Product details
Overview
MM3Z6V8T1G from onsemi is a 6.8 V, 300 mW Zener voltage regulator diode in SOD−323 package, designed for precision voltage reference and overvoltage protection in space-constrained circuits. It delivers ±5% nominal Zener voltage tolerance at 5 mA test current, 15 Ω dynamic impedance, and 2 µA reverse leakage at 4.0 V, supporting stable regulation in portable power rails.
For engineers reviewing the MM3Z6V8T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its 6.8 V nominal Zener voltage, 300 mW power rating, SOD−323 footprint compatibility, −65°C to +150°C operating range, and AEC−Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to clamp or regulate voltage with predictable threshold behavior. Its low 15 Ω Zener impedance at 5 mA ensures minimal voltage deviation under load transients, while the 2 µA leakage at VR = 4.0 V supports low-power standby integrity.
The device features Class 3 ESD robustness (>16 kV HBM), Pb−free SOD−323 packaging (1.7 mm × 1.25 mm × 0.9 mm), and thermal resistance of 416°C/W - enabling reliable operation in high-density PCBs where thermal dissipation and board area are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.4 V min / 6.8 V nom / 7.2 V max @ IZT = 5 mA - defines precise clamping threshold for 5 V–7 V rail protection |
| Power Dissipation | 300 mW @ TA = 25°C - sets maximum continuous power handling on FR−4 board with 1 cm² pad |
| Zener Impedance (ZZT) | 15 Ω max @ IZT = 5 mA - ensures <±50 mV regulation shift under 1 mA load variation |
| Reverse Leakage (IR) | 2 µA max @ VR = 4.0 V - guarantees negligible quiescent current in battery-backed circuits |
| Temperature Range | −65°C to +150°C - supports operation in automotive engine compartments and industrial ambient extremes |
| ESD Rating | Class 3 (>16 kV) per HBM - enables direct integration into handheld ESD-prone interfaces without added protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V8,115 | Same 6.8 V nominal Zener, but 300 mW rating in SOD-323; higher ZZK (400 Ω vs. 100 Ω) at IZK = 0.5 mA | Less stable at low-current regulation; unsuitable for <1 mA reference designs | Select when cost sensitivity outweighs low-current precision requirements |
| MMSZ4687T1G | 6.8 V Zener in SOD-123; larger 3.5 mm × 1.6 mm footprint and 500 mW rating | Requires PCB layout change; better thermal performance above 100°C ambient | Choose for high-temperature industrial environments where SOD-323 thermal limits are exceeded |

FAQ
What is the nominal Zener voltage and tolerance of MM3Z6V8T1G?
The MM3Z6V8T1G has a nominal Zener voltage of 6.8 V with a tolerance of ±5% (6.4 V to 7.2 V) measured at IZT = 5 mA and TA = 25°C. This tolerance ensures predictable clamping behavior in 5 V–7 V system rails without requiring post-production calibration.
Is MM3Z6V8T1G qualified for automotive applications?
Yes, MM3Z6V8T1G is AEC−Q101 qualified and PPAP capable. It meets stringent automotive reliability standards including temperature cycling, humidity testing, and mechanical shock - making it suitable for use in body control modules, infotainment power supplies, and ADAS sensor interfaces.
What is the maximum reverse leakage current for MM3Z6V8T1G?
The MM3Z6V8T1G exhibits a maximum reverse leakage current of 2 µA at VR = 4.0 V and TA = 25°C. This ultra-low leakage preserves battery life in always-on wearable and IoT devices where standby current must remain below 5 µA.
Can MM3Z6V8T1G be used in place of older MM3Z6V8T1 parts?
Yes, MM3Z6V8T1G is the Pb−free, halogen-free, and RoHS-compliant successor to MM3Z6V8T1. Electrical specifications and SOD−323 mechanical dimensions are identical; only the "G" suffix denotes green packaging - no design or layout changes are required for migration.
What is the thermal resistance and power derating behavior of MM3Z6V8T1G?
MM3Z6V8T1G has a junction-to-ambient thermal resistance (RJA) of 416°C/W on FR−4 board with 1 cm² copper pad. Its power rating derates linearly at 2.4 mW/°C above 25°C ambient, reaching 0 mW at ~150°C - consistent with its −65°C to +150°C storage and operating range.
