Zener Voltage Regulators
500 mW SOD−123 Surface Mount
MMSZ52xxxT1G Series, SZMMSZ52xxxT1G Series
SOD−123 CASE 425 STYLE 1
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. Zener voltage in this series are specified with device junction in thermal equilibrium.
Features
• 500 mW Rating on FR−4 or FR−5 Board • Wide Zener Reverse Voltage Range − 2.4 V to 110 V @ Thermal
Equilibrium*
• 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 • SZ Prefix for Automotive and Other Applications Requiring Unique
Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable
• These are Pb−Free Devices
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

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, 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.
