Product details
Overview
JAN1N4111-1/TR from Microsemi is a 500 mW, 17.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JAN level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 100 Ω dynamic impedance, low 0.05 µA reverse leakage at 13.0 V, and +0.090 %/°C temperature coefficient - used in precision reference and power supply feedback circuits for aerospace-grade instrumentation.
For engineers reviewing the JAN1N4111-1/TR datasheet, JAN1N4111-1/TR pinout, JAN1N4111-1/TR application, or JAN1N4111-1/TR equivalent, key selection criteria include its MIL-qualified reliability grade, 17.0 V nominal Zener voltage with 5% tolerance, DO-35 mechanical robustness, thermal resistance of 250 °C/W (junction-to-lead), and noise density of 1 µV/√Hz - all critical for high-reliability analog reference design.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with cathode indicated by band and intended for banded-end-positive polarity. Its metallurgical bond construction ensures low noise and radiation hardness per MicroNote 050, while the hermetically sealed DO-35 glass package maintains stability across -65 °C to +175 °C junction temperature range.
It exhibits a linear power derating curve from 500 mW at 25 °C ambient to zero at 175 °C, with maximum Zener current IZM of 13.0 mA at rated dissipation. Dynamic impedance ZZT is measured at 10% rms AC modulation superimposed on 250 mA DC test current, yielding 100 Ω typical value at 17.0 V.

FAQ
What is the Zener voltage tolerance of JAN1N4111-1/TR?
JAN1N4111-1/TR has a nominal Zener voltage of 17.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with 250 mA test current.
Is JAN1N4111-1/TR RoHS compliant?
No, JAN1N4111-1/TR is not RoHS compliant. Per the nomenclature guide on page 2, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. The JAN prefix indicates military qualification with tin-lead plating, and no RoHS-compliant variant exists for this specific JAN-level part number.
What does the "TR" suffix mean in JAN1N4111-1/TR?
The "TR" suffix in JAN1N4111-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This packaging option is explicitly noted in the Mechanical and Packaging section on page 2, and requires consultation with the factory for minimum order quantities and reel configuration details.
What is the maximum Zener current IZM for JAN1N4111-1/TR?
The maximum Zener current IZM for JAN1N4111-1/TR is 13.0 mA, as specified in the Electrical Characteristics table on page 3. This value corresponds to the current at which the device dissipates its rated 500 mW at 17.0 V, assuming ideal thermal conditions and proper lead heat sinking per the RθJL = 250 °C/W specification.
How is polarity marked on JAN1N4111-1/TR?
Polarity on JAN1N4111-1/TR is marked by a visible cathode band on the glass body; the banded end is the cathode and must be held positive relative to the anode for Zener regulation. This marking convention is documented in the Mechanical and Packaging section on page 2 and aligns with JEDEC DO-35 standard orientation.
