BZD27B5V6P-E3-18

Single Zener Diodes Overview

The BZD27B5V6P-E3-18 is a silicon planar Zener diode from Vishay, housed in the SMF (DO-219AB) surface-mount package. It features a nominal Zener voltage of 5.6 V with a tolerance range of 5.49 V to 5.71 V at a test current of 100 mA. The device supports a maximum power dissipation of 800 mW at 30 °C and up to 2300 mW at 105 °C case temperature. It exhibits low leakage current (10 µA max at 3 V), dynamic resistance of 2 Ω typical and 4 Ω maximum, and operates within a junction temperature range of -65 °C to +175 °C.

Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required tape configuration. The suffix indicates packaging on a 13-inch reel with a minimum order quantity of 50,000 units. Confirm compliance requirements against the base part number designation to ensure alignment with project specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 5.6 V reference is needed in a compact footprint. The low dynamic resistance ensures effective regulation under varying load conditions. Ensure thermal management accounts for the specified power derating curves above 30 °C ambient temperature.

Single Zener Diodes Part Context

This device belongs to the BZD27B series, which offers 43 breakdown voltages ranging from 3.6 V to 200 V. The series provides consistent electrical characteristics across the voltage spectrum while maintaining the physical dimensions of the SMF package for automated assembly compatibility.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay BZD27B series variants with identical voltage ratings. Cross-brand replacements must match the DO-219AB outline and verify equivalent surge power handling capabilities.
