Overview
The MCC 1N4699-TP is a 500mW silicon Zener diode housed in a DO-35 axial leaded package. It provides a nominal Zener voltage of 12V with a standard tolerance of ±5%. The device features a maximum forward voltage of 1.5V at 100mA and operates within a junction temperature range of -65°C to 200°C. It utilizes a double slug type, hermetically sealed glass construction.
Feature Summary
- Hermetically sealed glass construction for high reliability
- Sharp reverse characteristic for precise voltage regulation
- Standard ±5% tolerance on nominal Zener voltage
Applications
- Voltage regulation over broad operating current ranges
- Reference voltage sources in electronic circuits
- Protection against transient voltage spikes
Procurement Notes
Verify the specific suffix (TP) corresponds to the Tape & Reel packaging format as defined by the manufacturer's ordering information. Confirm that the component meets RoHS compliance standards and check for any lead-in-glass exemptions applicable to the glass package material before finalizing procurement specifications.
Selection Notes
Select this component when a 12V reference is required in an axial leaded form factor. Ensure the application can accommodate the 500mW power dissipation limit and verify that the ±5% voltage tolerance aligns with the circuit's precision requirements. Consider thermal management if operating near the maximum junction temperature limits.
Part Context
This part belongs to the 1N4678 through 1N4717 series of 500mW silicon Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 1.8V to 43V, offering standardized tolerances and reliable performance for general-purpose voltage regulation applications in commercial electronics.
Replacement Considerations
Direct replacements must match the 12V nominal Zener voltage, 500mW power rating, and DO-35 axial package. Verify that substitute components maintain similar reverse leakage characteristics and forward voltage drops to ensure circuit compatibility without redesign.
