Product details
Overview
MM5Z16VT5GF from Nexperia is a 16 V ±2 % tolerance Zener diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 11.2 Ω differential resistance at IZ = 11.2 mA and 10.4 mV/K temperature coefficient - used for precision voltage reference and low-power regulation in space-constrained consumer and industrial PCBs.
For engineers reviewing the MM5Z16VT5GF datasheet, MM5Z16VT5GF pinout, MM5Z16VT5GF application, or MM5Z16VT5GF equivalent, this page delivers verified Zener parameters, cathode/anode terminal mapping, thermal resistance (65 K/W to solder point), forward voltage (1.1 V @ 100 mA), and real-world regulation use cases - all confirmed from Nexperia's official Rev. 2 product data sheet dated 6 August 2026.
Technical Context
This Zener operates in reverse-bias breakdown mode with a nominal 16 V working voltage (15.68–16.32 V range), delivering stable regulation under DC or low-frequency transient conditions. Its 0.05 %/°C temperature coefficient slope and 11.2 Ω dynamic impedance ensure predictable voltage stability across load and temperature variations.
The device uses a planar silicon junction structure optimized for low leakage (<10 µA @ 12.8 V) and fast response to step-load changes. Thermal design relies on its 65 K/W junction-to-solder-point resistance, requiring minimal copper area (35 mm² at cathode tab) for reliable 300 mW continuous operation at Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 15.68 V to 16.32 V at IZ = 11.2 mA - defines regulation setpoint with ±2 % tolerance for precision biasing |
| Differential Resistance rdiff | 11.2 Ω - determines output impedance and load regulation error (ΔVZ ≈ 11.2 mV per 1 mA load change) |
| Temperature Coefficient SZ | 10.4 mV/K - quantifies VZ drift over temperature; enables compensation in reference circuits |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C on FR4 with 35 mm² cathode copper - sets maximum continuous DC power handling |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 µs square wave - supports ESD/surge clamping in transient protection paths |
| Forward Voltage VF | 1.1 V at IF = 100 mA - defines conduction loss when used as series diode or in dual-Zener configurations |
| Junction Temperature Tj | 150 °C maximum - constrains thermal design margin when operating near Ptot limit |
Pinout & Package
SOD523 (SC-79) ultra-small surface-mount plastic package: 1.25 mm × 0.85 mm footprint, 0.65 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse current during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path; serves as thermal anchor via solder point |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C16 | Same 16 V nominal, ±2 %, but in SOD323 package (larger footprint, 220 mW Ptot) | Higher thermal mass suits higher ambient temp environments (>85 °C), but incompatible with ultra-dense layouts | Select when board-level thermal management prioritizes reliability over size; not drop-in due to different land pattern |
| MMSZ5245B | 16 V nominal, ±5 % tolerance, 500 mW Ptot, SOD123 package | Looser tolerance increases reset threshold uncertainty; higher power rating allows higher current biasing | Choose for cost-sensitive industrial controls where ±5 % regulation is acceptable and PCB space permits larger SOD123 |
Compared with BZX584C16 and MMSZ5245B, MM5Z16VT5GF offers the smallest footprint (SOD523), tightest tolerance (±2 %), and optimal balance of surge capability (40 W) and thermal performance (65 K/W) for miniaturized, precision-regulated systems.

FAQ
What is the maximum continuous reverse current for stable Zener operation?
The MM5Z16VT5GF maintains regulation up to 18.75 mA continuous reverse current, calculated from its 300 mW power rating divided by 16 V nominal Zener voltage. Operation beyond this current risks exceeding the 150 °C junction temperature limit unless PCB copper area exceeds 35 mm² at the cathode tab.
How does the 10.4 mV/K temperature coefficient affect long-term voltage accuracy?
Over a −40 °C to +125 °C ambient range, the Zener voltage shifts by approximately ±1.7 V due to the 10.4 mV/K coefficient. For applications requiring sub-1 % stability, external temperature compensation or selection of a zero-TC Zener (e.g., 5.6 V type) is necessary - this part is optimized for moderate-accuracy, size-constrained use.
Can MM5Z16VT5GF be used in bidirectional ESD protection?
No - it is a unidirectional Zener diode. Bidirectional protection requires two devices in series opposition (anode-to-anode or cathode-to-cathode) or a dedicated bidirectional TVS. Using a single MM5Z16VT5GF only clamps negative transients relative to ground; positive surges would forward-bias the diode and offer no protection.
Is the SOD523 package compatible with standard reflow profiles?
Yes - the SOD523 outline matches JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. The recommended solder land pattern (1.4 mm × 0.5 mm pads, 0.4 mm gap) is defined in Figure 10 of the datasheet and validated for void-free joint formation using Type 3 solder paste.
