Nexperia USA Inc. MM5Z6V2T5GF

Overview

MM5Z6V2T5GF from Nexperia is a precision Zener voltage regulator diode in SOD523 (SC-79) package, designed for low-power voltage reference and regulation in space-constrained applications. It delivers a nominal 6.2 V Zener voltage with ±2 % tolerance, 3.0 Ω differential resistance at I_Z = 5 mA, and operates with ≤300 mW total power dissipation at T_amb = 25 °C - used in biasing circuits, overvoltage clamping, and analog signal conditioning.

For engineers reviewing the MM5Z6V2T5GF datasheet, MM5Z6V2T5GF pinout, MM5Z6V2T5GF application, or MM5Z6V2T5GF equivalent, key selection criteria include Zener voltage accuracy, low r_diff, thermal resistance (R_th(j-sp) = 65 K/W), cathode-anode polarity marking, and SOD523 footprint compatibility with high-density PCB layouts.

Technical Context

This Zener diode functions as a two-terminal shunt voltage reference, maintaining stable reverse breakdown at 6.2 V under regulated current conditions (I_Z = 5 mA). Its temperature coefficient is +0.4 mV/K, indicating slight positive drift over temperature - optimal for mid-range voltage references where moderate TC is acceptable.

The device exhibits low junction-to-solder-point thermal resistance (65 K/W), enabling reliable operation on FR4 PCBs with ~35 mm² copper area at the cathode tab. Non-repetitive peak reverse power handling is rated at 40 W (t_p = 100 µs, square wave), supporting transient surge suppression in low-energy protection paths.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous reverse current for stable Zener operation?

The MM5Z6V2T5GF is rated for continuous Zener current up to 48 mA at 6.2 V to maintain ≤300 mW dissipation (P = V × I). At 25 °C ambient on FR4 with 35 mm² copper, sustained operation above this level risks exceeding T_j = 150 °C and degrading long-term reliability.

How does the +0.4 mV/K temperature coefficient affect circuit accuracy over −40 °C to +85 °C?

Over that range, the Zener voltage shifts by +25 mV (0.4 mV/K × 62.5 K), resulting in a final V_Z of 6.345 V max. This represents +2.3 % deviation from nominal - acceptable for non-critical references but insufficient for metrology-grade applications requiring <±0.1 % stability.

Can MM5Z6V2T5GF be used in place of a 6.3 V Zener diode?

No - its guaranteed V_Z range is 6.08 V to 6.32 V at 5 mA, meaning it may fall below 6.3 V in production. For strict 6.3 V compliance, MM5Z6V8T5GF (6.66–6.94 V) or MM5Z6V2T5G variants with tighter binning would be required, but no 6.3 V part exists in this series.

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

Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D reflow profiles. The recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s pre-peak. Figure 10 in the datasheet provides the exact solder land pattern (1.4 × 0.4 mm pads, 0.5 mm spacing) for reliable joint formation.
