Overview
The Central Semiconductor Corp 1N4691 TR TIN/LEAD is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.2V with a tolerance of 5%. The device is rated for a power dissipation of 0.5W and operates within a temperature range up to 175°C. It utilizes the DO-35 axial-leaded glass package, providing an isolated case connection. The component is unidirectional and contains a single junction.
Feature Summary
- Provides stable voltage regulation at a nominal 6.2V level
- Constructed with silicon material for reliable performance
- Features an internal metallurgical bond similar to military requirements
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify that the specific ordering suffix corresponds to the tin/lead plating and tape-and-reel packaging format required for your assembly process. Confirm RoHS compliance status as the base part may be non-compliant depending on the specific manufacturer variant. Ensure the supplier provides official datasheets matching the exact part number to validate electrical parameters before procurement.
Selection Notes
Select this component when a 6.2V regulation point is required in a through-hole axial package. Consider the 0.5W power rating and 175°C maximum operating temperature for thermal management. Verify compatibility with existing circuit designs requiring low-level Zener regulation in standard DO-35 footprints.
Part Context
This part belongs to the 1N4678-1 through 1N4717-1 series of 0.5-watt Zener voltage regulators. These devices offer a selection of voltages from 1.8 to 43 volts with standard 5% tolerances. The series is characterized by axial-leaded glass construction and internal metallurgical bonding, originally developed for commercial versions of military-specified components.
Replacement Considerations
Equivalent parts include other manufacturers' 1N4691 variants in DO-35 packages. Verify pinout orientation and voltage tolerance matches the original design requirements.
