概述

Description

BZX84C6V2 is a Zener diode (BZX84 series) with a nominal Zener voltage of 6.2 V, in a tiny SOT-23 package. It is a low‑power (≈0.5 W) device used for voltage regulation and overvoltage/clamping in small circuits. The “C” tolerance class means ±5% at the test current (Iz ≈ 5 mA). Typical dynamic impedance is around a few tens of ohms (≈60 Ω) at Iz. How to use: reverse‑bias it across the node to be regulated, with a suitable series resistor from the supply; it will clamp the node near 6.2 V. Common applications include simple shunt regulators, voltage references, and input protection on low‑power rails.

Features

Concise features of BZX84C6V2:
- Small-signal Zener diode for voltage regulation and protection
- Nominal Zener voltage: 6.2 V
- Power rating: about 0.5 W (1/2 W)
- Package: surface-mount (commonly SOT-23)
- Reverse breakdown at approximately 6.2 V; usable at a test current around 5 mA
- Low reverse leakage below breakdown; good stability in regulation
- Wide operating temperature range (typically -55°C to +125°C)
- RoHS compliant; available in standard tape/ reel packaging
- Used for reference voltages, clamping, and simple overvoltage protection in low-power circuits
Note: Exact tolerances and parameters depend on the variant and manufacturer.

Package

BZX84C6V2 is a surface-mount Zener diode in an SMD SOD-123 package (0.5 W).

Pinout

- Pin count: 2 terminals (anode and cathode); in SOT-23 packages the middle pad is usually unused (NC).
- Function: Zener diode with a nominal Zener voltage of 6.2 V, used for voltage regulation, reference, or overvoltage/clamp protection.

Manufacturer
