Product details
Overview
MM5Z4694T5G from onsemi is a 500 mW, 8.2 V nominal Zener voltage regulator diode in SOD−523 package, with 50 µA test current (IZT), 1 µA reverse leakage at 6.2 V (IR), and ±5% voltage tolerance. It provides precision voltage reference and overvoltage clamping in space-constrained portable electronics.
For engineers reviewing the MM5Z4694T5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage accuracy at IZT = 50 µA, low-leakage operation below 6.2 V, thermal derating above 75°C, and ESD robustness (>16 kV HBM).
Technical Context
This device operates as a two-terminal silicon Zener diode optimized for low-current voltage regulation and transient suppression. Its 8.2 V nominal Zener voltage is specified at IZT = 50 µA with ±5% tolerance, and it exhibits 1 µA reverse leakage at VR = 6.2 V - indicating tight regulation near knee voltage.
The SOD−523 package enables high-density PCB placement while maintaining 500 mW power dissipation on FR−5 board at TL = 75°C, with thermal resistance RJA = 250 °C/W and junction temperature range −55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Power Dissipation (PD) | 500 mW on FR−5 board @ TL = 75°C; supports continuous regulation in compact layouts |
| Reverse Leakage (IR) | 1 µA @ VR = 6.2 V; enables low-quiescent monitoring of supply rails without loading |
| ESD Rating | Class 3 (>16 kV) per HBM; protects against handling-induced damage in automated assembly |
| Junction Temp Range | −55°C to +150°C; suitable for automotive cabin and industrial ambient environments |

Pinout & Package
SOD−523 surface-mount package with molded thermosetting plastic case, UL 94 V−0 flammability rating, and corrosion-resistant solderable finish. Cathode identified by polarity band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated output node; sinks current during Zener conduction |
| 2 (Non-banded End) | Anode | Connected to ground or lower-potential rail; completes bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low IZT operation | Regulates stably at only 50 µA test current - ideal for battery-powered sensor nodes |
| High ESD immunity | 16 kV HBM rating eliminates need for external ESD protection in handheld interfaces |
| Pb-free & RoHS compliant | Meets global environmental compliance without derating or requalification |
| Thermal stability | Derates linearly at 4.0 mW/°C above 75°C - predictable power margin in hot enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C8V2 | Same 8.2 V nominal, but SOD-323 package (1.7 × 1.3 mm); 200 mW rating; 100 nA IR @ 6.2 V | Lower leakage enables higher-impedance divider networks; smaller power margin limits surge handling | Select when ultra-low leakage dominates over surge robustness and board space allows larger footprint |
| MMSZ4694T1G | SOD-123 package (3.7 × 1.6 mm); 500 mW rating; same 7.79–8.61 V range; 1 µA IR @ 6.2 V | Larger size eases hand-soldering and improves thermal mass; incompatible with 0402 land pattern | Select when manual rework or higher thermal inertia is required, and SOD-523 density is not mandatory |
Compared with BZX584-C8V2 and MMSZ4694T1G, MM5Z4694T5G uniquely balances ultra-small footprint (SOD−523), full 500 mW dissipation, and 1 µA leakage - making it optimal for miniaturized, battery-sensitive, and thermally constrained designs.

FAQ
What is the Zener voltage tolerance of MM5Z4694T5G?
The MM5Z4694T5G has a nominal Zener voltage of 8.2 V with a tolerance of ±5%, resulting in a guaranteed range of 7.79 V to 8.61 V when tested at IZT = 50 µA and TA = 25°C. This tolerance remains valid across the full operating temperature range of −55°C to +150°C, as confirmed in the Electrical Characteristics table on page 3 of the onsemi datasheet.
Does MM5Z4694T5G meet automotive qualification standards?
The MM5Z4694T5G is not AEC−Q101 qualified; only the SZMM5Z4694T5G variant carries that qualification. The MM5Z4694T5G is rated for industrial and consumer applications with junction temperature range −55°C to +150°C and ESD robustness >16 kV HBM, but lacks PPAP documentation and automotive-specific process controls.
What is the maximum reverse leakage current for MM5Z4694T5G?
The MM5Z4694T5G specifies a maximum reverse leakage current (IR) of 1 µA at VR = 6.2 V and TA = 25°C. This value is measured under standardized conditions and reflects the device's ability to maintain low standby current in voltage-monitoring circuits without compromising accuracy.
Can MM5Z4694T5G be used in place of MM5Z4694T1G?
Yes - MM5Z4694T5G and MM5Z4694T1G share identical electrical specifications, thermal ratings, and SOD−523 packaging. The only difference is packaging quantity: T5G ships in 8,000-unit tape-and-reel versus T1G's 3,000-unit reel. Both are Pb-free, RoHS-compliant, and functionally interchangeable in all designs.
What is the thermal resistance of MM5Z4694T5G?
The MM5Z4694T5G has a junction-to-ambient thermal resistance (RJA) of 250 °C/W, measured via infrared scan method on FR−5 board. This value governs steady-state temperature rise and supports derating to 4.0 mW/°C above TL = 75°C - critical for thermal design in sealed enclosures.
