Nexperia USA Inc. MM5Z2V7T5GF

Overview

MM5Z2V7T5GF from Nexperia is a 2.7 V ±2 % Zener voltage regulator diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 20 Ω typical differential resistance at I_Z = 5 mA and −3.5 to 0 mV/K temperature coefficient - used for precision low-voltage reference and overvoltage clamping in space-constrained consumer and industrial power rails.

For engineers reviewing the MM5Z2V7T5GF datasheet, MM5Z2V7T5GF pinout, MM5Z2V7T5GF application, or MM5Z2V7T5GF equivalent, this page delivers verified electrical characteristics, thermal behavior, cathode/anode terminal mapping, and direct-fit alternatives for low-voltage Zener regulation in compact SMD designs.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable 2.7 V across its terminals under regulated current conditions (I_Z = 5 mA), with low dynamic impedance (20 Ω) ensuring minimal output voltage variation with load changes. Its SC-79 package enables high-density PCB layouts while supporting reflow soldering per JEDEC J-STD-020.

The device exhibits a negative temperature coefficient (−3.5 to 0 mV/K), meaning its Zener voltage decreases slightly as junction temperature rises - a critical factor when designing temperature-stable references or clamps in ambient-variable environments.

FAQ

What is the maximum continuous reverse current (I_Z) for stable 2.7 V regulation?

The MM5Z2V7T5GF achieves specified Zener voltage and differential resistance at I_Z = 5 mA, with absolute maximum I_Z limited by P_tot = 300 mW. At 2.75 V, this yields ~109 mA max continuous reverse current - however, thermal derating applies above 25 °C ambient, and 5–20 mA is recommended for stable regulation and minimal self-heating.

Can MM5Z2V7T5GF be used in forward conduction mode?

Yes - its forward voltage is 1.1 V max at 100 mA, making it usable as a low-drop rectifier or polarity protection diode. However, its primary design intent is reverse-bias Zener operation; forward conduction should be limited to brief pulses or low-duty-cycle applications to avoid exceeding P_tot and thermal limits.

How does the −3.5 to 0 mV/K temperature coefficient affect circuit accuracy?

This coefficient means the Zener voltage decreases by up to 3.5 mV per Kelvin rise in junction temperature. Over a 100 °C range (−40 to +60 °C), V_Z may drop by up to 350 mV - so system-level thermal management or compensation (e.g., using complementary tempcos) is required for sub-1 % accuracy across temperature.

Is the SOD523 package compatible with standard automated assembly processes?

Yes - the SOD523 (SC-79) package is fully compatible with IPC-7351B-compliant reflow profiles, J-STD-020 moisture sensitivity level 1, and standard 0402-sized pick-and-place nozzles. Its flat lead geometry ensures reliable solder joint formation and coplanarity control on fine-pitch PCBs.
