Product details
Overview
JANTX1N4615D-1/TR from Microsemi is a 2.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in military and aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4615D-1/TR datasheet, JANTX1N4615D-1/TR pinout, JANTX1N4615D-1/TR application, or JANTX1N4615D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), low noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and MIL-spec qualification level - all critical for precision reference and radiation-hardened designs.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 2.0 V at 250 mA test current, exhibiting a temperature coefficient of −0.075 %/°C and dynamic impedance of 1250 Ω at IZT. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and mechanical stress.
Rated for 500 mW average power dissipation at 25 °C lead temperature, it linearly derates to zero at 175 °C and supports operation across −65 °C to +175 °C junction temperature range. Reverse leakage is limited to ≤2.5 µA at 1.0 V, enabling low-power biasing in precision analog subsystems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4615US-1 | Same 2.0 V/1% Zener spec but in surface-mount DO-213AA package; no axial leads | Used where board space is constrained and reflow assembly required; lacks axial mounting flexibility | Select when automated SMT placement and smaller footprint outweigh manual soldering needs |
| JANTXV1N4615D-1 | Identical electrical specs but qualified to higher JANTXV level per MIL-PRF-19500/435 with extended screening | Required for mission-critical systems demanding enhanced burn-in, life-test, and radiation assurance | Choose when program requirements mandate JANTXV-level reliability documentation and test reports |
Compared with JANTX1N4615D-1/TR, the 1N4615US-1 offers packaging flexibility at the cost of mechanical mounting adaptability, while JANTXV1N4615D-1 delivers identical regulation performance with stricter process controls - making the original optimal for JANTX-compliant programs balancing cost and proven reliability.

FAQ
What is the Zener voltage tolerance of JANTX1N4615D-1/TR?
JANTX1N4615D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per MIL-PRF-19500/435 nomenclature. This is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where VZ = 2.0 V at IZT = 250 mA with 1% tolerance. The tighter tolerance reduces calibration overhead in precision analog circuits compared to standard 5% variants like JANTX1N4615-1.
Is JANTX1N4615D-1/TR RoHS compliant?
No, JANTX1N4615D-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS qualified devices. The JANTX1N4615D-1/TR uses tin-lead plating per MIL-STD-750 method 2026 and retains legacy Pb content required for high-reliability solder joint integrity in military applications.
What is the maximum Zener current IZM for JANTX1N4615D-1/TR?
The maximum Zener current IZM for JANTX1N4615D-1/TR is 110.0 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This value corresponds to the rated 500 mW power dissipation at 2.0 V (P = V × I → 0.5 W ÷ 2.0 V = 250 mA theoretical, but derated due to thermal limits and impedance losses). The 110.0 mA reflects safe continuous DC operation under defined thermal conditions.
Does JANTX1N4615D-1/TR have radiation hardness certification?
Yes, JANTX1N4615D-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic package provide natural resistance to total ionizing dose (TID) and single-event effects (SEE), making it suitable for space and nuclear applications without additional shielding or qualification testing beyond standard JANTX screening.
What does the "TR" suffix indicate in JANTX1N4615D-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. As noted on page 2 of T4-LDS-0245-2 Rev. 1, this option is available for JANTX1N4615D-1/TR with factory consultation on quantities. The TR format preserves full JANTX qualification and does not affect electrical or reliability specifications - it is purely a logistics and handling enhancement.
