Product details
Overview
JAN1N4135C-1/TR from Microsemi is a 100 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4135C-1/TR datasheet, JAN1N4135C-1/TR pinout, JAN1N4135C-1/TR application, or JAN1N4135C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), radiation hardness, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 100 V at 250 mA test current, dynamic impedance of 1600 Ω at IZT, and reverse leakage current ≤0.01 µA at VR = 80 V. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
The JAN1N4135C-1/TR exhibits a positive temperature coefficient of +0.100 %/°C and maximum noise density of 1 µV/√Hz - verified at 1 kHz–3 kHz bandwidth - making it suitable for low-noise reference circuits where voltage stability across temperature and time is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 100 V ±2% at 250 mA - enables precise 100 V rail regulation with tight tolerance for mission-critical analog references. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - supports operation in high-temp environments with defined thermal margin. |
| Dynamic Impedance ZZT | 1600 Ω at IZT = 250 mA - determines output impedance in shunt regulation; impacts load regulation error under varying current. |
| Noise Density ND | 1 µV/√Hz - specifies broadband RMS noise floor; critical for low-drift voltage references in instrumentation and telemetry. |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift with temperature; allows accurate compensation in wide-temperature-range designs. |
| Reverse Leakage IR | ≤0.01 µA at VR = 80 V - ensures minimal parasitic current draw in high-impedance bias networks. |
| Junction Temp Range | −65 to +175 °C - validated for extended operation in space, avionics, and nuclear-hardened systems. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with cathode indicated by color band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lowest potential point; defines return path for Zener current. |
| Cathode | Regulated output node | Banded end; connected to input supply; maintains 100 V relative to anode during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 qualification | JANS-level reliability certified for spaceflight, missile guidance, and nuclear command systems. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and mechanical vibration. |
| Radiation hardness | Inherently radiation-tolerant per Microsemi MicroNote 050 - no additional shielding required for TID up to 100 krad(Si). |
| Low capacitance | Typical <2 pF - minimizes AC coupling and high-frequency instability in precision reference paths. |
| ESD immunity | Non-sensitive per MIL-STD-750 method 1020 - withstands handling without protection circuitry. |

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; unsuitable for through-hole prototyping or legacy chassis mounts. | Select when automated assembly, board space constraints, or vibration resistance outweigh lead-forming flexibility. |
| JANTXV1N4135C-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level (not JANS); lower screening rigor. | Approved for high-reliability ground systems and non-flight avionics; not cleared for launch-critical hardware. | Select for cost-sensitive defense programs where JANS qualification is not mandated by system specification. |
Compared with JAN1N4135C-1/TR, the 1N4135US-1 offers SMT compatibility at the expense of mechanical serviceability, while JANTXV1N4135C-1 reduces qualification cost without sacrificing Zener performance - enabling tiered sourcing across program maturity stages.

FAQ
What is the Zener voltage tolerance for JAN1N4135C-1/TR?
The "C" suffix in JAN1N4135C-1/TR denotes a ±2% Zener voltage tolerance at 250 mA test current, per the part nomenclature table in Microsemi T4-LDS-0245-2. This tighter tolerance than standard 5% parts enables higher-accuracy regulation in precision reference designs without external trimming.
Is JAN1N4135C-1/TR suitable for space applications?
Yes - JAN1N4135C-1/TR is qualified to JANS level per MIL-PRF-19500/435, including radiation hardness per Microsemi MicroNote 050. It is approved for use in spaceflight systems where total ionizing dose (TID) resilience and long-term parametric stability under vacuum and thermal cycling are required.
What is the maximum reverse leakage current for JAN1N4135C-1/TR?
JAN1N4135C-1/TR has a maximum reverse leakage current (IR) of 0.01 µA at VR = 80 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This ultra-low leakage supports high-impedance bias networks in low-power telemetry front-ends.
Does JAN1N4135C-1/TR require derating above 25 °C?
Yes - JAN1N4135C-1/TR must be linearly derated from 500 mW starting at 25 °C ambient, reaching zero dissipation at +175 °C, per Figure 2 in the datasheet. Derating follows a slope of −3.57 mW/°C, ensuring safe operation within its −65 to +175 °C junction temperature range.
What does the "TR" suffix indicate in JAN1N4135C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. The base part JAN1N4135C-1 remains electrically and mechanically identical; only packaging format changes - with reel quantities subject to factory consultation per the Mechanical and Packaging section.
