Overview
The 1N4962US/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It features a nominal Zener voltage of 15 V with a tolerance of ±5%. The device supports a maximum power dissipation of 5 W and operates within a temperature range up to +175°C. Packaged in the SQ-MELF (D-5B) form factor, it is supplied in tape and reel format for automated assembly processes.
Feature Summary
- Surface-mount construction in an SQ-MELF package
- High thermal stability supporting operation up to +175°C
- Single-channel Zener regulation capability
Applications
- Voltage regulation in high-temperature electronic circuits
- Overvoltage protection for sensitive components
- Reference voltage sources in industrial equipment
Procurement Notes
Verify the specific ordering suffix and manufacturer lot codes against current Microchip Technology documentation to ensure authenticity. Confirm that the SQ-MELF package dimensions match your PCB footprint requirements. Check for any recent design changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a 15 V Zener reference is required in a compact surface-mount configuration. Ensure the circuit design accommodates the 5 W power rating and the specific thermal characteristics of the SQ-MELF package. Verify compatibility with automated pick-and-place equipment due to the tape and reel packaging format.
Part Context
This part belongs to the 1N4962 series of Zener diodes produced by Microchip Technology. It shares functional similarities with other devices in the 1N49xx family but is distinguished by its specific voltage rating and surface-mount packaging. The US/TR suffix indicates the specific package type and reel packaging method used for distribution.
Replacement Considerations
Direct substitutes include JANS1N4962CUS/TR and JANTXV1N4962DUS/TR from Microchip, which offer similar electrical specifications but may differ in qualification levels or packaging details. Always verify pinout and thermal performance before substitution.
