Product details

Overview

MM3Z6V2T1GX from Nexperia is a Zener voltage regulator diode in SOD323 (SC-76) package, designed for precision low-power voltage reference and regulation at 6.2 V nominal Zener voltage with ±5 % tolerance, 0.5 Ω differential resistance at I_Z = 5 mA, and 300 mW total power dissipation. It operates across −55 °C to +150 °C ambient and supports general-purpose regulation in space-constrained consumer and industrial PCBs.

For engineers reviewing the MM3Z6V2T1GX datasheet, MM3Z6V2T1GX pinout, MM3Z6V2T1GX application, or MM3Z6V2T1GX equivalent, this page delivers verified electrical characteristics, thermal behavior, cathode/anode terminal mapping, real-world use cases in voltage clamping and reference circuits, and validated alternative parts with documented parameter-level differences.

Technical Context

This device functions as a two-terminal shunt voltage regulator, maintaining stable output voltage by conducting reverse current above its specified Zener breakdown threshold. Its low 0.5 Ω dynamic impedance ensures minimal voltage deviation under load variation at 5 mA test current, while the negative-to-positive temperature coefficient transition near 6.2 V enables improved thermal stability in mid-range Zener voltages.

The SOD323 package provides surface-mount compatibility with FR4 PCBs using standard reflow profiles, and its 415 K/W junction-to-ambient thermal resistance reflects performance on single-sided copper layouts. The cathode-marked anode-cathode configuration supports unidirectional clamping and reference biasing in analog signal chains and power supply feedback networks.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	5.86 V to 6.53 V at I_Z = 5 mA - defines regulated output range under nominal bias
Differential Resistance (r_diff)	0.5 Ω max at I_Z = 5 mA - ensures tight voltage regulation against current fluctuations
Power Dissipation (P_tot)	300 mW at T_amb = 25 °C - sets maximum continuous DC power handling on standard FR4 layout
Forward Voltage (V_F)	1.1 V max at I_F = 100 mA - limits forward conduction loss in protection or bias paths
Reverse Current (I_R)	80 µA max at V_R = 4.5 V - quantifies leakage below breakdown, critical for low-power standby circuits
Temperature Coefficient (S_Z)	+0.4 mV/K to +3.7 mV/K - indicates positive drift with temperature, enabling compensation in reference designs
Junction Temperature (T_j)	150 °C max - defines absolute thermal limit for reliable long-term operation

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX384-B6V2,115 (Nexperia)	Same 6.2 V nominal, ±5 %, but in smaller SOD323 variant with tighter 0.4 Ω r_diff; 250 mW P_tot	Lower power rating reduces margin in sustained clamp scenarios; identical footprint enables drop-in replacement	Select when board space is identical and thermal budget allows reduced dissipation
1N4735A (ON Semiconductor)	6.2 V nominal, ±5 %, but in DO-35 axial package; 1.0 Ω r_diff, 1 W P_tot, higher thermal mass	Through-hole mounting requires PCB redesign; superior surge handling but incompatible with automated SMT assembly	Select only for prototyping or legacy through-hole systems requiring higher pulse robustness

Compared with BZX384-B6V2,115, MM3Z6V2T1GX offers 50 mW higher continuous power margin; versus 1N4735A, it enables miniaturized SMT integration but trades off surge endurance and thermal inertia.

FAQ

What is the maximum continuous reverse current the MM3Z6V2T1GX can sustain without exceeding its power rating?

At 25 °C ambient on a standard FR4 PCB, the device sustains up to 48.4 mA continuously (300 mW ÷ 6.2 V), assuming nominal Zener voltage. Derating applies above 25 °C per its 415 K/W thermal resistance; at 85 °C ambient, maximum safe DC current drops to approximately 29 mA to maintain T_j ≤ 150 °C.

How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?

With a specified +0.4 to +3.7 mV/K coefficient, V_Z increases by ~250 mV across a 125 K span. At 5 mA bias, this yields a worst-case shift of ±157 mV (±2.5 % of 6.2 V) over full range-acceptable for non-precision references but requiring compensation in metrology-grade designs.

Can MM3Z6V2T1GX be used in AC signal clipping applications?

Yes: its symmetrical forward (1.1 V @ 100 mA) and reverse (6.2 V) conduction thresholds enable bidirectional clipping. However, forward current must stay below 200 mA (absolute max), and thermal limits require pulsed operation above 10 mA average to avoid exceeding 300 mW dissipation on standard PCBs.

Is the SOD323 package compatible with standard reflow soldering profiles for lead-free assembly?

Yes: Nexperia specifies compatibility with IPC/JEDEC J-STD-020D reflow profiles. Peak temperature must not exceed 260 °C for ≤10 seconds, with ramp rates ≤3 °C/s pre-peak. The 0.45 mm height and 0.6 mm pad spacing align with standard stencil apertures for type 3 solder paste.
