Product details
Overview
MM5Z3V6T5G from onsemi is a 3.6 V ±5% Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation at 25 °C, with 90 Ω max Zener impedance at 5 mA test current and 5 μA max reverse leakage at 1.0 V. It provides precision voltage regulation in space-constrained portable electronics.
For engineers reviewing the MM5Z3V6T5G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance (±5%), low-profile SOD-523 footprint (1.20 mm × 0.80 mm), ESD robustness (>16 kV HBM), thermal resistance (250 °C/W), and automotive-grade AEC-Q101 qualification availability via SZ prefix variants.
Technical Context
This device operates as a two-terminal voltage reference by exploiting controlled reverse breakdown in a silicon PN junction. Its regulation performance is defined at IZT = 5 mA with VZ = 3.4–3.8 V, and it maintains stable operation across −65 °C to +150 °C junction temperature range.
The SOD-523 package enables high-density PCB layout with minimal board area and low profile (0.7 mm height). Thermal derating begins above 25 °C at 4.0 mW/°C, supporting reliable operation in thermally constrained environments such as handheld portables.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C3V6 | 3.6 V ±5%, SOD-523, 300 mW rating, 120 Ω ZZT, no AEC-Q101 option | Limited to commercial-temp industrial use; lower power margin reduces surge handling capability | Select when cost sensitivity outweighs power headroom and automotive qualification needs |

FAQ
What is the Zener voltage tolerance of MM5Z3V6T5G?
The MM5Z3V6T5G has a nominal Zener voltage of 3.6 V with a standard tolerance of ±5%, meaning its actual breakdown voltage falls between 3.4 V and 3.8 V when tested at 5 mA (IZT). This tolerance is confirmed in the Electrical Characteristics table on page 3 of the onsemi datasheet, and applies across the full operating temperature range of −65 °C to +150 °C.
Is MM5Z3V6T5G suitable for automotive applications?
Yes - the MM5Z3V6T5G itself is qualified for commercial and industrial use; however, its automotive-grade counterpart SZMM5Z3V6T5G is AEC-Q101 qualified and PPAP capable. The SZ prefix variant undergoes additional stress testing and process controls required for automotive body electronics and infotainment systems, while maintaining identical electrical specs and SOD-523 packaging as MM5Z3V6T5G.
What is the maximum power dissipation of MM5Z3V6T5G at 75 °C ambient?
At 75 °C ambient, MM5Z3V6T5G's maximum power dissipation is 300 mW. This is calculated using the derating factor of 4.0 mW/°C from the datasheet: 500 mW − (75 − 25) × 4.0 mW = 300 mW. The device remains within safe operating limits up to +150 °C junction temperature, provided PCB copper area and airflow meet FR-4 single-sided pad guidelines.
Does MM5Z3V6T5G have a specified temperature coefficient?
Yes - MM5Z3V6T5G has a maximum temperature coefficient of −3.5 mV/°C at IZT = 5 mA, indicating its Zener voltage decreases slightly with rising temperature. This value is listed in the Electrical Characteristics table and reflects typical behavior for low-voltage Zeners below 5 V; it enables predictable drift modeling in precision reference circuits.
What is the reverse leakage current specification for MM5Z3V6T5G?
The reverse leakage current for MM5Z3V6T5G is specified as 5 μA maximum at 1.0 V reverse voltage (VR) and 25 °C ambient. This low leakage supports energy-sensitive applications like battery-backed sensors and always-on IoT nodes, where standby current must remain below microampere thresholds to extend operational life.
