Nexperia USA Inc. MM5Z2V4T5GF

Overview

MM5Z2V4T5GF from Nexperia is a general-purpose Zener diode in SOD523 (SC-79) package, designed for precision voltage regulation and reference functions at 2.4 V nominal Zener voltage with ±2 % tolerance, 50 Ω typical differential resistance at I_Z = 5 mA, and 300 mW total power dissipation. It operates in low-power analog circuits, voltage clamping, and biasing applications where compact size and stable reverse breakdown are critical.

For engineers reviewing the MM5Z2V4T5GF datasheet, MM5Z2V4T5GF pinout, MM5Z2V4T5GF application, or MM5Z2V4T5GF equivalent, this device serves as a surface-mount voltage reference with verified thermal resistance (R_th(j-a) = 350 K/W), low forward voltage (1.1 V @ 100 mA), and defined non-repetitive surge capability (40 W @ 100 µs).

Technical Context

This Zener diode operates in reverse-biased breakdown mode to maintain a stable 2.35–2.45 V reference across load variations, with temperature coefficient of −3.5 to 0 mV/K and reverse current ≤400 µA at V_R = 1 V. Its low 50 Ω differential resistance ensures minimal voltage drift under dynamic current changes.

The SOD523 package enables high-density PCB layouts while supporting reflow soldering per JEDEC J-STD-020. Junction-to-solder-point thermal resistance is 65 K/W, enabling reliable operation up to 150 °C junction temperature when mounted on FR4 with 35 mm² copper area at cathode tab.

FAQ

What is the maximum continuous reverse current the MM5Z2V4T5GF can sustain at 25 °C ambient?

The MM5Z2V4T5GF sustains up to 125 mA continuous reverse current at 25 °C ambient, calculated from its 300 mW total power dissipation and 2.4 V nominal Zener voltage (P = V × I → I = 300 mW / 2.4 V ≈ 125 mA). This assumes adequate PCB copper area (35 mm² at cathode) to maintain junction temperature within 150 °C limit.

How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

With a specified temperature coefficient of −3.5 to 0 mV/K, the MM5Z2V4T5GF exhibits a worst-case Zener voltage shift of −0.875 V over a 250 K range (−40 °C to +125 °C), but actual drift is bounded by test conditions: typical shift is <±50 mV across that range due to nonlinear behavior and low-current operation (I_Z = 5 mA), confirmed in Figure 4 of the datasheet.

Can MM5Z2V4T5GF be used in forward-bias mode for LED driver current setting?

Yes - its forward voltage is characterized at 1.1 V @ 100 mA (pulse-tested), making it usable as a low-drift current-setting element in constant-current LED bias networks. However, forward conduction is not its primary function; sustained DC forward current above 200 mA exceeds absolute maximum rating and risks thermal runaway without active cooling.

Is the SOD523 package compatible with standard reflow profiles for lead-free soldering?

Yes - the SOD523 footprint matches JEDEC J-STD-020 requirements for small-outline diodes. The recommended reflow profile uses peak temperature ≤260 °C for ≤10 seconds, with ramp rates ≤3 °C/s, as validated in Nexperia's SOD523 soldering guidelines (Figure 10). Thermal resistance data confirms safe operation under these conditions when mounted per specified land pattern.
