Product details
Overview
JANTX1N5807URS/TR from Microsemi is a military-qualified ultrafast recovery glass rectifier diode in URS (one square + one round end cap) MELF package, rated for 50 V working peak reverse voltage, 6.0 A average rectified current at 75 °C, and 30 ns reverse recovery time-used in high-reliability switching power supplies and radiation-hardened systems.
For engineers reviewing the JANTX1N5807URS/TR datasheet, JANTX1N5807URS/TR pinout, JANTX1N5807URS/TR application, or JANTX1N5807URS/TR equivalent, key selection criteria include MIL-PRF-19500/477 JANTX qualification, void-less hermetic glass construction, Category 1 metallurgical bond, and thermal resistance of 6.5 °C/W junction-to-end cap.
Technical Context
This device operates as a unidirectional silicon power rectifier with controlled avalanche capability and inherent radiation hardness per MicroNote 050. Its ultrafast 30 ns recovery time and low forward voltage (0.875 V @ 4 A) support high-frequency switching efficiency in hardened DC–DC converters.
The URS package features tungsten slugs and tin/lead terminations, enabling stable thermal performance under surge conditions (125 A IFSM) and operation across –65 °C to +175 °C junction temperature range, with cathode polarity marked by a blue band.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 50 V - Maximum sustainable reverse voltage without breakdown during normal operation |
| IO1 @ TL = 75 °C | 6.0 A - Continuous average forward current with 3/8″ lead length and end-cap temperature control |
| trr | 30 ns - Time to recover blocking capability after forward conduction, critical for >100 kHz SMPS |
| VFM @ 4 A | 0.875 V - Forward voltage drop determining conduction loss and thermal load at rated current |
| RθJEC | 6.5 °C/W - Junction-to-end-cap thermal resistance enabling direct heatsinking via end caps |
| IFSM | 125 A - Non-repetitive surge current handling for line transients and startup events |
| TJ/TSTG | –65 °C to +175 °C - Full military temperature range supporting space and avionics deployment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N5807US | Same die, US package (two square end caps); identical electrical specs but different mechanical mounting geometry | Requires PCB pad layout change due to dual-square footprint vs. URS asymmetric geometry | Select US for standard MELF-compatible layouts; choose URS when asymmetric thermal path or mechanical retention is needed |
| JANTXV1N5807URS/TR | Identical URS package and electrical specs, but qualified to higher JANTXV level per MIL-PRF-19500/477 with extended screening | Suitable for mission-critical flight hardware where burn-in, life test, and radiation lot acceptance are mandatory | Use JANTXV version when full JANTXV screening (including 100% thermal cycling and 1000-hour life test) is required by program spec |
Compared with JANTX1N5807US and JANTXV1N5807URS/TR, the JANTX1N5807URS/TR offers the same ultrafast 30 ns recovery and 50 V VRWM in a mechanically distinct URS form factor, balancing JANTX reliability with optimized thermal mounting-making it ideal for programs needing verified military qualification without full JANTXV cost or footprint constraints.

FAQ
What does "URS" signify in JANTX1N5807URS/TR?
The "URS" suffix in JANTX1N5807URS/TR denotes the package configuration: one square end cap and one round end cap in a hermetically sealed void-less glass MELF-style body. This asymmetric geometry provides differentiated thermal and mechanical mounting characteristics versus the "US" (dual square) variant, and is explicitly defined in Microsemi's nomenclature guide for MIL-PRF-19500/477 qualified devices.
Is JANTX1N5807URS/TR RoHS compliant?
No, JANTX1N5807URS/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e3 marking) are available only for commercial-grade variants-not for JANTX-level military-qualified parts like JANTX1N5807URS/TR, which retain tin/lead terminations to meet MIL-PRF-19500/477 solderability and reliability requirements.
What is the maximum junction temperature for JANTX1N5807URS/TR?
The maximum junction temperature for JANTX1N5807URS/TR is +175 °C, and the storage temperature range is identical (–65 °C to +175 °C). This rating is validated under MIL-PRF-19500/477 screening and applies across all JANTX qualification levels; derating curves for IO1 and IO2 are provided in the datasheet based on end-cap or ambient temperature limits.
How does the Category 1 metallurgical bond affect JANTX1N5807URS/TR reliability?
The Category 1 metallurgical bond in JANTX1N5807URS/TR ensures robust interfacial integrity between the silicon die and tungsten slug under thermal cycling, mechanical shock, and sustained high-current operation. This bond type is mandated for JANTX and higher reliability levels and directly contributes to the device's ability to maintain parameter stability and avoid delamination in mission-critical avionics and space applications.
Can JANTX1N5807URS/TR replace JANTX1N5807US in an existing design?
JANTX1N5807URS/TR cannot be used as a drop-in replacement for JANTX1N5807US without PCB layout modification. Although both share identical electrical specifications and JANTX qualification, the URS package (square + round end cap) requires different pad geometry than the US package (two square end caps), as confirmed by Microsemi's package dimension drawings and assembly guidelines.
