Product details
Overview
MMSZ4690-G3-08 from Vishay Semiconductors is a silicon planar Zener diode with nominal Zener voltage 5.6 V, ±5 % tolerance, 0.05 mA test current, and 500 mW maximum power dissipation at junction-to-lead thermal resistance of 250 K/W. It operates across -55 °C to +150 °C and is used for precision voltage reference and overvoltage protection in low-power analog sensor signal conditioning circuits.
For engineers reviewing the MMSZ4690-G3-08 datasheet, MMSZ4690-G3-08 pinout, MMSZ4690-G3-08 application, or MMSZ4690-G3-08 equivalent, key selection criteria include Zener voltage accuracy at low test current, thermal resistance under FR-4 board mounting, reverse leakage at rated voltage, and SOD-123 package compatibility with automated pick-and-place assembly.
Technical Context
This device functions as a single-element, two-terminal voltage reference diode operating in reverse breakdown mode. Its Zener voltage is specified at thermal equilibrium with IZT = 0.05 mA and exhibits 10 μA maximum reverse current at VR = 4 V.
The SOD-123 surface-mount package supports JEDEC-compliant reflow soldering up to 260 °C peak temperature, with MSL level 1 moisture sensitivity and UL 94 V-0 molding compound. Junction-to-ambient thermal resistance is 420 K/W on FR-4 board with recommended footprint.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C5V6 | Same 5.6 V nominal Zener, but ±1 % tolerance and 250 mW Ptot rating | Higher precision required in metrology-grade references; lower power limit restricts use in higher-current bias networks | Select BZX584C5V6 when tighter voltage tolerance outweighs need for 500 mW dissipation capability |
| MMBZ5232BS | 5.6 V nominal, ±5 % tolerance, SOT-23 package, 350 mW Ptot, 100 nA IR at 4 V | Smaller footprint enables dense PCB layouts; lower leakage benefits ultra-low-power sleep modes | Select MMBZ5232BS when board space is constrained and sub-μA leakage is critical, accepting reduced thermal margin |
Compared with MMSZ4690-G3-08, BZX584C5V6 offers tighter voltage control but sacrifices 40 % power handling, while MMBZ5232BS trades thermal robustness for miniaturization and ultra-low leakage-making each suitable for distinct design priorities in reference stability, power margin, or layout density.

FAQ
What is the Zener voltage tolerance specification for MMSZ4690-G3-08?
The MMSZ4690-G3-08 has a Zener voltage tolerance of ±5 %, meaning its actual breakdown voltage falls between 5.32 V and 5.88 V when measured at the specified test current of 0.05 mA under thermal equilibrium conditions. This tolerance is confirmed in the Electrical Characteristics table of Vishay's official datasheet document number 86347, revision 1.1.
Is MMSZ4690-G3-08 qualified for automotive applications?
MMSZ4690-G3-08 is not automatically AEC-Q101 qualified; however, AEC-Q101 qualified versions are available upon request with appropriate part numbering. The base MMSZ4690-G3-08 meets ESD requirements per AEC-Q101 (HBM > 8 kV, MM > 800 V), and its -55 °C to +150 °C operating temperature range supports under-hood and cabin automotive use when paired with proper thermal design.
What is the maximum reverse leakage current for MMSZ4690-G3-08 at 4 V?
The maximum reverse leakage current for MMSZ4690-G3-08 is 4 μA when tested at VR = 4 V and Tamb = 25 °C. This value is explicitly listed in the Electrical Characteristics table for the MMSZ4690-G part variant and applies identically to the MMSZ4690-G3-08 ordering code, which shares identical electrical specifications and SOD-123 packaging.
Can MMSZ4690-G3-08 be used in place of MMSZ4689-G or MMSZ4691-G?
No-MMSZ4690-G3-08 is not interchangeable with MMSZ4689-G (5.1 V nominal) or MMSZ4691-G (6.2 V nominal), as each part has a distinct Zener voltage range. Substituting them would shift the regulation point by ≥0.5 V, potentially causing incorrect biasing or reference errors. Always verify voltage requirements before selecting among the MMSZ4681-G to MMSZ4717-G family.
What is the thermal resistance junction-to-ambient for MMSZ4690-G3-08 on FR-4 board?
The thermal resistance junction-to-ambient (RthJA) for MMSZ4690-G3-08 is 420 K/W when mounted on an FR-4 printed circuit board using Vishay's recommended soldering footprint per JEDEC® 51-3. This value determines allowable power dissipation at elevated ambient temperatures and is critical for thermal derating calculations in enclosed or high-temperature environments.
