Product details
Overview
MMSZ4710-E3-18 from Vishay Semiconductors is a silicon planar Zener diode rated for 25 V nominal Zener voltage (23.8–26.3 V range), ±5 % tolerance, 500 mW maximum power dissipation on lead, and 0.05 mA test current; it operates from –55 °C to +150 °C and is used for precision voltage regulation in low-power analog reference circuits.
For engineers reviewing the MMSZ4710-E3-18 datasheet, MMSZ4710-E3-18 pinout, MMSZ4710-E3-18 application, or MMSZ4710-E3-18 equivalent, this page delivers verified Zener voltage range, thermal resistance values, SOD-123 package dimensions, reverse leakage at VR, and AEC-Q101 qualification status where applicable.
Technical Context
This device functions as a single-element, cathode-marked Zener diode with fixed breakdown voltage defined under thermal equilibrium conditions at IZT = 0.05 mA. Its junction-to-ambient thermal resistance is 420 K/W on FR-4 board per JEDEC 51-3, and maximum junction temperature is limited to 150 °C.
The SOD-123 surface-mount package features UL 94 V-0 molding compound, MSL level 1 moisture sensitivity, and supports peak reflow up to 260 °C. Reverse current is specified at 0.01 μA when VR = 19 V, confirming tight leakage control for stable reference use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 23.8–26.3 V at IZT = 0.05 mA - defines regulated output range for low-current bias/reference applications |
| Power Dissipation (Ptot) | 500 mW (junction-to-lead), 300 mW (on FR-4 board) - sets maximum continuous power handling in PCB layout |
| Thermal Resistance | RthJA = 420 K/W, RthJL = 250 K/W - determines junction temperature rise under load and heatsinking requirements |
| Reverse Leakage (IR) | ≤ 0.01 μA at VR = 19 V - ensures minimal error current in high-impedance reference paths |
| Operating Temperature | –55 °C to +150 °C - supports industrial and automotive ambient environments without derating |
| Zener Tolerance | ±5 % - enables predictable voltage setting without post-calibration in cost-sensitive designs |
Pinout & Package

| Cathode | Zener breakdown terminal / regulated output node | Marked by bar; supplies stable voltage referenced to anode when reverse biased above VZ |
Key Features
| Feature | Design Value |
|---|---|
| Silicon planar construction | Ensures consistent Zener voltage distribution and long-term stability across temperature cycles |
| ±5 % VZ tolerance | Reduces need for external trimming in voltage reference and feedback divider networks |
| ESD robustness | HBM > 8 kV, MM > 800 V - protects against assembly and handling electrostatic discharge events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C24-TR | 24 V nominal, ±5 %, 500 mW, DO-35 package, higher IR (≤5 μA at 19 V) | Larger DO-35 through-hole footprint; less suitable for dense SMT layouts | Select when legacy through-hole assembly or higher leakage tolerance is acceptable |
| MMBZ5242B-7-F | 24 V nominal, ±5 %, 350 mW, SOT-23 package, IR ≤ 0.1 μA at 18 V | Lower power rating and different thermal profile; requires layout adjustment for thermal relief | Choose for space-constrained boards where SOT-23 fits but SOD-123 does not |

FAQ
What is the exact Zener voltage range for MMSZ4710-E3-18?
The MMSZ4710-E3-18 has a guaranteed Zener voltage range of 23.8 V to 26.3 V at test current IZT = 0.05 mA and Tamb = 25 °C, with nominal value 25 V and ±5 % tolerance. This range is measured under thermal equilibrium conditions as defined in the Vishay datasheet document 86343 Rev. 1.1.
Is MMSZ4710-E3-18 AEC-Q101 qualified?
No, MMSZ4710-E3-18 is the commercial-grade variant. The AEC-Q101 qualified version is MMSZ4710-HE3_A-18. Both share identical electrical specifications and SOD-123 packaging, but only the HE3_A suffix indicates automotive qualification per AEC-Q101 stress testing requirements.
What is the maximum reverse leakage current for MMSZ4710-E3-18?
The maximum reverse leakage current for MMSZ4710-E3-18 is 0.01 μA at VR = 19 V and Tamb = 25 °C. This value is confirmed in the Electrical Characteristics table of the Vishay datasheet and reflects tight leakage control critical for high-impedance reference applications.
Can MMSZ4710-E3-18 be used in reflow soldering processes?
Yes, MMSZ4710-E3-18 supports standard lead-free reflow soldering with peak temperature up to 260 °C, per its SOD-123 package specification. It is rated MSL level 1 (unlimited floor life) and complies with JEDEC J-STD-020 guidelines for moisture sensitivity.
What is the thermal resistance junction-to-ambient for MMSZ4710-E3-18 on FR-4 board?
The thermal resistance junction-to-ambient (RthJA) for MMSZ4710-E3-18 is 420 K/W when mounted on an FR-4 board with the recommended soldering footprint per JEDEC 51-3. This value is essential for calculating junction temperature rise under actual operating power dissipation.
