1N3001B

Overview

The Microchip Technology 1N3001B-1 is a 1-watt Zener diode with a nominal voltage of 5.1 V and a tolerance of ±5%. It utilizes a DO-204AL (DO-41) axial through-hole package. The device operates within a temperature range of -65°C to +175°C and features a maximum impedance of 80 Ohms at the test current.

Feature Summary

• Metalurgically bonded construction for robust performance
• Wide operating temperature range suitable for harsh environments
• Standard axial through-hole packaging for easy integration

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications in power supplies

Procurement Notes

Verify the specific suffix, such as -1, JAN, JANTX, or JANTXV, as these indicate different qualification levels per MIL-PRF-19500/115. Confirm the exact voltage tolerance and impedance requirements against the datasheet electrical characteristics table before ordering to ensure compatibility with the target circuit design.

Selection Notes

Select this component when a standard 5.1 V Zener breakdown is required with high thermal stability. The DO-41 package supports up to 1 Watt of power dissipation. Ensure the application environment stays within the specified -65°C to +175°C range to maintain reliability and prevent derating issues above 95°C.

Part Context

This part belongs to the 1N3016B through 1N3045B series of 1-watt Zener diodes manufactured by Microchip. These devices are metallurgically bonded and available in various voltage ratings from 16V to 45V. The series is designed for general-purpose regulation and protection tasks requiring reliable performance across wide temperature extremes.

Replacement Considerations

Equivalent parts include other 5.1V 1W Zener diodes in DO-41 packages. Verify that replacement components meet the same MIL-PRF-19500/115 specifications if military-grade qualification is required. Check for matching impedance and leakage current values.
