Product details
Overview
MMSZ4698-E3-08 from Vishay Semiconductors is a silicon planar Zener diode rated for 11 V nominal Zener voltage (10.5–11.6 V range) at 0.05 mA test current, with ±5 % tolerance, 500 mW maximum power dissipation on lead, and SOD-123 surface-mount package. It provides precision voltage regulation in low-power biasing, reference, and overvoltage protection circuits for automotive and industrial control modules.
For engineers reviewing the MMSZ4698-E3-08 datasheet, MMSZ4698-E3-08 pinout, MMSZ4698-E3-08 application, or MMSZ4698-E3-08 equivalent, this page delivers verified Zener voltage, thermal resistance, reverse leakage, RoHS-compliant packaging, and AEC-Q101-qualified alternatives - all critical for stable voltage reference design and BOM validation.
Technical Context
The MMSZ4698-E3-08 operates as a single-element, cathode-marked Zener diode optimized for thermal equilibrium voltage regulation. Its 0.05 mA test current ensures stable VZ measurement under low-power conditions, and its 8.4 µA reverse leakage at 8.4 V supports low-quiescent-current designs.
Designed for surface-mount assembly on FR-4 PCBs, it exhibits RthJA = 420 K/W and RthJL = 250 K/W, enabling reliable operation up to +150 °C junction temperature. The SOD-123 package complies with JEDEC® 51-3 thermal testing standards and UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.5–11.6 V at IZT = 0.05 mA - defines tight regulation window for 11 V reference applications |
| Power Dissipation (Ptot) | 500 mW (junction-to-lead), 300 mW (on FR-4 board) - sets max continuous bias power without heatsinking |
| Reverse Leakage (IR) | 0.05 µA at VR = 8.4 V - ensures minimal error current in high-impedance reference dividers |
| Thermal Resistance | RthJA = 420 K/W, RthJL = 250 K/W - determines allowable ambient rise before Tj exceeds 150 °C |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C11 (ON Semiconductor) | Same 11 V nominal VZ, but ±5 % tolerance at IZ = 5 mA; higher test current increases dynamic impedance | Higher power dissipation (500 mW same), but larger DO-35 package limits high-density layouts | Select when legacy through-hole compatibility or higher surge current capability is required |
| MMSZ5240B (Diodes Inc.) | 10 V nominal VZ (9.5–10.5 V), ±5 % at IZ = 20 mA; different thermal resistance (RthJA = 350 K/W) | Lower voltage grade; not interchangeable without circuit recalibration | Choose only if system tolerances allow 10 V reference and higher test current improves regulation stability |
Compared with BZX55C11 and MMSZ5240B, the MMSZ4698-E3-08 offers tighter thermal resistance control in SOD-123, lower leakage at reduced test current, and direct AEC-Q101 qualification path - making it optimal for space-constrained, automotive-grade 11 V reference designs where low quiescent current and surface-mount reliability are critical.

FAQ
What is the Zener voltage tolerance and test condition for MMSZ4698-E3-08?
The MMSZ4698-E3-08 has a Zener voltage tolerance of ±5 %, specified at a test current IZT of 0.05 mA under thermal equilibrium conditions. Its nominal VZ is 11 V, with a guaranteed range of 10.5 V to 11.6 V. This low-test-current specification ensures accurate characterization for low-power reference applications where bias current must be minimized. The MMSZ4698-E3-08 datasheet confirms this value in Table "ELECTRICAL CHARACTERISTICS" on page 2.
Is MMSZ4698-E3-08 AEC-Q101 qualified?
The MMSZ4698-E3-08 itself is the commercial-grade RoHS-compliant variant (E3 suffix). However, the AEC-Q101 qualified version is designated MMSZ4698-HE3_A-08 - identical electrically and physically but subjected to stress testing per AEC-Q101. Both share the same SOD-123 package and electrical specs. For automotive applications requiring qualification, MMSZ4698-HE3_A-08 must be specified; the MMSZ4698-E3-08 is intended for industrial and consumer use.
What is the maximum reverse leakage current for MMSZ4698-E3-08?
The MMSZ4698-E3-08 exhibits a maximum reverse leakage current (IR) of 0.05 µA at VR = 8.4 V, as specified in the "ELECTRICAL CHARACTERISTICS" table. This ultra-low leakage supports high-impedance reference networks and minimizes error in precision voltage divider configurations. The value is measured at Tamb = 25 °C and reflects the device's suitability for battery-powered or low-quiescent-current systems where standby loss must be tightly controlled.
Which package does MMSZ4698-E3-08 use, and what are its key mechanical features?
The MMSZ4698-E3-08 uses the SOD-123 surface-mount package: 2.7 mm × 1.55 mm × 1.175 mm body with cathode indicated by a bar marking. It weighs 10.6 mg, uses UL 94 V-0 compliant molding compound, and is rated MSL level 1 per J-STD-020. The recommended solder footprint and thermal pad layout are defined in the Vishay document S8-V-3910.01-003. This compact, robust package enables high-density PCB assembly while maintaining thermal performance.
Can MMSZ4698-E3-08 replace MMSZ4697 or MMSZ4699 in an existing design?
No - MMSZ4698-E3-08 is not a drop-in replacement for MMSZ4697 (10 V nominal) or MMSZ4699 (12 V nominal), as their Zener voltages differ by ≥1 V. Substituting would shift reference or clamp levels outside design margins. Each part in the MMSZ4681–MMSZ4717 family is uniquely binned; the MMSZ4698-E3-08 must be used where 11 V regulation is explicitly required. Cross-referencing should always verify VZ range, test current, and thermal specs before substitution.
