Product details
Overview
MM5Z5V6ST5G from onsemi is a 5.6 V, ±3.5% tolerance Zener diode in SOD-523 package, rated for 500 mW steady-state power dissipation, 200 Ω max Zener impedance at 5 mA test current, and 16 kV ESD (HBM). It provides precision voltage regulation in space-constrained portable electronics such as smartphone power rails and USB interface protection.
For engineers reviewing the MM5Z5V6ST5G datasheet, MM5Z5V6ST5G pinout, MM5V6ST5G application, or MM5Z5V6ST5G equivalent, key selection criteria include its tight 5.49–5.73 V Zener range, low 200 Ω dynamic impedance, −2.0 mV/°C temperature coefficient, SOD-523 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to clamp or regulate voltage with minimal deviation across temperature and current variations. Its design centers on stable reference generation under low-current conditions (IZT = 5 mA), with specified thermal coefficient (−2.0 mV/°C) and low leakage (IR ≤ 1.0 µA at VR = 4.5 V).
The device uses a silicon planar junction structure in a void-free thermosetting plastic package (CASE 502), qualified to MSL 1 and rated for 260 °C peak reflow. It meets Class 3 HBM ESD (>16 kV) and is Pb-free/RoHS compliant.

FAQ
What is the Zener voltage range of MM5Z5V6ST5G at 5 mA test current?
The MM5Z5V6ST5G has a guaranteed Zener voltage range of 5.49 V to 5.73 V when tested at IZT = 5 mA, per the onsemi datasheet Rev. 15. This 5.6 V nominal rating with ±3.5% tolerance ensures consistent clamping behavior across manufacturing lots and operating temperatures, making MM5Z5V6ST5G suitable for precision voltage reference and overvoltage protection tasks.
Is MM5Z5V6ST5G compatible with lead-free reflow processes?
Yes, MM5Z5V6ST5G is fully compatible with lead-free reflow soldering, qualified up to 260 °C peak temperature and meeting MSL 1 moisture sensitivity requirements. Its 100% matte tin lead finish and thermosetting plastic package ensure reliable wetting and mechanical integrity during standard JEDEC-compliant reflow profiles-critical for high-yield assembly of MM5Z5V6ST5G in automated SMT lines.
Does MM5Z5V6ST5G meet automotive qualification standards?
Yes, MM5Z5V6ST5G is AEC-Q101 qualified and PPAP capable, confirming its suitability for automotive applications such as infotainment power supervision and cabin sensor biasing. The device operates across −65 °C to +150 °C junction temperature and maintains specified Zener voltage, impedance, and leakage parameters under automotive stress conditions-validating MM5Z5V6ST5G for under-hood and interior module use.
What is the maximum Zener impedance of MM5Z5V6ST5G and at what condition is it specified?
The maximum Zener impedance (ZZT) of MM5Z5V6ST5G is 200 Ω, measured at the specified test current IZT = 5 mA. This low dynamic impedance ensures minimal voltage variation under changing load conditions, directly supporting MM5Z5V6ST5G's role in stabilizing reference voltages and suppressing noise in sensitive analog circuits.
How does the temperature coefficient of MM5Z5V6ST5G affect its performance across operating temperature?
MM5Z5V6ST5G has a temperature coefficient of −2.0 mV/°C at IZT = 5 mA, meaning its Zener voltage decreases by approximately 2 mV per degree Celsius rise in junction temperature. This predictable drift allows designers to compensate in system-level calibration, and combined with its −65 °C to +150 °C operating range, ensures MM5Z5V6ST5G remains within specification across industrial and automotive thermal environments.
