Product details
Overview
MM3Z16VT1GX from Nexperia is a 16 V ±5 % tolerance Zener diode in SOD323 (SC-76) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 12 Ω typical differential resistance at IZ = 5 mA and 10.4 mV/K temperature coefficient at IZ = 5 mA - used for precision voltage reference and low-power regulation in space-constrained consumer and industrial PCBs.
For engineers reviewing the MM3Z16VT1GX datasheet, MM3Z16VT1GX pinout, MM3Z16VT1GX application, or MM3Z16VT1GX equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-a) = 415 K/W), cathode/anode polarity marking, junction temperature limit (150 °C), and SOD323 footprint compatibility with automated reflow assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 16 V output across load and line variations, with low dynamic impedance enabling tight regulation under transient current changes. Its 0.05 %/°C voltage drift over temperature is specified at IZ = 5 mA, supporting stable biasing in analog sensor interfaces and reference circuits.
The device uses planar epitaxial silicon construction with metallized cathode termination, optimized for high surge immunity (40 W, tp = 100 µs) and low capacitance (97 pF at f = 1 MHz, VR = 0 V), making it suitable for noise-sensitive signal conditioning paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.37 V to 17.09 V at IZ = 5 mA - defines nominal regulation point with ±5 % tolerance band |
| Differential Resistance (rdiff) | 12 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | 10.4 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius for thermal stability analysis |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous DC power handling capability |
| Non-repetitive Peak Reverse Power | 40 W at tp = 100 µs, square wave - defines surge energy withstand for ESD/transient protection roles |
| Junction-to-Ambient Thermal Resistance | 415 K/W in free air - determines temperature rise under steady-state power, critical for derating |
| Reverse Current (IR) | ≤ 20 µA at VR = 12.8 V - ensures low leakage below knee voltage in standby circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B16,115 | Same 16 V nominal, ±5 % tolerance, but SOD323 package with 15 Ω rdiff and 11.5 mV/K SZ | Higher differential resistance increases load regulation error; slightly higher tempco reduces thermal stability | Select when legacy BOM alignment required; verify rdiff impact on worst-case error budget |
| MMSZ5245B-TP | 16 V nominal, ±5 %, but SOD123 package (larger footprint), 17 Ω rdiff, 10.5 mV/K SZ, 500 mW Ptot | Larger thermal mass improves power handling but occupies 2.5× board area; higher Ptot suits higher-current biasing | Choose for designs needing >300 mW continuous dissipation or existing SOD123 land patterns |
Compared with BZX384-B16,115 and MMSZ5245B-TP, MM3Z16VT1GX offers the lowest differential resistance (12 Ω) and smallest footprint (SOD323), making it optimal for space-constrained, high-accuracy voltage reference designs where thermal resistance (415 K/W) and surge rating (40 W) meet system-level reliability targets.

FAQ
What is the maximum continuous forward current for MM3Z16VT1GX?
The MM3Z16VT1GX is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per datasheet limiting values (Table 5). However, forward conduction is not its functional mode - sustained forward bias exceeds design intent and risks thermal overstress due to low thermal resistance and absence of forward-rated power derating curves.
Does MM3Z16VT1GX have AEC-Q200 qualification?
No, MM3Z16VT1GX is not AEC-Q200 qualified. Nexperia explicitly states in the legal disclaimers that unless a product is expressly marked automotive-qualified, it is not suitable for automotive use. This part is designated for general industrial and consumer applications, with no automotive stress testing or qualification documentation provided.
How does the 10.4 mV/K temperature coefficient affect circuit accuracy over temperature?
At IZ = 5 mA, the +10.4 mV/K coefficient means the Zener voltage increases by ~10.4 mV per °C rise. Over a 100 °C range (−40 °C to +60 °C), this yields ~1.04 V drift - a 6.5 % change relative to 16 V. Designers must either compensate via circuit topology (e.g., complementary diodes) or restrict ambient operating range to maintain <1 % regulation error.
Can MM3Z16VT1GX replace MM3Z15VT1G in an existing design?
Direct substitution is not recommended without validation: MM3Z16VT1GX has 16 V nominal Zener voltage (15.37–17.09 V), while MM3Z15VT1G is 15 V (13.84–15.52 V). The 1 V shift alters regulation point, affecting downstream biasing, reference accuracy, and overvoltage thresholds - requiring recalculating load current, power dissipation, and thermal margin for the new voltage level.
