Overview
The Microchip Technology 1N4699E3/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 12 V with a tolerance of ±5%. The device operates in a DO-35 axial through-hole package and supports a maximum power dissipation of 500 mW. It maintains an operating temperature range from -65 °C to +175 °C junction temperature. The component is supplied in tape and reel packaging.
Feature Summary
- Provides stable voltage regulation via Zener breakdown characteristics
- Supports high-temperature operation up to 175 °C junction temperature
- Utilizes glass-passivated die for enhanced stability
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific suffix E3 indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the TR suffix denotes tape and reel packaging suitable for automated assembly processes. Cross-reference the full part number against official Microchip documentation to ensure compatibility with design requirements before procurement.
Selection Notes
Select this component when a 12 V regulation point is required within a through-hole design. Ensure the circuit current does not exceed limits that would cause power dissipation beyond 500 mW. Verify that the ±5% voltage tolerance aligns with system precision needs. Consider the DO-35 package dimensions for board layout constraints.
Part Context
This part belongs to the standard Zener diode family manufactured by Microchip Technology. It shares common electrical characteristics with other devices in the series, differentiated primarily by their specific Zener voltage ratings. The 1N4699 variant specifically targets the 12 V regulation segment within the broader portfolio.
Replacement Considerations
Consult official substitution lists for equivalent parts with matching voltage and power ratings. Verify pinout compatibility and package dimensions if replacing with components from other manufacturers.
