still need a post-regulator.

SOD-323 Package (Surface Mount)

  • Body Length: 2.5 mm ± 0.1 mm
  • Body Width: 1.25 mm ± 0.1 mm
  • Height: 0.95 mm max
  • Pin 1: Cathode (marked with a band or line)
  • Pin 2: Anode

Electrical characteristics (behavioral details)

  • Zener diodes operate in reverse breakdown to maintain a nearly constant voltage across a range of currents. The ZD10‑100 is optimized for regulation around 10 V at low-to-moderate currents.
  • The dynamic (differential) resistance determines regulation quality; lower rz gives tighter voltage under varying load currents.
  • At currents below Izk the diode’s knee may cause poor regulation (Vz falls off). Design circuits to operate above knee current for reliable regulation.
  • Reverse leakage current increases exponentially with temperature; account for this in precision/reference uses.
  • Forward conduction behaves like a standard diode (~0.7 V forward drop at typical forward currents) and must be considered if the diode can be forward‑biased.

3. Thermal and Mechanical Performance

  • Operating Temperature:
    • The datasheet typically rates the operating ambient temperature from -40°C to +85°C.
    • Critical Observation: The derating curves are vital here. At +85°C ambient, the module may only be capable of delivering 50-60% of its rated 10W power. The datasheet graphs this clearly, and designers must heed this limitation to avoid thermal shutdown.
  • Cooling:
    • The module is conduction cooled via the PCB pins and convection. The datasheet usually lacks specific thermal resistance junction-to-ambient ($R_\theta JA$) values, relying instead on "Free Air" conditions. This can be a drawback for rigorous thermal simulation.
