ZMY47-GS18

Single Zener Diodes Overview

The ZMY47-GS18 is a single zener diode manufactured by Vishay Semiconductors, designed for surface-mount applications in the DO-213AB (MELF) package. It features a nominal zener voltage of 47 V with a tolerance of ±5% and a maximum power dissipation of 1 W. The device operates within a temperature range of -55°C to +175°C and exhibits a zener impedance of 60 Ohms at a test current of 10 mA. It complies with RoHS standards and is supplied in reel, cut tape, or MouseReel formats.

Single Zener Diodes Feature Summary

• High thermal stability enabling operation up to 175°C
• Glass-passivated chip construction for environmental protection
• Mechanical stress resistant design suitable for automated assembly

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels

• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix GS18 against the manufacturer's latest datasheet to confirm package dimensions and marking codes. Ensure compatibility with reflow soldering profiles specified for MELF packages. Cross-reference the Vishay part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 1 W surface-mount zener diode with high-temperature capability is required. The DO-213AB package offers compact footprint advantages over axial leads. Consider the 60 Ohm impedance for dynamic regulation needs and verify that the 47 V breakdown voltage aligns with the target circuit's operational limits and safety margins.

Single Zener Diodes Part Context

This part belongs to the ZMY series of glass-passivated junction zener diodes from Vishay. These components are engineered for general-purpose voltage regulation and protection tasks. The series provides reliable performance across industrial temperature ranges, utilizing robust MELF packaging to withstand mechanical shock and thermal cycling during PCB assembly and end-use environments.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay ZMY47 variants with different suffixes indicating minor packaging or testing differences. Equivalent parts from other manufacturers must match the 47 V zener voltage, 1 W power rating, and DO-213AB footprint to ensure mechanical and electrical compatibility without redesigning the circuit board.
