For engineers reviewing the MMSZ5264B-E3-08 datasheet, MMSZ5264B-E3-08 pinout, MMSZ5264B-E3-08 application, or MMSZ5264B-E3-08 equivalent, key selection criteria include its 60 V zener voltage, 170 Ω dynamic resistance at IZT, -65 °C to +150 °C operating temperature range, SOD-123 package, and AEC-Q101 qualification availability in HE3_A variants.
Technical Context
This device operates as a single-element, cathode-anode configured Zener diode optimized for stable reverse-bias breakdown under thermal equilibrium conditions. Its 60 V nominal zener voltage is specified at 2.1 mA test current with 170 Ω dynamic resistance and a positive temperature coefficient of +0.097 %/°C.
The SOD-123 surface-mount package delivers 300 mW power dissipation on FR-4 board and 500 mW with RthJL = 250 K/W, supporting compact PCB layouts while maintaining junction temperatures up to 150 °C under defined thermal conditions.

FAQ
What is the nominal zener voltage and tolerance of the MMSZ5264B-E3-08?
The MMSZ5264B-E3-08 has a nominal zener voltage of 60 V with a tolerance of ±5 %, as indicated by the "B" suffix in the part number. This specification is measured at a test current of 2.1 mA under thermal equilibrium conditions and applies directly to the MMSZ5264B-E3-08 device in its standard SOD-123 package.
Is the MMSZ5264B-E3-08 suitable for automotive applications?
The MMSZ5264B-E3-08 itself is a commercial-grade part, but Vishay offers an AEC-Q101 qualified version - MMSZ5264B-HE3_A-08 - with identical electrical specifications and enhanced reliability testing. For automotive use, specify the HE3_A variant; the MMSZ5264B-E3-08 is intended for industrial and general-purpose applications.
What is the maximum power dissipation of the MMSZ5264B-E3-08 on a standard FR-4 PCB?
The MMSZ5264B-E3-08 is rated for 300 mW maximum power dissipation when mounted on an FR-4 printed circuit board using the recommended soldering footprint per JEDEC 51-3. This value assumes proper thermal layout and accounts for the device's 420 K/W junction-to-ambient thermal resistance under those conditions.
Does the MMSZ5264B-E3-08 have a specified temperature coefficient?
Yes, the MMSZ5264B-E3-08 has a temperature coefficient of +0.097 %/°C, meaning its zener voltage increases by approximately 0.097 % per degree Celsius rise in junction temperature. This parameter is confirmed in the Electrical Characteristics table of the Vishay datasheet document 86344 and applies specifically to the MMSZ5264B-E3-08 at its 2.1 mA test current.
What package type does the MMSZ5264B-E3-08 use, and what are its key mechanical dimensions?
The MMSZ5264B-E3-08 uses the SOD-123 surface-mount package with overall dimensions of 2.7 mm × 3.7 mm × 0.12 mm (length × width × thickness), cathode bar marking, and 1.55 mm lead-to-lead distance. These dimensions are standardized per Vishay's package drawing S8-V-3910.01-003 and apply exclusively to the MMSZ5264B-E3-08 ordering code.
