CMOZ16V TR PBFREE

Single Zener Diodes Overview

The Central Semiconductor CMOZ16V TR PBFREE is a surface-mount silicon Zener diode in the ULTRAmini™ SOD-523 package. It provides a nominal Zener voltage of 16 V with a 5% tolerance (15.20 V min, 16.80 V max). The device operates at a test current of 5.0 mA, featuring a maximum Zener impedance of 40 Ω and a reverse leakage current of 0.05 μA at 11.2 V. It dissipates up to 350 mW on ceramic cores or 300 mW on FR-4 boards, with an operating junction temperature range of -65°C to +150°C.

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' indicates tape-and-reel packaging and 'PBFREE' confirms lead-free composition. Confirm the specific manufacturer datasheet version matches the required electrical tolerances and thermal characteristics before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 16 V Zener voltage is required in a small SOD-523 footprint. Ensure the application supports the specified 5.0 mA test current and verify that the board layout accommodates the necessary copper pad area to achieve the rated power dissipation limits.

Single Zener Diodes Part Context

This part belongs to the CMOZ2V4 Series, which covers Zener voltages from 2.4 V to 43 V. All series members share the same SOD-523 mechanical outline and general thermal ratings, differing primarily in their specific voltage breakdown points and associated marking codes.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering 16 V Zener diodes in the SOD-523 package. Verify that substitute parts match the 40 Ω impedance and 0.05 μA leakage specifications to ensure functional equivalence.

Single Zener Diodes FAQ

What is the maximum forward voltage drop?

The maximum forward voltage is 0.9 V at a forward current of 10 mA.

How does the mounting pad area affect power dissipation?

Power dissipation decreases from 350 mW on ceramic/aluminum cores to 250 mW on FR-4 boards with smaller 1.4 mm² copper pads.
