Pins are numbered counter-clockwise from the index mark (dot or notch at top).
When viewing the IC from the top, the pin numbering follows the standard counter-clockwise convention starting from the index dot or notch. Electrical Engineering Stack Exchange Pin 4 (VCC/VIN): Typically receives as the main power input. VGH (Voltage Gate High): Often measured around 27V to 30V VGL (Voltage Gate Low): Typically a negative voltage, often around -5V to -7V inx in518 ic pinout diagram top
When searching for a "top view pinout diagram," engineers are typically looking down at the component as it sits on a Printed Circuit Board (PCB). The 1N518 is typically housed in a package. This package is a small glass cylinder with axial leads (wires coming out of both ends). Pins are numbered counter-clockwise from the index mark
