Product details
Overview
JANTX1N4135C-1 from Microsemi is a 100 V, 2% 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.
For engineers reviewing the JANTX1N4135C-1 datasheet, JANTX1N4135C-1 pinout, JANTX1N4135C-1 application, or JANTX1N4135C-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, noise density, dynamic impedance, and military qualification details critical for precision reference and ruggedized bias design.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias connection where the banded end is positive relative to the anode. Its metallurgical bond construction ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
It delivers 100 V nominal Zener voltage at 250 mA test current (IZT), with 1600 Ω maximum dynamic impedance (ZZT) and +0.100 %/°C temperature coefficient - enabling predictable drift compensation in high-stability analog circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4135US-1 | Same 100 V, 2% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; lacks JANTX screening | Select when board space is constrained and MIL qualification is not required |
| JANS1N4135C-1 | Identical electrical specs and DO-35 package; qualified to higher JANS reliability level per MIL-PRF-19500/435 | Approved for Class K (spaceflight) and Class H (high-reliability) programs; longer test duration and tighter lot controls | Select when mission-critical radiation tolerance and zero-defect screening are mandated |
Compared with JANTX1N4135C-1, the JANS1N4135C-1 adds full space-level screening and radiation assurance at higher cost and longer lead time, while the 1N4135US-1 trades military qualification for surface-mount compatibility - making JANTX1N4135C-1 the optimal balance of reliability, legacy through-hole fit, and cost for tactical avionics upgrades.

FAQ
What is the Zener voltage tolerance of JANTX1N4135C-1?
JANTX1N4135C-1 has a nominal Zener voltage of 100 V with a ±2% tolerance, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current (IZT) under thermal equilibrium at 25 °C ambient, and applies across the full qualified operating temperature range when derated per MIL-PRF-19500/435 requirements.
Is JANTX1N4135C-1 RoHS compliant?
No, JANTX1N4135C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only on commercial-grade parts, not on JAN, JANTX, JANTXV, or JANS qualified devices like JANTX1N4135C-1. The JANTX1N4135C-1 uses traditional tin-lead plating per MIL-STD-750 method 2026.
What is the maximum Zener current (IZM) for JANTX1N4135C-1?
The maximum Zener current (IZM) for JANTX1N4135C-1 is 76.0 mA, derived from its 500 mW power rating and 100 V nominal Zener voltage (P = V × I). This value is specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 and assumes operation at 25 °C lead temperature with appropriate derating above 50 °C.
Does JANTX1N4135C-1 have a specified noise density?
Yes, JANTX1N4135C-1 has a maximum noise density of 1 μV/√Hz, consistent with the 100 V group in the 1N4132–1N4135 series. This value is measured using a 1 kHz–3 kHz bandpass filter at 25 °C ambient and 250 mA Zener test current, as defined in Figure 1 and Note 3 of the datasheet.
What packaging options exist for JANTX1N4135C-1?
JANTX1N4135C-1 is supplied exclusively in the axial-leaded DO-35 (DO-204AH) hermetically sealed glass package. Alternate packages such as DO-213AA (surface mount) or DO-216 (tabbed SMT) are available only for commercial variants (e.g., 1N4135UR-1), not for the JANTX-qualified JANTX1N4135C-1.
