Product details
Overview
JANS1N3595AUR-1/TR from Microsemi is a hermetically sealed, metallurgically bonded switching diode in DO-213AA glass package, rated for 125V DC reverse voltage, 150mA operating current, and 500mW power dissipation, with 3.0µs maximum reverse recovery time - used in high-reliability military timing, pulse shaping, and clamping circuits.
For engineers reviewing the JANS1N3595AUR-1/TR datasheet, JANS1N3595AUR-1/TR pinout, JANS1N3595AUR-1/TR application, or JANS1N3595AUR-1/TR equivalent, key selection criteria include MIL-PRF-19500/241 qualification, -65°C to +175°C operating temperature range, 4A 1µs surge capability, and DO-213AA hermetic glass packaging for radiation-tolerant and high-stability environments.
Technical Context
This diode employs double-plug construction with copper-clad steel leads and tin/lead finish, enabling stable operation under extreme thermal cycling and mechanical stress. Its metallurgical bonding and hermetic sealing meet MIL-PRF-19500/241 Level JANTXV requirements for space and defense electronics.
With 8.0pF maximum capacitance at 0V and 3.0µs max TRR at IF=10mA/VR=35V, it supports fast switching in pulse generators and RF detector stages where low charge storage and minimal recovery lag are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DC Reverse Voltage (VRWM) | 125V - defines maximum continuous blocking voltage before leakage or breakdown in clamp or protection circuits |
| Operating Current (IF) | 150mA at TA=+25°C - sets usable forward conduction limit for sustained signal routing or biasing |
| Reverse Recovery Time (TRR) | ≤3.0µs at IF=10mA, VR=35V - ensures minimal switching distortion in >100kHz pulse applications |
| Surge Current (1µs) | 4A - enables transient overvoltage handling without failure in ESD or inductive kick suppression |
| Operating Temperature Range | -65°C to +175°C - supports deployment in aerospace avionics, missile guidance, and downhole oil/gas electronics |
| Thermal Impedance (ZθJX) | ≤70°C/W - determines junction-to-external-heat-sink temperature rise under 500mW dissipation |
Pinout & Package
Hermetically sealed DO-213AA glass package with axial leads; cathode identified by band on glass body; lead material is copper-clad steel with tin/lead finish; polarity must be observed during PCB placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node in rectifier or clamp configuration; requires proper thermal relief in high-current traces |
| Cathode | Forward current exit / reverse blocking terminal | Banded end - ties to higher-potential node; critical for correct polarity in protection circuits and logic-level translation |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/241 Qualified | JANTXV level - guarantees screening, testing, and traceability for Class H (space) and Class K (military) applications |
| Hermetic Glass Encapsulation | DO-213AA outline - prevents moisture ingress and outgassing, preserving long-term parameter stability in vacuum or humid environments |
| Double Plug Construction | Enhanced mechanical bond integrity - resists lead pull-out and thermal fatigue during rework or thermal cycling |
| Metallurgical Bonding | Low-resistance die attachment - minimizes forward voltage drift and improves thermal transfer from junction to leads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N3595AUR-1 | Same die, identical DO-213AA package, but screened to JANTXV level with full MIL-PRF-19500/241 test flow including burn-in and life test | Required for Class H space programs where lot traceability and extended reliability data are mandated | Select JANTXV1N3595AUR-1 when mission-critical radiation tolerance and 100% lot acceptance testing are required |
| 1N3595AUR-1/TR | Commercial-grade version; same electrical specs but no MIL screening; not qualified to MIL-PRF-19500 | Suitable for industrial prototypes or non-mission-critical test fixtures where cost and lead time outweigh qualification needs | Choose 1N3595AUR-1/TR only for bench validation or non-certified systems with relaxed reliability requirements |
Compared with JANS1N3595AUR-1/TR, JANTXV1N3595AUR-1 adds full JANTXV screening for space-grade assurance, while 1N3595AUR-1/TR omits MIL qualification entirely - making the JANS variant the only option meeting JAN-level procurement specifications for defense prime contracts.

FAQ
What is the maximum reverse recovery time (TRR) specification for JANS1N3595AUR-1/TR?
The JANS1N3595AUR-1/TR has a maximum reverse recovery time of 3.0µs when tested at IF = 10mA and VR = 35V, per LDS-0073 Rev. 2. This value is guaranteed for all units in the JANS lot and reflects its suitability for high-speed pulse applications such as radar timing and digital signal clamping where fast turn-off is essential. The TRR is measured under standardized MIL conditions and remains stable across the full -65°C to +175°C operating range.
Does JANS1N3595AUR-1/TR meet MIL-PRF-19500/241 requirements?
Yes, JANS1N3595AUR-1/TR is fully qualified to MIL-PRF-19500/241, Level JAN, with documentation in LDS-0073 Rev. 2. It undergoes rigorous screening including temperature cycling, steady-state life test, and parameter verification per the specification. This qualification confirms its readiness for use in defense procurement programs requiring JAN-level traceability, reliability, and environmental robustness - distinct from commercial or JANTX-grade variants.
What is the package type and marking convention for JANS1N3595AUR-1/TR?
JANS1N3595AUR-1/TR uses the DO-213AA hermetically sealed glass package with axial leads. The cathode is marked by a visible band on the glass body. The "UR-1" suffix denotes the DO-213AA outline, and "TR" indicates tape-and-reel packaging. No alphanumeric date or lot code appears on the device itself - full traceability is maintained via certificate of compliance and lot-specific test data provided with shipment of JANS1N3595AUR-1/TR.
What is the thermal impedance (ZθJX) of JANS1N3595AUR-1/TR and how does it affect layout?
JANS1N3595AUR-1/TR has a maximum thermal impedance of 70°C/W from junction to external heat sink (ZθJX), as specified in LDS-0073 Rev. 2. This means that at 500mW dissipation, the junction temperature rises up to 35°C above the external mounting surface temperature. For reliable operation at +175°C ambient, PCB land patterns must provide adequate copper area and thermal vias to maintain the external surface below +140°C - especially critical in sealed enclosures or high-power-density avionics assemblies using JANS1N3595AUR-1/TR.
How does the 4A 1µs surge rating of JANS1N3595AUR-1/TR impact system-level protection design?
The 4A surge current rating at 1µs for JANS1N3595AUR-1/TR allows it to safely absorb short-duration energy spikes from inductive loads or ESD events without degradation. This capability is validated per MIL-STD-750 Method 2074 and enables direct integration into solenoid driver flyback paths or MIL-STD-461 RS103 input filters. Unlike standard diodes, JANS1N3595AUR-1/TR maintains parameter integrity after repeated 4A surges - a key requirement in naval and ground vehicle systems where JANS1N3595AUR-1/TR serves as primary transient suppression.
