Product details
Overview
JAN1N4135D-1 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 voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4135D-1 datasheet, JAN1N4135D-1 pinout, JAN1N4135D-1 application, or JAN1N4135D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), 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 regulator with a nominal Zener voltage of 100 V at 250 mA test current, exhibiting dynamic impedance of 1600 Ω and temperature coefficient of +0.100 %/°C. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in reverse-biased mode with cathode band positive, it delivers regulated voltage across wide current ranges (IZK to IZM = 40 mA) while maintaining ≤0.01 µA reverse leakage at VR = 80 V and offering minimal capacitance (~4 pF typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 100 V ±1% at 250 mA - enables precise reference generation in high-voltage feedback loops |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - supports operation in high-temp avionics enclosures |
| Zener Impedance (ZZT) | 1600 Ω max at 250 mA - limits output voltage variation under load transients |
| Noise Density (ND) | 1 µV/√Hz at 250 mA - critical for low-noise analog references and sensor excitation |
| Reverse Leakage (IR) | ≤0.01 µA at 80 V - ensures minimal quiescent current in standby regulation |
| Temp Coefficient (αVZ) | +0.100 %/°C - predictable drift behavior simplifies temperature compensation design |
| Junction Temp Range | –65 to +175 °C - validated for space-grade thermal cycling and reflow survivability |

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, 1% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated assembly and board space constraints outweigh manual serviceability needs |
| JANTXV1N4135D | Identical electrical specs; differs only in screening level (JANTXV vs JANS) and test documentation traceability | Approved for Class B space applications but not Class S; lower cost than JANS for non-flight-hardware use | Choose for ground-test equipment or subsystems where full JANS screening is not mandated |
Compared with JAN1N4135D-1, 1N4135US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4135D provides equivalent functionality with reduced screening rigor-both serve as viable alternatives depending on mechanical integration and qualification requirements.

FAQ
What is the Zener voltage tolerance of JAN1N4135D-1?
JAN1N4135D-1 has a nominal Zener voltage of 100 V with ±1% tolerance, as indicated by the "D" suffix in its nomenclature per Microsemi's part numbering standard. This tight tolerance is verified during JANS-level screening and applies at 250 mA test current and 25 °C ambient. The specification remains valid across the full –65 to +175 °C junction temperature range with predictable drift governed by its +0.100 %/°C temperature coefficient.
Is JAN1N4135D-1 RoHS compliant?
No, JAN1N4135D-1 is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4135D-1e3); military-grade JAN/JANTX/JANTXV/JANS parts like JAN1N4135D-1 retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements and avoid reliability risks associated with lead-free finishes in high-reliability applications.
What is the maximum Zener current (IZM) for JAN1N4135D-1?
The maximum Zener current IZM for JAN1N4135D-1 is 40 mA, derived from its 500 mW power rating and 100 V Zener voltage (P = V × I → I = 0.5 W / 100 V = 5 mA theoretical, but datasheet specifies 40 mA due to thermal design margin and derating curve). This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 and reflects safe continuous operation at 25 °C lead temperature before linear derating begins at 50 °C.
Does JAN1N4135D-1 require heatsinking in typical applications?
JAN1N4135D-1 does not require external heatsinking in most applications due to its DO-35 package's specified thermal resistance of 250 °C/W junction-to-lead (RθJL) at 3/8″ lead length. At 40 mA and 100 V, power dissipation is 4 W - exceeding its 500 mW rating - so actual operation stays well below IZM. Typical use at ≤10 mA yields <1 W dissipation, manageable with standard PCB copper pads per JEDEC mounting guidelines in the datasheet.
How is polarity marked on JAN1N4135D-1?
JAN1N4135D-1 uses a single black cathode band to indicate polarity, consistent with DO-35 industry convention. The banded end is the cathode and must be held positive relative to the unmarked (anode) end for proper Zener regulation. This marking is visible on the glass body and is verified during MIL-PRF-19500/435 visual inspection; polarity reversal will cause forward conduction rather than regulation and may damage the device if sustained.
