Designed for applications where space is at a premium, the series provides voltage regulation and protection in cellular phones, handheld portables, and high-density PCB assemblies. The device offers 500 mW power dissipation with \u00b15% Zener voltage tolerance. An ESD rating of Class 3 (>16 kV) per Human Body Model provides robust transient protection. The MM5Z series is also available with SZ prefix for automotive applications requiring AEC-Q101 qualification and PPAP capability. The device is Pb-Free, RoHS compliant, and rated MSL 1 for unlimited floor life.","working_principle":"The MM5Z4693T1G operates in the reverse breakdown region of its PN junction. When the reverse voltage across the diode reaches the Zener breakdown voltage (7.5V nominal), the junction enters avalanche breakdown, conducting current while maintaining a nearly constant voltage. The Zener impedance of 15 \u03a9 (maximum at IZT = 5 mA) represents the slope resistance in the breakdown region \u2014 lower impedance means better voltage regulation under varying current conditions. In forward bias, the diode conducts at approximately 0.9V at 10 mA, behaving as a standard silicon diode. Power dissipation is limited to 500 mW at 25\u00b0C, with linear derating of 4.0 mW\/\u00b0C above this temperature. The device's compact SOD-523 package provides thermal resistance of 250\u00b0C\/W (junction-to-ambient on FR-4 board).","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>Cathode<\/td><td>Terminal<\/td><td>Marked by band \u2014 connect to higher voltage for Zener regulation<\/td><\/tr>\n<tr><td>2<\/td><td>Anode<\/td><td>Terminal<\/td><td>Connect to lower voltage or ground for Zener regulation<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>Voltage regulation in cellular phone power management circuits<\/li>\n<li>High-density PCB reference voltage generation in portable instruments<\/li>\n<li>ESD and transient protection for sensitive IC input pins<\/li>\n<li>Overvoltage clamping in handheld portable devices<\/li>\n<li>Automotive telematics and ECU input protection (SZ prefix versions)<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr>\n<tr><td>onsemi<\/td><td>MM5Z7V5T1G<\/td><td>SOD-523<\/td><td>Equivalent 7.5V Zener<\/td><\/tr>\n<tr><td>onsemi<\/td><td>SZMM5Z7V5T1G<\/td><td>SOD-523<\/td><td>AEC-Q101 qualified version<\/td><\/tr>\n<tr><td>Nexperia<\/td><td>PZM5V6NB<\/td><td>SOD-523<\/td><td>Similar 7.5V Zener<\/td><\/tr>\n<tr><td>Vishay<\/td><td>BZT52C7V5-7<\/td><td>SOD-123<\/td><td>Larger package, same voltage<\/td><\/tr>\n<tr><td>onsemi<\/td><td>MMSZ4693T1G<\/td><td>SOD-123<\/td><td>Larger package equivalent<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10494","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/comments?post=10494"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/posts\/10494\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/media?parent=10494"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/categories?post=10494"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/tags?post=10494"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=10494"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
