Nexperia USA Inc. MM3Z13VT1GX

Overview

MM3Z13VT1GX from Nexperia is a 13 V ±5 % Zener voltage regulator diode in SOD323 (SC-76) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 10.0 Ω typical differential resistance at I_Z = 5 mA and 7.0 mV/K temperature coefficient at I_Z = 5 mA - used for precision low-power voltage reference and overvoltage clamping in sensor signal conditioning circuits.

For engineers reviewing the MM3Z13VT1GX datasheet, MM3Z13VT1GX pinout, MM3Z13VT1GX application, or MM3Z13VT1GX equivalent, this page delivers verified electrical characteristics, thermal behavior, cathode/anode terminal mapping, and direct-fit alternatives for stable 13 V regulation in space-constrained PCB designs.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 13 V reference across load variations, with low 10.0 Ω differential resistance ensuring minimal voltage shift under ±1 mA current change. Its 7.0 mV/K temperature coefficient reflects moderate thermal drift, requiring layout-aware thermal coupling for high-stability references.

The device supports pulsed surge handling up to 40 W (t_p = 100 µs), while continuous operation is limited to 300 mW at T_amb = 25 °C on FR4 PCB. Junction-to-ambient thermal resistance is 415 K/W, confirming suitability only for low-duty-cycle or thermally managed applications.

FAQ

What is the maximum continuous reverse current for stable 13 V regulation?

The MM3Z13VT1GX maintains regulation within specification up to 10 mA continuous reverse current, derived from its 300 mW power limit (P = V × I → 300 mW ÷ 13 V ≈ 23 mA), but derated to 10 mA to ensure thermal stability on standard FR4 PCBs with 415 K/W junction-to-ambient resistance.

Can MM3Z13VT1GX replace MM3Z12VT1GX in a 12 V circuit without redesign?

No - the MM3Z13VT1GX has a minimum Zener voltage of 12.47 V, exceeding the 12 V nominal requirement; using it risks undershooting regulation in low-current conditions and may cause downstream ICs to brown out if their 12 V supply tolerance is tight (e.g., ±3 %). A 12 V part must be selected for guaranteed compliance.

How does the 7.0 mV/K temperature coefficient impact long-term reference stability?

A 7.0 mV/K coefficient means the Zener voltage shifts +7 mV per °C rise in junction temperature; over a 100 °C range (−40 °C to +60 °C ambient), this yields ~700 mV drift - requiring either thermal isolation, active compensation, or system-level calibration to maintain sub-1 % accuracy in precision references.

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

Yes - the MM3Z13VT1GX's SOD323 package is qualified for JEDEC J-STD-020D reflow profiles, with peak temperatures up to 260 °C for ≤ 30 seconds; the recommended solder land pattern (0.6 mm × 0.5 mm pads, 0.95 mm pitch) ensures reliable wetting and mechanical attachment without tombstoning.
