A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" when a certain set reverse voltage, known as the Zener voltage, is reached.

Technical Specification:

• Zener Voltage: 33V
• Zener Voltage Tolerance: ±5%
• Maximum Reverse Leakage Current: 10µA
• Operating Temperature:-65 °C to + 150°C
• Power: 1/2 W

Features:

• Power dissipation capacity is very high
• High accuracy
• Small size
• Low cost

 Applications:

• Over-voltage protection
• Voltage regulation
• Voltage reference
• Surge suppression
• Switching applications
• Clipper circuits
