Zener Voltage Regulators
225 mW SOT−23 Surface Mount
MMBZ52xxBLT1G Series, SZMMBZ52xxBLT1G Series
This series of Zener diodes is offered in the convenient, surface mount plastic SOT−23 package. These devices are designed to provide voltage regulation with minimum space requirement. They are well suited for applications such as cellular phones, hand held portables, and high density PC boards.
Features
• 225 mW Rating on FR−4 or FR−5 Board • 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 • SZ Prefix for Automotive and Other Applications Requiring Unique
Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
