GDZ15B-HE3-18

Single Zener Diodes Overview

The GDZ15B-HE3-18 is a silicon planar Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 15 V with a tolerance of ±4% and a maximum power dissipation of 200 mW. The device is housed in an SOD-323 surface-mount package (SC-76). Key electrical parameters include a maximum Zener impedance (Zzt) of 42 Ohms and a reverse leakage current of 100 nA at 11 V. It operates within a junction temperature range of -55°C to 150°C and holds AEC-Q101 automotive qualification.

Single Zener Diodes Feature Summary

• Low Zener impedance and low leakage current characteristics
• Compact surface mount device suitable for space-constrained designs
• Automotive grade reliability with AEC-Q101 qualification

Single Zener Diodes Applications

• Voltage reference circuits in automotive electronics
• Protection against overvoltage transients
• Clamping applications in compact consumer devices

Single Zener Diodes Procurement Notes

Verify the specific suffix HE3-18 to confirm RoHS compliance and tape-and-reel packaging configuration. Ensure compatibility with SOD-323 footprint requirements during PCB layout. Confirm that the ±4% voltage tolerance meets the precision needs of the target application, as tighter tolerances may require alternative part numbers within the GDZ series.

Single Zener Diodes Selection Notes

Select this component when a 15 V regulation point is required in a small form factor. The 200 mW power rating limits its use in high-current scenarios; ensure thermal management supports this dissipation level. The AEC-Q101 certification makes it suitable for automotive environments where standard commercial parts may not suffice. Compare Zzt values if dynamic impedance performance is critical for the specific circuit design.

Single Zener Diodes Part Context

This part belongs to the GDZ-G series of small signal Zener diodes from Vishay. The series is noted for popularity in Asian designs due to its compact size and reliable performance. The GDZ15B variant specifically targets applications requiring stable voltage references in portable and automotive equipment where board space is limited.

Single Zener Diodes Replacement Considerations

GDZ15B-E3-18 and GDZ15B-G3-18 are parameter-equivalent alternatives within the same manufacturer's portfolio. Verify pinout and package dimensions remain identical before substitution.
