• Tight voltage tolerance of ±2% available
• RoHS compliant commercial grade option
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Radiation-hardened applications
• Low capacitance circuit requirements

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required RoHS compliance status, as this attribute applies only to commercial grade devices. Confirm the tolerance designation corresponds to the desired ±2% specification. Ensure the tape and reel packaging aligns with automated assembly needs. Cross-reference the manufacturer's latest datasheet for any updates on screening options or availability constraints.

Single Zener Diodes Selection Notes

Select this component when a surface mount equivalent to the JEDEC registered 1N4678 series is required. The 1N4698 variant specifically targets an 11 V regulation point. Consider the low capacitance characteristics if signal integrity is critical. Verify thermal resistance parameters against the PCB footprint design to ensure adequate heat dissipation within the specified junction temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 watt Zener diodes. The series offers a voltage selection range from 1.8 to 43 volts. Standard tolerances are ±5%, with tighter options available. The package serves as a surface mount alternative to the traditional axial DO-35 leaded configuration.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4698 variants such as 1N4698UR-1 or 1N4698-1. Verify that substitute parts match the DO-213AA package dimensions and electrical characteristics. Check for compatibility regarding RoHS compliance and tolerance levels before implementation.
