Product details
Overview
1N4106/TR from Microsemi is a 500 mW, 12.0 V ±5% axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTX level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance and +0.080 %/°C temperature coefficient, used in precision reference and power supply feedback circuits.
For engineers reviewing the 1N4106/TR datasheet, 1N4106/TR pinout, 1N4106/TR application, or 1N4106/TR equivalent, this page provides verified Zener voltage, thermal derating behavior, noise density, RoHS compliance status, and military-grade qualification details essential for high-reliability analog design and aerospace power systems.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction ensuring low leakage and radiation hardness. Its 12.0 V nominal Zener voltage is specified at IZT = 250 mA, with IR ≤ 0.05 µA at VR = 9.2 V and ZZT = 200 Ω measured at 10% AC modulation of IZT.
The diode exhibits +0.080 %/°C temperature coefficient above 10 V, enabling predictable drift compensation in temperature-stable references. Thermal resistance junction-to-lead is 250 °C/W at 10 mm lead length, supporting reliable operation up to TJ = +175 °C when mounted per JEDEC guidelines.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V ±5%, 1 W rating, DO-41 package, 200 Ω ZZT, +0.075 %/°C tempco | Higher power but larger footprint; not mil-qualified | Select for cost-sensitive commercial designs requiring higher dissipation margin |

FAQ
What is the Zener voltage tolerance for 1N4106/TR?
The 1N4106/TR has a nominal Zener voltage of 12.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered electrical characteristics table. This tolerance applies at IZT = 250 mA and TA = +25 °C, and is confirmed in the T4-LDS-0245-2 datasheet revision 1. The 1N4106/TR does not include tighter-tolerance variants (e.g., C or D suffixes) in its standard nomenclature.
Is 1N4106/TR RoHS compliant?
Yes, the 1N4106/TR is RoHS compliant when ordered with the "e3" suffix (e.g., 1N4106-1e3/TR), which denotes RoHS-compliant matte-tin plating on commercial-grade devices. Per the datasheet, RoHS compliance is available only for commercial versions-not JAN, JANTX, JANTXV, or JANS levels-and is solderable per MIL-STD-750 method 2026.
What is the maximum reverse leakage current for 1N4106/TR?
The maximum reverse leakage current (IR) for 1N4106/TR is 0.05 µA at VR = 9.2 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This value is measured at +25 °C and reflects the diode's low-leakage performance critical for high-impedance reference applications.
Does 1N4106/TR have radiation hardness certification?
Yes, the 1N4106/TR is inherently radiation hard per Microsemi MicroNote 050, due to its metallurgically bonded construction and hermetic glass packaging. While not individually tested per MIL-STD-883, its process and structure are documented to withstand total ionizing dose (TID) levels appropriate for space and nuclear applications-confirmed in the "Applications / Benefits" section of the datasheet.
What is the thermal resistance junction-to-lead for 1N4106/TR?
The thermal resistance junction-to-lead (RθJL) for 1N4106/TR is 250 °C/W, measured at 3/8 inch (10 mm) lead length from the body, per the Maximum Ratings table. This value assumes standard mounting on FR4 PCB with 4 mm² copper pads and is essential for calculating junction temperature rise under actual operating power dissipation.
