Zd-95-g-f Schematic -

Look for a wide PCB track going to one pin of the main power inductor or the positive terminal of the LED load. This pin will also connect to the anode of the freewheeling diode. It should not have continuity to GND.

Since you are reading this, you likely have a physical board with a blown ZD-95-G-F. Here is a step-by-step method to reconstruct the schematic yourself:

When you have the schematic (even a hand-drawn one), you can diagnose these typical failures: zd-95-g-f schematic

| Symptom | Likely Cause | Schematic Fix | |---------------------------------|-----------------------------------------------|-----------------------------------| | No output, VCC cycling 9-15V | Short on output; FB pin pulled high/low | Check output diode and LED load | | Output low, dim LED | CS resistor drifted high | Replace R_cs (1% metal film) | | IC cracks open | Overvoltage on DRAIN (spike) | Add snubber (R + C) across inductor| | Intermittent operation | VCC capacitor dried out | Replace 10-47µF electrolytic near IC |

| Pin | Name | Function | |-----|----------|--------------------------------------------| | 1 | FB | Feedback input (connects to output via divider) | | 2 | GND | Ground | | 3 | COMP/NC | Compensation (or not connected) | | 4 | CS | Current sense (across sense resistor to GND)| | 5 | VCC | Supply voltage (usually 12-18V from auxiliary winding) | | 6 | DRAIN | Internal MOSFET drain (to transformer/inductor) | Look for a wide PCB track going to

Note: This is an aggregated pinout from similar SMD-coded parts. Always verify with a multimeter before powering.
