Description
BZX84B4V7LT1G is a Zener diode from the BZX84 family. It provides a fixed Zener voltage of about 4.7 V for clamping or regulation in small-signal, surface-mount designs.
Key points:
- Zener voltage: ≈ 4.7 V
- Tolerance: typically ±5% (the “B” variant)
- Power rating: around 0.5 W (at 25°C)
- Package: tiny SMD, RoHS-compliant; LT1G denotes the specific tape/lot/package variant
- Uses: voltage regulation, reference/clamping, surge protection
- Connection: cathode to the higher voltage, anode to ground
In circuits, it’s often used to clamp supply rails near 4.7 V or to provide a simple reference for small regulator circuits.
