4692

Overview

The Visaton 4692 is a silicon unidirectional voltage regulator diode chip manufactured by CDI-Diode. It provides a nominal regulation voltage of 6.8 V with a power capability of 0.5 W when properly heat-sunk. The device features low operating current at 50 µA and is electrically equivalent to the 1N4678 through 1N4717 series. It supports wire bonding and die attach techniques, excluding solder reflow. Operating temperatures range from -65°C to +175°C, with storage limits matching operational bounds.

Feature Summary

• Unidirectional voltage regulation using silicon technology
• Complete junction protection via silicon dioxide
• Compatibility with standard wire bonding and die attach processes

Applications

• Voltage reference circuits in integrated modules
• Overvoltage protection for sensitive semiconductor junctions
• Biasing networks requiring stable low-current regulation

Procurement Notes

Verify that the specific lot corresponds to the CDI-Diode manufacturing origin rather than generic Visaton branding. Confirm RoHS compliance status directly with the supplier documentation. Ensure thermal management design accounts for the 0.5 W limit without active cooling. Validate that the application environment remains within the specified -65°C to +175°C operational range to maintain reliability.

Selection Notes

Select this component when a compact, low-power zener solution is required for space-constrained designs. It serves as a direct replacement for standard 1N46xx series diodes in chip form. Consider its compatibility with surface-mount assembly processes that avoid solder reflow. Evaluate thermal dissipation requirements carefully due to the limited 0.5 W power rating under normal conditions.

Part Context

This part belongs to the CD46xx series of voltage regulator diode chips. It is functionally interchangeable with the widely used 1N4678 through 1N4717 discrete diode family. The chip format allows for integration into custom hybrid circuits or specialized semiconductor packages where standard leaded components are impractical.

Replacement Considerations

Direct substitutes include the 1N4678, 1N4679, 1N4680, 1N4681, 1N4682, 1N4683, 1N4684, 1N4685, 1N4686, 1N4687, 1N4688, 1N4689, 1N4690, 1N4691, 1N4693, 1N4694, 1N4695, 1N4696, 1N4697, 1N4698, 1N4699, 1N4700, 1N4701, 1N4702, 1N4703, and 1N4704.
