Product details
Overview
1N4107 from Microsemi is a 500 mW, 13.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTXV level per MIL-PRF-19500/435. It delivers stable voltage regulation at 250 mA test current with 200 Ω dynamic impedance, low 0.05 µA reverse leakage at 10.4 V, and +0.080 %/°C temperature coefficient-used in precision reference and power supply feedback circuits.
For engineers reviewing the 1N4107 datasheet, 1N4107 pinout, 1N4107 application, or 1N4107 equivalent, this page provides verified Zener voltage, thermal derating behavior, noise density, RoHS compliance status, and military-grade qualification details critical for high-reliability analog design and aerospace power systems.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 13.0 V at 250 mA test current (IZT), exhibiting 200 Ω dynamic impedance (ZZT) and 0.05 µA maximum reverse leakage (IR) at 10.4 V (VR = 0.8 × VZ). Its metallurgical bond construction ensures stable breakdown characteristics across -65 °C to +175 °C junction temperature range.
The 1N4107 features +0.080 %/°C temperature coefficient, minimal capacitance (typical <2 pF per Figure 3), and 40 µV/√Hz max noise density above 6.8 V-enabling use in low-noise references where voltage drift and spectral purity are design-critical.

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, 1 W rating, DO-41 package, ±5% tolerance, +0.075 %/°C TC | Higher power but lower voltage; less suitable for 13 V-specific feedback networks | Select when higher dissipation margin is needed and 12 V regulation suffices |
| MMBZ5243B | 13 V nominal, 225 mW SMT package, ±5%, +0.08 %/°C TC, non-military grade | Surface-mount only; lacks MIL-PRF-19500 qualification and hermetic sealing | Select for commercial-grade space-constrained PCBs where military reliability not required |
Compared with 1N4107, the 1N4742A offers higher power but requires redesign of voltage-scaling networks, while the MMBZ5243B enables miniaturization but sacrifices radiation hardness, hermeticity, and JANTXV qualification essential for aerospace deployment.

FAQ
What is the Zener voltage tolerance for the 1N4107?
The 1N4107 has a nominal Zener voltage of 13.0 V with a standard tolerance of ±5% at 250 mA test current, as defined in the JEDEC-registered electrical characteristics table. This tolerance applies to commercial-grade parts; tighter tolerances (e.g., ±2% or ±1%) require different suffixes (C or D) not present in the base 1N4107 designation.
Is the 1N4107 RoHS compliant?
Yes, RoHS-compliant versions of the 1N4107 are available with the "e3" suffix (e.g., 1N4107-1e3), but only in commercial-grade configurations. Military-grade variants (JAN, JANTX, JANTXV, JANS) retain lead-based terminations per MIL-PRF-19500 requirements and are not RoHS compliant.
What is the maximum reverse leakage current for the 1N4107?
The 1N4107 specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 10.4 V (80% of nominal VZ), measured at 25 °C. This ultra-low leakage ensures minimal error current in high-impedance reference circuits and maintains accuracy in battery-powered or low-power monitoring applications.
Can the 1N4107 be used in surface-mount designs?
No-the 1N4107 is exclusively offered in the axial-leaded DO-35 (DO-204AH) through-hole package. For surface-mount equivalents, Microsemi offers the 1N4107UR-1 in DO-213AA and 1PMT4107 in DO-216 packages, which share identical electrical specifications but differ in mounting form factor and qualification level.
What is the thermal resistance of the 1N4107?
The 1N4107 has a thermal resistance of 250 °C/W junction-to-lead (RθJL) when mounted with 3/8″ (10 mm) lead length from body, and 300 °C/W junction-to-ambient (RθJA) on FR4 board with specified copper pad geometry. These values govern thermal derating curves and define safe operating area under sustained power dissipation.
