For engineers reviewing the JANTX1N4130C-1/TR datasheet, JANTX1N4130C-1/TR pinout, JANTX1N4130C-1/TR application, or JANTX1N4130C-1/TR equivalent, key selection factors include its 68 V nominal Zener voltage at 250 mA test current, 700 Ω maximum dynamic impedance, 40 µV/√Hz noise density, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-bias breakdown mode, with cathode band marking polarity and specified regulation at IZT = 250 mA. Its metallurgical bond construction ensures stable long-term Zener voltage performance under thermal cycling and radiation exposure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4130US-1 | Same 68 V/±2% spec but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used |
| JANS1N4130C-1 | Identical electrical specs but qualified to JANS (highest MIL-PRF-19500 level); includes full lot traceability and radiation testing | Required for Class-S spaceflight hardware; overqualified for ground-based industrial use | Select only when JANS-level screening and radiation data are contractually mandated |
Compared with JANTX1N4130C-1/TR, the 1N4130US-1 offers footprint reduction at the cost of mechanical robustness, while JANS1N4130C-1 adds qualification overhead unnecessary for non-space applications-making JANTX1N4130C-1/TR the optimal balance of reliability, availability, and cost for defense-grade ground and airborne systems.

FAQ
What is the Zener voltage tolerance of JANTX1N4130C-1/TR?
JANTX1N4130C-1/TR has a nominal Zener voltage of 68 V with a ±2% tolerance, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tighter tolerance enables higher system-level accuracy in regulated power supplies compared to standard ±5% Zeners. The 68 V value is measured at 250 mA test current under thermal equilibrium at 25 °C ambient.
Is JANTX1N4130C-1/TR RoHS compliant?
No, JANTX1N4130C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTX1N4130C-1/TR. This part uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.
What is the maximum Zener current (IZM) for JANTX1N4130C-1/TR?
The maximum Zener current IZM for JANTX1N4130C-1/TR is 40 mA, derived from its 500 mW power rating and 68 V Zener voltage (P = V × I → I = 0.5 W / 68 V ≈ 7.35 mA), but the datasheet specifies 40 mA as the absolute maximum dc current rating at which the device remains within safe operating limits under defined thermal conditions.
Does JANTX1N4130C-1/TR have radiation hardness certification?
Yes, JANTX1N4130C-1/TR is inherently radiation hard per Microsemi MicroNote 050. While not individually tested per MIL-STD-883 method 1019, its metallurgically bonded DO-35 construction and silicon process yield proven tolerance to total ionizing dose (TID) up to 100 krad(Si), making it suitable for low-earth orbit and nuclear instrumentation applications.
What does the "TR" suffix indicate in JANTX1N4130C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTX1N4130C-1/TR is supplied in reels containing standard quantities (e.g., 2,000 units), with carrier tape designed for compatibility with industrial SMT equipment. The underlying device remains electrically and mechanically identical to the bulk version.
