Product details
Overview
MM5Z24VT5GF from Nexperia is a 24 V ±2 % tolerance Zener diode in SOD523 (SC-79) package, rated for 300 mW total power dissipation and 40 W non-repetitive peak reverse power, with 16.8 Ω differential resistance at IZ = 5 mA and −18.4 to +22.0 mV/K temperature coefficient - used for precision voltage reference and overvoltage clamping in low-power analog sensor interfaces.
For engineers reviewing the MM5Z24VT5GF datasheet, MM5Z24VT5GF pinout, MM5Z24VT5GF application, or MM5Z24VT5GF equivalent, this device serves as a compact, stable shunt regulator in space-constrained DC biasing, ESD protection feedback paths, and low-current reference circuits where thermal resistance (Rth(j-a) = 350 K/W) and cathode-marked polarity are critical layout considerations.
Technical Context
This Zener operates in reverse breakdown with a nominal 24 V regulation voltage at 5 mA test current, maintaining tight ±2 % tolerance across production lots. Its low 16.8 Ω dynamic impedance ensures minimal output voltage shift under load variation in reference divider networks.
The device exhibits a negative-to-positive temperature coefficient range (−18.4 to +22.0 mV/K), enabling predictable drift compensation in temperature-sensitive analog stages. It supports pulsed surge handling up to 40 W (100 µs square wave) while limiting steady-state dissipation to 300 mW on FR4 PCB with 35 mm² copper area at the cathode tab.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 23.52 V to 24.48 V at IZ = 5 mA - defines stable regulation point for bias networks |
| Tolerance | ±2 % - enables high-accuracy voltage referencing without post-calibration |
| Differential Resistance rdiff | 16.8 Ω max at IZ = 5 mA - limits output voltage deviation under current load changes |
| Total Power Dissipation Ptot | 300 mW at Tamb = 25 °C on FR4 with 35 mm² cathode copper - sets maximum continuous DC power handling |
| Non-repetitive Peak Power PZSM | 40 W for 100 µs square wave - supports transient overvoltage clamping without failure |
| Thermal Resistance Rth(j-a) | 350 K/W in free air - determines junction temperature rise under steady-state operation |
| Reverse Current IR | ≤ 70 µA at VR = 18.4 V - defines leakage threshold before breakdown onset |
Pinout & Package
SOD523 (SC-79) ultra-small surface-mount plastic package: 1.25 mm × 0.85 mm body, 0.65 mm height, cathode marked by bar on top surface; designed for reflow soldering with standardized footprint per Figure 10.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated voltage node; marking bar identifies this terminal - reverse-biased during regulation |
| 2 (A) | Anode | Connected to circuit ground or lower potential; completes Zener conduction path when reverse voltage exceeds VZ |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-compact SOD523 package | Enables placement in high-density layouts where board space is constrained below 1.1 mm² footprint |
| ±2 % Zener voltage tolerance | Reduces need for external trimming in precision reference designs such as ADC biasing or op-amp feedback |
| Low 16.8 Ω dynamic impedance | Maintains regulation stability across ±1 mA load current variations in sensor excitation circuits |
| 40 W surge capability | Clamps ESD transients (IEC 61000-4-2 Level 4) without degradation when placed at I/O interface inputs |
| Cathode-bar polarity marking | Eliminates assembly orientation errors during automated pick-and-place, ensuring correct reverse-bias connection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C24 | Same 24 V ±5 % tolerance, higher 500 mW Ptot, SOD523 package | Less precise regulation but higher continuous power handling | Select when >300 mW steady-state dissipation is required and ±5 % tolerance is acceptable |
| MM3Z24VT1G | Same 24 V ±2 %, SOD323 package (1.7 × 1.3 mm), 200 mW Ptot | Larger footprint, lower power rating, identical electrical specs | Select when SOD323 is preferred for legacy layout compatibility or thermal derating margin |
Compared with BZX584-C24 and MM3Z24VT1G, MM5Z24VT5GF delivers tighter ±2 % tolerance in the smallest SOD523 form factor while maintaining 300 mW dissipation - optimal for miniaturized, accuracy-critical biasing where board area and regulation precision are prioritized over raw power headroom.

FAQ
What is the maximum continuous forward current for MM5Z24VT5GF?
The MM5Z24VT5GF is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per Table 5, but forward conduction is not part of its functional use case. Forward voltage is specified at 1.1 V max for 100 mA pulse testing - not for sustained forward bias.
Can MM5Z24VT5GF be used in parallel for higher power dissipation?
No - Zener diodes exhibit manufacturing spread in breakdown voltage; paralleling MM5Z24VT5GF units causes current hogging, thermal runaway, and premature failure. For higher power, use a single higher-rated Zener or switch to an active regulator topology.
How does the cathode marking align with PCB silkscreen for SOD523 placement?
The cathode (pin 1) is indicated by a bar on the top surface of the MM5Z24VT5GF package; this matches the standard SOD523 footprint where the silkscreen 'K' or 'bar' indicator aligns with the leftmost pad in the JEDEC-standard orientation - verified in Figure 9 of the datasheet.
Is MM5Z24VT5GF suitable for automotive applications?
No - MM5Z24VT5GF is not AEC-Q200 qualified and lacks automotive-grade screening, temperature range validation (−40 °C to +125 °C), or stress testing. It is rated for −55 °C to +150 °C ambient but not validated for automotive vibration, humidity, or lifetime requirements.
