Product details
Overview
MM5Z4714T1G from onsemi is a 33 V ±5% Zener voltage regulator diode in SOD−523 package, rated for 500 mW power dissipation at TL = 75°C, with 50 µA test current (IZT), 25.0 V reverse voltage (VR) at 1 µA leakage, and ESD rating >16 kV (HBM). It provides precision voltage clamping in space-constrained portable power rails.
For engineers reviewing the MM5Z4714T1G datasheet, pinout, applications, or equivalent options, key selection criteria include nominal Zener voltage tolerance, low leakage at VR, thermal derating behavior, and SOD−523 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates as a two-terminal shunt voltage reference, maintaining regulation by conducting reverse current above its specified VZ threshold. Its 33 V nominal Zener voltage falls within the 1.8–43 V family range, with temperature coefficient optimized for stability across −55°C to +150°C junction range.
The SOD−523 package enables automated placement and reflow soldering, with 260°C/10s maximum solder temperature and UL 94 V−0 flammability rating. Junction-to-ambient thermal resistance is 250°C/W, requiring careful layout consideration for sustained 500 mW operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 31.35–34.65 V @ IZT = 50 µA - defines clamping threshold with ±5% tolerance at thermal equilibrium (TL = 30°C). |
| Power Dissipation (PD) | 500 mW @ TL = 75°C - usable continuous power on FR−5 board; derates 4.0 mW/°C above 75°C. |
| Reverse Leakage (IR) | ≤1 µA @ VR = 25.0 V - ensures minimal standby current in overvoltage protection circuits. |
| Junction Temp Range | −55°C to +150°C - supports operation in automotive under-hood and industrial ambient environments. |
| ESD Rating | Class 3 (>16 kV HBM) - withstands handling and board-level electrostatic discharge without parameter shift. |
| Package | SOD−523 (1.20 × 0.80 × 0.60 mm) - surface-mount footprint compatible with 0201-class pick-and-place and reflow processes. |

Key Features
| Feature | Design Value |
|---|---|
| Low IZT test current | 50 µA enables stable regulation in ultra-low-power bias networks without loading sensitive references. |

FAQ
What is the Zener voltage tolerance of MM5Z4714T1G?
The MM5Z4714T1G has a nominal Zener voltage of 33 V with a tolerance of ±5%, meaning the actual measured VZ at IZT = 50 µA falls between 31.35 V and 34.65 V under thermal equilibrium conditions (TL = 30°C ±1°C). This tolerance is guaranteed per the Electrical Characteristics table in the official onsemi datasheet Rev. 5.
Does MM5Z4714T1G meet automotive qualification standards?
Yes, the MM5Z4714T1G is AEC−Q101 qualified and PPAP capable, confirming its suitability for automotive applications such as body control modules and infotainment power rails. The SZ-prefix variant (SZMM5Z4714T1G) is explicitly designated for automotive use, but the MM5Z4714T1G itself shares the same qualification status per onsemi documentation.
What is the maximum reverse leakage current for MM5Z4714T1G at 25 V?
The MM5Z4714T1G exhibits a maximum reverse leakage current (IR) of 1 µA when biased at VR = 25.0 V, as specified in the Electrical Characteristics table. This low leakage supports energy-efficient operation in battery-powered devices where standby current must be minimized.
Can MM5Z4714T1G be used in place of MM5Z4700T1G?
No - MM5Z4700T1G is a 13 V Zener diode (12.35–13.65 V), while MM5Z4714T1G is a 33 V device (31.35–34.65 V). They belong to the same MM5Z4xxxTxG family and share identical packaging and construction, but their Zener voltages differ by more than 20 V; direct substitution would result in incorrect clamping behavior and potential system failure.
What is the thermal resistance junction-to-ambient for MM5Z4714T1G?
The MM5Z4714T1G has a junction-to-ambient thermal resistance (RJA) of 250°C/W, measured via infrared scan method on FR−5 board. This value informs thermal design: at 500 mW dissipation, the junction temperature rise above ambient will be approximately 125°C, necessitating layout attention to copper area and airflow in sustained operation.
