MMSZ5252C-G3-08 from Vishay Semiconductors is a silicon planar Zener diode with a nominal Zener voltage of 24 V, ±2 % tolerance, 5.2 mA test current (IZT), and 33 Ω dynamic resistance at IZT - designed for precision voltage regulation in low-power analog circuits, power supply feedback loops, and overvoltage protection in automotive body electronics.
For engineers reviewing the MMSZ5252C-G3-08 datasheet, MMSZ5252C-G3-08 pinout, MMSZ5252C-G3-08 application, or MMSZ5252C-G3-08 equivalent, key selection criteria include its SOD-123 package thermal performance (RthJA = 420 K/W on FR-4), 500 mW maximum power dissipation, and temperature coefficient of +0.087 %/°C - critical for stable reference design across -55 °C to +150 °C operating range.
Technical Context
This device operates as a single-element, cathode-anode configured Zener diode optimized for reverse-bias voltage clamping and reference generation. Its 24 V nominal breakdown voltage is specified at thermal equilibrium with 5.2 mA test current, and it exhibits a positive temperature coefficient (+0.087 %/°C), indicating increasing VZ with rising junction temperature.
The MMSZ5252C-G3-08 uses silicon planar construction with UL 94 V-0 molding compound and meets JEDEC J-STD-020 MSL level 1 handling requirements. It delivers 300 mW power dissipation on FR-4 board and supports ESD robustness >8 kV HBM per AEC-Q101.

FAQ
What is the Zener voltage tolerance of MMSZ5252C-G3-08?
The MMSZ5252C-G3-08 has a Zener voltage tolerance of ±2 %, confirmed in the Vishay datasheet (Document Number: 86348, Rev. 1.1). This tighter tolerance versus the ±5 % "B" suffix variants enables higher accuracy in voltage reference and feedback applications without external trimming. The 24 V nominal value is guaranteed between 23.52 V and 24.48 V at 5.2 mA test current and 25 °C ambient.
What is the maximum power dissipation for MMSZ5252C-G3-08 on a standard FR-4 PCB?
The MMSZ5252C-G3-08 delivers 300 mW maximum power dissipation when mounted on an FR-4 board with the recommended soldering footprint per JEDEC 51-3. This is lower than its 500 mW rating under ideal RthJL = 250 K/W conditions, reflecting real-world thermal constraints. Designers must apply derating curves from Figure 1 of the datasheet to ensure safe operation above 25 °C ambient.
Does MMSZ5252C-G3-08 have AEC-Q101 qualification?
The MMSZ5252C-G3-08 is not AEC-Q101 qualified as shipped, but Vishay offers AEC-Q101 qualified versions of the MMSZ52xx-G family upon request - with distinct part numbering and screening. The base MMSZ5252C-G3-08 meets commercial-grade reliability standards and shares the same silicon die and SOD-123 package construction used in qualified variants.
What is the reverse leakage current specification for MMSZ5252C-G3-08?
The MMSZ5252C-G3-08 specifies a maximum reverse leakage current (IR) of 0.1 μA at VR = 18 V, measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and precision current sources where parasitic current paths could degrade accuracy - such as in photodiode amplifier biasing or high-resolution ADC reference dividers.
What is the temperature coefficient of MMSZ5252C-G3-08 and how does it affect regulation?
The MMSZ5252C-G3-08 has a temperature coefficient (αVZ) of +0.087 %/°C, meaning its Zener voltage increases by approximately 20.9 mV per 10 °C rise in junction temperature. This positive drift is typical for 24 V Zeners and must be accounted for in wide-temperature applications; it enables predictable compensation when paired with negative-coefficient components in reference circuits.
