3 Watt Plastic Surface Mount
Silicon Zener Diodes
This complete new line of 3 Watt Zener Diodes offers the following advantages.
Specification Features:
• A Complete Voltage Range — 3.3 to 200 Volts
• Flat Handling Surface for Accurate Placement
• Package Design for Top Side or Bottom Circuit Board Mounting
• Available in Tape and Reel
Mechanical Characteristics:
