Product details
Overview
JANTX1N4615C-1/TR from Microsemi is a 2.0 V, 2% tolerance, 500 mW axial-leaded Zener diode in DO-35 glass package, qualified to JANTX reliability level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 1250 Ω dynamic impedance and −0.075 %/°C temperature coefficient, used in precision reference and biasing circuits for military avionics power supplies.
For engineers reviewing the JANTX1N4615C-1/TR datasheet, JANTX1N4615C-1/TR pinout, JANTX1N4615C-1/TR application, or JANTX1N4615C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), junction temperature range (−65 °C to +175 °C), noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and MIL-qualified reliability level - all critical for high-reliability analog reference design.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction ensuring low leakage and radiation hardness. Its 2.0 V nominal Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance measured at 10% AC modulation superimposed on IZT.
The −0.075 %/°C temperature coefficient enables predictable drift over −65 °C to +175 °C operating range, and its 1 µV/√Hz noise density at IZT supports low-noise analog signal conditioning in regulated power rails and sensor excitation circuits.

FAQ
What is the Zener voltage tolerance of JANTX1N4615C-1/TR?
JANTX1N4615C-1/TR has a nominal Zener voltage of 2.0 V with a guaranteed tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified under standard test conditions at 25 °C with 250 mA Zener test current (IZT), and applies across the full qualified operating temperature range.
Is JANTX1N4615C-1/TR RoHS compliant?
No, JANTX1N4615C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTX-level devices like JANTX1N4615C-1/TR retain tin-lead plating to meet MIL-STD-750 solderability requirements and maintain legacy qualification integrity.
What does the "TR" suffix mean in JANTX1N4615C-1/TR?
The "TR" suffix in JANTX1N4615C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. This packaging option is distinct from bulk or ammo-pack formats and ensures consistent orientation and mechanical protection during SMT assembly of JANTX1N4615C-1/TR.
What is the maximum Zener current IZM for JANTX1N4615C-1/TR?
The maximum Zener current IZM for JANTX1N4615C-1/TR is 110.0 mA, derived from its 500 mW power rating and 2.0 V Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25 °C lead temperature and linearly derates above 50 °C per the published power derating curve in the datasheet.
How is polarity marked on JANTX1N4615C-1/TR?
JANTX1N4615C-1/TR uses a cathode band marking on the glass body to indicate polarity: the banded end is the cathode and must be held positive relative to the anode to achieve Zener regulation. This marking complies with JEDEC DO-35 standards and is visible under standard visual inspection during board assembly.
