Product details
Overview
JANS1N4131-1/TR from Microsemi is a 75 V, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers ±5% Zener voltage tolerance at 250 mA test current, exhibits 700 Ω dynamic impedance, and maintains stable regulation across -65 °C to +175 °C junction temperature range.
For engineers reviewing the JANS1N4131-1/TR datasheet, JANS1N4131-1/TR pinout, JANS1N4131-1/TR application, or JANS1N4131-1/TR equivalent, key selection criteria include its radiation-hardened construction, low noise density (1 µV/√Hz), hermetic glass sealing, and compliance with military reliability standards for critical voltage reference and regulation tasks.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased mode, with cathode band indicating polarity. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, while the DO-35 glass package provides hermeticity and low parasitic capacitance (typical <1.5 pF at 75 V).
The JANS1N4131-1/TR is characterized at 250 mA Zener test current (IZT), with maximum reverse leakage of 10 nA at 60 V (VR), temperature coefficient of +0.100 %/°C, and noise density of 1 µV/√Hz - consistent with low-voltage Zener behavior below 100 V per Microsemi MicroNote 050.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4131-1 | Same electrical specs but qualified to JANTXV level (lower screening rigor than JANS); not radiation-hardness verified | Suitable for ground-test equipment and non-flight avionics where TID tolerance is not required | Select when cost and lead time are prioritized over space qualification and radiation assurance |
| 1N4131US-1 | Same Zener voltage and DO-35 package, but commercial-grade (non-mil-qualified); RoHS-compliant matte-tin plating | Applicable only in benign industrial environments with no ESD, shock, or radiation constraints | Choose for prototyping or commercial subsystems where MIL-PRF-19500 compliance is unnecessary |
Compared with JANS1N4131-1/TR, JANTXV1N4131-1 offers faster procurement and lower cost but lacks radiation hardness validation and full JANS screening; 1N4131US-1 provides RoHS compliance and shorter lead times but excludes hermeticity verification and temperature cycling data required for flight hardware.

FAQ
What is the Zener voltage tolerance for JANS1N4131-1/TR?
JANS1N4131-1/TR has a nominal Zener voltage of 75 V with a ±5% tolerance, measured at 250 mA test current (IZT) under thermal equilibrium at 25 °C. This tolerance is inherent to the JEDEC-registered 1N4099–1N4135 series and applies across all reliability levels including JANS.
Is JANS1N4131-1/TR radiation hardened?
Yes, JANS1N4131-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 glass package provide proven tolerance to total ionizing dose (TID), making it suitable for low-earth orbit and other radiation-exposed environments.
What does the "TR" suffix mean in JANS1N4131-1/TR?
The "TR" suffix in JANS1N4131-1/TR indicates tape-and-reel packaging per EIA-296 standard. This format supports automated placement in high-volume production and is available upon factory consultation for specified quantities.
Can JANS1N4131-1/TR be used in surface-mount designs?
No - JANS1N4131-1/TR uses the axial-leaded DO-35 (DO-204AH) package and is not surface-mount compatible. For SMT equivalents, consider Microsemi's 1N4131UR-1 in DO-213AA or 1PMT4131 in DO-216, which share identical electrical specs but differ in qualification level and packaging.
What is the maximum reverse leakage current for JANS1N4131-1/TR?
JANS1N4131-1/TR specifies a maximum reverse leakage current (IR) of 10 nA at VR = 60 V and 25 °C. This ultra-low leakage ensures minimal power loss and high-impedance operation in precision reference and clamp applications.
