Product details
Overview
1N3006RB from Microsemi is a 10 W hermetically sealed, stud-mounted Zener diode with nominal Zener voltage 105 V at 25 mA test current, ±5% tolerance, and reverse polarity (cathode-to-stud). It operates from –65 °C to +175 °C junction temperature and delivers stable voltage regulation in high-reliability power supply and overvoltage protection circuits for aerospace and defense systems.
For engineers reviewing the 1N3006RB datasheet, 1N3006RB pinout, 1N3006RB application, or 1N3006RB equivalent, key selection criteria include its DO-213AA (DO-4) metal-glass package, 12 °C/W junction-to-case thermal resistance, 75 mA maximum Zener current at 25 °C, +0.095 %/°C temperature coefficient, and MIL-PRF-19500/124 JANTXV qualification readiness.
Technical Context
This device functions as a precision voltage reference and shunt regulator in high-stability DC power conditioning. Its welded metal-glass construction ensures hermetic sealing and inherent radiation hardness per Microsemi MicroNote 050, while internal solder bond construction supports robust thermal cycling performance.
The 1N3006RB exhibits 75 Ω dynamic impedance at 25 mA (ZZT), 10 µA reverse leakage at 76 V (VR), and a forward voltage of 1.5 V at 2.0 A - enabling reliable clamping and regulation across wide current and temperature ranges without external biasing circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 105 V ±5% at IZT = 25 mA - defines regulated output voltage under standard test conditions |
| Power Dissipation (PD) | 10 W @ TC = +55 °C - sets maximum continuous thermal load at stud temperature |
| Junction-to-Case Thermal Resistance (RθJC) | 12 °C/W - determines temperature rise per watt dissipated; critical for heatsink sizing |
| Dynamic Impedance (ZZT) | 75 Ω @ 25 mA - indicates regulation stiffness; lower values improve line/load regulation |
| Temperature Coefficient (αVZ) | +0.095 %/°C - quantifies voltage drift with temperature; enables compensation design |
| Reverse Leakage Current (IR) | 10 µA @ 76 V - defines minimum off-state current; impacts standby power loss |
| Forward Voltage (VF) | 1.5 V @ 2.0 A - specifies conduction drop during forward-biased fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N3006B | Standard polarity (anode-to-stud); identical electrical specs except terminal assignment | Requires reversed mounting orientation; incompatible with existing cathode-to-stud PCB layouts | Select only when mechanical layout permits anode connection to heatsink |
| 1N3006JANTXV | Same polarity and specs as 1N3006RB but qualified to JANTXV level per MIL-PRF-19500/124 | Required for flight hardware where full military screening (burn-in, life test, lot acceptance) is mandated | Choose when program requirements specify JANTXV-level reliability documentation and traceability |
Compared with 1N3006B and 1N3006JANTXV, the 1N3006RB uniquely combines reverse polarity (cathode-to-stud) with commercial-grade availability and RoHS-compliant variants (e3 suffix), making it optimal for high-reliability terrestrial systems needing simplified thermal mounting without full military screening overhead.

FAQ
What does the "RB" suffix mean in 1N3006RB?
The "RB" suffix in 1N3006RB denotes reverse polarity: cathode is connected to the metal stud, while the lead wire serves as the anode. This configuration simplifies thermal mounting to a heatsink or chassis when the cathode must be at system ground potential, and differs from the standard "B" variant where the anode connects to the stud.
What is the maximum steady-state power dissipation for 1N3006RB?
The 1N3006RB has a steady-state power dissipation rating of 10 W at case (studs) temperature of +55 °C. Above this temperature, power must be linearly derated at 0.083 W/°C, reaching zero at +175 °C - a limit defined by its 12 °C/W junction-to-case thermal resistance and silicon process limits.
Is 1N3006RB qualified to MIL-PRF-19500/124?
Yes, the 1N3006RB is available in JAN, JANTX, and JANTXV reliability levels qualified per MIL-PRF-19500/124. The base part number supports all three levels; qualification level is indicated by the prefix (e.g., JANTXV 1N3006RB), not the suffix. Commercial versions omit the prefix but retain identical electrical and mechanical specs.
What is the Zener impedance of 1N3006RB and why does it matter?
The 1N3006RB has a dynamic impedance (ZZT) of 75 Ω at 25 mA test current. This value reflects how tightly the device regulates voltage under varying load - lower impedance yields smaller output voltage deviations during current transients, which is essential for precision reference and feedback applications in switching power supplies.
Can 1N3006RB be used in radiation-intensive environments?
Yes, the 1N3006RB exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. Its hermetically sealed metal-glass construction and silicon process provide tolerance to total ionizing dose (TID) without parameter shift or functional failure - making it suitable for space, nuclear, and high-altitude applications where radiation-induced degradation must be avoided.
