1N4682-TP

Overview

The MMSZ4689-TP is a single Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 5.1 V with a standard tolerance of ±5%. The device is rated for a maximum steady-state power dissipation of 500 mW and utilizes a SOD-123 surface-mount package. Electrical characteristics include a reverse leakage current of 10 µA at 3 V and a forward voltage of 950 mV at 10 mA. The component supports a junction temperature range from -55°C to 150°C.

Feature Summary

• Double slug type construction with hermetically sealed glass encapsulation
• Very sharp reverse characteristic for precise voltage regulation
• Lead-free finish compliant with RoHS3 standards

Applications

• Voltage regulation in electronic circuits
• Voltage reference applications
• Overvoltage protection circuits

Procurement Notes

Verify the authenticity of the MMSZ4689-TP component by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit parts are prevalent; unauthorized sources do not provide warranty coverage or traceability. Confirm that the ordering suffix matches the required packaging format, such as tape and reel or bulk, before finalizing procurement.

Selection Notes

Select this component for designs requiring a 5.1 V reference with a 500 mW power rating in a compact SOD-123 footprint. Ensure the operating environment remains within the specified -55°C to 150°C junction temperature range. Verify that the circuit current requirements align with the maximum Zener current specifications provided in the datasheet.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500 mW silicon Zener diodes produced by MCC. The series covers a wide voltage range from 1.8 V to 43 V. The MMSZ4689-TP specifically corresponds to the 5.1 V variant within this family, offering standard tolerance options for general-purpose regulation tasks.

Replacement Considerations

Direct substitutes include other manufacturers' equivalents meeting the 5.1 V Zener voltage, 500 mW power rating, and SOD-123 package outline. Verify pinout compatibility and thermal resistance parameters when cross-referencing with alternative suppliers.
