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:

CASE: Void-free, transfer-molded plastic

MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES: 260°C for 10 seconds

FINISH: All external surfaces are corrosion resistant with readily solderable leads

POLARITY: Cathode indicated by molded polarity notch. When operated in zener mode,

cathode will be positive with respect to anode.

MOUNTING POSITION: Any

WEIGHT: Modified L-Bend providing more contact area to bond pad

WAFER FAB LOCATION: Phoenix, Arizona
