개요
Description
A concise intro to BZX84-C8V2-QR:
- Type: Zener diode (BZX84-C family), with a nominal Zener voltage of 8.2 V (Vz specified at the test current).
- Package/marking: SOT-23 two-terminal device; the “QR” suffix indicates packaging (tape-and-reel/RoHS-compliant) for automatic placement.
- Tolerance: the “C” variant typically ≈ ±5% tolerance.
- Power: about 500 mW total dissipation (Ptot at 25°C).
- Use: reverse-biased to regulate/clamp voltage, suitable for regulation references or overvoltage protection in low-power circuits.
- How to connect: cathode to the higher voltage, anode to ground or lower rail.
- Notes: for precise numbers (Izt, Zzt, maximum current, thermal resistance), consult the specific vendor datasheet, as values can vary by manufacturer.
