Product details
Overview
JAN1N4131C-1 from Microsemi is a 500 mW, 75 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JAN reliability level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 700 Ω maximum dynamic impedance at 250 mA test current, and 5.1 µA maximum reverse leakage at 60 V.
For engineers reviewing the JAN1N4131C-1 datasheet, JAN1N4131C-1 pinout, JAN1N4131C-1 application, or JAN1N4131C-1 equivalent, key selection criteria include Zener voltage accuracy, low noise density (≤1 µV/√Hz below 6.8 V), radiation hardness, hermetic glass sealing, and military-grade thermal derating behavior across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a precision shunt voltage reference in high-reliability analog and power-supply circuits, leveraging metallurgical bonding for stable breakdown characteristics and minimal parameter drift over temperature and time. Its 75 V nominal Zener voltage is specified at 250 mA test current with ±2% tolerance, and it exhibits a positive temperature coefficient of +0.100 %/°C.
The JAN1N4131C-1 delivers regulated output under reverse-biased conditions with cathode band marking polarity, supports 500 mW average power dissipation at 25 °C (linearly derated to zero at 175 °C), and maintains ≤5.1 µA reverse leakage at VR = 60 V - critical for low-power biasing and reference stability in aerospace and defense systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 75 V ±2% at IZT = 250 mA - ensures tight regulation in high-voltage reference and overvoltage clamp circuits. |
| Power Dissipation PM(AV) | 500 mW at TC = 25 °C, derated linearly to zero at 175 °C - defines safe operating area for continuous DC regulation. |
| Dynamic Impedance ZZT | 700 Ω max at IZT = 250 mA - determines output voltage variation under load current changes. |
| Reverse Leakage IR | ≤5.1 µA at VR = 60 V - guarantees low standby current in precision bias networks. |
| Noise Density ND | ≤1 µV/√Hz (typical) - enables use in low-noise analog references where spectral purity matters. |
| Temp Coefficient αVZ | +0.100 %/°C - quantifies voltage drift with ambient change; critical for temperature-stable designs. |
| Junction Temp Range | –65 °C to +175 °C - supports operation in extreme environmental conditions per MIL-PRF-19500/435. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with hermetically sealed construction, tin-lead or RoHS-compliant matte-tin plating, cathode indicated by color band, and approximate weight of 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node during Zener regulation; carries full reverse current when cathode is biased positively. |
| Cathode (banded end) | Zener regulation input / voltage reference node | Biased positively relative to anode to enter breakdown; serves as stable 75 V reference point for feedback, clamping, or biasing functions. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4131D-1 | Same 75 V nominal Zener voltage but ±1% tolerance (vs. ±2% for JAN1N4131C-1); identical package, power rating, and MIL qualification level. | Required where tighter initial voltage accuracy is needed for calibration-critical systems; higher cost and longer lead time. | Select JAN1N4131D-1 only if system-level calibration budget demands sub-1% absolute reference error. |
| JANS1N4131C-1 | Identical electrical specs and ±2% tolerance, but qualified to JANS (highest MIL-PRF-19500/435 level) with full lot traceability, extended screening, and radiation testing. | Required for manned spaceflight, strategic weapons, or other JANS-mandated programs; not interchangeable without requalification. | Choose JANS1N4131C-1 only when program requirements explicitly mandate JANS-level reliability documentation and screening. |
Compared with JAN1N4131C-1, JAN1N4131D-1 offers improved initial accuracy at higher cost, while JANS1N4131C-1 provides enhanced process control and radiation assurance - neither is pin-compatible in the sense of drop-in replacement without revalidation per program-specific qualification protocols.

FAQ
What is the Zener voltage tolerance of JAN1N4131C-1?
JAN1N4131C-1 has a nominal Zener voltage of 75 V with a tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when used within its derated power envelope.
Is JAN1N4131C-1 RoHS compliant?
No, JAN1N4131C-1 is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4131C-1e3); JAN-level parts retain traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements due to their military qualification status and reliability-critical use cases.
What is the maximum reverse leakage current for JAN1N4131C-1?
JAN1N4131C-1 specifies a maximum reverse leakage current (IR) of 5.1 µA at VR = 60 V and 25 °C. This value is measured under standardized test conditions and remains valid across the full operational temperature range when power dissipation stays within the derated limits defined in Figure 2 of the datasheet.
Can JAN1N4131C-1 be used in surface-mount designs?
No, JAN1N4131C-1 is packaged exclusively in the axial-leaded DO-35 (DO-204AH) glass case and is not suitable for surface-mount assembly. For SMT equivalents, Microsemi offers the 1N4131UR-1 in DO-213AA and 1PMT4131 in DO-216 packages - but these are commercial-grade and lack JAN qualification.
What does the "JAN" prefix signify for JAN1N4131C-1?
The "JAN" prefix indicates that JAN1N4131C-1 is qualified to the lowest military reliability level under MIL-PRF-19500/435, including lot traceability, extended temperature testing, and screening for mechanical and electrical parameters - distinguishing it from commercial 1N4131C-1 parts which lack formal military qualification documentation and process controls.
