Product details
Overview
JANTX1N4135D-1 from Microsemi is a 100 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JANTX1N4135D-1 datasheet, JANTX1N4135D-1 pinout, JANTX1N4135D-1 application, or JANTX1N4135D-1 equivalent, key selection factors include its 100 V nominal Zener voltage at 250 mA test current, 1600 Ω maximum dynamic impedance, 0.01 µA maximum reverse leakage at 76 V, +0.100 %/°C temperature coefficient, and hermetically sealed axial-leaded DO-35 construction.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band indicating polarity. Its metallurgical bond ensures stable junction characteristics under thermal cycling and radiation exposure.
Designed for operation at 250 mA Zener test current (IZT), it delivers 100 V regulation with ±1% tolerance (denoted by "D" suffix), exhibits low noise density (≤1 µV/√Hz below 6.8 V), and maintains specified performance across –65 °C to +175 °C junction temperature range.

FAQ
What is the Zener voltage tolerance of JANTX1N4135D-1?
JANTX1N4135D-1 has a ±1% Zener voltage tolerance, as indicated by the "D" suffix in its part number. This means its nominal 100 V Zener voltage is guaranteed between 99 V and 101 V when measured at 250 mA test current and 25 °C ambient. The tolerance is verified per MIL-PRF-19500/435 screening requirements for JANTX-level devices.
Is JANTX1N4135D-1 suitable for high-temperature operation?
Yes, JANTX1N4135D-1 is rated for junction temperatures from –65 °C to +175 °C and is qualified for high-reliability applications including aerospace and defense systems. Its power dissipation linearly derates from 500 mW at 25 °C to zero at 175 °C, supporting sustained operation up to 125 °C ambient with appropriate thermal design.
Does JANTX1N4135D-1 have RoHS compliance?
No, JANTX1N4135D-1 is not RoHS compliant. RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants (e.g., 1N4135-1e3), not for JANTX, JANTXV, or JANS military-qualified parts. JANTX1N4135D-1 uses traditional tin-lead plating per MIL-STD-750.
What is the maximum reverse leakage current for JANTX1N4135D-1?
The maximum reverse leakage current (IR) for JANTX1N4135D-1 is 0.01 µA at VR = 76 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports high-impedance biasing and precision reference applications where standby current must be minimized.
Can JANTX1N4135D-1 be used in surface-mount designs?
No, JANTX1N4135D-1 is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not compatible with surface-mount assembly. For SMT equivalents, consider 1N4135UR-1 in DO-213AA or 1PMT4135 in DO-216 - both share identical electrical specs but require different footprints and reflow profiles.
