Product details
Overview
JANS1N4135D-1/TR from Microsemi is a 100 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation at 250 mA test current with 1600 Ω dynamic impedance, <0.01 µA reverse leakage at 76 V, and +0.100 %/°C temperature coefficient.
For engineers reviewing the JANS1N4135D-1/TR datasheet, JANS1N4135D-1/TR pinout, JANS1N4135D-1/TR application, or JANS1N4135D-1/TR equivalent, key selection criteria include Zener voltage accuracy (1%), radiation hardness, hermetic DO-35 packaging, MIL-spec qualification level, and low-noise performance in precision reference circuits.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with regulation defined at IZT = 250 mA and VR ≤ 76 V. Its internal metallurgical bond ensures mechanical robustness under thermal cycling and shock, while its hermetically sealed DO-35 glass package maintains long-term stability in harsh environments.
The JANS1N4135D-1/TR exhibits a positive temperature coefficient of +0.100 %/°C above 6.8 V, enabling predictable drift compensation in analog systems. Its noise density is specified at 1 µV/√Hz (typical), supporting low-noise reference design in instrumentation and telemetry signal chains.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4135US-1 | Same 100 V, 1% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy chassis mounts | Select when automated assembly, board density, or vibration resistance outweigh lead-forming flexibility |
| JANTXV1N4135D-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS) | Lacks full JANS screening (e.g., lot acceptance testing, radiation assurance documentation) | Acceptable for non-flight hardware or ground-test equipment where full JANS pedigree is not mandated |
Compared with JANS1N4135D-1/TR, the 1N4135US-1 enables higher-density layouts but sacrifices mechanical serviceability, while JANTXV1N4135D-1 reduces cost and lead time without compromising voltage accuracy-ideal for development platforms where full JANS traceability isn't required.

FAQ
What is the Zener voltage tolerance of JANS1N4135D-1/TR?
JANS1N4135D-1/TR has a nominal Zener voltage of 100 V with ±1% tolerance, as indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed over the full operating temperature range and qualifies the device for precision reference applications where absolute voltage accuracy is critical. The JANS1N4135D-1/TR achieves this via tight process control and 100% screening per MIL-PRF-19500/435.
Is JANS1N4135D-1/TR radiation hardened?
Yes, JANS1N4135D-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 glass package provide proven resistance to total ionizing dose (TID), making it suitable for low-Earth orbit (LEO) and medium-Earth orbit (MEO) satellite subsystems. No additional shielding or derating is required for typical space radiation environments.
What does the "TR" suffix mean in JANS1N4135D-1/TR?
The "TR" suffix in JANS1N4135D-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. This format includes continuous carrier tape with cover tape, moisture-sensitive level (MSL) labeling, and factory-certified quantity verification. The "TR" version retains identical electrical, mechanical, and qualification characteristics as the bulk or ammo-pack versions of JANS1N4135D-1/TR.
What is the maximum reverse leakage current for JANS1N4135D-1/TR?
JANS1N4135D-1/TR has a maximum reverse leakage current (IR) of 0.01 µA at VR = 76 V, per the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This ultra-low leakage ensures minimal error current in high-impedance reference divider networks and preserves accuracy in battery-powered or low-power telemetry systems using JANS1N4135D-1/TR.
Can JANS1N4135D-1/TR be used in place of commercial-grade 1N4135 diodes?
JANS1N4135D-1/TR is not a drop-in replacement for commercial 1N4135 variants due to stricter screening, enhanced reliability testing, and full JANS-level qualification per MIL-PRF-19500/435. While electrically compatible, JANS1N4135D-1/TR requires adherence to military handling, storage, and soldering protocols-including pre-bake and controlled thermal profiles. Its use in commercial systems adds cost and complexity without functional benefit unless high-reliability assurance is mandated.
