CESD24VD5
Changjing · TVS · SOD-523
CESD24VD5 from Changjing, in a SOD-523. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CATHODE | passive | Cathode of the uni-directional ESD protection diode, marked by the bar on the front side; it protects one line with a 24V reverse stand-off voltage, 44V clamping voltage at IPP 7.5A, and 1µA maximum reverse leakage at 24V. |
| 2 | A | passive | Anode of the uni-directional ESD protection diode, the opposite terminal to the cathode; the datasheet does not print a pin number or explicit anode label for this terminal. |
