Product details
Overview
JANTX1N4135-1/TR from Microsemi is a 100 V, ±5% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation. It delivers 250 mA Zener test current, 1600 Ω dynamic impedance at IZT, and 3.8 mA maximum Zener current at rated power, used in precision reference and overvoltage protection circuits in aerospace power supplies.
For engineers reviewing the JANTX1N4135-1/TR datasheet, JANTX1N4135-1/TR pinout, JANTX1N4135-1/TR application, or JANTX1N4135-1/TR equivalent, key selection criteria include its 100 V nominal Zener voltage, MIL-qualified JANTX reliability grade, DO-35 hermetic glass package, 40 µV/√Hz noise density at ≥6.8 V, and thermal resistance of 250 °C/W junction-to-lead.
Technical Context
This device operates as a reverse-biased voltage reference with a specified Zener voltage of 100 V at 250 mA test current, exhibiting +0.100 %/°C temperature coefficient and 1600 Ω dynamic impedance at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The DO-35 glass package provides hermetic sealing, enabling operation from –65 °C to +175 °C junction temperature. Power dissipation is linearly derated from 500 mW at 25 °C ambient to zero at 175 °C, with 250 °C/W junction-to-lead thermal resistance measured at 10 mm lead length.

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 electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping | Select when automated SMT production and space-constrained layouts are prioritized over manual repairability |
| JANS1N4135-1 | Identical electrical and mechanical specs but qualified to JANS (highest MIL-PRF-19500 level) with full lot traceability | Required for nuclear-hardened or mission-critical flight hardware where JANTX screening is insufficient | Select only when program specifications mandate JANS-level radiation hardness and process documentation |
Compared with JANTX1N4135-1/TR, the 1N4135US-1 offers identical regulation performance in a smaller footprint but eliminates axial-lead serviceability, while JANS1N4135-1 adds radiation tolerance and full lot traceability at higher cost and longer lead time-neither is pin-compatible due to differing packages or screening scope.

FAQ
What is the Zener voltage tolerance of JANTX1N4135-1/TR?
JANTX1N4135-1/TR has a nominal Zener voltage of 100 V with a ±5% tolerance, meaning the actual breakdown voltage falls between 95 V and 105 V when measured at 250 mA test current and 25 °C ambient. This tolerance is standard for the JEDEC-registered 1N4099-1 to 1N4135-1 series unless otherwise marked with C (±2%) or D (±1%) suffixes.
Is JANTX1N4135-1/TR RoHS compliant?
No, JANTX1N4135-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions of this family (e.g., 1N4135-1e3), not to MIL-qualified JANTX-level parts. JANTX1N4135-1/TR uses traditional tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability in high-reliability applications.
What is the maximum power dissipation of JANTX1N4135-1/TR at 100 °C ambient temperature?
At 100 °C ambient temperature, JANTX1N4135-1/TR's maximum power dissipation is 333 mW. This is derived from linear derating starting at 500 mW at 25 °C, decreasing by 4.17 mW/°C until reaching zero at 175 °C. The derating slope is confirmed in Figure 2 of the T4-LDS-0245-2 datasheet.
Does JANTX1N4135-1/TR have a specified noise density value?
Yes, JANTX1N4135-1/TR has a maximum noise density of 40 µV/√Hz, consistent with all devices in the 1N4099-1 through 1N4135-1 series rated at 6.8 V and above. This value is measured using a 1 kHz–3 kHz bandpass filter at 25 °C and 250 mA Zener test current, as defined in Figure 1 of the datasheet.
What does the "TR" suffix indicate in JANTX1N4135-1/TR?
The "TR" suffix in JANTX1N4135-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. It does not affect electrical or reliability specifications-JANTX1N4135-1/TR shares identical Zener voltage, power rating, MIL-qualification, and thermal characteristics as the bulk-packaged JANTX1N4135-1.
