1N3013RB

Overview

The Microchip Technology 1N3013RB is a 10W Zener diode with a nominal voltage of 175V and a standard tolerance of ±5%. It operates within a junction temperature range of -65°C to +175°C. The device features a DO-213AA (DO-4) package with reverse polarity, where the cathode connects to the stud. Maximum dynamic impedance at test current is 250 Ω, and maximum reverse current is 10 µA.

Feature Summary

• Hermetically sealed welded construction with internal solder bond for reliability.
• Reverse polarity configuration with cathode connected to the metal stud.
• Qualified per MIL-PRF-19500/124 for JAN, JANTX, and JANTXV grades.
• Inherently radiation hard and nonsensitive to ESD.

Applications

• Voltage regulation over broad current and temperature ranges.
• Military and aerospace electronic systems requiring high reliability.
• Radiation-hardened circuit protection applications.

Procurement Notes

Verify that the specific order includes the correct military qualification grade (JAN, JANTX, or JANTXV), as availability varies by voltage value. Confirm RoHS compliance status, noting that the e3 suffix applies only to commercial grade devices. Ensure mounting hardware requirements are addressed separately if insulators or bushings are needed for the stud mount.

Selection Notes

Select this component when a 175V regulation point is required in a ruggedized environment. The reverse polarity design suits applications where the stud must be electrically isolated from the anode. Verify thermal management capabilities, as steady-state power dissipation requires derating above +55°C case temperature. Consult factory for surface mount equivalents or tighter tolerances than the standard ±5%.

Part Context

This part belongs to the JEDEC registered 1N2970B through 1N3015B series of 10W Zener diodes. These components provide voltage regulation values between 3.9V and 200V. The series is widely used in industrial and defense sectors due to its robust mechanical construction and stable electrical characteristics across extreme temperatures.

Replacement Considerations

Direct substitutes include other parts from the 1N2970B–1N3015B series with matching voltage and polarity. Equivalent replacements must maintain the DO-4 package form factor and hermetic sealing. Verify that any alternative meets the same MIL-PRF-19500/124 qualification levels if military-grade performance is required.
