Product details
Overview
1N4130-1 from Microsemi is a 500 mW, 68 V metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435, with ±5% voltage tolerance, 700 Ω dynamic impedance at 250 mA, and 40 µA max reverse leakage at 54.4 V. It regulates voltage in precision reference and high-reliability power supply circuits.
For engineers reviewing the 1N4130-1 datasheet, 1N4130-1 pinout, 1N4130-1 application, or 1N4130-1 equivalent, this page delivers verified Zener voltage, thermal derating behavior, noise density (1 µV/√Hz), junction temperature range (–65°C to +175°C), and military qualification level - all critical for aerospace, defense, and industrial analog design.
Technical Context
The 1N4130-1 operates as a two-terminal voltage reference device, conducting in reverse breakdown with stable regulation across 10 mA to 40 mA nominal current range. Its metallurgical bond construction ensures low long-term drift and radiation hardness per MicroNote 050, while its DO-35 glass package provides hermetic sealing and ESD immunity per MIL-STD-750 method 1020.
It exhibits a positive temperature coefficient of +0.100 %/°C above 6.2 V, enabling predictable thermal tracking in series-connected references. Dynamic impedance is measured at 10% AC modulation (25 µA rms) superimposed on 250 mA DC test current, yielding 700 Ω typical value - critical for low-noise regulator stability under varying load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 68 V ±5% at 250 mA - defines precise regulation point for mid-range high-voltage references. |
| Power Dissipation | 500 mW at 25°C, linearly derated to zero at 175°C - sets maximum continuous thermal load on PCB layout. |
| Dynamic Impedance ZZT | 700 Ω at 250 mA - determines output voltage variation under load transients; lower values improve regulation accuracy. |
| Reverse Leakage IR | ≤40 µA at 54.4 V - ensures minimal quiescent current in standby or low-power bias networks. |
| Noise Density | 1 µV/√Hz - enables use in ultra-low-noise analog references where broadband voltage stability is required. |
| Junction Temp Range | –65°C to +175°C - supports operation in extended-temperature avionics, downhole, and space-qualified systems. |
| Temp Coefficient αVZ | +0.100 %/°C - allows predictable thermal drift compensation in multi-Zener reference strings. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package: hermetically sealed, cathode indicated by single black band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026; weight ≈ 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; reverse-biased operation requires cathode at higher potential. |
| Cathode | Zener regulation terminal / voltage reference output | Banded end; supplies regulated 68 V when reverse-biased; must be held ≥68 V above anode for stable breakdown. |

FAQ
What is the Zener voltage tolerance for 1N4130-1?
The 1N4130-1 has a nominal Zener voltage of 68 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 Rev. 1. This tolerance applies at 250 mA test current and 25°C ambient temperature, and is consistent across JAN, JANTX, JANTXV, and JANS reliability levels.
Is 1N4130-1 suitable for high-temperature operation?
Yes, the 1N4130-1 supports junction temperatures from –65°C to +175°C and is rated for 500 mW power dissipation at 25°C, with linear derating to zero at 175°C. Its metallurgically bonded glass construction and DO-35 package enable reliable operation in extended-temperature environments such as avionics bays and downhole drilling electronics - fully validated per MIL-PRF-19500/435.
Does 1N4130-1 have radiation hardness certification?
Yes, the 1N4130-1 is inherently radiation hard as documented in Microsemi MicroNote 050, a result of its metallurgical bond construction and hermetic DO-35 packaging. While not individually tested per MIL-STD-883, its qualification to JANS level per MIL-PRF-19500/435 confirms suitability for radiation-intensive applications including satellite systems and nuclear instrumentation.
What is the maximum reverse leakage current for 1N4130-1?
The maximum reverse leakage current (IR) for 1N4130-1 is 40 µA at a reverse voltage (VR) of 54.4 V, as specified in the Electrical Characteristics table. This value is measured at 25°C and reflects worst-case leakage under sub-breakdown conditions - critical for low-power bias networks and standby-mode circuits.
Can 1N4130-1 be used in low-noise analog references?
Yes, the 1N4130-1 delivers 1 µV/√Hz noise density at its 68 V Zener voltage, measured using a 1 kHz–3 kHz bandpass filter at 25°C. This ultra-low noise performance - combined with its stable tempco (+0.100 %/°C) and low dynamic impedance (700 Ω) - makes it suitable for precision analog references in data acquisition systems and low-phase-noise oscillator biasing circuits.
