Zener Voltage Regulators
500 mW SOD−123 Surface Mount
Three complete series of Zener diodes are offered in the convenient, surface mount plastic SOD−123 package. These devices provide a convenient alternative to the leadless 34−package style.
Features
• 500 mW Rating on FR−4 or FR−5 Board • Wide Zener Reverse Voltage Range − 1.8 V to 43 V • Package Designed for Optimal Automated Board Assembly • Small Package Size for High Density Applications • General Purpose, Medium Current • ESD Rating of Class 3 (>16 kV) per Human Body Model • We declare that the material of product
compliance with RoHS requirements.
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: UL 94 V−0

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. FR−5 = 3.5 X 1.5 inches, using the minimum recommended footprint. 2. Thermal Resistance measurement obtained via infrared Scan Method.
