Product details
Overview
JANTX1N4101C-1 from Microsemi is a 500 mW, 8.2 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability applications. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance, low noise density (1 µV/√Hz), and operates across –65 °C to +175 °C junction temperature range.
For engineers reviewing the JANTX1N4101C-1 datasheet, JANTX1N4101C-1 pinout, JANTX1N4101C-1 application, or JANTX1N4101C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (250 °C/W junction-to-lead), radiation hardness, RoHS compliance status, and MIL-qualified reliability level.
Technical Context
This device functions as a precision shunt voltage regulator with cathode-banded polarity marking and operates in reverse breakdown. Its metallurgical bond construction ensures low leakage (IR ≤ 0.5 µA @ VR = 6.3 V), minimal capacitance (typ. <2 pF), and inherent radiation hardness per Microsemi MicroNote 050.
The JANTX1N4101C-1 exhibits a positive temperature coefficient of +0.070 %/°C and supports stable regulation over wide current ranges (IZK to IZM = 40 mA), with noise density falling to 1 µV/√Hz at its 8.2 V nominal Zener voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 8.2 V ±2% at IZT = 250 mA - defines precise regulation point under standard test conditions |
| Power Dissipation | 500 mW at TL = 25 °C, derated linearly to zero at 175 °C - sets maximum thermal load on lead-mounted PCB layout |
| Dynamic Impedance ZZT | 200 Ω at IZT = 250 mA - determines output voltage stability under varying load current |
| Reverse Leakage IR | ≤0.5 µA at VR = 6.3 V - ensures minimal standby power loss in high-impedance bias networks |
| Noise Density | 1 µV/√Hz at IZT = 250 mA - critical for low-noise reference applications in precision analog circuits |
| Temp. Coefficient αVZ | +0.070 %/°C - enables predictable drift compensation in temperature-stable reference designs |
| Junction Temp. Range | –65 °C to +175 °C - supports operation in aerospace, downhole, and military environments |
Pinout & Package

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 | Same 8.2 V ±2% Zener, but in DO-213AA surface-mount package; RθJA = 350 °C/W vs. 300 °C/W for JANTX1N4101C-1 | Requires reflow-compatible PCB layout; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used; verify thermal pad design for 500 mW dissipation |
| JANTXV1N4101C-1 | Identical electrical specs, but qualified to JANTXV level per MIL-PRF-19500/435 - includes burn-in, life test, and tighter lot acceptance criteria | Required for Class H (space) or Class K (strategic weapons) programs where extended reliability validation is mandated | Select when program specifications require JANTXV-level screening; adds cost and lead time but no design change |

FAQ
What is the Zener voltage tolerance of JANTX1N4101C-1?
JANTX1N4101C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its nominal 8.2 V Zener voltage falls within 8.036 V to 8.364 V at IZT = 250 mA and TA = 25 °C. The tolerance is verified per MIL-PRF-19500/435 screening requirements for JANTX-level devices.
Is JANTX1N4101C-1 RoHS compliant?
JANTX1N4101C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants, not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTX1N4101C-1 uses traditional tin-lead plating per MIL-STD-750.
What is the maximum Zener current IZM for JANTX1N4101C-1?
The maximum Zener current IZM for JANTX1N4101C-1 is 40 mA. This value is derived from its 500 mW power rating and 8.2 V nominal Zener voltage (P = V × I → I = 0.5 W / 8.2 V ≈ 61 mA), but the datasheet specifies 40 mA as the absolute maximum rated dc current to ensure long-term reliability under worst-case thermal conditions.
Does JANTX1N4101C-1 require heatsinking in typical PCB applications?
JANTX1N4101C-1 does not require external heatsinking in standard applications. Its thermal resistance junction-to-lead is 250 °C/W with 3/8″ (10 mm) lead length, and junction-to-ambient is 300 °C/W on FR4 with 4 mm² copper pads. At 500 mW dissipation and 25 °C ambient, junction temperature rises ~150 °C - remaining within its –65 °C to +175 °C rating if leads are properly terminated.
How is polarity marked on JANTX1N4101C-1?
JANTX1N4101C-1 uses a cathode band for polarity marking: the banded end is the cathode and must be held at a higher potential than the unbanded (anode) end during Zener regulation. This marking is laser-etched or painted on the glass body and conforms to JEDEC DO-35 orientation standards.
