Product details
Overview
JAN1N4114C-1 from Microsemi is a 500 mW, 20 V ±2% tolerance, metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JAN1N4114C-1 datasheet, JAN1N4114C-1 pinout, JAN1N4114C-1 application, or JAN1N4114C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), and JANS-qualified thermal stability up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 20.0 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.090 %/°C and low dynamic impedance optimized for stable reference generation under varying load and temperature conditions.
Its hermetically sealed DO-35 glass package enables operation across -65 °C to +175 °C, with metallurgical bonding ensuring mechanical robustness and long-term parameter stability required in military avionics and space-grade power supplies.

FAQ
What is the Zener voltage tolerance for JAN1N4114C-1?
JAN1N4114C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This corresponds to a nominal 20.0 V Zener voltage ranging from 19.6 V to 20.4 V at 250 mA test current and 25 °C ambient, meeting MIL-PRF-19500/435 requirements for precision regulation in high-reliability circuits.
Is JAN1N4114C-1 RoHS compliant?
No, JAN1N4114C-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4114C-1e3); JAN-level parts retain traditional tin-lead plating per MIL-STD-750 to ensure solderability and reliability under extreme thermal cycling, as required for military and aerospace applications.
What is the maximum Zener current IZM for JAN1N4114C-1?
The maximum Zener current IZM for JAN1N4114C-1 is 40 mA, derived from its 500 mW power rating and 20 V nominal Zener voltage (P = V × I → I = 0.5 W / 20 V = 25 mA typical, with margin up to 40 mA per absolute maximum ratings table). Operation above this risks thermal runaway or parameter shift.
How does the temperature coefficient affect JAN1N4114C-1 in real-world operation?
JAN1N4114C-1 has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 18 mV per 10 °C rise above 25 °C. This predictable positive drift allows designers to compensate in feedback networks or select complementary components to achieve net-zero thermal drift in precision references.
Can JAN1N4114C-1 be used in surface-mount designs?
JAN1N4114C-1 itself is axial-leaded DO-35 and not suitable for SMT. However, Microsemi offers the functionally identical 1N4114US-1 in DO-213AA surface-mount package. That variant maintains the same 20 V ±2% Zener voltage and noise performance but requires requalification for thermal and mechanical stress in reflow-soldered assemblies.
