•Zener Voltage Range – 2.4 V to 91 V

•Package Designed for Optimal Automated Board Assembly

•Small Package Size for High Density Applications

•ESD Rating of Class 3 (>16 KV) per Human Body Model

Mechanical Characteristics:

CASE: Void-free, transfer-molded, thermosetting plastic case

FINISH: Corrosion resistant finish, easily solderable

MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES:

260°C for 10 Seconds

POLARITY: Cathode indicated by polarity band

FLAMMABILITY RATING: UL94 V–0
