MMBZ5221B - MMBZ5257B - Zener Diodes November 2015 MMBZ5221B - MMBZ5257B Zener Diodes Tolerance = 5% 2 1 SOT-23 CONNECTION DIAGRAM 2 NC Absolute Maximum Ratings(1, 2) Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the remended operating conditions and stressing the parts to these levels is not remended. In addition, extended exposure to stresses above the remended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted. Symbol Parameter Value Unit RθJA ψJL TSTG TJ Power Dissipation Referencing RθJA, TA = 25°C Referencing ψJL, TL = 25°C Junction-to-Ambient Thermal Resistance(3) Junction-to-Lead Thermal Characteristics (with reference to Cathode) Storage Temperature Range Operating Junction Temperature 250 550 465 -55 to +150 +150 m W °C/W °C/W °C °C Note: 1.These ratings are based on a maximum junction temperature of 150°C. 2.These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations. 3.
