Description

BZX84-C4V7 is a 4.7-volt Zener diode in the SOT-23 package (part of the BZX84 family). It is used for low-power voltage regulation, clamping, or as a reference in shunt configurations.
Key specs (typical):
- Zener voltage: nominal 4.7 V
- Tolerance: C code ≈ ±5%
- Power rating: about 0.5 W (Ptot in SOT-23)
- Test current (Izt): around a few milliamps (vendor varies)
- Package/pinout: SOT-23, cathode usually marked with a band
What “-215” (as in BZX84-C4V7,215) likely means:
- Not an electrical spec; typically a date/lot code or packaging/revision code from a supplier. The electrical characteristics stay those of the C4V7 variant; verify against the specific datasheet.
Applications: simple, compact voltage regulation/clamping for microcontrollers, power rails, protection networks, and reference circuits in low-power designs.

Features

BZX84-C4V7 is a Zener diode (nominal 4.7 V) in an SMT package. Key features:
- Zener voltage: 4.7 V
- Power rating: 0.5 W (at 25°C)
- Package: 2-terminal surface-mount (SOT-23 type for BZX84)
- Operating temp range: -55°C to +125°C
- Tolerance: C class (typical ±5%)
- RoHS compliant / lead-free
- Applications: voltage regulation, references, and overvoltage protection (clamping)
- Small, cost-effective, suitable for general purpose Zener regulation and protection circuits
Note: exact package variant may vary by supplier (SOT-23/SMT form).

Package

Package type: SOT-23 (SC-59) surface-mount. The BZX84-C4V7 uses two terminals (anode/cathode) with the third lead typically not connected.

Pinout

- Pin count: 2 pins (anode and cathode)
- Function: 4.7 V Zener diode (SMD) used for voltage regulation/clamping or overvoltage protection; when reverse-biased it maintains ~4.7 V.

Manufacturer

Manufacturer: Vishay Intertechnology. It is a multinational American-based electronics components company that designs and manufactures discrete semiconductors (like diodes) and passive components (resistors, capacitors, etc.).

Application

Applications of BZX84-C4V7 (4.7 V Zener diode):
- Simple shunt regulator and rough 4.7 V reference in low‑power supplies
- Overvoltage protection and input clamping for logic/microcontroller circuits
- Reference for comparators/ADCs (with proper bypassing and temperature considerations)
- Noise/spike suppression and stabilization in analog signal paths
- Level-shifting/protection in interface circuits
- Basic, inexpensive regulation in battery-powered or compact devices
(Uses are for small-signal, low-current applications.)
