BZT52C5V1SQ

JSMSEMI · Zener Diodes · SOD-323

BZT52C5V1SQ from JSMSEMI, in a SOD-323. 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 K passive Cathode of the zener diode, which is the positive-voltage side in reverse-breakdown regulation; the BZT52C5V1SQ has VZ 4.85 V min, 5.10 V typ, 5.36 V max at IZT = 5 mA.
2 A passive Anode of the zener diode, which is the reference side in reverse-breakdown regulation; the device is rated for 200 mW power dissipation at TA = 25°C.
