GDZ5V1B-E3-18

Single Zener Diodes Overview

The GDZ5V1B-E3-18 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 5.1 V with a tolerance of ±2%. The device has a maximum power dissipation of 200 mW and is housed in an SOD-323 surface-mount package. Key electrical parameters include a maximum Zener impedance (Zzt) of 80 Ohms and a reverse leakage current of 2 µA at 800 mV. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 qualification.

Single Zener Diodes Procurement Notes

Verify the specific suffix E3-18 corresponds to the RoHS-compliant, tape-and-reel packaged variant. Confirm AEC-Q101 qualification status if automotive reliability is required. Ensure the SOD-323 footprint matches the target PCB design. Cross-reference datasheet revisions to confirm parameter consistency.

Single Zener Diodes Selection Notes

Select this component when precise 5.1 V regulation is needed in space-constrained designs. The ±2% tolerance offers higher accuracy than standard ±5% Zeners. The AEC-Q101 rating makes it suitable for automotive environments where standard industrial parts may not suffice. Consider the 200 mW power limit for thermal management.

Single Zener Diodes Part Context

This part belongs to Vishay's GDZ series of single Zener diodes. It shares the 5.1 V nominal voltage with other variants like MMSZ5231B but differs in package (SOD-323 vs SOD-123), power rating (200 mW vs 500 mW), and tolerance (±2% vs ±5%). The GDZ series is specifically noted for its automotive qualification.
