Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required tape configuration, as the series offers variations such as 1500 units per 7-inch reel or 6000 units per 13-inch reel. Confirm whether the commercial grade suffix or the HE3 automotive suffix is necessary for the intended application environment. Ensure the selected packaging aligns with automated assembly equipment specifications.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode with a 39 V breakdown voltage is required in an SMA package. Consider the 1.25 W power dissipation limit and the 50 Ohm dynamic resistance for regulation accuracy. Verify that the operating junction temperature range up to 150 °C meets the thermal design constraints of the target circuit board layout.

Single Zener Diodes Part Context

This part belongs to the BZG05C-Series of Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series provides a wide voltage range from 3.3 V to 100 V in the compact DO-214AC package. These devices are designed for high reliability and are suitable for general-purpose electronic applications requiring stable voltage reference or clamping.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZG05C39-E3-TR3 and BZG05C39-HE3-TR3. Cross-series replacements may require verification of package dimensions and electrical parameters against the original design requirements.
