Product details
Overview
MMSZ4696 RHG from Taiwan Semiconductor is a surface-mount Zener diode designed for precision voltage regulation and overvoltage protection in low-power circuits, with a nominal zener voltage of 9.1 V, 500 mW power dissipation, and SOD-123 package. It operates across -55°C to +150°C junction temperature and delivers stable clamping in power supply feedback paths, reference circuits, and ESD-sensitive signal lines.
For engineers reviewing the MMSZ4696 RHG datasheet, MMSZ4696 RHG pinout, MMSZ4696 RHG application, or MMSZ4696 RHG equivalent, key selection criteria include its 8.645–9.555 V zener voltage tolerance at 50 mA test current, 1.0 µA leakage at 6.9 V reverse bias, thermal resistance of 340°C/W, and compatibility with high-density PCB layouts requiring RoHS-compliant, halogen-free components.
Technical Context
The MMSZ4696 RHG functions as a two-terminal voltage reference device operating in reverse breakdown mode, where zener conduction maintains a stable cathode-to-anode voltage under controlled current conditions. Its performance is specified at 25°C ambient with derating above 25°C per a defined power-temperature curve.
Designed for surface-mount assembly on standard PCBs, it uses matte tin-plated leads compliant with J-STD-002 solderability and features a moisture sensitivity level (MSL) 1 rating per J-STD-020 - eliminating bake requirements prior to reflow.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C9V1 | Same 9.1 V nominal zener voltage but 300 mW rating and SOD-323 package | Lower power handling and smaller footprint limit use in higher-current regulation | Select when board space is constrained and power demand stays below 300 mW |
| MMBZ5240B | 9.1 V nominal zener in SOT-23 package with 350 mW rating and higher leakage (5 µA @ 7.3 V) | Higher leakage and different thermal profile affect precision reference stability in low-power designs | Prefer for legacy SOT-23 footprints where rework is impractical |

FAQ
What is the nominal zener voltage of the MMSZ4696 RHG?
The MMSZ4696 RHG has a nominal zener voltage of 9.1 V, with a guaranteed range of 8.645 V to 9.555 V at 50 mA test current. This specification is measured under standard conditions (TA = 25°C) and defines the device's primary regulation point in shunt reference and clamping applications. The MMSZ4696 RHG maintains this voltage with low dynamic impedance and minimal temperature drift across its operating range.
What package type does the MMSZ4696 RHG use?
The MMSZ4696 RHG is housed in an SOD-123 surface-mount package measuring 2.85 mm × 1.80 mm, with a cathode band marking polarity. Its matte tin-plated leads meet J-STD-002 solderability standards, and the molded plastic body complies with UL 94V-0 flammability requirements. The MMSZ4696 RHG's SOD-123 footprint supports high-density PCB layouts and automated assembly processes.
What is the maximum power dissipation rating for the MMSZ4696 RHG?
The MMSZ4696 RHG has a steady-state power dissipation rating of 500 mW at 25°C ambient temperature, with derating applied above that temperature per the published power-temperature curve. This rating assumes mounting on a 5 cm × 5 cm copper pad; actual usable power depends on PCB layout and airflow. The MMSZ4696 RHG's 500 mW capability exceeds many competing Zeners in the same package size.
Is the MMSZ4696 RHG RoHS and halogen-free compliant?
Yes, the MMSZ4696 RHG is fully RoHS compliant and halogen-free, meeting EU Directive 2011/65/EU and IPC-4101 requirements. These environmental qualifications are confirmed in the official Taiwan Semiconductor documentation and apply to all units shipped under ordering code MMSZ4696 RHG. The MMSZ4696 RHG is suitable for export to and use in regions enforcing strict substance restrictions.
What is the leakage current specification for the MMSZ4696 RHG?
The MMSZ4696 RHG exhibits a maximum leakage current of 1.0 µA at 6.9 V reverse bias voltage (VR), measured at 25°C ambient. This low leakage supports energy-efficient operation in battery-powered and always-on systems. The MMSZ4696 RHG's leakage remains stable across its rated junction temperature range, contributing to predictable long-term performance in precision reference designs.
