Product details
Overview
JAN1N3595AUR-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 JAN1N3595AUR-1/TR datasheet, JAN1N3595AUR-1/TR pinout, JAN1N3595AUR-1/TR application, or JAN1N3595AUR-1/TR equivalent, key selection criteria include MIL-PRF-19500/241 qualification, -65°C to +175°C operating range, 8.0pF capacitance at 0V, surge current capability (4A/1µs), and cathode-banded polarity marking.
Technical Context
This diode employs double-plug construction and metallurgical bonding to achieve stable junction characteristics across extreme temperatures. Its hermetic DO-213AA glass package ensures long-term reliability under thermal cycling and humidity exposure per MIL-PRF-19500/241 Level JANTXV.
Designed for fast switching, it delivers ≤3.0µs reverse recovery time at IF = 10mA and VR = 35V, with forward voltage ranging from 0.52V (1mA) to 0.83V (200mA) at 25°C. Thermal impedance is specified at ≤70°C/W from junction to case.
Key Specifications

|---|---|
| DC Reverse Voltage (VRWM) | 125V - supports clamping and protection in 100V-class signal paths without breakdown |
| Forward Current (IF) | 150mA at TA = +25°C - defines continuous conduction limit in low-power switching nodes |
| Reverse Recovery Time (TRR) | ≤3.0µs at IF = 10mA, VR = 35V - enables use in >100kHz pulse applications with minimal switching loss |
| Junction-to-Case Thermal Impedance | ≤70°C/W - limits temperature rise under 500mW dissipation in compact layouts |
| Capacitance at 0V | ≤8.0pF - preserves signal integrity in RF and high-speed digital edge-detection circuits |
| Operating Temperature Range | -65°C to +175°C - qualified for aerospace, downhole, and engine-control environments |

FAQ
What is the qualified reliability level of JAN1N3595AUR-1/TR?
JAN1N3595AUR-1/TR is qualified per MIL-PRF-19500/241 at JAN level, meeting baseline military screening requirements including temperature cycling, steady-state life test, and parametric verification. It is not JANTX or JANTXV, which require additional tests like burn-in and lot acceptance testing. The JAN1N3595AUR-1/TR datasheet LDS-0073 Rev. 2 confirms this qualification scope.
Does JAN1N3595AUR-1/TR have a defined cathode marking?
Yes, JAN1N3595AUR-1/TR uses a single black band on the glass body to identify the cathode terminal, consistent with DO-213AA industry convention. This marking is visible under standard optical inspection and supports automated optical alignment during pick-and-place. The polarity is documented in the "DESIGN DATA" section of the LDS-0073 datasheet.
What is the maximum reverse recovery time for JAN1N3595AUR-1/TR?
The maximum reverse recovery time (TRR) for JAN1N3595AUR-1/TR is 3.0µs, measured at IF = 10mA and VR = 35V with a 50% reference level, per AC ELECTRICAL CHARACTERISTICS table on page 1 of LDS-0073 Rev. 2. This value is guaranteed across the full -65°C to +175°C operating range and applies to all units within specification.
Can JAN1N3595AUR-1/TR be used in surface-mount assemblies?
No, JAN1N3595AUR-1/TR is an axial-leaded DO-213AA glass device and is intended for through-hole mounting only. Its lead configuration and glass body geometry do not support reflow-compatible SMT processes. For surface-mount equivalents, consider Microsemi's MLL3595A variant, which shares the same die but uses a molded plastic SOD-123FL package.
What is the thermal impedance of JAN1N3595AUR-1/TR?
The junction-to-case thermal impedance (ZθJX) of JAN1N3595AUR-1/TR is specified at ≤70°C/W maximum, per the DESIGN DATA section of LDS-0073 Rev. 2. This value assumes direct thermal contact between the glass body and PCB copper pour or heatsink surface, and is used to calculate worst-case junction temperature under 500mW dissipation.
