HZS11B3LTD-E

Single Zener Diodes Overview

The HZS11B3LTD-E is a single silicon epitaxial planar Zener diode manufactured by Renesas Electronics Corporation. It features a nominal Zener voltage of 10.9 V and a power dissipation rating of 0.4 W. The device utilizes a DO-35 glass axial leaded package, designated as O-LALF-W2 in JEDEC standards. Key electrical characteristics include a maximum dynamic impedance of 25 Ω and an operating temperature range extending up to 175 °C. Designed for stabilized power supply applications, it offers low leakage current and low Zener impedance properties within the HZ series spectrum.

Single Zener Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status, as specific variants may differ. Ensure the DO-35 package dimensions match PCB footprint requirements. Validate thermal management capabilities for the intended operating environment. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Single Zener Diodes Selection Notes

Select this component when a 10.9 V reference with 0.4 W dissipation is required. Consider the DO-35 package constraints for board space. Evaluate the 25 Ω dynamic impedance against circuit sensitivity. Compare performance against other HZ series voltages if different regulation levels are needed. Assess thermal limits relative to ambient conditions.

Single Zener Diodes Part Context

This component belongs to the HZ Series of Silicon Epitaxial Planar Zener Diodes designed for stabilized power supplies. The series offers a wide voltage spectrum from 1.6 V to 38 V. The HZS11B3LTD-E specifically addresses the 10.9 V segment. It shares common packaging and material properties with other members of the HZ family, such as the HZU-L series.

Single Zener Diodes Replacement Considerations

Check for direct substitutes within the HZ series offering identical 10.9 V ratings. Verify pinout compatibility for DO-35 packages. Ensure replacement parts meet the same 0.4 W power and 175 °C temperature specifications.
