Overview
The Central Semiconductor Corp 1N4690 TR TIN/LEAD is a low-level Zener diode designed for voltage regulation and reference applications. It operates within a Zener voltage range of 5.32V to 5.88V at a test current of 50mA. The device features a power dissipation rating of 350mW and utilizes an SOT-23 surface-mount package. This component belongs to the CMPZ4 series, offering stable performance for general-purpose circuit protection and signal conditioning tasks in compact electronic designs.
Feature Summary
- Provides precise voltage regulation within a narrow tolerance band suitable for sensitive reference circuits
- Utilizes a compact SOT-23 surface-mount footprint to facilitate automated assembly and space-constrained layouts
- Engineered for low-power operation with a 350mW dissipation rating ideal for signal-level applications
Applications
- Voltage reference sources in precision measurement equipment
- Over-voltage protection for low-current signal lines
- Biasing networks in transistor amplifier stages
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm lead-free versus tin/lead plating specifications, as these variants may differ in compliance status and physical characteristics. Ensure the selected reel quantity aligns with production requirements and that the component meets RoHS directives if applicable to the target market. Cross-reference datasheet electrical limits with system operating conditions before finalizing procurement.
Selection Notes
Select this component when a stable voltage reference near 5.5V is required in a small surface-mount form factor. Consider the 350mW power rating and 50mA test current to ensure adequate thermal headroom and regulation accuracy for the intended load. Evaluate the SOT-23 package compatibility with existing PCB footprints and assembly processes compared to through-hole alternatives.
Part Context
This part belongs to the CMPZ4 series of low-level Zener diodes manufactured by Central Semiconductor. The series focuses on providing reliable voltage regulation in compact packages for consumer and industrial electronics. The 1N4690 designation corresponds to a specific voltage bin within this lineup, offering consistency for mass-production environments requiring standardized voltage references.
Replacement Considerations
Consult official substitution guides for compatible equivalents such as other CMPZ4 series variants or industry-standard 1N46xx replacements. Verify pinout compatibility and electrical parameter overlaps, particularly Zener voltage tolerance and power dissipation ratings, before implementing any alternative components in the design.
