Product details
Overview
SZMM5Z10VT5GF from Nexperia is a 10 V ±2 % tolerance Zener diode in SOD523 (SC-79) package, designed for precision voltage regulation and reference functions in space-constrained PCBs. It delivers 10.0–10.2 V nominal Zener voltage at 5 mA, with 0.2 Ω differential resistance, 7.0 µA reverse current at 8.0 V, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the SZMM5Z10VT5GF datasheet, SZMM5Z10VT5GF pinout, SZMM5Z10VT5GF application, or SZMM5Z10VT5GF equivalent, this device supports low-power biasing, overvoltage clamping, and voltage reference generation where ultra-small footprint, tight voltage tolerance, and automotive-grade reliability are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable output voltage under varying load and temperature conditions. Its 0.2 Ω differential resistance ensures minimal voltage deviation across 1–10 mA operating current, while the +4.5 to +8.0 mV/K temperature coefficient enables predictable drift behavior in ambient ranges from −55 °C to +150 °C.
The device uses planar epitaxial construction with cathode-marked SOD523 packaging optimized for reflow soldering on FR4 PCBs with ≥35 mm² copper area at the cathode tab. Thermal resistance from junction to solder point is 65 K/W, supporting reliable operation at up to 300 mW total power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.80–10.20 V at IZ = 5 mA - defines precise regulation threshold for 10 V rail stabilization |
| Differential Resistance (rdiff) | 0.2 Ω - ensures <±20 mV output shift across 10 mA load change |
| Reverse Current (IR) | ≤7.0 µA at VR = 8.0 V - guarantees low leakage in standby or sensing circuits |
| Total Power Dissipation (Ptot) | 300 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - enables transient surge suppression without failure |
| Thermal Resistance (Rth(j-sp)) | 65 K/W - allows direct thermal coupling to PCB copper for effective heat transfer from cathode tab |
| Temperature Coefficient (SZ) | +4.5 to +8.0 mV/K - quantifies positive VZ drift per degree Celsius for system-level compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C10 | Same 10 V nominal, ±5 % tolerance, SOD-523 package, but higher rdiff (10 Ω) and no AEC-Q101 qualification | Limited to commercial-grade consumer products; unsuitable for automotive environments | Select when cost sensitivity outweighs automotive compliance and regulation precision |
| MMSZ5240B | 10 V nominal, ±5 % tolerance, SOD-123 package (larger), rdiff = 17 Ω, Ptot = 350 mW | Higher power handling but larger footprint and looser tolerance reduce suitability for high-density automotive PCBs | Prefer for non-automotive applications requiring marginally higher continuous power |
Compared with BZX584C10 and MMSZ5240B, SZMM5Z10VT5GF offers tighter voltage control (±2 % vs. ±5 %), lower dynamic impedance (0.2 Ω vs. ≥10 Ω), and automotive qualification-making it optimal for safety-critical, space-constrained regulation where accuracy and reliability are non-negotiable.

FAQ
What is the maximum continuous reverse current this Zener can handle?
The SZMM5Z10VT5GF is rated for 200 mA maximum forward current, but as a Zener diode, its continuous reverse (Zener) current is limited by power dissipation. At 25 °C ambient and 10 V regulation, the absolute maximum continuous Zener current is 30 mA (300 mW ÷ 10 V), assuming adequate PCB copper area for thermal management.
How does the cathode marking appear on the SOD523 package?
The cathode is marked by a visible bar on the top surface of the SOD523 package, aligned with Pin 1. This marking corresponds to the cathode symbol (K) in the simplified outline drawing and matches the "K" designation in Table 2 of the datasheet.
Can this Zener be used in parallel for higher power handling?
No-parallel connection of Zener diodes is not recommended due to mismatch in Zener voltage and dynamic resistance, which causes current hogging and thermal runaway. For higher power, use a single higher-rated device or an active shunt regulator circuit.
Is the 40 W peak power rating applicable for repetitive pulses?
No-the 40 W non-repetitive peak reverse power dissipation applies only to single square-wave pulses of 100 µs duration. Repetitive surges must be evaluated using thermal time constants and average power limits; sustained operation above 300 mW will exceed junction temperature limits.
