Overview
The Microchip Technology 1N3006RB is a 10W Zener diode with a nominal voltage of 68V and a 5% tolerance. It operates within a junction temperature range of -65°C to +175°C and features a maximum dynamic impedance of 22 Ohms at the test current of 33mA. The device utilizes a DO-4 (DO-213AA) stud mount package with reverse polarity, where the cathode connects to the stud. It is qualified per MIL-PRF-19500/124 for JAN, JANTX, and JANTXV grades.
Feature Summary
- Hermetically sealed welded metal and glass construction with internal solder bond.
- Reverse polarity configuration with cathode connected to the mounting stud.
- Inherently radiation hard design suitable for harsh environments.
- ESD nonsensitive performance verified per MIL-STD-750 method 1020.
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 the specific qualification grade (JAN, JANTX, or JANTXV) required for your application, as availability varies by voltage value. Confirm that the reverse polarity orientation (cathode to stud) aligns with your mechanical assembly constraints. Ensure thermal management meets the derating requirements above +55°C case temperature to maintain the 10W power dissipation rating safely.
Selection Notes
Select this component when a 68V regulation point is needed in a high-power, ruggedized environment. The DO-4 stud mount facilitates direct heat sinking to chassis structures. Consider the reverse polarity requirement carefully, as it differs from standard axial diodes. Verify that the operating temperature range and radiation hardness meet the system specifications before finalizing the design.
Part Context
This part belongs to the 1N2970B through 1N3015B series of 10W Zener diodes manufactured by Microsemi (now Microchip). These devices are JEDEC registered and designed for demanding industrial and military applications. The series offers a wide voltage range from 3.9V to 200V with standard 5% tolerances.
Replacement Considerations
Direct substitutes must match the 10W power rating, 68V Zener voltage, DO-4 package, and reverse polarity. Verify MIL-PRF-19500/124 qualification equivalence if military grades are specified. Cross-reference with other manufacturers offering hermetically sealed stud-mount Zener diodes with identical electrical characteristics.
FAQ
What does the 'RB' suffix indicate on the 1N3006RB?
The 'RB' suffix indicates reverse polarity, meaning the cathode is connected to the mounting stud instead of the anode.
Is the 1N3006RB radiation hard?
Yes, the device is inherently radiation hard as described in Microsemi MicroNote 050.
How is the 1N3006RB packaged?
It is housed in a DO-4 (DO-213AA) industry-standard hex stud package with welded, hermetically sealed metal and glass construction.
