Pinout
The WS4.5D3HV is a 4.5V Zener diode in a SOD-323 (SC-76) surface-mount package.
- Pin Count: 2 pins (anode and cathode).
- Function: Acts as a voltage regulator or protection device, maintaining a stable 4.5V reverse breakdown voltage by shunting excess current when the voltage exceeds its threshold.
Key features:
- Low leakage current
- High reliability
- Compact size (ideal for space-constrained PCBs)
Common applications include voltage clamping, ESD protection, and power supply stabilization.

Package
The WS4.5D3HV is a surface-mount device (SMD) package, typically a DFN (Dual Flat No-leads) or QFN (Quad Flat No-leads) type, designed for high-voltage applications. It features a compact, leadless design with exposed thermal pads for efficient heat dissipation. Exact dimensions vary, but it’s commonly around 4.5mm x 3mm. Check the datasheet for precise specs.
