Product details
Overview
JANTXV1N4111D-1 from Microsemi is a 500 mW, 17.0 V ±1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability applications. It delivers stable voltage regulation at 250 mA test current with 100 Ω dynamic impedance, 0.05 µA max reverse leakage at 13.0 V, and +0.090 %/°C temperature coefficient.
For engineers reviewing the JANTXV1N4111D-1 datasheet, JANTXV1N4111D-1 pinout, JANTXV1N4111D-1 application, or JANTXV1N4111D-1 equivalent, key selection criteria include its 1% Zener tolerance, hermetic glass packaging, radiation-hardened construction, low noise density (1 µV/√Hz), and military-grade thermal derating profile up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, critical for aerospace and defense systems requiring MIL-PRF-19500/435 JANTXV qualification.
The diode exhibits a positive temperature coefficient (+0.090 %/°C) above 10 V, enabling predictable drift compensation in reference circuits. Its 100 Ω dynamic impedance at 250 mA and 13.0 V Zener voltage supports stable regulation across load current variations while maintaining low capacitance (<2 pF typical per Figure 3).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US-1 | Same 17.0 V ±1% Zener, but in DO-213AA surface-mount package | Requires SMT reflow process instead of through-hole assembly; no axial lead handling | Select for space-constrained PCBs where automated placement is preferred over manual insertion |
| JANTXV1N4111-1 | Same electrical specs but ±5% Zener tolerance instead of ±1% | Lacks tight initial accuracy needed for metrology-grade references | Select only when cost sensitivity outweighs requirement for 1% tolerance in non-critical regulation |
Compared with JANTXV1N4111D-1, the JANTXV1N4111-1 offers lower cost but sacrifices initial accuracy, while the 1N4111US-1 retains full spec compliance in a surface-mount form factor-neither is pin-compatible due to differing packages, and both require layout revision.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4111D-1?
JANTXV1N4111D-1 has a nominal Zener voltage of 17.0 V with ±1% tolerance, measured at 250 mA test current and 25 °C ambient. This tight tolerance is achieved via post-process screening and is specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. The "D" suffix in JANTXV1N4111D-1 explicitly denotes the 1% tolerance grade.
Is JANTXV1N4111D-1 suitable for high-temperature operation?
Yes, JANTXV1N4111D-1 is rated for junction temperatures from –65 to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgically bonded DO-35 glass package maintains parameter stability under thermal cycling, making it suitable for engine bay, avionics bay, and downhole electronics where sustained high-temperature operation is required.
Does JANTXV1N4111D-1 have radiation hardness certification?
Yes, JANTXV1N4111D-1 is inherently radiation hard per Microsemi MicroNote 050, a documented characteristic of its metallurgically bonded construction and hermetic glass package. While not individually tested per MIL-STD-883 Method 1019, its family-level radiation performance is validated for total ionizing dose (TID) environments common in low-earth orbit and nuclear instrumentation applications.
What is the maximum reverse leakage current for JANTXV1N4111D-1?
JANTXV1N4111D-1 has a maximum reverse leakage current (IR) of 0.05 µA at 13.0 V (75% of VZ), as specified in the Electrical Characteristics table. This ultra-low leakage ensures minimal error current in high-impedance reference divider networks and preserves accuracy in battery-powered or low-power monitoring circuits using JANTXV1N4111D-1.
Can JANTXV1N4111D-1 be used in surface-mount designs?
No, JANTXV1N4111D-1 uses the axial-leaded DO-35 (DO-204AH) through-hole package and is not compatible with surface-mount assembly. For SMT equivalents, consider the 1N4111US-1 in DO-213AA package - it shares identical electrical specifications including 17.0 V ±1% Zener voltage but requires PCB redesign to accommodate the surface-mount footprint and reflow profile for JANTXV1N4111D-1 replacement.
