For engineers reviewing the JANTXV1N4117D-1/TR datasheet, JANTXV1N4117D-1/TR pinout, JANTXV1N4117D-1/TR application, or JANTXV1N4117D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), junction temperature range (–65 to +175 °C), metallurgical bond construction, MIL-PRF-19500/435 JANTXV qualification, and low noise density (1 µV/√Hz).
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable output voltage across wide current and temperature ranges. It features an internal metallurgical bond for enhanced reliability and low leakage, with specified reverse current ≤0.01 µA at 19.0 V and dynamic impedance of 150 Ω measured at IZT = 250 mA.
Designed for high-reliability environments, the JANTXV1N4117D-1/TR meets MIL-PRF-19500/435 Class JANTXV requirements, supports operation from –65 °C to +175 °C, and exhibits minimal capacitance (typical <2 pF) and low noise density - critical for analog reference stability in avionics and space-grade instrumentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4117US-1TR | Same 25 V, 1% Zener voltage but in surface-mount DO-213AA package | Requires PCB re-layout for SMT assembly; no axial lead option | Select when automated placement and board space reduction are prioritized over through-hole serviceability |
| JANS1N4117D-1 | Identical electrical specs but qualified to JANS level (higher screening, extended temp range validation) | Approved for mission-critical space systems where JANTXV is insufficient | Select only when full JANS qualification documentation and lot traceability are contractually required |
Compared with JANTXV1N4117D-1/TR, the 1N4117US-1TR offers identical regulation performance in a smaller footprint but sacrifices axial-leaded serviceability, while JANS1N4117D-1 adds rigorous radiation and burn-in testing - increasing cost and lead time without improving baseline Zener characteristics.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4117D-1/TR?
JANTXV1N4117D-1/TR has a nominal Zener voltage of 25.0 V with a ±1% tolerance, verified per MIL-PRF-19500/435 test conditions at IZT = 250 mA and 25 °C. This tolerance is achieved via post-process binning and applies across the full operating temperature range of –65 to +175 °C.
Is JANTXV1N4117D-1/TR qualified to MIL-PRF-19500/435?
Yes, JANTXV1N4117D-1/TR is qualified to MIL-PRF-19500/435 Class JANTXV, including full screening for thermal shock, vibration, hermeticity, and electrical parameters. The "JANTXV" prefix in the part number explicitly denotes this qualification level per Microsemi's nomenclature standard.
What is the maximum power dissipation rating for JANTXV1N4117D-1/TR?
JANTXV1N4117D-1/TR is rated for 500 mW average power dissipation at 25 °C lead temperature. Power must be linearly derated starting at 50 °C lead temperature, reaching zero at 175 °C - consistent with its RθJL = 250 °C/W thermal resistance specification.
Does JANTXV1N4117D-1/TR have low noise performance?
Yes, JANTXV1N4117D-1/TR delivers 1 µV/√Hz noise density at 250 mA Zener test current, confirmed in Microsemi's T4-LDS-0245-2 datasheet. This low noise is intrinsic to its metallurgically bonded structure and enables use in high-fidelity analog reference paths where voltage ripple must be minimized.
What package type does JANTXV1N4117D-1/TR use?
JANTXV1N4117D-1/TR uses the DO-35 (DO-204AH) hermetically sealed axial-leaded glass package, with cathode identified by a band on the body. Lead plating is tin-lead or RoHS-compliant matte-tin, and the device weighs approximately 0.2 grams.
