Product details
Overview
SZMM5Z4697T1G from onsemi is a 10 V ±5% Zener voltage regulator diode in SOD−523 package, rated for 500 mW power dissipation at 75°C, with 50 μA test current (IZT), 1 μA leakage current at 7.6 V reverse bias, and AEC−Q101 qualification for automotive use in space-constrained voltage reference and overvoltage protection circuits.
For engineers reviewing the SZMM5Z4697T1G datasheet, pinout, applications, or equivalent options, key selection criteria include nominal Zener voltage tolerance, thermal derating behavior, ESD robustness (>16 kV HBM), low-leakage performance at VR = 7.6 V, and automotive-grade reliability validation.
Technical Context
This device operates as a two-terminal silicon Zener diode with sharp reverse breakdown at 10 V nominal, designed for stable voltage clamping and reference generation in low-power analog and mixed-signal subsystems. Its SOD−523 footprint enables high-density placement while maintaining thermal performance up to 150°C junction temperature.
The SZ prefix denotes automotive-qualified production with PPAP capability, distinct from commercial MM5Z variants. It exhibits a positive temperature coefficient near 10 V (≈+5.5 mV/°C), confirmed by typical TC curves in the datasheet, and supports steady-state operation under 4.0 mW/°C derating above 75°C ambient.
Key Specifications

FAQ
What is the Zener voltage tolerance of SZMM5Z4697T1G?
The SZMM5Z4697T1G has a Zener voltage range of 9.50 V to 10.50 V at IZT = 50 μA, corresponding to a ±5% tolerance around the nominal 10 V value. This tolerance is guaranteed across the full operating temperature range of −55°C to +150°C and is validated per AEC−Q101 test conditions. The SZMM5Z4697T1G datasheet specifies this range in the Electrical Characteristics table on page 3.
Is SZMM5Z4697T1G suitable for automotive applications?
Yes, SZMM5Z4697T1G is explicitly qualified to AEC−Q101 standards and designated with the "SZ" prefix to indicate automotive-grade manufacturing controls, PPAP capability, and site-specific change management. It undergoes rigorous stress testing including high-temperature operating life, temperature cycling, and human-body-model ESD (>16 kV), making SZMM5Z4697T1G appropriate for under-hood and body-control module deployments.
What is the maximum power dissipation for SZMM5Z4697T1G on an FR−5 board?
SZMM5Z4697T1G is rated for 500 mW total power dissipation on an FR−5 board at a lead temperature (TL) of 75°C. Above 75°C, power must be linearly derated at 4.0 mW/°C, reaching zero dissipation at 200°C TL. This rating assumes the minimum recommended footprint per the datasheet and accounts for thermal resistance of 250°C/W (Junction-to-Ambient).
Does SZMM5Z4697T1G have a specified temperature coefficient?
Yes, SZMM5Z4697T1G exhibits a positive temperature coefficient near its 10 V operating point, approximately +5.5 mV/°C, as shown in Figure 1 of the datasheet. This value is derived from typical TC curves for nominal Zener voltages between 9 V and 11 V and supports predictable voltage drift modeling across −55°C to +150°C operating conditions for SZMM5Z4697T1G.
What is the leakage current specification for SZMM5Z4697T1G?
SZMM5Z4697T1G has a maximum reverse leakage current (IR) of 1 μA when biased at VR = 7.6 V, measured at TA = 25°C. This low-leakage performance is critical for battery-powered applications where standby current must be minimized. The value is specified in the Electrical Characteristics table on page 3 and confirmed by Figure 6 (Typical Leakage Current) in the datasheet.
