Product details
Overview
1N4107/TR from Microsemi is a 500 mW, 13.0 V ±5% Zener diode in DO-35 glass axial-leaded package, qualified to JANTX level per MIL-PRF-19500/435, with 200 Ω dynamic impedance at 250 mA and 0.05 µA reverse leakage at 10.4 V. It delivers stable voltage regulation in precision reference and power supply feedback circuits across military, aerospace, and industrial systems.
For engineers reviewing the 1N4107/TR datasheet, 1N4107/TR pinout, 1N4107/TR application, or 1N4107/TR equivalent, this page provides verified electrical parameters, thermal derating behavior, noise density (1 µV/√Hz), RoHS-compliant commercial availability, and direct alternatives for high-reliability Zener regulation design.
Technical Context
The 1N4107/TR operates as a two-terminal voltage reference device, biased in reverse breakdown with cathode band indicating polarity. Its metallurgically bonded junction ensures low noise and radiation hardness, supporting operation from –65 °C to +175 °C with 250 °C/W junction-to-lead thermal resistance at 10 mm lead length.
It exhibits a +0.080 %/°C temperature coefficient and maintains ≤200 Ω dynamic impedance (ZZT) at IZT = 250 mA, enabling stable regulation under varying load and temperature conditions without external compensation.
Key Specifications

|---|---|
| Zener Voltage VZ | 13.0 V ±5% at 250 mA - sets precise reference point for feedback loops and analog thresholds |
| Power Dissipation | 500 mW @ 25 °C, linearly derated to zero at 175 °C - defines maximum continuous thermal load on PCB |
| Dynamic Impedance ZZT | 200 Ω @ 250 mA - determines output voltage stability under current transients |
| Reverse Leakage IR | 0.05 µA @ 10.4 V - ensures minimal error contribution in high-impedance bias networks |
| Noise Density ND | 1 µV/√Hz @ 250 mA - critical for low-noise references in instrumentation and ADC front-ends |
| Temp Coefficient αVZ | +0.080 %/°C - quantifies drift magnitude over operating temperature range |
| Junction Temp Range | –65 °C to +175 °C - supports extended-environment deployment without derating penalties |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4107US | Same electrical specs, but in surface-mount DO-213AA package; no axial leads | Requires SMT reflow process; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated assembly is used |
| 1N4743A | 13 V ±5%, 1 W rating, DO-41 package; higher power but larger footprint and +0.08 %/°C TC | Supports higher current loads (up to 76 mA vs. 38 mA for 1N4107/TR); less suitable for high-density layouts | Select when >500 mW dissipation is needed and MIL-spec is not required |
Compared with 1N4107US and 1N4743A, the 1N4107/TR uniquely balances JANTX-level reliability, DO-35 axial form factor, and 1 µV/√Hz noise-making it optimal for legacy-military upgrades and space-constrained high-integrity analog designs.

FAQ
What is the Zener voltage tolerance of the 1N4107/TR?
The 1N4107/TR has a nominal Zener voltage of 13.0 V with a standard tolerance of ±5%, as defined in the JEDEC specification and confirmed in Microsemi's T4-LDS-0245-2 datasheet. This tolerance applies at 250 mA test current and 25 °C ambient temperature, and remains valid across its full operating temperature range when combined with its +0.080 %/°C temperature coefficient.
Is the 1N4107/TR RoHS compliant?
Yes, the 1N4107/TR is available in RoHS-compliant versions marked with the "e3" suffix (e.g., 1N4107-1e3/TR), featuring annealed matte-tin plating. RoHS compliance is limited to commercial-grade units; MIL-spec variants (JAN/JANTX) retain traditional tin-lead plating per qualification requirements.
What is the maximum reverse leakage current for the 1N4107/TR?
The 1N4107/TR specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 10.4 V (80% of VZ), measured at 25 °C. This ultra-low leakage supports high-impedance bias networks and minimizes error in precision reference applications where leakage-induced voltage drop must be negligible.
Can the 1N4107/TR be used in surface-mount designs?
No-the 1N4107/TR is packaged exclusively in the axial-leaded DO-35 (DO-204AH) glass case. For surface-mount equivalents, Microsemi offers the 1N4107US in DO-213AA package. The "TR" suffix denotes tape-and-reel packaging for through-hole automated insertion-not SMT compatibility.
What is the thermal resistance of the 1N4107/TR?
The 1N4107/TR has a junction-to-lead thermal resistance (RθJL) of 250 °C/W when mounted with 10 mm lead length from body, and a junction-to-ambient resistance (RθJA) of 300 °C/W on FR4 board with specified copper pad geometry. These values govern safe power derating-500 mW linearly decreases to zero between 50 °C and 175 °C lead temperature.
