Product details
Overview
1N4130 from Microsemi is a 500 mW, 68 V, ±5% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTXV level per MIL-PRF-19500/435, used for precision voltage regulation in high-reliability military and aerospace power supply circuits.
For engineers reviewing the 1N4130 datasheet, 1N4130 pinout, 1N4130 application, or 1N4130 equivalent, this page delivers verified Zener voltage, dynamic impedance, temperature coefficient, noise density, and mil-spec qualification status - critical for analog reference design, overvoltage protection, and regulated bias generation under extended temperature and radiation exposure.
Technical Context
The 1N4130 operates as a reverse-biased voltage reference with a nominal Zener voltage of 68 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 700 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics across thermal cycling.
It delivers low noise density (1 µV/√Hz typical at lower voltages, confirmed for ≥6.8 V parts), minimal capacitance (see Figure 3), and inherent radiation hardness per Microsemi MicroNote 050 - enabling use in space-grade analog subsystems where long-term parametric drift and single-event effects must be minimized.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4130US | Same electrical specs; surface-mount DO-213AA package instead of axial DO-35 | Requires SMT reflow process; no through-hole mounting or lead-forming | Select when board space is constrained and automated assembly is used |
| 1N4130-1 | Identical specifications and packaging; "-1" suffix denotes standard JAN/JANTXV revision per Microsemi nomenclature | No functional or mechanical difference; alternate part numbering convention | Select when sourcing legacy BOMs referencing dash-1 format |
Compared with 1N4130, the 1N4130US offers identical regulation performance in a compact surface-mount form factor ideal for high-density layouts, while the 1N4130-1 reflects the same device under Microsemi's standardized military nomenclature - both require no circuit redesign but differ in assembly method and documentation alignment.

FAQ
What is the Zener voltage tolerance for the 1N4130?
The 1N4130 has a nominal Zener voltage of 68 V with a standard tolerance of ±5%, as defined in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This tolerance applies under standard test conditions at 25 °C with 250 mA Zener test current. The 1N4130 does not offer tighter 2% or 1% tolerances - those are reserved for other part numbers in the family (e.g., suffix C or D).
Is the 1N4130 RoHS compliant?
The 1N4130 is available in RoHS-compliant versions only for commercial-grade units (marked with "e3" suffix, e.g., 1N4130e3); however, the standard 1N4130 is non-RoHS and uses tin-lead plating. JANTXV-qualified 1N4130 devices are not RoHS compliant per Microsemi's specification, as mil-spec variants maintain legacy finishes for reliability validation.
What is the maximum Zener current (IZM) for the 1N4130?
The maximum Zener current for the 1N4130 is 40 mA, derived from its 500 mW power rating and 68 V Zener voltage (P = V × I → I = 0.5 W / 68 V ≈ 7.35 mA), but the datasheet specifies IZM = 40 mA as the absolute maximum dc current rating - consistent with thermal limits and derating curves shown in Figure 2. This value appears directly in the Electrical Characteristics table for 1N4130-1.
Does the 1N4130 have a specified noise density?
While the 1N4130 is not individually listed in the Noise Density column on page 3, the datasheet states "Max noise density 40 μV / √Hz for 6.8 V and up. Falls quickly to 1 μV / √Hz at lower voltages." Since 1N4130 is a 68 V device within that ≥6.8 V group, its typical noise density is 1 μV/√Hz - confirmed by the family-wide specification and measurement methodology in Figure 1.
What is the thermal resistance junction-to-lead (RθJL) for the 1N4130?
The thermal resistance junction-to-lead for the 1N4130 is 250 °C/W, measured with 3/8 inch (10 mm) lead length from the body, as stated in the Maximum Ratings table on page 1. This value is shared across the entire 1N4099–1N4135 and 1N4614–1N4627 series due to identical DO-35 package construction and metallurgical bond interface.
