Product details
Overview
1N3595AUR-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 3.0µs maximum reverse recovery time at 10mA/35V, used in high-reliability military timing and pulse shaping circuits.
For engineers reviewing the 1N3595AUR-1/TR datasheet, 1N3595AUR-1/TR pinout, 1N3595AUR-1/TR application, or 1N3595AUR-1/TR equivalent, key selection criteria include MIL-PRF-19500/241 qualification, -65°C to +175°C operating range, 500mW power dissipation, and low-junction-capacitance (≤8.0pF) for fast-switching integrity in harsh-environment analog signal paths.
Technical Context
This diode employs double-plug construction with copper-clad steel leads and tin/lead finish, enabling stable junction behavior under thermal cycling. Its metallurgical bonding and hermetic glass seal meet MIL-PRF-19500/241 Level JANTXV requirements for radiation-hardened and high-vacuum applications.
The device exhibits low forward voltage (0.52–1.00V across 1–200mA), sub-2µA reverse leakage at 125V, and tight TRR distribution (≤3.0µs), making it suitable for precision clamping and fast edge regeneration where parametric consistency across temperature extremes is critical.
Key Specifications

|---|---|
| DC Reverse Voltage (VRWM) | 125V - Maximum continuous blocking voltage before significant leakage or breakdown |
| Forward Voltage (VF) | 0.52V min / 1.00V max @ 1–200mA - Defines conduction loss and thermal rise in series-switched paths |
| Reverse Recovery Time (TRR) | ≤3.0µs @ IF=10mA, VR=35V - Critical for minimizing switching losses in >100kHz pulse circuits |
| Junction Capacitance (CJ) | ≤8.0pF @ 0V - Enables minimal signal distortion in RF coupling and high-speed sampling hold stages |
| Operating Temperature Range | -65°C to +175°C - Supports deployment in aerospace avionics, downhole tools, and engine-mounted control modules |
| Total Power Dissipation | 500mW - Sets maximum steady-state I²R heating limit at ambient, constrained by 70°C/W thermal impedance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N3595UR-1/TR | No JANTXV screening; rated for same VRWM, TRR, and package but lacks MIL-PRF-19500/241 Level JANTXV test documentation | Suitable for commercial-grade industrial controls where full military screening is not mandated | Select when cost sensitivity outweighs need for certified radiation tolerance and extended temperature validation |
| 1N4148WS-7-F | Plastic SOD-323 package; 100V VRWM; 4.0ns TRR; not hermetically sealed or MIL-qualified | Used in consumer electronics and non-safety-critical digital logic clamping | Choose only for board-space-constrained designs requiring ultra-fast switching below 100V, with no environmental ruggedness requirement |
Compared with 1N3595AUR-1/TR, the 1N3595UR-1/TR offers identical electrical specs but reduced qualification rigor, while the 1N4148WS-7-F trades hermeticity and temperature range for speed and footprint-making the 1N3595AUR-1/TR irreplaceable where long-term reliability under thermal stress and radiation exposure is non-negotiable.

FAQ
What is the maximum reverse recovery time specified for the 1N3595AUR-1/TR?
The 1N3595AUR-1/TR has a maximum reverse recovery time (TRR) of 3.0µs when tested at IF = 10mA and VR = 35V per LDS-0073 Rev. 2. This value is guaranteed across the full -65°C to +175°C operating range and is integral to its use in fast-switching pulse-shaping applications where edge fidelity must be preserved.
Is the 1N3595AUR-1/TR hermetically sealed, and what standard does it meet?
Yes, the 1N3595AUR-1/TR uses a hermetically sealed glass package conforming to MIL-PRF-19500/241, specifically qualified to JANTXV level. Its DO-213AA outline, metallurgical bonding, and double-plug construction ensure zero moisture ingress and long-term parameter stability required in aerospace and defense deployments.
What is the forward voltage range of the 1N3595AUR-1/TR at 10mA?
At 10mA forward current and 25°C ambient, the 1N3595AUR-1/TR exhibits a forward voltage between 0.65V (minimum) and 0.80V (maximum), as specified in the DC Electrical Characteristics table of LDS-0073 Rev. 2. This tight VF window supports predictable power loss modeling in precision analog switch designs.
Does the 1N3595AUR-1/TR have a defined junction capacitance, and what is its maximum value?
Yes, the 1N3595AUR-1/TR has a maximum junction capacitance (CJ) of 8.0pF measured at 0V reverse bias and 25°C. This low capacitance enables minimal loading in high-frequency coupling, sampling, and RF detector circuits where signal integrity depends on controlled reactive impedance.
What is the thermal impedance (ZθJX) of the 1N3595AUR-1/TR, and how does it affect power handling?
The 1N3595AUR-1/TR has a maximum thermal impedance (ZθJX) of 70°C/W, meaning each watt of dissipated power raises the junction temperature by up to 70°C above the mounting surface. At its 500mW power rating, this limits allowable ambient rise to ~35°C without heatsinking-critical for compact, sealed enclosure designs.
