Product details
Overview
MM3Z3V6T1 from onsemi is a 3.6 V nominal Zener diode in SOD−323 package, rated for 200 mW steady-state power dissipation, with 90 Ω maximum Zener impedance at 5 mA test current and 5 µA reverse leakage at 1.0 V. It provides precision voltage regulation in space-constrained portable electronics such as cellular phones and high-density PCBs.
For engineers reviewing the MM3Z3V6T1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.4–3.8 V Zener voltage tolerance, −3.5 mV/°C temperature coefficient, Pb-free SOD−323 footprint, and Class 3 ESD rating (>16 kV HBM).
Technical Context
The MM3Z3V6T1 operates as a two-terminal voltage reference device, conducting in reverse breakdown to clamp or regulate voltage at ~3.6 V under controlled current. Its low dynamic impedance (90 Ω @ 5 mA) ensures stable regulation across load variations, while its 0.9 mm body height supports ultra-thin portable designs.
Thermal resistance of 635 °C/W and derating of 1.5 mW/°C above 25°C define its thermal envelope; junction temperature must remain within −65 to +150°C. The cathode-anode polarity is marked by a band, and soldering is qualified to 260°C for 10 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4–3.8 V at IZT = 5 mA - defines regulation window for low-voltage rail clamping |
| Zener Impedance (ZZT) | 90 Ω max @ 5 mA - ensures minimal output voltage shift under dynamic load changes |
| Power Dissipation (PD) | 200 mW @ TA = 25°C - sets maximum continuous power handling on FR-5 board |
| Reverse Leakage (IR) | 5 µA max @ VR = 1.0 V - guarantees low standby current in bias/reference circuits |
| Temp Coefficient (αVZ) | −3.5 mV/°C - enables predictable drift compensation in temperature-sensitive references |
| Capacitance (C) | 450 pF max @ VR = 0, f = 1 MHz - impacts high-frequency noise filtering capability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6,115 | Same 3.6 V nominal Zener, but SOD-323 package with 400 mW PD rating and higher ZZT (120 Ω) | Higher power margin suits intermittent surge clamping; less suitable for continuous low-current bias | Select when sustained >10 mA regulation current or higher surge energy absorption is required |
| MMSZ3V6T1G | Identical electrical specs and SOD-123 package (2.7 × 1.4 mm), 500 mW PD, same −3.5 mV/°C tempco | Larger footprint accommodates higher thermal mass; not drop-in compatible due to different pad layout | Choose for legacy board redesigns where SOD-123 pads exist and thermal headroom is prioritized over size |
Compared with BZX384-B3V6,115 and MMSZ3V6T1G, the MM3Z3V6T1 delivers optimal balance of miniaturization, low-impedance regulation, and Class 3 ESD robustness - making it preferred for new designs targeting <1.0 mm² component area and sub-10 mA reference currents.

FAQ
What is the Zener voltage tolerance of MM3Z3V6T1 at 5 mA test current?
The MM3Z3V6T1 has a guaranteed Zener voltage range of 3.4 V to 3.8 V when tested at IZT = 5 mA and TA = 25°C. This ±0.2 V tolerance reflects its nominal 3.6 V rating and ensures predictable clamping behavior in low-voltage reference circuits. The MM3Z3V6T1 datasheet specifies this range in the Electrical Characteristics table on page 2.
Does MM3Z3V6T1 support Pb-free soldering processes?
Yes, the MM3Z3V6T1 is available in a Pb-free package (indicated by the "G" suffix), with leads plated in pure tin. It is qualified for reflow soldering at 260°C for 10 seconds, meeting JEDEC J-STD-020 moisture sensitivity level 1 requirements. The MM3Z3V6T1 G variant complies with RoHS Directive 2011/65/EU and REACH SVHC regulations.
What is the maximum reverse leakage current for MM3Z3V6T1 at 1.0 V?
The MM3Z3V6T1 exhibits a maximum reverse leakage current of 5 µA when biased at VR = 1.0 V and TA = 25°C. This low leakage ensures minimal parasitic loading in high-impedance bias networks and preserves battery life in always-on sensor nodes. The value is specified in the Electrical Characteristics table for the MM3Z3V6T1 device marking "06".
Can MM3Z3V6T1 be used as a substitute for MM3Z3V3T1 in a 3.3 V reference circuit?
No - the MM3Z3V6T1 is not a direct substitute for MM3Z3V3T1 because its Zener voltage range (3.4–3.8 V) exceeds the 3.1–3.5 V range of MM3Z3V3T1. Using MM3Z3V6T1 in a 3.3 V design risks overvoltage stress on downstream logic. The MM3Z3V6T1 should only replace MM3Z3V3T1 after verifying system-level tolerance to +0.3 V offset and recalculating current-limiting resistor values.
What is the thermal resistance (RJA) of MM3Z3V6T1 on an FR-5 board?
The MM3Z3V6T1 has a junction-to-ambient thermal resistance of 635 °C/W when mounted on an FR-5 printed circuit board at TA = 25°C. This value governs its power derating curve: dissipation must be reduced by 1.5 mW per °C above 25°C ambient. The MM3Z3V6T1 datasheet confirms this in the Maximum Ratings table on page 1.
