MMSZ4689 5.1 V, 0.5 W Zener Diode Features General Description • Compact Surface Mount with Same Footprint as Mini-Melf • 500 mW Rating on FR-4 or FR-5 Board. • Class 3 ESD Rating (>16 kV) per Human Body Model Half watt, general purpose, medium current surface mount zener in the SOD-123 package. The SOD-123 package has the same footprint as the glass mini-melf (LL-34) package and provides a convenient alternative to the leadless package. Top Mark: CU 1: Cathode 2: Anode 2 1 SOD123 Ordering Information Part Number Top Mark Package Packing Method MMSZ4689 CU SOD-123 2L Tape and Reel Absolute Maximum Ratings(1) Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted. Symbol Value Unit Storage Temperature Range -55 to +150 °C Maximum Junction Temperature -55 to +150 °C 970 mV Lead Solder Temperature (Max. 10 second duration) 260 °C Nominal Zener Voltage (VZ) at 50 μA 5.1 V TSTG TJ ΔVZ Parameter Maximum Voltage Change(2) Notes 1. These ratings are limiting values above which the serviceability of any semiconductor device may be impaired. 2. Voltage change is equal to the difference between VZ at 100 μA and VZ at 10 μA. © 2003 Fairchild Semiconductor Corporation MMSZ4689 Rev. 1.1 www.fairchildsemi.com MMSZ4689 — 5.1 V, 0.5 W Zener Diode July 2015 Values are at TA = 25°C unless otherwise noted.
