68V 5W Zener Diode – Reliable Voltage Regulation

68V 5W Zener Diode for Precision Voltage Control

This high-quality 68V 5W Zener diode (originally NTE5151A) is engineered for reliable voltage regulation and circuit protection in demanding electronic designs. Featuring a nominal regulating voltage of 68.0 volts and a robust 5 watt power dissipation capability, it is ideal for stabilizing and limiting voltages in power supplies, reference circuits, or protection networks.

Technical Data

• Nominal Zener Voltage: 68.0V
• Power Dissipation: 5W
• Mounting Style: Through hole
• Package: Sold individually (Qty: 1 per package)

Applications

• Voltage regulation and reference in power supplies
• Overvoltage protection circuits
• Clamping circuits
• Surge and transient suppression

Usage Instructions

For stable performance, ensure proper heat sinking if operating near maximum power ratings. Connect the cathode to the higher potential in the circuit for Zener regulation. Suitable for both linear and switching topologies requiring a steady 68V reference or regulation point.
