About Zener Diodes

Zener diodes provide controlled voltage regulation by “clamping” excess voltage in reverse-bias mode. Unlike standard diodes, they exploit the Zener breakdown effect to maintain stable reference voltages, making them indispensable for protecting sensitive components from voltage spikes.

These devices are fundamental in power supplies, voltage references, and surge protectors. Their precision tolerance and power-handling capabilities ensure system stability across medical, automotive, and industrial applications where voltage consistency is critical.

FAQs

Q: What is the reverse leakage current at 8V?
A: 2.5µA maximum at 25°C, ensuring minimal power loss during standby.

Q: Is this diode suitable for automotive applications?
A: Yes, it operates across industrial temperature ranges (-65°C to 150°C) and meets AEC-Q101 standards.

Q: What PCB footprint does the SMA package require?
A: Compatible with standard DO-214AC/SMA land patterns (datasheet available on PCXCo.com).

Q: Can I parallel multiple Zeners for higher power handling?
A: Not recommended due to current imbalance; use a single higher-wattage diode instead.

Q: How does impedance (Zzt) affect performance?
A: Lower impedance (4.5Ω max) provides sharper voltage regulation during current fluctuations.

Q: Does PCX provide datasheets?
A: Yes, download the full onsemi datasheet from our product page or contact support.
