Product details
Overview
JANTX1N4102-1 from Microsemi is a 500 mW, 8.7 V metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level, with 5% voltage tolerance, 200 Ω dynamic impedance at 250 mA test current, and +0.075 %/°C temperature coefficient - used for precision voltage regulation in military-grade power supplies and reference circuits.
For engineers reviewing the JANTX1N4102-1 datasheet, JANTX1N4102-1 pinout, JANTX1N4102-1 application, or JANTX1N4102-1 equivalent, key selection factors include its MIL-qualified reliability, low noise density (1 µV/√Hz), hermetic DO-35 packaging, thermal resistance of 250 °C/W (junction-to-lead), and stable regulation across -65 °C to +175 °C operating range.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 8.7 V at 250 mA test current (IZT), exhibiting a positive temperature coefficient (+0.075 %/°C) and dynamic impedance of 200 Ω. Its metallurgical bond construction ensures mechanical stability under thermal cycling and shock.
Designed for high-reliability environments, JANTX1N4102-1 meets MIL-PRF-19500/435 requirements for JANTX-level screening, including extended life testing, burn-in, and hermeticity verification. It delivers ≤0.5 µA reverse leakage at VR = 7.0 V and maintains <1 µV/√Hz noise density below 6.8 V per specification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US | Same 8.7 V rating and DO-35 package but commercial-grade (non-MIL); no JANTX screening or hermetic seal. | Lacks MIL-PRF-19500 qualification; unsuitable for aerospace or defense deployments requiring traceable reliability data. | Select only for cost-sensitive industrial prototypes where full MIL qualification is not mandated. |
| JANTXV1N4102-1 | Identical electrical specs but qualified to JANTXV level - includes additional environmental stress screening (e.g., thermal shock, mechanical shock). | Required for mission-critical subsystems where failure modes demand higher confidence in long-term parametric stability. | Choose when system-level FMEA identifies single-point failure risk and mandates enhanced screening beyond JANTX. |
Compared with JANTX1N4102-1, 1N4102US offers lower cost but no MIL qualification or hermeticity, while JANTXV1N4102-1 adds thermal/mechanical stress validation - enabling trade-offs between reliability assurance, lifecycle cost, and program certification requirements.

FAQ
What is the Zener voltage tolerance for JANTX1N4102-1?
JANTX1N4102-1 has a nominal Zener voltage of 8.7 V with a standard ±5% tolerance, consistent with JEDEC registration and MIL-PRF-19500/435 requirements for JANTX-level devices. This tolerance applies under specified test conditions: 250 mA Zener test current and thermal equilibrium at 25 °C ambient. The JANTX1N4102-1 datasheet confirms this value in Table 1 on Page 3.
Is JANTX1N4102-1 RoHS compliant?
No, JANTX1N4102-1 is not RoHS compliant. Per the T4-LDS-0245-2 datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade variants (e.g., 1N4102-1e3), not for MIL-qualified JANTX, JANTXV, or JANS levels. The JANTX1N4102-1 uses tin-lead plating per MIL-STD-750 and retains lead content required for high-reliability solder joint integrity.
What is the maximum junction temperature for JANTX1N4102-1?
The maximum junction and storage temperature for JANTX1N4102-1 is +175 °C, with a minimum of -65 °C. This rating is specified in the Maximum Ratings table on Page 1 of the official datasheet. Derating begins linearly at +50 °C lead temperature, reaching zero power dissipation at +175 °C - a critical constraint for thermal design in sealed enclosures or high-ambient environments using JANTX1N4102-1.
Does JANTX1N4102-1 have radiation hardness specifications?
Yes, JANTX1N4102-1 exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. While not individually tested to MIL-STD-883 methods for TID or SEE, its metallurgically bonded glass construction and DO-35 hermetic package provide proven resilience against total ionizing dose and displacement damage - making it suitable for low-earth orbit and avionics applications where JANTX1N4102-1 is deployed without supplemental shielding.
What is the thermal resistance junction-to-lead for JANTX1N4102-1?
The thermal resistance junction-to-lead (RθJL) for JANTX1N4102-1 is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the package body. This value is critical for calculating junction temperature rise under load and appears in the Maximum Ratings table on Page 1 of the T4-LDS-0245-2 datasheet. It reflects the device's ability to conduct heat through leads to external heatsinking - a key parameter when designing for reliability in JANTX1N4102-1-based regulators.
