1N4962E3

Overview

The Microchip Technology 1N4962E3 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V and operates with a test current of 75 mA. The device supports a maximum power dissipation of 5 W and maintains a voltage tolerance of 5%. Electrical characteristics include a maximum reverse leakage current of 2 uA and a Zener impedance of 8 Ohms. The component is rated for operation within an ambient temperature range from -65 °C to +175 °C, ensuring reliability in demanding environments.

Feature Summary

• Provides stable voltage regulation through precise Zener breakdown characteristics
• Supports high-temperature operation up to 175 °C for extended environmental resilience
• Utilizes axial lead-through-hole mounting for robust mechanical integration

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• Power supply regulation modules

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package style and compliance status. Ensure the selected variant matches the required axial lead configuration and thermal rating for your design. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a 15 V regulation point is required with high thermal stability. The 5 W power rating allows for significant current handling compared to lower-power alternatives. Verify that the 8 Ohm impedance meets the noise and regulation requirements of the target application circuit.

Part Context

This component belongs to the standard Zener diode family manufactured by Microchip Technology. It utilizes the industry-standard 1N49xx numbering convention for identification. The E3 suffix typically indicates lead-free composition and RoHS compliance, distinguishing it from older non-compliant variants within the same electrical specification family.

Replacement Considerations

Consult official substitution guides for compatible equivalents. Generic replacements must match the 15 V Zener voltage, 5 W power dissipation, and axial package dimensions to ensure functional parity without redesigning the host circuit board.
