Product details
Overview
JAN1N4130C-1 from Microsemi is a 500 mW, 68 V, ±2% tolerance 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 JAN1N4130C-1 datasheet, JAN1N4130C-1 pinout, JAN1N4130C-1 application, or JAN1N4130C-1 equivalent, key selection criteria include its 68 V nominal Zener voltage at 250 mA test current, 700 Ω maximum dynamic impedance, 40 µV/√Hz noise density, and operation across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with a defined breakdown knee (IZK) and specified Zener test current (IZT = 250 mA), enabling stable reference generation under varying load and temperature conditions. Its metallurgical bond construction ensures low thermal resistance (RθJL = 250 °C/W) and radiation hardness per MicroNote 050.
The JAN1N4130C-1 exhibits a positive temperature coefficient of +0.100 %/°C, confirming predictable voltage drift over temperature, and maintains ≤0.01 µA reverse leakage at VR = 54.4 V - critical for low-power biasing and sensing circuits requiring minimal quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 68 V at IZT = 250 mA - defines precise regulation point for reference design |
| Zener Tolerance | ±2% - tighter than standard 5% parts, reducing calibration overhead in precision systems |
| Max Dynamic Impedance | 700 Ω at IZT - determines output voltage stability under load transients |
| Noise Density | 40 µV/√Hz - enables use in low-noise analog references and sensor excitation |
| Max Reverse Leakage | 0.01 µA at VR = 54.4 V - ensures minimal error current in high-impedance bias networks |
| Temp Coefficient αVZ | +0.100 %/°C - allows accurate prediction of voltage drift across full military temperature range |
| Power Dissipation | 500 mW at TC = 25 °C, derated linearly to zero at 175 °C - sets thermal design margin for PCB layout |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band; banded end is anode when used in forward conduction, but functions as cathode (positive terminal) during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Zener cathode connection | Connected to higher potential node during regulation; polarity marking is critical for correct circuit orientation |
| Cathode (non-banded end) | Zener anode connection | Connected to lower potential (e.g., ground or return path); completes reverse-biased regulation path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4130UR-1 | Same 68 V Zener voltage and ±2% tolerance, but in DO-213AA surface-mount package | Requires rework of through-hole PCB layout; suited for space-constrained avionics modules | Select when board real estate is limited and automated SMT assembly is available |
| JANTXV1N4130C | Identical electrical specs and DO-35 package, but qualified only to JANTXV (not JANS) per MIL-PRF-19500/435 | Approved for high-reliability programs requiring JANTXV screening but not full JANS radiation testing | Select when full JANS qualification is not mandated but extended temperature and screening are required |
Compared with JAN1N4130C-1, 1N4130UR-1 offers identical regulation performance in a smaller footprint but requires PCB redesign, while JANTXV1N4130C delivers matching functionality with reduced qualification scope-enabling cost and lead-time optimization where JANS-level radiation hardness is unnecessary.

FAQ
What is the Zener voltage and tolerance of JAN1N4130C-1?
JAN1N4130C-1 has a nominal Zener voltage of 68 V at 250 mA test current (IZT), with a tight ±2% tolerance. This value is measured under thermal equilibrium at 25 °C ambient and reflects the device's regulation point in shunt configuration. The "C" suffix explicitly denotes the 2% tolerance grade per Microsemi's nomenclature.
Is JAN1N4130C-1 qualified to JANS level per MIL-PRF-19500/435?
Yes, JAN1N4130C-1 is fully qualified to JANS level per MIL-PRF-19500/435, including radiation hardness assurance, extended temperature screening (–65 °C to +175 °C), and rigorous environmental stress testing. This qualification is confirmed in the T4-LDS-0245-2 datasheet and applies specifically to the JAN-prefix version with "C" tolerance.
What is the maximum reverse leakage current for JAN1N4130C-1?
JAN1N4130C-1 specifies a maximum reverse leakage current (IR) of 0.01 µA at VR = 54.4 V (80% of nominal Zener voltage). This ultra-low leakage supports high-impedance bias networks and precision reference applications where leakage-induced errors must be minimized.
Does JAN1N4130C-1 have a positive or negative temperature coefficient?
JAN1N4130C-1 has a positive temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases predictably with rising junction temperature. This behavior is typical for Zeners above ~5 V and enables accurate compensation modeling in wide-temperature-range power systems.
What package type does JAN1N4130C-1 use, and how is polarity marked?
JAN1N4130C-1 uses the DO-35 (DO-204AH) axial-leaded hermetically sealed glass package. Polarity is marked by a single cathode band near one end; during Zener operation, the banded end is the cathode and must be connected to the higher-potential node of the circuit.
