The 1N4738AM is a Zener diode manufactured by Leshan Radio. Zener diodes are semiconductor devices that allow current to flow in either forward or reverse direction, but when the voltage reaches the Zener voltage, it starts conducting in the reverse direction and keeps the voltage relatively constant.

Applications:

• Voltage regulation
• Voltage clamping
• Overvoltage protection
• Reference voltage in power supplies
• Transient voltage suppression

Features:

• Zener Voltage: 8.2V
• High reliability
• Low leakage current
• DO-41 package

Benefits:

• Provides a stable voltage reference
• Protects circuits from voltage spikes
• Simple and cost-effective voltage regulation

Technical Specifications:

Key specifications for the 1N4738AM include:

• Zener Voltage (VZ): 8.2V ±5%
• Power Dissipation (PD): 1W
• Operating Temperature Range: -65°C to +200°C
• Forward Voltage (VF): 1.2V at 200mA
• Package: DO-41

This Zener diode is commonly used in various electronic circuits for voltage regulation and protection purposes due to its reliable performance and readily available DO-41 package.
