HZM22NB2TL-E

Single Zener Diodes Overview

The HZM22NB2TL-E is a single Zener diode manufactured by Renesas, designed for surface-mount applications. It features a nominal Zener voltage of 22.01 V with a tight tolerance of ±2.11%. The device is rated for a maximum power dissipation of 200 mW and operates within a junction temperature range up to 150°C. Key electrical characteristics include a maximum impedance of 55 Ohms and a reverse leakage current of 2 µA at 17 V. The component is housed in a compact 3-MPAK package, which corresponds to the TO-236-3, SC-59, or SOT-23-3 form factors.

Single Zener Diodes Procurement Notes

Verify RoHS compliance status as the part is listed as non-compliant in available documentation. Confirm end-of-life status with the manufacturer or authorized distributors before finalizing design-in decisions. Ensure the 3-MPAK footprint matches the target PCB layout constraints. Validate that the 200 mW power rating meets the thermal requirements of the specific application environment.

Single Zener Diodes Selection Notes

Select this component when a precise 22.01 V Zener reference is needed in a small surface-mount package. Consider the ±2.11% tolerance for applications requiring tighter voltage accuracy than standard Zener diodes offer. Evaluate the 200 mW power rating against expected operating conditions to ensure adequate thermal headroom. The 3-MPAK package offers a balance between performance and board space efficiency.
