Product details
Overview
SZMM5Z13VT5GF from Nexperia is a 13 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 12.74–13.26 V nominal Zener voltage at IZ = 8 mA, 0.1 Ω typical differential resistance, and AEC-Q101 qualification for automotive voltage regulation.
For engineers reviewing the SZMM5Z13VT5GF datasheet, SZMM5Z13VT5GF pinout, SZMM5Z13VT5GF application, or SZMM5Z13VT5GF equivalent, this device supports precision low-power voltage reference, overvoltage clamping, and biasing in space-constrained automotive ECUs, sensor signal conditioning circuits, and industrial power supply feedback loops.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its 12.74–13.26 V Zener voltage range at 8 mA test current, ±2 % tolerance, and 7.0 mV/K temperature coefficient ensure predictable regulation behavior in ambient temperatures from −55 °C to +150 °C.
Designed for surface-mount use in ultra-compact layouts, it features low thermal resistance (65 K/W junction-to-solder-point), 105 pF capacitance at 0 V, and 170 µA maximum reverse leakage at 10.4 V, enabling reliable performance in high-frequency noise suppression and transient voltage suppression roles.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C13 | Same 13 V nominal, ±5 % tolerance, SOD523 package, but only 200 mW Ptot and no AEC-Q101 qualification | Limited to commercial-grade consumer power supplies; not suitable for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification and tighter tolerance requirements |
| MMSZ5242B | 13 V nominal, ±5 % tolerance, SOD-123 package (larger), 500 mW Ptot, no AEC-Q101 | Higher power handling but 2.5× larger footprint; requires PCB redesign for space-constrained layouts | Choose where higher continuous power is needed and board area permits larger SOD-123 placement |
Compared with BZX584-C13 and MMSZ5242B, SZMM5Z13VT5GF delivers tighter ±2 % tolerance, AEC-Q101 compliance, and optimized thermal resistance for automotive and high-reliability industrial use - all within the smallest SOD523 footprint.

FAQ
What is the maximum continuous forward current for SZMM5Z13VT5GF?
The device is rated for 200 mA maximum forward current per absolute maximum ratings. However, it is designed for reverse-bias Zener operation; forward conduction is limited to brief pulses (≤300 µs) with ≤1.1 V drop at 100 mA, and sustained forward bias exceeds safe operating area limits.
Can SZMM5Z13VT5GF be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated device or active regulation instead of parallel Zeners.
How does the 7.0 mV/K temperature coefficient affect regulation accuracy?
At 13 V nominal, a 7.0 mV/K coefficient means output voltage shifts +0.91 V over a 130 K rise (e.g., −20 °C to +110 °C). This is factored into system-level calibration; the ±2 % initial tolerance dominates error budget below 85 °C ambient.
Is the SOD523 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D reflow profiles. The recommended footprint (Fig. 10) uses 0.5 mm pad width, 1.4 mm pad length, and 0.4 mm solder mask opening to ensure reliable wetting and mechanical strength without tombstoning.
