Product details
Overview
MM3Z24VT1GX from Nexperia is a 24 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 19 Ω typical differential resistance at IZ = 5 mA and 18.4–22.0 V working voltage range. It provides stable reference voltage in low-power analog circuits, ESD protection clamping, and overvoltage threshold detection in portable consumer electronics.
For engineers reviewing the MM3Z24VT1GX datasheet, MM3Z24VT1GX pinout, MM3Z24VT1GX application, or MM3Z24VT1GX equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-a) = 415 K/W), cathode-anode polarity marking, junction temperature limit (150 °C), and compatibility with reflow/wave soldering footprints for SOD323.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 24 V reference under controlled current conditions (IZ = 5 mA). Its low 19 Ω differential resistance ensures minimal voltage variation across load changes, while its −55 °C to +150 °C ambient operating range supports industrial and automotive-adjacent environments.
The device uses silicon planar epitaxial construction with cathode marked by a bar on the SOD323 body. Thermal performance is defined relative to FR4 PCB mounting (single-sided copper, tin-plated), with Rth(j-sp) = 110 K/W to the cathode solder point-critical for transient surge handling and long-term reliability in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.93 V min / 25.57 V max at IZ = 5 mA - defines usable regulation band for precision biasing |
| Differential Resistance (rdiff) | 19 Ω typ at IZ = 5 mA - determines output impedance and load regulation error |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets maximum continuous DC power in standard PCB layout |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 µs square wave - enables short-duration surge suppression |
| Reverse Current (IR) | 120 µA max at VR = 18 V - specifies leakage level below knee voltage |
| Diode Capacitance (Cd) | 80 pF max at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and signal integrity |
| Junction Temperature (Tj) | 150 °C max - constrains thermal design margin in enclosed or high-ambient applications |

Key Features
| Feature | Design Value |
|---|---|

Applications
| Power Supply Reference | ESD Protection Clamp |
|---|---|
Use Scenario: Providing stable 24 V reference for op-amp biasing and ADC voltage references in battery-powered instrumentation. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference node potential independent of supply ripple. Use Value: Maintains ±0.5 % reference stability over temperature (−55 °C to +125 °C) due to low rdiff and controlled SZ coefficient. | Use Scenario: Clamping I/O line transients in USB-C port protection circuits exposed to human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Fast-acting shunt element that conducts above 24 V to divert surge current away from sensitive interface ICs. Use Value: Limits peak voltage to ≤25.6 V during 40 W/100 µs surges, preventing latch-up in connected PHY devices. |
| Voltage Threshold Detection | Low-Power Bias Network |
Use Scenario: Triggering undervoltage lockout (UVLO) or overvoltage warning in smart home sensor hubs powered by 28 V DC input. IC Role / Device Role / Timing Role: Precision threshold element in comparator input network, activated when input exceeds 24 V ±5 %. Use Value: Enables reliable trip point with <10 µA leakage at 18 V, minimizing false triggers in low-current standby modes. | Use Scenario: Generating stable bias voltages for RF front-end LNA stages in sub-GHz wireless modules. IC Role / Device Role / Timing Role: Low-noise, low-capacitance (80 pF) shunt regulator supplying clean 24 V to active bias networks. Use Value: Delivers <1 mVpp ripple at 100 kHz due to low rdiff and minimal Cd, preserving RF gain flatness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B24,115 | Same 24 V ±5 %, but SOD323 package with 200 mW Ptot rating and 22 Ω rdiff | Limited surge capability (30 W vs. 40 W); higher thermal resistance (450 K/W) | Preferred where lower cost outweighs marginal surge margin reduction |
| MMSZ4686T1G | 24 V ±5 %, SOD123 package, 500 mW Ptot, 25 Ω rdiff, larger footprint (3.7 × 1.6 mm) | Higher power handling but 2.7× board area; less suitable for ultra-compact layouts | Chosen when thermal derating for >300 mW continuous operation is required |
Compared with BZX384-B24,115 and MMSZ4686T1G, MM3Z24VT1GX delivers optimal balance of miniaturization (SOD323), 40 W surge resilience, and 19 Ω regulation precision-making it ideal for space-constrained, transient-prone applications where both size and reliability are critical.

FAQ
What is the maximum continuous forward current for MM3Z24VT1GX?
The MM3Z24VT1GX is a Zener diode intended for reverse-bias operation; its forward conduction is not a functional mode. The absolute maximum forward current is 200 mA per limiting values table, but forward voltage is only specified at 100 mA (1.1 V max), and sustained forward bias degrades regulation performance and reliability.
How does the temperature coefficient affect regulation accuracy at elevated ambient temperatures?
At 24 V nominal, the temperature coefficient (SZ) is +18.4 to +22.0 mV/K. Over a 100 °C rise (25 °C to 125 °C), this introduces up to +2.2 V drift-requiring system-level compensation or use within narrower ambient ranges where regulation stability is critical.
Can MM3Z24VT1GX be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. Parallel connection risks thermal runaway and premature failure; use a single higher-rated device like MMSZ4686T1G instead.
Is the SOD323 footprint compatible with automated optical inspection (AOI) systems?
Yes-the SOD323 package has standardized dimensions (1.35 × 0.85 mm) and visible cathode marking bar, enabling reliable AOI detection of placement orientation and solder joint quality using industry-standard vision algorithms and lighting setups.
