Product details
Overview
JANTX1N4102D-1/TR from Microsemi is a 1% tolerance, 8.7 V, 500 mW metallurgically bonded glass Zener diode in DO-35 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 JANTX1N4102D-1/TR datasheet, JANTX1N4102D-1/TR pinout, JANTX1N4102D-1/TR application, or JANTX1N4102D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (200 Ω at 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.075 %/°C), and hermetic DO-35 packaging for stable operation across -65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 8.7 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and minimal capacitance (typical 44 pF). Its metallurgical bond construction ensures mechanical stability under thermal cycling and shock.
The JANTX qualification confirms compliance with MIL-PRF-19500/435 for screening, testing, and traceability-supporting use in radiation-hardened and mission-critical systems where leakage current ≤0.5 µA at 7.0 V reverse bias and junction temperature range (-65 °C to +175 °C) are essential.
Key Specifications

|---|---|
| Zener Voltage VZ | 8.7 V ±1% at 250 mA - enables precise reference generation in analog power monitoring circuits |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - supports stable operation in conduction-cooled avionics enclosures |
| Dynamic Impedance ZZT | 200 Ω at 250 mA - maintains tight regulation under load transients in feedback loops |
| Noise Density | 1 µV/√Hz - critical for low-noise voltage references in precision ADC front-ends |

Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band; banded end is anode when used in forward bias, but functions as cathode (positive terminal) during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Zener cathode connection | Connected to regulated output node; must be held at higher potential than cathode for breakdown conduction |
| Cathode (unbanded end) | Zener anode connection | Connected to circuit ground or lower-potential rail; establishes reference return path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US-1 | Same electrical specs, but in surface-mount DO-213AA package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair | Select when board space is constrained and reflow compatibility is mandatory |
| JANTXV1N4102D-1 | Identical specs plus extended JANTXV screening (including 100% life test and enhanced radiation hardness) | Required for launch-critical subsystems where single-event burnout (SEB) immunity is mandated | Select when operating in LEO or GEO orbits with proton fluence >1×10¹⁰ p/cm² |
Compared with JANTX1N4102D-1/TR, the 1N4102US-1 offers identical regulation performance in a compact SMT form factor but lacks axial mounting flexibility, while JANTXV1N4102D-1 adds radiation hardening and lifetime validation at higher cost-making it suitable only for space-grade deployments where JANTX-level reliability is insufficient.

FAQ
What does the "D" suffix indicate in JANTX1N4102D-1/TR?
The "D" suffix in JANTX1N4102D-1/TR specifies ±1% Zener voltage tolerance, per JEDEC nomenclature. This tighter tolerance enables higher-accuracy voltage references in JANTX-qualified applications compared to standard 5% (blank) or 2% (C) variants. JANTX1N4102D-1/TR delivers 8.7 V ±0.087 V at 250 mA, verified during MIL-PRF-19500/435 screening.
Is JANTX1N4102D-1/TR RoHS compliant?
No, JANTX1N4102D-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 JANTX, JANTXV, or JANS qualified devices. JANTX1N4102D-1/TR uses traditional tin-lead plating to ensure solderability and reliability under MIL-STD-750 testing.
What is the maximum Zener current IZM for JANTX1N4102D-1/TR?
The maximum Zener current IZM for JANTX1N4102D-1/TR is 6.7 mA at 25 °C ambient, derived from its 500 mW power rating and 8.7 V nominal Zener voltage (IZM = 500 mW / 8.7 V ≈ 57.5 mA), but limited by thermal resistance and derating curves to 6.7 mA at full rated power. Actual safe operating current depends on PCB layout and lead length per Figure 2 in T4-LDS-0245-2.
How is polarity marked on JANTX1N4102D-1/TR?
JANTX1N4102D-1/TR uses a cathode band marking: the banded end is the cathode terminal and must be connected to the higher-potential node during Zener regulation. When used as a Zener diode, the banded end is positive relative to the unbanded (anode) end. This marking follows JEDEC DO-35 standards and is laser-etched or inked directly on the glass body.
Does JANTX1N4102D-1/TR require derating above 25 °C?
Yes, JANTX1N4102D-1/TR requires linear derating of its 500 mW power dissipation starting at 25 °C ambient, reaching zero at 175 °C junction temperature. Derating slope is -3.33 mW/°C (500 mW ÷ 150 °C), per Figure 2 in T4-LDS-0245-2. At 70 °C ambient, maximum allowable power drops to ~333 mW, directly impacting usable Zener current in JANTX1N4102D-1/TR designs.
