Product details

Overview

JANTX1N4111D-1 from Microsemi is a 1% tolerance, 17.0 V Zener voltage regulator diode in DO-35 glass axial package, rated for 500 mW power dissipation, with 100 Ω dynamic impedance at 250 mA test current and +0.090 %/°C temperature coefficient - used for precision voltage reference and regulation in military-grade power supply feedback loops.

For engineers reviewing the JANTX1N4111D-1 datasheet, JANTX1N4111D-1 pinout, JANTX1N4111D-1 application, or JANTX1N4111D-1 equivalent, key selection criteria include Zener voltage tolerance (1%), junction temperature range (–65 to +175 °C), noise density (1 µV/√Hz), RoHS compliance status, and MIL-PRF-19500/435 qualification level (JANTX).

Technical Context

This device operates as a reverse-biased Zener regulator with metallurgically bonded construction for high-reliability operation. It delivers stable 17.0 V regulation at I_ZT = 250 mA, exhibits low dynamic impedance (100 Ω) and minimal capacitance (typ. <1.5 pF), and maintains performance across –65 to +175 °C junction temperature.

Its 1% voltage tolerance (denoted by "D" suffix), +0.090 %/°C temperature coefficient, and 40 µV/√Hz max noise density above 6.8 V support precision analog references in avionics and space-grade power conditioning where long-term stability and radiation hardness are required.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	17.0 V ±1% at 250 mA - ensures tight regulation in feedback networks requiring sub-170 mV error budget.
Power Dissipation	500 mW @ T_L = 25 °C - supports continuous operation in compact through-hole designs with 3/8″ lead length.
Dynamic Impedance Z_ZT	100 Ω @ 250 mA - minimizes output voltage shift under load transients in regulated DC supplies.
Temp Coefficient α_VZ	+0.090 %/°C - enables predictable drift compensation in wide-temperature military environments.
Noise Density ND	1 µV/√Hz @ I_ZT - critical for low-noise reference applications such as ADC voltage references and sensor excitation.
Junction Temp Range	–65 to +175 °C - qualified for extreme-environment deployment including aerospace and downhole electronics.
Reverse Leakage I_R	0.05 µA @ 13.0 V - guarantees negligible current draw in high-impedance bias networks.

Pinout & Package

DO-35 (DO-204AH) hermetically sealed axial-leaded glass package; cathode indicated by band; banded end is anode when used in forward conduction, but functions as cathode (positive terminal) during Zener regulation.

Pin/Terminal	Circuit Role	Design Meaning
Anode (banded end)	Zener cathode connection	Connected to regulated output node; must be held at higher potential than cathode for breakdown operation.
Cathode (unbanded end)	Zener anode connection	Connected to circuit ground or lower-potential rail; completes reverse-bias path for regulation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
JANTXV1N4111D-1	Higher qualification level (JANTXV vs JANTX); tighter screening, enhanced burn-in, and extended life testing per MIL-PRF-19500/435.	Required for space-flight-critical subsystems where failure probability must be <1×10⁻⁶ per 10,000 hrs.	Select when mission-critical reliability outweighs cost premium and longer lead times.
1N4111UR-1	Same electrical specs but in DO-213AA surface-mount package; no axial leads; RoHS-compliant matte-tin plating.	Used where PCB real estate is constrained and automated SMT assembly is mandatory.	Choose for new designs targeting high-volume production with reflow compatibility and smaller footprint.

Compared with JANTX1N4111D-1, JANTXV1N4111D-1 adds process-level reliability assurance for zero-defect requirements, while 1N4111UR-1 trades axial mounting for SMT compatibility - neither is pin-compatible due to differing packages, but all three share identical Zener characteristics and thermal derating behavior.

FAQ

What is the Zener voltage tolerance of JANTX1N4111D-1?

JANTX1N4111D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number. This means its nominal 17.0 V Zener voltage is guaranteed between 16.83 V and 17.17 V at 250 mA test current and 25 °C ambient, enabling high-accuracy regulation without external trimming.

Is JANTX1N4111D-1 RoHS compliant?

JANTX1N4111D-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only on commercial-grade parts, not on JANTX-qualified devices. JANTX1N4111D-1 uses traditional tin-lead plating to meet MIL-STD-750 solderability requirements.

What is the maximum Zener current I_ZM for JANTX1N4111D-1?

The maximum Zener current I_ZM for JANTX1N4111D-1 is 13.0 mA, calculated from its 500 mW power rating and 17.0 V Zener voltage (I_ZM = P_M(AV)/V_Z). Derating begins linearly at 50 °C lead temperature, reaching zero at 175 °C.

Does JANTX1N4111D-1 have radiation hardness?

Yes, JANTX1N4111D-1 is inherently radiation hard, as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction provides resistance to total ionizing dose (TID) and single-event effects, making it suitable for low-earth orbit and nuclear instrumentation applications without additional shielding.

What package type does JANTX1N4111D-1 use?

JANTX1N4111D-1 uses the DO-35 (also designated DO-204AH) hermetically sealed axial-leaded glass package. Dimensions comply with MIL-PRF-19500/435, with body diameter 1.42–2.29 mm and overall length 3.56–5.08 mm, and polarity marked by a cathode band.
