Product details
Overview
JANS1N5807URS/TR from Microsemi is a hermetically sealed ultrafast recovery glass rectifier diode rated for 6.0 A average forward current at 75 °C, 50 V working peak reverse voltage, and 30 ns reverse recovery time. It features void-less glass construction with Category 1 metallurgical bonds, RoHS-compliant terminations (commercial), and is qualified to MIL-PRF-19500/477 JANS level for space-grade reliability in high-reliability power conversion.
For engineers reviewing the JANS1N5807URS/TR datasheet, JANS1N5807URS/TR pinout, JANS1N5807URS/TR application, or JANS1N5807URS/TR equivalent, key selection criteria include ultrafast trr (30 ns), low VF (0.875 V @ 4 A), radiation-hardened capability per MicroNote 050, and hermetic MELF-style URS package with square+round end caps for thermal robustness in aerospace SMPS and avionics DC-DC stages.
Technical Context
This diode operates as a unidirectional power rectifier in switching topologies requiring fast turn-off to minimize switching losses and reduce EMI generation. Its 30 ns trr is measured under standardized conditions (IF = 1.0 A, IRM = 1.0 A, di/dt ≥ 100 A/µs), and its 6.5 °C/W junction-to-end-cap thermal resistance enables high-power dissipation in compact surface-mount layouts.
The URS package uses tungsten slugs and tin/lead (or matte tin for commercial) terminations over nickel-copper, with cathode polarity marked by a blue band. Its void-less glass seal meets MIL-PRF-19500/477 JANS requirements for operation across –65 °C to +175 °C junction temperature range and controlled avalanche performance up to 125 A surge current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 50 V - Maximum continuous reverse voltage before breakdown; sets safe operating limit in 48 V input SMPS designs. |
| IO1 @ TL=75 °C | 6.0 A - Sustained DC output current rating with end-cap heatsinking; defines usable current in thermally managed PCB layouts. |
| trr | 30 ns - Time to recover blocking state after forward conduction; critical for minimizing reverse recovery loss in >100 kHz converters. |
| VF @ 4 A | 0.875 V - Forward voltage drop at rated pulse current; directly determines conduction loss and thermal load in high-current paths. |
| RθJEC | 6.5 °C/W - Thermal resistance from junction to end cap; enables direct thermal coupling to metal-core or copper-pour PCBs for efficient heat extraction. |
| IFSM | 125 A - Non-repetitive surge current capability (8.3 ms); supports inrush tolerance in power-up sequences without failure. |
| CJ @ 10 V | 60 pF - Junction capacitance at 10 V reverse bias; influences high-frequency switching noise and snubber design requirements. |
Pinout & Package
The JANS1N5807URS/TR is housed in a hermetically sealed "URS" MELF-style package: one square end cap and one round end cap, void-less hard glass body with tungsten slugs, blue band indicating cathode polarity, and tin/lead terminations. Total weight is 539 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to positive side of AC source or switch node; must withstand 125 A surge and 50 V reverse during off-state. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5807URS/TR | Same electrical specs and URS package; qualified to JANTXV level (lower screening rigor than JANS, no radiation test). | Approved for airborne but not spaceflight; acceptable where total ionizing dose (TID) exposure is negligible. | Select when cost-sensitive aerospace programs require MIL-qualified ultrafast rectifiers without full JANS radiation validation. |
| Vishay VS-6EWH05FN-M3/45 | Commercial-grade 6 A, 50 V ultrafast diode in DO-214AC (SMA) package; trr = 35 ns, VF = 0.82 V @ 6 A, no hermetic seal or MIL qualification. | Not suitable for space or high-reliability mil-aero; limited to industrial/commercial SMPS with standard environmental requirements. | Choose only for cost-driven, non-mission-critical applications where hermeticity, radiation hardness, and JANS traceability are unnecessary. |
Compared with JANTXV1N5807URS/TR and VS-6EWH05FN-M3/45, the JANS1N5807URS/TR delivers unique value through full JANS-level screening, proven radiation hardness, and hermetic URS packaging-enabling deployment in satellite power systems where single-point failure is unacceptable.

FAQ
What is the maximum junction temperature rating for JANS1N5807URS/TR?
The JANS1N5807URS/TR has a specified junction and storage temperature range of –65 °C to +175 °C. This wide rating supports operation in extreme environments such as satellite thermal vacuums and jet engine bays. The 175 °C upper limit is critical for maintaining parameter stability and avoiding thermal runaway during high-current transients. Derating curves in the datasheet define safe current limits above 75 °C end-cap temperature.
Does JANS1N5807URS/TR have a RoHS-compliant version?
The JANS1N5807URS/TR itself is a JANS-level military part and uses traditional tin/lead terminations per MIL-PRF-19500/477 requirements. RoHS-compliant matte tin terminations are available only on commercial-grade versions (e.g., 1N5807URS/TR with blank or e3 suffix). For JANS applications, leaded terminations are mandatory to ensure solder joint reliability under thermal cycling and mechanical shock.
How does the URS package differ from US and axial-leaded variants of JANS1N5807?
The URS package of JANS1N5807URS/TR features one square and one round end cap, distinguishing it from the US variant (two square end caps) and axial-leaded versions. This geometry optimizes thermal contact area while maintaining compatibility with standard MELF pick-and-place tooling. The URS configuration also provides asymmetric mechanical anchoring, reducing stress-induced cracking during board flexure in high-vibration platforms like missiles and UAVs.
What is the significance of "Category 1 metallurgical bond" in JANS1N5807URS/TR?
The Category 1 metallurgical bond in JANS1N5807URS/TR refers to a diffusion-bonded interface between the silicon die and tungsten slug that meets MIL-STD-750 Test Method 2035 requirements. This bond ensures mechanical integrity, low thermal resistance, and resistance to interfacial delamination under thermal shock and sustained high-current operation-critical for preventing latent failures in long-duration missions.
Can JANS1N5807URS/TR be used in place of JANS1N5807US/TR?
Yes, JANS1N5807URS/TR can replace JANS1N5807US/TR electrically and functionally, as both share identical electrical specifications, junction temperature range, and hermetic construction. However, the URS package (square+round end caps) differs mechanically from the US package (two square end caps), requiring minor footprint adjustment in PCB layout. Thermal performance is nearly identical due to matching RθJEC (6.5 °C/W) and end-cap materials.
