Product details
Overview
JANTX1N4617C-1/TR from Microsemi is a 2.4 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 1400 Ω dynamic impedance at 250 mA test current, and 1 µV/√Hz noise density - used for precision voltage regulation in military-grade power supply references and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4617C-1/TR datasheet, JANTX1N4617C-1/TR pinout, JANTX1N4617C-1/TR application, or JANTX1N4617C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), MIL-qualified reliability (JANTX), thermal resistance (250 °C/W junction-to-lead), and DO-35 axial-leaded hermetic packaging for high-reliability analog reference designs.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 2.4 V at 250 mA test current (IZT), exhibiting a temperature coefficient of –0.075 %/°C and dynamic impedance of 1400 Ω under specified bias conditions. Its metallurgical bond construction ensures stable breakdown characteristics across temperature and lifetime.
The diode is rated for 500 mW average power dissipation at 25 °C lead temperature, with linear derating to zero at 175 °C, and features minimal capacitance (typical <2 pF) and non-ESD-sensitive behavior per MIL-STD-750 Method 1020 - enabling use in low-noise, radiation-tolerant analog subsystems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4617US-1/TR | Same electrical specs, but in surface-mount DO-213AA package (no axial leads) | Requires SMT reflow process; unsuitable for through-hole prototyping or legacy board repair | Select when space-constrained PCB layout or automated assembly mandates SMT packaging |
| JANTXV1N4617C-1/TR | Identical electrical and mechanical specs, but qualified to higher JANTXV reliability level (extended screening) | Required for mission-critical avionics where failure modes must be statistically bounded beyond JANTX | Select when system FMEA mandates enhanced burn-in, lot acceptance testing, and radiation hardness assurance |
Compared with JANTX1N4617C-1/TR, the 1N4617US-1/TR offers identical regulation performance in a surface-mount form factor, while the JANTXV1N4617C-1/TR adds rigorous screening for extreme reliability - making the original JANTX version optimal for cost-sensitive, high-reliability programs where JANTXV-level testing is not mandated.

FAQ
What is the Zener voltage tolerance of JANTX1N4617C-1/TR?
JANTX1N4617C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2, where VZ = 2.4 V at IZT = 250 mA with C tolerance. The tighter tolerance reduces calibration overhead in precision analog designs compared to standard ±5% variants.
Is JANTX1N4617C-1/TR RoHS compliant?
No, JANTX1N4617C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with e3 suffix) are available only for commercial-grade parts, not for JAN/JANTX-qualified devices. The JANTX1N4617C-1/TR uses traditional tin-lead plating per MIL-STD-750 Method 2026, required for solderability and reliability in military applications.
What is the maximum Zener current (IZM) for JANTX1N4617C-1/TR?
The maximum Zener current (IZM) for JANTX1N4617C-1/TR is 95.0 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value corresponds to the 500 mW power rating at 2.4 V (P = V × I → 0.5 W / 2.4 V ≈ 208 mA), but IZM is limited by thermal constraints and dynamic impedance - the datasheet explicitly lists 95.0 mA as the absolute maximum dc current.
Does JANTX1N4617C-1/TR have radiation hardness?
Yes, JANTX1N4617C-1/TR is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and DO-35 hermetic glass package provide tolerance to total ionizing dose (TID) and displacement damage - a key reason it is qualified to JANTX level per MIL-PRF-19500/435 for space and nuclear applications.
What does the "TR" suffix mean in JANTX1N4617C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. Per the Mechanical and Packaging section on page 2 of T4-LDS-0245-2, TR is a standard option for this part family; JANTX1N4617C-1/TR is supplied in reels rather than bulk or ammo-pack formats, supporting high-volume manufacturing workflows.
