BZX384-C11

BZX384-C11 is a small-signal Zener diode in the BZX384 family. Key points:
- Function: reverse-biased diode that clamps/regulates voltage in low-power circuits; used as a voltage reference or overvoltage protector.
- Voltage: nominal Zener voltage ≈ 11 V.
- Power: typically rated around 0.5 W (Pmax), with ambient-temperature derating.
- Package: compact SMD (commonly in the SOD-123 family, depending on vendor).
- Tolerance: the “C” suffix usually indicates a tolerance around ±5%.
- Operating current: typically specified at a modest test current (often ~5 mA) for the Zener knee and impedance.
- Typical specs to check in datasheets: VZ accuracy, dynamic impedance (Zz), IZ, and maximum reverse current.
Use when you need an 11 V reference/clamp in a compact, inexpensive Zener-based regulator or protection circuit. For exact parameters, consult the manufacturer’s datasheet.
