Product details
Overview
JANTX1N4113D-1/TR from Microsemi is a 19.0 V, 1% tolerance, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4113D-1/TR datasheet, JANTX1N4113D-1/TR pinout, JANTX1N4113D-1/TR application, or JANTX1N4113D-1/TR equivalent, key selection criteria include its 19.0 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.05 µA maximum reverse leakage at 14.5 V, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with metallurgically bonded construction ensuring stable breakdown characteristics under thermal and radiation stress. Its 1% voltage tolerance and low noise density (1 µV/√Hz typical at lower voltages) support reference-grade stability in analog signal chains and regulated bias networks.
The JANTX1N4113D-1/TR exhibits a positive temperature coefficient of +0.090 %/°C and is rated for 40 mA maximum Zener current at 25 °C ambient, with linear derating to zero power at 175 °C junction temperature. It is non-sensitive to ESD per MIL-STD-750 Method 1020 and hermetically sealed in glass.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4113US-1 | Same 19.0 V/1% spec but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; eliminates lead inductance in RF bias networks | Select when board space is constrained and reflow compatibility is required |

FAQ
What is the Zener voltage and tolerance of JANTX1N4113D-1/TR?
JANTX1N4113D-1/TR has a nominal Zener voltage of 19.0 V at 250 mA test current with ±1% tolerance. This value is verified per MIL-PRF-19500/435 screening and applies across the full -65 °C to +175 °C junction temperature range. The "D" in the part number explicitly denotes the 1% tolerance grade per Microsemi's nomenclature.
Is JANTX1N4113D-1/TR RoHS compliant?
No, JANTX1N4113D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTX1N4113D-1/TR. The lead finish remains traditional tin-lead per MIL-STD-750.
What is the maximum Zener current rating for JANTX1N4113D-1/TR?
JANTX1N4113D-1/TR is rated for a maximum Zener current (IZM) of 40 mA at 25 °C ambient temperature. This corresponds to its 500 mW power rating at VZ = 19.0 V. Current must be linearly derated above 50 °C lead temperature, reaching zero at 175 °C junction temperature per Figure 2 in the datasheet.
Does JANTX1N4113D-1/TR have radiation hardness specifications?
Yes, JANTX1N4113D-1/TR is inherently radiation hard as described in Microsemi MicroNote 050. Its metallurgically bonded glass construction and hermetic sealing provide resistance to total ionizing dose (TID), making it suitable for low-earth orbit satellite applications where cumulative radiation exposure occurs.
What does the "TR" suffix indicate in JANTX1N4113D-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard. JANTX1N4113D-1/TR is supplied in industry-standard carrier tape with 2,000 units per reel, enabling automated pick-and-place assembly. The "TR" suffix does not affect electrical or reliability specifications-it is purely a packaging designation.
