4.7V 400mW Zener Diodes (pack of 6)

₹18.00

The 4.7V 400mW Zener diode (DO-35) maintains ~4.7 V in reverse bias, with ±5% tolerance and 250 mA rated current. Used in voltage regulation, low-power power supplies, and switching circuits, it protects components and stabilizes voltage. Operates normally in forward bias like a standard diode.

4.7V 400mW Zener Diodes (pack of 6)

Specifications

Zener Voltage (Vz): 4.7 V (the voltage it maintains in reverse breakdown)
Tolerance: ±5% (so actual voltage could range from ~4.465 V to ~4.935 V)
Power Rating: 400 mW (maximum power it can safely dissipate)
Rated Current: 250 mA (maximum current under ideal conditions)
Temperature Range: up to +175 °C
Package / Case: DO-35 (common small glass diode package)

Key Characteristics

Forward Bias: Acts like a normal diode (conducts after ~0.7 V for silicon).
Reverse Bias: Blocks current until it reaches the breakdown voltage (~4.7 V), then allows current to flow while maintaining ~4.7 V across it.

This property makes it perfect for voltage regulation.

Applications

Voltage Regulation / Reference:
Keeps voltage stable in low-power circuits. Example: a 4.7 V reference for a sensor or microcontroller.
Switching Devices / Protection:
Can be used to limit voltage spikes, protecting sensitive electronics.
Power Supply Circuits:
Often used in low-current regulated power supplies to maintain a constant output voltage.
