概述

Description

BZX84-C8V2-QR is an 8.2-volt Zener diode in the SOT-23 package (BZX84-C series). It serves as a small, low-power voltage regulator/reference or a voltage clamp in compact circuits. Typical dissipation is about 0.5 W at 25°C. The “-QR” suffix denotes RoHS-compliant packaging (lead-free) and usually reel/tape packaging for automated assembly. In operation, it is reverse-biased to clamp voltages near 8.2 V, with a defined dynamic impedance (per datasheet). Pinout uses two active leads (anode and cathode) in the SOT-23 package; refer to the datasheet for exact pin assignments.

Features

BZX84-C8V2-QR is a Zener diode (BZX84 family) in SOT-23.
Key features:
- Zener voltage: 8.2 V (nominal)
- Tolerance: ±5% (C grade)
- Power rating: 0.5 W
- Package: SOT-23
- Packaging: Tape & Reel (QR)
- Temperature range: -55°C to +150°C
- RoHS compliant
- Applications: voltage regulation/reference, overvoltage protection, clamping
Note: Pinout is the standard two-terminal Zener in SOT-23 (one lead pair used).

Package

BZX84-C8V2-QR uses a SOT-23 (SOT-23-3) surface-mount package.

Pinout

- Pin count: 3 pins (SOT-23 package). Two active terminals (anode and cathode) and typically a No-Connect pin.
- Function: Zener diode with a nominal zener voltage of 8.2 V, used for voltage regulation and clamping/protection.

Manufacturer

Manufacturer: Vishay Intertechnology, Inc.
What kind of company: Vishay is a multinational semiconductor company that designs and manufactures discrete semiconductors (e.g., diodes, transistors) and passive components (resistors, capacitors, inductors) for electronics.

Application

BZX84-C8V2-QR is an 8.2 V zener diode (SOT-23). Applications:
- Shunt regulator for low‑current supplies
- Fixed reference for comparators/regulators
- Overvoltage and transient protection for rails and inputs
- Clamp/clip protection on signal lines
- Protection/snubber in battery-powered or portable devices
(0.5 W rating typical; use where ~8.2 V clamping or reference is suitable.)
