Product details
Overview
1N4107-1 from Microsemi is a 500 mW, 13.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANTXV level per MIL-PRF-19500/435, with 200 Ω dynamic impedance at 250 mA, 0.05 µA max reverse leakage at 10.4 V, and +0.080 %/°C temperature coefficient - used for precision voltage regulation in military power supplies and analog reference circuits.
For engineers reviewing the 1N4107-1 datasheet, 1N4107-1 pinout, 1N4107-1 application, or 1N4107-1 equivalent, key selection criteria include Zener voltage tolerance, junction-to-lead thermal resistance (250 °C/W), noise density (≤1 µV/√Hz), RoHS compliance status, and MIL-qualified reliability level.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgical bond ensures stable voltage reference under thermal cycling and radiation exposure.
It delivers 13.0 V regulation at 250 mA test current (IZT), with dynamic impedance of 200 Ω measured at 10% rms AC superimposed on IZT, and exhibits minimal capacitance (<2 pF typical at 13 V) per Figure 3 - critical for low-noise analog references and high-frequency bypass stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.0 V ±5% at 250 mA - defines nominal regulation point with tight tolerance for reference accuracy |
| Power Dissipation | 500 mW at 25 °C lead temperature - sets maximum continuous DC power before derating begins at 50 °C |
| Dynamic Impedance ZZT | 200 Ω at 250 mA - determines output impedance in regulation region, affecting load regulation error |
| Reverse Leakage IR | 0.05 µA max at 10.4 V - ensures minimal quiescent current in standby or high-impedance bias networks |
| Temp. Coefficient αVZ | +0.080 %/°C - quantifies drift rate over temperature; enables compensation in precision references |
| Noise Density ND | ≤1 µV/√Hz - supports low-noise applications such as sensor excitation and ADC reference buffers |
| Junction Temp. Range | –65 to +175 °C - enables operation in extended industrial and aerospace environments |
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. Weight ≈ 0.2 g; body diameter 1.42–2.29 mm, length 3.56–5.08 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; reverse-biased operation requires cathode > anode |
| Cathode | Regulated output node | Banded end; held at stable 13.0 V above anode when reverse current ≥ IZK |
Key Features
| Feature | Design Value |
|---|---|
| Metallurgical bond construction | Enables stable long-term Zener voltage and radiation hardness per MicroNote 050 |
| MIL-PRF-19500/435 qualification | Validated reliability up to JANTXV level for mission-critical defense and space systems |
| Low noise density | ≤1 µV/√Hz at 13 V supports high-resolution analog signal chains without added filtering |
| Minimal junction capacitance | Typical <2 pF at 13 V - preserves bandwidth in RF bias and fast-switching regulator feedback paths |
| ESD immunity | Non-sensitive per MIL-STD-750 Method 1020 - eliminates need for external ESD protection in handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V nominal, ±5%, 1 W rating, DO-41 package, no MIL qualification | Commercial industrial power supplies only; not suitable for aerospace or radiation environments | Select when higher power (1 W) is needed and MIL-qualification is unnecessary |
| 1N5242B | 12 V nominal, ±5%, 500 mW, DO-35, commercial grade only, no JANTXV option | Lacks military screening and radiation hardness; limited to benign terrestrial environments | Choose for cost-sensitive consumer or telecom applications where reliability beyond commercial spec is not required |
Compared with 1N4107-1, the 1N4742A offers higher power but no MIL-qualification or radiation tolerance, while the 1N5242B matches power and package but lacks JANTXV screening and proven hardness - making 1N4107-1 the sole choice for regulated 13 V references in flight-critical systems.

FAQ
What is the Zener voltage tolerance for the 1N4107-1?
The 1N4107-1 has a nominal Zener voltage of 13.0 V with a standard tolerance of ±5%, as defined 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 the 1N4107-1 RoHS compliant?
The 1N4107-1 is available in RoHS-compliant versions marked with the "e3" suffix (e.g., 1N4107-1e3), but only for commercial-grade units. JANTXV and higher reliability levels retain tin-lead plating per MIL-STD-750 and are not RoHS compliant. Always verify suffix and grade on the ordering part number.
What is the maximum reverse leakage current for the 1N4107-1?
The 1N4107-1 specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 10.4 V (80% of nominal VZ), per the Electrical Characteristics table. This ultra-low leakage supports high-impedance bias networks and minimizes error in precision reference applications.
Does the 1N4107-1 have radiation hardness certification?
Yes, the 1N4107-1 exhibits inherent radiation hardness as documented in Microsemi MicroNote 050, due to its metallurgically bonded construction and glass DO-35 package. While not individually certified per MIL-STD-883, its performance under total ionizing dose (TID) and displacement damage is validated across the qualified family.
What is the thermal resistance from junction to lead for the 1N4107-1?
The 1N4107-1 has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from the body, per Maximum Ratings table. This value enables accurate thermal modeling for power derating in conduction-cooled PCB layouts.
