Product details
Overview
JAN1N4135-1 from Microsemi is a 100 V, 500 mW axial-leaded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANS level per MIL-PRF-19500/435, with ±5% voltage tolerance, 1600 Ω dynamic impedance at 250 mA test current, and 3.8 mA maximum temperature coefficient of +0.100 %/°C. It delivers stable voltage regulation in high-reliability aerospace power conditioning circuits.
For engineers reviewing the JAN1N4135-1 datasheet, JAN1N4135-1 pinout, JAN1N4135-1 application, or JAN1N4135-1 equivalent, key selection criteria include Zener voltage accuracy under thermal stress, low noise density (<1 μV/√Hz below 6.8 V), hermetic glass packaging for radiation-hardened environments, and compliance with military reliability screening levels up to JANS.
Technical Context
The JAN1N4135-1 operates as a precision shunt voltage regulator with metallurgically bonded junction construction, enabling stable breakdown behavior across -65 °C to +175 °C junction temperature range. Its 100 V nominal Zener voltage is specified at 250 mA test current (IZT), with 1600 Ω dynamic impedance (ZZT) and 0.01 µA reverse leakage (IR) at 76 V.
Designed for high-reliability mil-aero systems, it features minimal capacitance (~1.5 pF typical), non-ESD-sensitive operation per MIL-STD-750 Method 1020, and inherent radiation hardness documented in Microsemi MicroNote 050. Power dissipation is linearly derated from 500 mW at 25 °C to zero at 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 100 V at 250 mA - defines precise regulation point for high-voltage reference and clamp circuits |
| Power Dissipation | 500 mW @ 25 °C - supports continuous regulation in compact axial-leaded layouts without forced cooling |
| Dynamic Impedance (ZZT) | 1600 Ω @ IZT = 250 mA - determines output voltage stability under load transients |
| Reverse Leakage (IR) | 0.01 µA @ VR = 76 V - ensures minimal standby current in high-impedance bias networks |
| Temp Coefficient (αVZ) | +0.100 %/°C - quantifies voltage drift over temperature; critical for wide-range environmental operation |
| Noise Density (ND) | <1 µV/√Hz - enables use in low-noise analog references where spectral purity matters |
| Junction Temp Range | -65 to +175 °C - validated for extended operation in space-grade and engine-mounted electronics |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by color band; banded end must be biased positive for Zener regulation. Hermetically sealed, tin-lead or RoHS-compliant matte-tin plating, ~0.2 g mass, 1.0–1.5 inch lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference | Connected to system ground or lower-potential node during regulation; defines polarity for proper biasing |
| Cathode (banded end) | Zener breakdown terminal | Connected to regulated voltage rail; must be held at higher potential than anode to activate Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bond construction | Ensures long-term parameter stability and resistance to thermal cycling-induced degradation in harsh environments |
| MIL-PRF-19500/435 qualification (JANS level) | Validates performance under rigorous screening including burn-in, temperature cycling, and hermeticity testing for spaceflight use |
| Low noise density (<1 µV/√Hz) | Supports precision analog references where broadband noise would corrupt signal integrity or ADC accuracy |
| Radiation hardness (MicroNote 050) | Enables deployment in satellite power systems exposed to total ionizing dose (TID) without functional degradation |
| Non-ESD-sensitive per MIL-STD-750 Method 1020 | Eliminates need for ESD handling controls during assembly, reducing manufacturing overhead in cleanroom lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4135US | Same 100 V Zener voltage, but in surface-mount DO-213AA package; no military qualification | Lacks MIL-PRF-19500/435 screening; unsuitable for JANS-level programs requiring hermetic axial leads | Select when board space is constrained and radiation/environmental specs are commercial-grade only |
| JANTXV1N4135-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level (not JANS); lower screening rigor | Approved for high-reliability avionics but not spaceflight; excludes some JANS-specific tests like neutron irradiation | Select when full JANS qualification is unnecessary and cost reduction is prioritized without sacrificing mechanical form |
Compared with JAN1N4135-1, 1N4135US trades military reliability for SMT compatibility, while JANTXV1N4135-1 retains axial form and most screening but omits JANS-specific radiation and hermeticity validation-making it suitable for airborne, not orbital, deployment.

FAQ
What is the Zener voltage tolerance for JAN1N4135-1?
The JAN1N4135-1 has a nominal Zener voltage of 100 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This tolerance applies at 25 °C with the device in thermal equilibrium and is maintained across the full JANS qualification screening process.
Does JAN1N4135-1 require heatsinking in typical operation?
No, JAN1N4135-1 does not require external heatsinking under standard conditions. Its 500 mW power rating and 250 °C/W thermal resistance junction-to-lead (with 3/8″ lead length) allow safe operation at full power with minimal lead length on FR4 PCBs. Derating begins linearly at 50 °C ambient, reaching zero dissipation at 175 °C.
Is JAN1N4135-1 RoHS compliant?
No, JAN1N4135-1 is not RoHS compliant. Per the nomenclature table on page 2 of T4-LDS-0245-2, RoHS compliance (e3 suffix) is available only on commercial-grade versions. JAN-level parts like JAN1N4135-1 use traditional tin-lead plating and are exempt from RoHS under military procurement waivers.
What is the maximum reverse leakage current for JAN1N4135-1?
The maximum reverse leakage current (IR) for JAN1N4135-1 is 0.01 µA at VR = 76 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 and minimizes error in precision reference applications.
Can JAN1N4135-1 be used in surface-mount designs?
No, JAN1N4135-1 is exclusively packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not compatible with surface-mount assembly. For SMT equivalents, consider the 1N4135UR-1 in DO-216 or 1N4135US in DO-213AA - neither of which carry JAN or JANS qualification.
