Product details
Overview
JANS1N4115D-1/TR from Microsemi is a 22 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability space and defense applications. It delivers stable voltage regulation at 250 mA test current with 150 Ω dynamic impedance, 0.01 µA reverse leakage at 17.6 V, and +0.090 %/°C temperature coefficient.
For engineers reviewing the JANS1N4115D-1/TR datasheet, JANS1N4115D-1/TR pinout, JANS1N4115D-1/TR application, or JANS1N4115D-1/TR equivalent, key selection criteria include Zener voltage tolerance (1%), radiation hardness, hermetic glass packaging, MIL-qualified reliability level, and low-noise performance in precision reference circuits.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with cathode indicated by band and required to be held positive relative to anode for regulation. Its metallurgical bond construction ensures mechanical stability under thermal cycling and shock, critical for aerospace deployment.
It exhibits a +0.090 %/°C temperature coefficient above 20 V, enabling predictable drift compensation in closed-loop systems. Noise density is specified at 1 µV/√Hz (typical), verified at 25 °C with 250 mA Zener test current and 1–3 kHz measurement bandwidth.

FAQ
What is the Zener voltage tolerance of JANS1N4115D-1/TR?
JANS1N4115D-1/TR has a nominal Zener voltage of 22.0 V with a tight ±1% tolerance, as indicated by the "D" suffix in its nomenclature. This tolerance is guaranteed at 250 mA test current and 25 °C ambient, and is maintained across the full qualified temperature range of −65 to +175 °C due to JANS-level screening and metallurgical bond construction.
Is JANS1N4115D-1/TR radiation hardened?
Yes, JANS1N4115D-1/TR is inherently radiation hard per Microsemi MicroNote 050 and qualified to JANS level under MIL-PRF-19500/435. It is validated for total ionizing dose (TID) resilience up to 100 krad(Si), making it suitable for low-earth orbit and deep-space applications where single-event effects and parametric degradation must be minimized.
What package type does JANS1N4115D-1/TR use?
JANS1N4115D-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Its dimensions comply with JEDEC standards: body diameter 1.42–2.29 mm, overall length 25.4–38.1 mm, and cathode identified by a visible band. The "TR" suffix confirms tape-and-reel packaging per EIA-296.
What is the maximum reverse leakage current for JANS1N4115D-1/TR?
The maximum reverse leakage current (IR) for JANS1N4115D-1/TR is 0.01 µA at 17.6 V (80% of nominal Zener voltage), measured at 25 °C. This ultra-low leakage supports high-impedance reference nodes and extends battery life in always-on instrumentation circuits where standby current must remain below 100 nA.
Does JANS1N4115D-1/TR require derating at elevated temperatures?
Yes, JANS1N4115D-1/TR requires linear derating of its 500 mW power dissipation starting at 50 °C case temperature, reaching zero at 175 °C. On a typical FR4 board with 4 mm² copper pads, derating begins at 25 °C ambient. Full derating curves and thermal resistance values (RθJA = 300 °C/W, RθJL = 250 °C/W) are provided in the official Microsemi T4-LDS-0245-2 datasheet.
