TFZVTR11B

Single Zener Diodes Overview

The TFZVTR11B is a single Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a nominal Zener voltage of 11 V with a maximum reverse leakage current of 200 nA and a Zener impedance of 10 Ohms at a test current of 10 mA. The device operates within a temperature range of -55 C to +150 C and dissipates up to 500 mW. It is housed in an SOD-323HE-2 package measuring 2.1 mm in length, 1.5 mm in width, and 0.8 mm in height. The component is AEC-Q101 qualified and available in Reel, Cut Tape, and MouseReel packaging formats.

Single Zener Diodes Procurement Notes

Verify the specific suffix and package variant against official ROHM documentation before procurement. Confirm AEC-Q101 automotive qualification requirements if applicable to your design. Ensure compatibility with SOD-323HE-2 footprint dimensions during PCB layout. Check for any obsolete status or recommended new designations in the latest manufacturer lifecycle notices.

Single Zener Diodes Selection Notes

Select this component when a 11 V regulation point is required in space-constrained environments. The SOD-323HE-2 package offers a balance between power handling and miniaturization. Consider the 10 mA test current condition for circuit biasing calculations. Verify that the 500 mW power dissipation rating aligns with the expected thermal environment of the final assembly.

Single Zener Diodes Part Context
