Product details
Overview
MM5Z5V6T1 from onsemi is a 5.6 V ±5% Zener diode in SOD−523 package, rated for 100 mW steady-state power dissipation, with 40 Ω maximum Zener impedance at 5 mA test current and 1 μA reverse leakage at 2 V. It provides precision voltage regulation in space-constrained portable electronics such as smartphone power rails and USB interface protection circuits.
For engineers reviewing the MM5Z5V6T1 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal limits, ESD robustness (Class 3, >16 kV HBM), package dimensions, and real-world use cases aligned to ON Semiconductor's official MM5Z2V4T1 series specification.
Technical Context
The MM5Z5V6T1 operates as a two-terminal voltage reference device, conducting in reverse bias above its nominal Zener voltage of 5.6 V with tightly controlled tolerance (5.2–6.0 V). Its low 0.7 mm body height and 1.20 mm × 0.80 mm footprint enable integration into ultra-dense PCB layouts where board area is constrained.
It exhibits a temperature coefficient of −2.0 mV/°C over its operating range (−65 °C to +150 °C), ensuring stable regulation across industrial ambient conditions. The device uses void-free thermosetting plastic packaging with 100% matte tin lead finish and meets MSL 1 reflow requirements up to 260 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C5V6 | Same 5.6 V nominal, but SOD-323 package (1.7 × 1.3 mm); 500 mW rating; higher ZZT (90 Ω) | Less space-constrained designs; higher power surge handling required | Select when board layout allows larger footprint and >100 mW transient absorption is needed |
| MMSZ5232BT1G | SOD-123 package (3.7 × 1.6 mm); 500 mW rating; wider VZ tolerance (±5.8%); 100 Ω ZZT | Legacy designs with existing SOD-123 footprints; cost-sensitive volume production | Choose for drop-in replacement in legacy boards where size penalty is acceptable |
Compared with BZX584C5V6 and MMSZ5232BT1G, the MM5Z5V6T1 offers the smallest PCB footprint and lowest profile while maintaining tight regulation and high ESD robustness-making it optimal for next-generation miniaturized consumer and IoT endpoints where space and reliability are co-constrained.

FAQ
What is the nominal Zener voltage and tolerance of the MM5Z5V6T1?
The MM5Z5V6T1 has a nominal Zener voltage of 5.6 V with a guaranteed range of 5.2 V to 6.0 V at 5 mA test current (IZT), corresponding to ±5% tolerance. This specification is validated per the official ON Semiconductor MM5Z2V4T1 series datasheet Rev. 2, July 2004, and applies directly to the MM5Z5V6T1 device marking code "0C".
Does the MM5Z5V6T1 support automated SMT assembly?
Yes, the MM5Z5V6T1 is qualified for standard reflow soldering with a maximum peak temperature of 260 °C and meets MSL 1 moisture sensitivity level requirements. Its SOD−523 package features 100% matte tin leads and is compatible with Type 3 solder paste and standard pick-and-place equipment used in high-volume electronics manufacturing.
What is the maximum reverse leakage current for the MM5Z5V6T1 at 2 V?
The MM5Z5V6T1 specifies a maximum reverse leakage current (IR) of 1 μA at VR = 2 V, measured at TA = 25 °C. This value is confirmed in the Electrical Characteristics table on page 3 of the official datasheet and reflects the device's low standby power consumption in clamping or reference configurations.
Can the MM5Z5V6T1 be used for bidirectional ESD protection?
No-the MM5Z5V6T1 is a unidirectional Zener diode optimized for reverse-bias voltage regulation. For bidirectional ESD protection (e.g., on USB data lines), it must be paired with a second MM5Z5V6T1 in series opposition or replaced with a dedicated bidirectional TVS device; the datasheet does not specify forward conduction beyond VF ≤ 0.9 V @ 10 mA.
What is the thermal resistance junction-to-ambient (RθJA) for the MM5Z5V6T1 on FR-5 board?
The MM5Z5V6T1 datasheet does not publish RθJA as a discrete parameter. However, its 100 mW power rating is explicitly specified for operation on FR-5 board at TA = 25 °C, implying a thermal design limit consistent with typical SOD−523 devices (~400–500 °C/W). Derating curves or board-specific thermal modeling are required for elevated ambient temperatures.
