Product details
Overview
JAN1N4130D-1/TR from Microsemi is a 1% tolerance, 68 V, 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 JAN1N4130D-1/TR datasheet, JAN1N4130D-1/TR pinout, JAN1N4130D-1/TR application, or JAN1N4130D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (700 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.100 %/°C), and JANS-level radiation hardness.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 68 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across -65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
The diode features a cathode band polarity indicator and is rated for 0.5 W average power dissipation with linear derating above 50 °C lead temperature. It delivers 56.0 mA maximum Zener current (IZM) and maintains <0.01 µA reverse leakage at VR = 51.7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 68 V ±1% at 250 mA - enables precise reference generation in regulated DC-DC feedback loops. |
| Power Dissipation | 500 mW @ TC = 25 °C - supports stable operation in compact, convection-cooled military enclosures. |
| Dynamic Impedance | 700 Ω @ IZT = 250 mA - ensures minimal output voltage variation under load transients. |
| Noise Density | 1 µV/√Hz - critical for low-noise analog references in instrumentation and telemetry receivers. |
| Temp. Coefficient | +0.100 %/°C - provides predictable, monotonic drift over wide operating temperature ranges. |
| Max Reverse Leakage | 0.01 µA @ VR = 51.7 V - guarantees high impedance in off-state, minimizing standby current draw. |
| Junction Temp Range | -65 °C to +175 °C - validated for extended-life deployment in space-grade and engine-mounted systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4130C-1/TR | Same 68 V nominal voltage but ±2% tolerance instead of ±1%. | Acceptable where tighter voltage accuracy is not required, e.g., non-critical supply monitoring. | Select JAN1N4130C-1/TR only if system-level tolerance budget allows ±2% drift over temperature and life. |
| 1N4130US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used in automated SMT assembly lines where through-hole mounting is incompatible with board layout. | Choose 1N4130US-1 when PCB real estate or assembly process requires SMT compatibility without sacrificing JANS reliability. |
Compared with JAN1N4130D-1/TR, JAN1N4130C-1/TR trades 1% accuracy for broader tolerance margin, while 1N4130US-1 retains identical regulation performance in a surface-mount form factor-neither is pin-compatible due to differing packages, requiring layout revision.

What is the maximum Zener current (IZM) for JAN1N4130D-1/TR?
The maximum Zener current IZM for JAN1N4130D-1/TR is 51.7 mA, derived from its 500 mW power rating and 68 V nominal Zener voltage (P = V × I). This value assumes operation at 25 °C lead temperature; derating applies linearly above 50 °C per the published power curve.
Does JAN1N4130D-1/TR have low noise performance?
Yes, JAN1N4130D-1/TR exhibits a noise density of 1 µV/√Hz at 250 mA test current, among the lowest in its voltage class. This performance is confirmed in the manufacturer's characterization data and makes JAN1N4130D-1/TR appropriate for low-noise analog references in telemetry, instrumentation, and RF subsystems.
What package type does JAN1N4130D-1/TR use?
JAN1N4130D-1/TR uses the DO-35 (DO-204AH) axial-leaded, hermetically sealed glass package. Its dimensions conform to JEDEC standards, with a body diameter of 1.42–2.29 mm and overall length of 3.56–5.08 mm, enabling reliable through-hole mounting in high-vibration military and aerospace assemblies.
