Product details
Overview
MM5Z16VT5G from onsemi is a 16 V ±5% Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation, with 40 Ω maximum Zener impedance at 5 mA test current and 10.4 V temperature coefficient (mV/°C). It provides precision voltage regulation in space-constrained portable electronics such as smartphone power rails and USB interface protection.
For engineers reviewing the MM5Z16VT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 16.2 V nominal Zener voltage at 5 mA, 0.05 μA reverse leakage at 12.8 V, 105 pF capacitance at 0 V, ESD rating >16 kV HBM, and SOD-523 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage across load circuits. Its Zener mechanism delivers stable regulation under varying current conditions between 1 mA and 5 mA, with thermal coefficient of +11.2 mV/°C ensuring predictable drift over −65 °C to +150 °C junction temperature range.
The SOD-523 package enables surface-mount integration with minimal board area (1.20 mm × 0.80 mm) and low profile (0.7 mm height), while its 100% matte tin lead finish supports lead-free reflow up to 260 °C and meets MSL 1 moisture sensitivity requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C16LT1G | Same 16 V nominal, but ±1% tolerance and 30 Ω ZZT; SOD-523 package; lower leakage (0.01 μA @ 12.8 V) | Better regulation accuracy and lower noise - preferred for precision reference designs | Select BZX584C16LT1G when tighter voltage tolerance and lower dynamic impedance are required |
| MMSZ5245BT1G | 16 V nominal, ±5% tolerance, but SOD-123 package (2.7 × 1.6 mm); 500 mW rating; higher capacitance (150 pF) | Larger footprint and higher parasitic capacitance - suitable only where board space is not constrained | Choose MMSZ5245BT1G if legacy SOD-123 layout reuse is prioritized over miniaturization |
Compared with BZX584C16LT1G and MMSZ5245BT1G, the MM5Z16VT5G offers optimal balance of ultra-compact size, industry-standard ±5% tolerance, and proven reliability in high-volume portable electronics - making it the default choice for new SOD-523 designs requiring cost-effective 16 V regulation.

FAQ
What is the nominal Zener voltage and test current for MM5Z16VT5G?
The MM5Z16VT5G has a nominal Zener voltage of 16.2 V measured at a reverse test current (IZT) of 5 mA. This value falls within the guaranteed range of 15.3 V to 17.1 V at the same test condition, per the onsemi datasheet revision 19. The 5 mA test current reflects standard industry practice for characterizing 16 V-class Zeners and ensures repeatable measurement across production lots.
Does MM5Z16VT5G meet automotive qualification standards?
The MM5Z16VT5G is not AEC-Q101 qualified; however, its automotive-grade counterpart SZMM5Z16VT5G is explicitly certified to AEC-Q101 and PPAP capable. The MM5Z16VT5G shares identical electrical specifications and SOD-523 packaging but lacks the controlled manufacturing site and change control required for automotive use. For non-automotive industrial or consumer applications, MM5Z16VT5G remains fully suitable.
What is the maximum reverse leakage current specification for MM5Z16VT5G?
The MM5Z16VT5G specifies a maximum reverse leakage current (IR) of 0.05 μA at a reverse voltage (VR) of 12.8 V and ambient temperature of 25 °C. This ultra-low leakage ensures minimal quiescent current draw in battery-powered applications and preserves accuracy in high-impedance bias networks where even nanoamp-level currents affect performance.
Can MM5Z16VT5G be used for ESD protection in high-speed interfaces?
Yes, MM5Z16VT5G is suitable for ESD protection in high-speed interfaces such as USB 2.0 due to its low 105 pF capacitance at 0 V and >16 kV HBM ESD rating. Its SOD-523 footprint allows placement directly at connector entry points without significant signal degradation, and its 40 Ω dynamic impedance ensures rapid clamping response to fast-rising transients while maintaining signal integrity below 480 MHz.
What is the thermal resistance and derating behavior of MM5Z16VT5G?
The MM5Z16VT5G has a junction-to-ambient thermal resistance (RJA) of 250 °C/W on FR-4 board with 1 cm² copper pad. Its power rating derates linearly above 25 °C at 4.0 mW/°C, reaching zero dissipation at 150 °C. This derating curve is validated in Figure 1 of the onsemi datasheet and must be applied in thermal design for sustained operation in enclosed or high-ambient environments.
