Product details
Overview
JANTX1N4615-1/TR from Microsemi is a 2.0 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435, with 5% voltage tolerance, 250 mA Zener test current, and 1250 Ω dynamic impedance - used for precision voltage reference and regulation in military-grade power supply monitoring circuits.
For engineers reviewing the JANTX1N4615-1/TR datasheet, JANTX1N4615-1/TR pinout, JANTX1N4615-1/TR application, or JANTX1N4615-1/TR equivalent, key selection criteria include Zener voltage stability over temperature (αVZ = −0.075 %/°C), low noise density (1 µV/√Hz), hermetic DO-35 packaging, and MIL-qualified reliability for high-reliability analog subsystems.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 2.0 V at 250 mA test current (IZT), exhibiting a dynamic impedance of 1250 Ω and a temperature coefficient of −0.075 %/°C - indicating stable low-voltage regulation across industrial and military temperature ranges (−65 °C to +175 °C).
Its metallurgical bond construction ensures low leakage (IR ≤ 2.5 µA at VR = 1.0 V), minimal capacitance (typical <2 pF), and inherent radiation hardness per Microsemi MicroNote 050 - making it suitable for space-qualified and high-reliability analog reference designs where long-term parametric drift must be minimized.
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 electrical specs but in surface-mount DO-213AA package; no axial leads | Used where board space is constrained and reflow assembly is required | Select when transitioning from through-hole to SMT production without changing circuit topology |
| JAN1N4615-1 | Identical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTX) | Suitable for cost-sensitive military programs where full JANTX screening is not mandated | Choose when budget constraints exist but MIL-PRF-19500 compliance remains mandatory |
Compared with JANTX1N4615-1/TR, the 1N4615US-1 offers identical regulation performance in a space-saving SMT form factor, while JAN1N4615-1 delivers the same core functionality at lower qualification cost - enabling trade-offs between reliability assurance, layout flexibility, and procurement budget.

FAQ
What is the Zener voltage and tolerance of JANTX1N4615-1/TR?
JANTX1N4615-1/TR has a nominal Zener voltage of 2.0 V at 250 mA test current (IZT), with a standard tolerance of ±5% per JEDEC registration. This tolerance reflects manufacturing variation under MIL-PRF-19500/435 JANTX screening, and the actual measured VZ falls within 1.90 V to 2.10 V at 25 °C ambient and thermal equilibrium.
Is JANTX1N4615-1/TR RoHS compliant?
No, JANTX1N4615-1/TR is not RoHS compliant. The "TR" suffix denotes tape-and-reel packaging, while RoHS compliance (designated by "e3") is available only on commercial-grade versions of this family - JANTX-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability in high-reliability military assemblies.
What is the maximum power dissipation and derating behavior of JANTX1N4615-1/TR?
JANTX1N4615-1/TR is rated for 500 mW average power dissipation at case temperature (TC) = 25 °C. Power must be linearly derated starting at TC = 50 °C, reaching zero at TC = 175 °C. On a typical FR4 PCB with 4 mm² copper pads, ambient-based derating begins at TA = 25 °C, following the same linear slope per Figure 2 in the T4-LDS-0245-2 datasheet.
Does JANTX1N4615-1/TR have radiation hardness certification?
Yes, JANTX1N4615-1/TR exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and DO-35 hermetic seal provide resistance to total ionizing dose (TID) effects, making it suitable for low-earth orbit and terrestrial nuclear environments without additional shielding or qualification testing.
What does the "JANTX" prefix signify for JANTX1N4615-1/TR?
The "JANTX" prefix indicates that JANTX1N4615-1/TR is screened and tested to the JANTX level per MIL-PRF-19500/435 - including extended temperature cycling, burn-in, and parametric verification beyond commercial standards. This qualification ensures suitability for high-reliability military and aerospace applications where failure risk must be minimized.
