SZBZX84B4V7LT1G

SZBZX84B4V7LT1G is a small-signal surface-mount Zener diode. Key points:
- Function: 4.7 V Zener voltage device used to clamp or regulate voltage, or as a simple reference in low-power circuits.
- Family: BZX84B4V7 (tolerance around ±5% typical for the B variant).
- Package/finish: Lead-free, RoHS-compliant variant; “SZ”/“LT1G” suffixes denote factory code, packaging, and lot/date codes for this specific manufacturer.
- Electrical notes: Rated for about 0.5 W dissipation; specified at a test current (IZT) to define VZ. Exact values (IZT, ZZT, leakage, max current) vary by vendor, so refer to the datasheet for the precise part.
- Applications: Over-voltage protection, voltage clamping, and simple voltage references in low-power electronics.
If you need exact parameters (IZT, dynamic resistance, maximum current, packaging), check the datasheet for SZBZX84B4V7LT1G or cross-reference with BZX84B4V7 from major manufacturers.

Manufacturer: Diodes Incorporated (Diodes Inc.).
Type of company: a global semiconductor manufacturer that designs and supplies discrete semiconductors and analog/mixed‑signal ICs — principally diodes, transistors, MOSFETs, power‑management and interface devices for consumer, computing, industrial and automotive markets.

SZBZX84B4V7LT1G is a 4.7 V Zener diode (0.5 W). Common applications:
- Shunt regulator and voltage reference in low‑current circuits (microcontrollers, sensors)
- Rail and I/O line clamping / overvoltage protection
- Simple Zener-based regulator in small, battery-powered supplies
- Protective clamp for analog signals against voltage transients
Note: It provides about 4.7 V in reverse breakdown and is not a precision reference. Use with a suitable series resistor.

The SZBZX84B4V7LT1G is supplied in a SOD523 (SOD-523) miniature surface-mount package.
