Product details
Overview
JANTXV1N5194UR/TR from Microsemi is a hermetically sealed, metallurgically bonded switching diode rated for 70 V DC reverse voltage, 200 mA maximum operating current, and 500 mW total power dissipation at 25°C, with 1.0 V max forward voltage at 100 mA and 25°C - used in high-reliability military power supply clamping and signal routing circuits.
For engineers reviewing the JANTXV1N5194UR/TR datasheet, JANTXV1N5194UR/TR pinout, JANTXV1N5194UR/TR application, or JANTXV1N5194UR/TR equivalent, key selection criteria include MIL-PRF-19500/118 qualification level (JANTXV), DO-213AA glass package dimensions, cathode band polarity marking, 70°C/W thermal impedance, and -65°C to +175°C operating/storage temperature range.
Technical Context
This diode employs double plug construction and metallurgical bonding to achieve robust transient surge handling (2 A sine, 8.3 ms) and stable leakage performance - IR ≤ 0.025 µA at 70 V and 25°C, rising to ≤ 5.0 µA at 150°C.
Designed for high-temperature and radiation-tolerant environments, it maintains electrical integrity across its full -65°C to +175°C range, with thermal impedance limited to 70°C/W from junction to case, enabling reliable operation in conduction-cooled military avionics and downhole instrumentation.
Key Specifications

Use Value: Low VF (≤1.0 V) minimizes forward-path loss while maintaining 70 V standoff for antenna port protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5193UR/TR | Lower VRWM (50 V), same package and surge rating | Suitable only for ≤50 V systems; not interchangeable in 70 V designs | Select only when system reverse voltage is confirmed ≤50 V and JANTXV1N5194UR/TR is unavailable |
| JANTXV1N5195UR/TR | Higher VRWM (100 V), identical thermal and current ratings | Accepts wider input transients but may exhibit slightly higher VF due to wider depletion region | Preferred where 100 V standoff is required; verify VF impact on forward conduction loss |
Compared with JANTXV1N5193UR/TR and JANTXV1N5195UR/TR, the JANTXV1N5194UR/TR provides optimal balance of 70 V standoff, low VF, and MIL-qualified reliability for mid-voltage military power and signal conditioning - avoiding overdesign or under-specification.

FAQ
What is the qualified reliability level of JANTXV1N5194UR/TR?
JANTXV1N5194UR/TR is qualified to MIL-PRF-19500/118 Class JANTXV, which includes rigorous screening for burn-in, temperature cycling, and parameter verification - ensuring suitability for high-reliability military and aerospace applications where failure is not an option. The JANTXV1N5194UR/TR meets all requirements specified in LDS-0032 Rev. 1.
Does JANTXV1N5194UR/TR have a defined cathode marking?
Yes, the JANTXV1N5194UR/TR uses a visible axial band on the glass envelope to identify the cathode terminal, consistent with DO-213AA mechanical outline standards. This marking is critical for correct orientation in clamping and rectifier configurations, and is verified per MIL-PRF-19500/118 visual inspection requirements.
What is the thermal impedance of JANTXV1N5194UR/TR, and how does it affect layout?
The JANTXV1N5194UR/TR has a maximum junction-to-case thermal impedance (ZθJX) of 70°C/W, measured under standard test conditions. This value informs heatsinking decisions - for sustained 200 mA operation above 85°C ambient, designers should minimize lead thermal resistance and avoid excessive copper removal near the device body. The JANTXV1N5194UR/TR does not require external heatsinks in typical pulse-duty applications.
Can JANTXV1N5194UR/TR be used in place of commercial-grade 1N5194 diodes?
No - the JANTXV1N5194UR/TR is not a drop-in replacement for commercial 1N5194 variants. It features hermetic glass packaging, MIL-qualified screening, tighter IR limits, and extended temperature capability (-65°C to +175°C), whereas commercial versions use plastic packages and lack military screening. Substitution requires full requalification per application requirements. The JANTXV1N5194UR/TR must be selected explicitly for its qualified attributes.
What is the maximum surge current rating for JANTXV1N5194UR/TR, and under what waveform is it specified?
The JANTXV1N5194UR/TR is rated for 2 A peak surge current under a sine wave with 8.3 ms duration (equivalent to one half-cycle of 60 Hz AC), as defined in MIL-PRF-19500/118. This rating applies to short-duration transients such as inductive kickback or load dump events, and is validated through standardized surge testing per the specification. The JANTXV1N5194UR/TR maintains parametric integrity after this stress.
