Product details
Overview
JANTXV1N4113C-1 from Microsemi is a 500 mW, 19.0 V ±2% metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JANTXV1N4113C-1 datasheet, JANTXV1N4113C-1 pinout, JANTXV1N4113C-1 application, or JANTXV1N4113C-1 equivalent, key selection factors include its 19.0 V nominal Zener voltage at 250 mA test current, 150 Ω dynamic impedance, 0.05 µA maximum reverse leakage at 14.5 V, and -65 °C to +175 °C operating junction temperature range.
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable DC voltage across wide current (250 mA IZT) and temperature (-65 °C to +175 °C TJ) ranges. Its internal metallurgical bond ensures mechanical robustness and low noise density (1 µV/√Hz typical at low voltages), critical for precision analog references.
Designed for military-grade reliability, JANTXV1N4113C-1 meets MIL-PRF-19500/435 requirements with hermetically sealed DO-35 glass package, cathode band polarity marking, and RoHS-compliant plating (commercial versions only). It exhibits a +0.090 %/°C temperature coefficient and minimal capacitance per Figure 3.

FAQ
What is the nominal Zener voltage and test current for JANTXV1N4113C-1?
JANTXV1N4113C-1 has a nominal Zener voltage of 19.0 V measured at a Zener test current (IZT) of 250 mA. This value is specified under thermal equilibrium at 25 °C ambient and reflects the device's regulation point in reverse breakdown operation. The ±2% tolerance ensures tight voltage control without external trimming.
Is JANTXV1N4113C-1 suitable for high-temperature applications?
Yes, JANTXV1N4113C-1 is rated for junction temperatures from -65 °C to +175 °C and is qualified per MIL-PRF-19500/435 JANTXV level. Its metallurgically bonded construction and hermetic DO-35 package ensure stable electrical parameters and mechanical integrity in sustained high-temperature environments such as downhole tools and engine-mounted avionics.
What is the maximum reverse leakage current for JANTXV1N4113C-1?
JANTXV1N4113C-1 specifies a maximum reverse leakage current (IR) of 0.05 µA at VR = 14.5 V. This ultra-low leakage supports low-power standby modes and minimizes error in precision reference circuits where even nanoamp-level currents affect accuracy.
Does JANTXV1N4113C-1 have radiation hardness certification?
Yes, JANTXV1N4113C-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its construction and qualification per MIL-PRF-19500/435 support operation in total ionizing dose (TID) environments typical of low-earth orbit and nuclear instrumentation applications.
What packaging options are available for JANTXV1N4113C-1?
JANTXV1N4113C-1 is supplied in the axial-leaded DO-35 (DO-204AH) glass package. Tape-and-reel (TR) packaging is available upon request with "TR" suffix added to the part number. Surface-mount variants like 1N4113US-1 exist but are distinct orderables-not drop-in replacements for JANTXV1N4113C-1.
