Product details
Overview
JANTX1N4106-1/TR from Microsemi is a 500 mW, 12.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4106-1/TR datasheet, JANTX1N4106-1/TR pinout, JANTX1N4106-1/TR application, or JANTX1N4106-1/TR equivalent, key selection factors include its 12.0 V nominal Zener voltage at 250 mA test current, 200 Ω maximum dynamic impedance, 0.05 µA maximum reverse leakage at 9.2 V, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with a fixed 12.0 V breakdown threshold, designed for stable reference generation under varying load and temperature conditions. Its metallurgical bond construction ensures low noise density (1 µV/√Hz typical at lower voltages) and inherent radiation hardness per Microsemi MicroNote 050.
The JANTX1N4106-1/TR exhibits a +0.080 %/°C temperature coefficient of Zener voltage and is rated for 40 mA maximum Zener current at 25 °C ambient, with linear derating to zero power at 175 °C junction temperature. It features hermetically sealed glass packaging and cathode band polarity marking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4106US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole or wire-wrap prototyping | Select when board space is constrained and reflow compatibility is mandatory |
| JAN1N4106-1 | Identical electrical and mechanical specs but qualified only to JAN level (less rigorous screening than JANTX) | Acceptable for non-safety-critical commercial-military hybrids where full JANTX screening is not mandated | Select when cost sensitivity outweighs requirement for extended burn-in and lot traceability |
Compared with JANTX1N4106-1/TR, the 1N4106US-1 enables PCB area reduction via SMT integration but sacrifices manual repairability, while the JAN1N4106-1 reduces procurement cost and lead time at the expense of reduced reliability screening depth for mission-critical subsystems.

FAQ
What is the Zener voltage tolerance for JANTX1N4106-1/TR?
JANTX1N4106-1/TR has a nominal Zener voltage of 12.0 V with a ±5% tolerance, consistent with the standard JEDEC 1N4106-1 specification and verified per MIL-PRF-19500/435 JANTX screening requirements. This tolerance applies at 250 mA test current and 25 °C ambient temperature.
Is JANTX1N4106-1/TR RoHS compliant?
No, JANTX1N4106-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4106-1e3). JANTX1N4106-1/TR uses traditional tin-lead plating per MIL-STD-750 and is intended for legacy military applications where Pb exemption applies.
What is the maximum Zener current rating for JANTX1N4106-1/TR?
JANTX1N4106-1/TR is rated for a maximum Zener current (IZM) of 40 mA at 25 °C ambient temperature. This value is derived from its 500 mW power rating and 12.0 V nominal Zener voltage, and must be linearly derated above 50 °C lead temperature per Figure 2 in the datasheet.
Does JANTX1N4106-1/TR have radiation hardness certification?
Yes, JANTX1N4106-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction provides resistance to total ionizing dose (TID) and single-event effects without requiring additional shielding or derating for space or nuclear applications.
What does the "TR" suffix mean in JANTX1N4106-1/TR?
The "TR" suffix in JANTX1N4106-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This version contains the same die, qualification, and electrical specifications as the bulk-packaged JANTX1N4106-1, with no functional or reliability differences.
