MMBZ5230BTW_R1_00001

Overview

The MMBZ5230BTW_R1_00001 is a surface mount silicon Zener diode from the Panjit MMBZ5221BTW series. It features a nominal Zener voltage of 4.7V with a tolerance range of 4.47V to 4.94V at an test current (IZT) of 20.0mA. The device has a maximum power dissipation of 200mW and operates within a junction temperature range of -55°C to +150°C. It utilizes a plastic SOT-363 case and is packaged on a 7-inch reel containing 3,000 pieces. The marking code for this specific voltage variant is D5.

Feature Summary

• Planar die construction designed for automated assembly processes
• Lead-free composition compliant with EU RoHS 2.0 directives
• Green molding compound meeting IEC 61249 standards

Applications

• Voltage regulation in electronic circuits
• Clipping and clamping applications
• Reference voltage sources

Procurement Notes

Verify the ordering suffix matches the required packaging quantity and tape-and-reel specifications. Confirm that the component lot number aligns with the manufacturer's tracking requirements for quality assurance purposes. Ensure compliance with the stated environmental directives before final integration.

Selection Notes

Select this component when a 4.7V reference is required in a compact SOT-363 footprint. Consider the 200mW power dissipation limit and the specific impedance characteristics at 20mA. Verify thermal derating requirements if the operating environment exceeds standard ambient temperatures.

Part Context

This part belongs to the MMBZ5221BTW ~ MMBZ5267BTW series, which covers Zener voltages from 2.4V to 75V. All members share identical mechanical dimensions and electrical ratings, differing only in their nominal breakdown voltage and corresponding marking codes.

Replacement Considerations

Direct substitutes within the same series include MMBZ5229BTW (4.3V) or MMBZ5231BTW (5.1V) if voltage adjustments are permissible. Cross-brand replacements must match the SOT-363 package, 200mW rating, and 4.7V nominal voltage.
