Product details
Overview
JANTX1N4101C-1/TR from Microsemi is a 500 mW, 8.2 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTX reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 250 mA test current, and 200 Ω dynamic impedance - used for precision voltage reference and regulation in military-grade power supply circuits.
For engineers reviewing the JANTX1N4101C-1/TR datasheet, JANTX1N4101C-1/TR pinout, JANTX1N4101C-1/TR application, or JANTX1N4101C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), hermetic glass packaging, MIL-qualified thermal stability (–65 °C to +175 °C), and metallurgically bonded junction integrity.
Technical Context
This device operates in reverse-biased breakdown mode to maintain stable 8.2 V output across wide current (5.7 mA to 40 mA) and temperature (–65 °C to +175 °C) ranges. Its metallurgical bond ensures high-reliability operation under thermal cycling and radiation exposure.
The DO-35 package provides hermetic sealing and axial-leaded mounting compatible with through-hole PCB assembly. Zener impedance of 200 Ω at 250 mA test current enables predictable regulation under load transients, while noise density of 1 µV/√Hz supports low-noise analog reference applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US-1/TR | Same 8.2 V ±2%, but in surface-mount DO-213AA package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or legacy board repair | Select when space-constrained PCB layout demands SMT compatibility and automated assembly |
| JANTXV1N4101C-1/TR | Identical electrical specs but qualified to higher JANTXV reliability level per MIL-PRF-19500/435 | Required for mission-critical avionics where burn-in and lot acceptance testing exceed JANTX requirements | Select when program specification mandates JANTXV-level screening and extended test documentation |
Compared with JANTX1N4101C-1/TR, the 1N4101US-1/TR offers identical regulation performance in a smaller footprint but sacrifices axial-leaded serviceability, while JANTXV1N4101C-1/TR delivers enhanced reliability assurance at higher cost and longer lead time - both require explicit validation for drop-in use in existing JANTX-qualified designs.

FAQ
What is the Zener voltage and tolerance of JANTX1N4101C-1/TR?
JANTX1N4101C-1/TR has a nominal Zener voltage of 8.2 V with a ±2% tolerance, measured at 250 mA test current and 25 °C ambient. This tolerance is denoted by the "C" suffix in the part number and is verified per MIL-PRF-19500/435 screening. The JANTX1N4101C-1/TR maintains this accuracy across its rated junction temperature range of –65 °C to +175 °C.
Is JANTX1N4101C-1/TR RoHS compliant?
No, JANTX1N4101C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4101C-1e3); JANTX-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability in military applications. The JANTX1N4101C-1/TR uses standard tin-lead termination.
What is the maximum Zener current IZM for JANTX1N4101C-1/TR?
The maximum Zener current IZM for JANTX1N4101C-1/TR is 40 mA, derived from its 500 mW power rating and 8.2 V Zener voltage (P = V × I → I = 0.5 W / 8.2 V ≈ 61 mA), but limited by thermal resistance and derating curves to 40 mA at TL = 50 °C. Full 500 mW dissipation is only valid at 25 °C lead temperature, with linear derating to zero at 175 °C.
How does the noise performance of JANTX1N4101C-1/TR compare to lower-voltage Zeners?
JANTX1N4101C-1/TR exhibits 1 µV/√Hz noise density at 250 mA test current - consistent with the "≤1 µV/√Hz at lower voltages" trend documented for the 1N4099–1N4135 family. This is significantly lower than higher-voltage Zeners (e.g., 1N4135-1: 4.2 µV/√Hz) and makes JANTX1N4101C-1/TR especially suitable for low-noise analog references where spectral purity matters.
What packaging and marking details apply to JANTX1N4101C-1/TR?
JANTX1N4101C-1/TR is supplied in DO-35 (DO-204AH) hermetically sealed glass axial-leaded package with cathode indicated by a visible band. It is marked with the full part number "JANTX1N4101C-1" and packaged in tape-and-reel per EIA-296 (denoted by "TR" suffix). Lead finish is tin-lead per MIL-STD-750, and weight is approximately 0.2 g.
