1N3014RB

Overview

The 1N3014RB is a 10-watt Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 24 volts with a tolerance of ±5%. The device is designed for base and stud mounting applications, utilizing the DO-213AA (DO-4) package. It operates within a temperature range of -65°C to +175°C junction temperature. Key electrical characteristics include a maximum impedance of 5 ohms at the test current and a reverse leakage current of 10 µA at 18.2 volts. The forward voltage drop is specified as 1.5 volts at 2 amperes.

Feature Summary

• High power dissipation capability rated at 10 watts for robust voltage regulation in demanding environments.
• Extended thermal operating range supporting junction temperatures from -65°C to +175°C.
• Qualified per MIL-PRF-19500/124 standards for JAN, JANTX, and JANTXV levels.

Applications

• Voltage regulation in military and aerospace electronic systems requiring high reliability.
• Overvoltage protection circuits in industrial equipment exposed to harsh environmental conditions.
• Reference voltage sources in precision instrumentation where stable 24-volt regulation is required.

Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application, as these levels correspond to different manufacturing standards and testing rigor. Confirm that the DO-213AA package style matches your board layout or chassis mounting constraints. Ensure that the thermal management design accounts for the 10-watt power dissipation rating to maintain junction temperatures within the specified -65°C to +175°C operational range during continuous operation.

Selection Notes

Select this component when a 24-volt Zener reference with high power handling is necessary. The 1N3014RB is suitable for applications requiring strict compliance with MIL-PRF-19500/124 standards. Consider the physical size of the DO-4 package and the need for stud or base mounting hardware. Evaluate the 5-ohm impedance specification against the dynamic load requirements of your circuit to ensure adequate regulation performance under varying current conditions.

Part Context

The 1N3014RB belongs to the 1N2970B through 1N3015B series of 10-watt Zener diodes produced by Microchip Technology. This series covers a wide range of voltage regulation values from 3.9 to 200 volts. These devices are part of Microchip's portfolio of qualified discrete semiconductors designed for high-reliability applications in defense, aerospace, and industrial sectors where standard commercial components may not suffice.

Replacement Considerations

Compatible substitutes include other 10-watt Zener diodes with a 24-volt nominal rating and ±5% tolerance in a DO-4 package. Verify that any replacement meets the same MIL-PRF-19500/124 qualification level if military-grade reliability is mandated. Ensure the replacement device maintains equivalent thermal characteristics and impedance specifications to guarantee circuit compatibility without redesign.
