MMFZ47T1G

Single Zener Diodes Overview

The onsemi MMFZ47T1G is a single-channel Zener diode voltage regulator designed for surface-mount applications. It features a nominal Zener voltage of 47 V with a tolerance of ±5%. The device is housed in an SOD-123 package, measuring 3.86 mm in length and 1.35 mm in height. It supports a maximum power dissipation of 500 mW and operates within a temperature range of -55°C to +150°C. Key electrical parameters include a test current of 5 mA, a maximum reverse leakage current of 3 μA, and a maximum Zener impedance of 80 Ω.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer part number against official onsemi documentation to ensure authenticity. Confirm that the SOD-123 package dimensions and pin configuration match your PCB footprint requirements. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 47 V regulation point is required in a low-power surface-mount environment. Ensure the circuit design accounts for the 500 mW thermal limit and the specific impedance characteristics at the operating current. Verify compatibility with the intended operating temperature range and leakage current constraints.

Single Zener Diodes Part Context

This component belongs to the MMSZ/MMFZ series of small-signal Zener diodes manufactured by onsemi. These devices are part of a broader portfolio of discrete semiconductors focused on voltage regulation and protection. The SOD-123 package is a standard form factor widely used in consumer electronics and industrial control boards for its balance of performance and size.
