DESCRIPTION
This new multi-layer pn junction Zener design for ultra-sharp knee characteristics is used for
low-voltage regulation and very low leakage currents. The new design offers significantly
improved voltage regulation and lower dynamic impedance and capacitance compared to
conventional Zeners. They also provide ESD protection for those threats defined per IEC
61000-4-2 or electrical fast transients per IEC 61000-4-4 as well as other transient threats.
Because of their relatively small physical size and weight, this product is ideal for use in High
reliable portable and hand-held electronic devices.

FEATURES
• Ultra-sharp knee, low-voltage Zener
• Excellent Voltage Regulation (4X better than standard Zener diode)
• Lower Zener impedance (1/4 that of standard Zener diode)
• Lower leakage current (about 40X lower than standard Zener diode)
• Lower capacitance
• Small, hermetically sealed, surface mount UB package
• High surge capability
• RoHS compliant versions are available
• ESD Nonsensitive Rating

APPLICATIONS / BENEFITS
• Superior low voltage regulation
• Portables requiring low battery drain
• ESD & EFT protection per IEC 61000-4-2 and IEC 61000-4-4
• Stabistor replacement
• Low voltage transient protection
