Product details
Overview
JANTX1N4615C-1 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 ±2% Zener voltage tolerance, 1250 Ω dynamic impedance at 250 mA test current, and 1.0 µA maximum reverse leakage at 2.0 V. It serves as a precision voltage reference in military-grade power regulation and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4615C-1 datasheet, JANTX1N4615C-1 pinout, JANTX1N4615C-1 application, or JANTX1N4615C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), MIL-spec reliability qualification, thermal resistance (250 °C/W junction-to-lead), and axial-leaded DO-35 mechanical compatibility for through-hole high-reliability PCBs.
Technical Context
This device operates in reverse breakdown mode with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgical bond construction ensures stable Zener voltage over temperature and radiation-hardened performance per Microsemi MicroNote 050.
The 2.0 V nominal Zener voltage exhibits a temperature coefficient of –0.075 %/°C, enabling predictable drift compensation in analog references. Maximum rated average power dissipation is 500 mW at 25 °C, derating linearly to zero at 175 °C ambient with defined thermal resistance junction-to-lead (250 °C/W) and junction-to-ambient (300 °C/W).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4615US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used |
| JAN1N4615C-1 | Identical electrical and mechanical specs; differs only in reliability screening level (JAN vs JANTX) | JAN lacks extended life test and lot traceability required for flight-critical subsystems | Select JANTX1N4615C-1 when full MIL-PRF-19500/435 compliance documentation is mandated |
Compared with 1N4615US-1 and JAN1N4615C-1, JANTX1N4615C-1 uniquely combines DO-35 axial mounting, JANTX-level screening, and ±2% tolerance-making it the only choice for through-hole, high-reliability, low-voltage reference designs requiring full military qualification.

FAQ
What is the Zener voltage tolerance of JANTX1N4615C-1?
JANTX1N4615C-1 has a nominal Zener voltage of 2.0 V with a tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed under standard test conditions (25 °C, IZT = 250 mA) and applies across the full JANTX reliability screening level, including temperature cycling and life testing.
Is JANTX1N4615C-1 suitable for surface-mount assembly?
No, JANTX1N4615C-1 uses the axial-leaded DO-35 (DO-204AH) glass package and is intended for through-hole mounting. For surface-mount equivalents, consider the 1N4615US-1 in DO-213AA package-but note that it lacks JANTX qualification and requires different reflow profiles and board layout.
What is the maximum reverse leakage current for JANTX1N4615C-1?
The maximum reverse leakage current (IR) for JANTX1N4615C-1 is 1.0 µA at VR = 2.0 V and 25 °C, as specified in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet. This low leakage supports high-impedance analog sensing and battery-powered standby modes.
Does JANTX1N4615C-1 meet RoHS requirements?
JANTX1N4615C-1 is not RoHS compliant. Per Microsemi's documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTX1N4615C-1 uses traditional tin-lead plating per MIL-STD-750.
How does the temperature coefficient affect JANTX1N4615C-1 performance?
JANTX1N4615C-1 has a temperature coefficient (αVZ) of –0.075 %/°C, meaning its Zener voltage decreases by approximately 1.5 mV per °C rise above 25 °C. This predictable negative drift allows system designers to compensate for thermal effects in precision reference circuits across –65 to +175 °C operating ranges.
