Product details
Overview
MM3Z5V6T1 from onsemi is a 5.6 V, 200 mW surface-mount Zener diode in SOD−323 package, with 40 Ω dynamic impedance at 5 mA test current, <1 µA leakage at 2 V reverse bias, and ±2.0 mV/°C temperature coefficient-used for precision voltage reference and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the MM3Z5V6T1 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal derating behavior, cathode/anode terminal mapping, Pb-free compliance status, and direct alternatives for low-power regulation design.
Technical Context
The MM3Z5V6T1 operates as a two-terminal voltage reference device, regulating reverse-biased voltage across its cathode–anode junction at nominal 5.6 V with tight tolerance (5.2–6.0 V) and low dynamic impedance (40 Ω @ 5 mA). It exhibits a negative temperature coefficient of −2.0 mV/°C, enabling predictable drift compensation in stable reference circuits.
Designed for FR-4 PCB mounting with 260°C soldering tolerance, it delivers 200 mW steady-state dissipation at 25°C ambient, derating linearly at 1.5 mW/°C above that temperature, and features Class 3 ESD robustness (>16 kV HBM) and UL 94 V−0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2–6.0 V at IZT = 5 mA - defines regulation band for low-noise reference use |
| Zener Impedance (ZZT) | 40 Ω max @ 5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (PD) | 200 mW @ TA = 25°C - sets maximum continuous power handling on standard FR-4 board |
| Leakage Current (IR) | <1 µA @ VR = 2 V - guarantees negligible standby current in battery-powered systems |
| Temp. Coefficient (αVZ) | −2.0 mV/°C - enables predictable voltage drift correction in temperature-stable designs |
| Capacitance (C) | 200 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering capability |
| ESD Rating | Class 3 (>16 kV) per HBM - supports robust handling in manual assembly and field environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V6 | Same 5.6 V nominal, but 300 mW rating and SOD-323 package; higher leakage (≤3 µA @ 2 V) | Better suited for higher-power regulation; less ideal for ultra-low-leakage battery monitoring | Select when >200 mW headroom is required and leakage tolerance >1 µA is acceptable |

FAQ
What is the Zener voltage tolerance of MM3Z5V6T1 at 5 mA test current?
The MM3Z5V6T1 has a guaranteed Zener voltage range of 5.2 V to 6.0 V when tested at IZT = 5 mA and TA = 25°C. This ±0.4 V tolerance (±7.1% of nominal 5.6 V) ensures reliable regulation in precision reference applications without requiring post-manufacturing trimming.
Does MM3Z5V6T1 support lead-free soldering processes?
Yes, the MM3Z5V6T1 is offered in a Pb−Free package (indicated by the "G" suffix), qualified for reflow soldering at peak temperatures up to 260°C for 10 seconds. Its terminations are plated with pure tin, meeting JEDEC J-STD-020 and RoHS requirements.
What is the maximum junction temperature for MM3Z5V6T1?
The MM3Z5V6T1 has a specified junction and storage temperature range of −65°C to +150°C. Its thermal resistance RJA is 635°C/W on FR-4 board, meaning junction temperature rises ~635°C per watt dissipated-so at full 200 mW, ΔT ≈ 127°C above ambient, staying within limit at TA ≤ 23°C.
How does the temperature coefficient affect MM3Z5V6T1's voltage stability?
The MM3Z5V6T1 has a temperature coefficient of −2.0 mV/°C, meaning its Zener voltage decreases by 2 mV per degree Celsius rise in junction temperature. This predictable drift allows designers to compensate in firmware or analog circuitry for applications requiring stable references across −40°C to +85°C.
Can MM3Z5V6T1 be used as a forward-biased diode?
Yes-the MM3Z5V6T1 exhibits a forward voltage VF ≤ 0.9 V at IF = 10 mA, making it usable as a low-drop rectifier or clamping diode in low-current signal paths. However, its primary design intent and characterized specifications are for reverse-biased Zener operation at 5.6 V.
