Overview
JANTX1N5804URS/TR from Microsemi is a military-qualified ultrafast recovery glass rectifier diode in URS (one square + one round end cap) hermetic MELF-style package, rated at 100 V working peak reverse voltage, 2.5 A average forward current at TEC = 75 °C, and 25 ns reverse recovery time - deployed in high-reliability DC/DC converters and radiation-hardened power supplies.
For engineers reviewing the JANTX1N5804URS/TR datasheet, JANTX1N5804URS/TR pinout, JANTX1N5804URS/TR application, or JANTX1N5804URS/TR equivalent, key selection criteria include its MIL-PRF-19500/477 JANTX qualification, voidless glass hermetic seal, Category 1 metallurgical bond, and 13 °C/W junction-to-end-cap thermal resistance for thermal-limited high-surge designs.
Technical Context
This device implements an ultrafast silicon PN junction rectifier with controlled avalanche capability and quadruple-layer passivation, enabling stable operation under repetitive surge stress up to 35 A (8.3 ms, 1 min intervals). Its 25 ns reverse recovery time and low 0.975 V forward voltage at 2.5 A support high-frequency switching topologies without excessive switching loss.
The URS package uses tungsten slugs and tin/lead terminations with cathode band marking, delivering 193 mg mass and 13 °C/W RθJEC. It operates across –65 °C to +175 °C junction temperature range and exhibits 25 pF capacitance at 10 V / 1 MHz - critical for EMI-sensitive aerospace power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 100 V - maximum continuous reverse voltage before breakdown; defines safe operating margin in 48 V–72 V input DC/DC front-ends. |
| IO1 @ TEC = 75 °C | 2.5 A - sustained average forward current with end-cap heatsinking; enables compact 30–50 W converter designs. |
| trr | 25 ns - measured at IF = 0.5 A, IRM = 0.5 A, IR(REC) = 0.05 A; ensures minimal tail current loss in >200 kHz SMPS. |
| VF @ 2.5 A | 0.975 V - forward voltage drop at full rated current; directly determines conduction loss and thermal load. |
| RθJEC | 13 °C/W - junction-to-end-cap thermal resistance; allows direct mounting to metal chassis or heat spreaders without PCB copper pour. |
| C @ 10 V, 1 MHz | 25 pF - junction capacitance; impacts high-frequency noise coupling and snubber design in fast-switching circuits. |
| IFSM | 35 A - non-repetitive surge rating (8.3 ms); supports cold-start inrush and transient overload protection. |
Pinout & Package
Package: Hermetically sealed voidless glass URS (one square + one round end cap), 193 mg mass, tin/lead terminations, cathode indicated by color band. Dimensions per ASME Y14.5M: BD = 0.091–0.103", BL = 0.168–0.200", ECT = 0.019–0.028".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (square end cap) | Forward current entry point | Connects to unregulated input rail; requires mechanical anchoring due to glass body fragility. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-1N5804-M3/54 | Commercial-grade, non-hermetic DO-41 package; 100 V VRWM, 2.5 A IO, 50 ns trr - double the recovery time. | Lacks MIL-PRF-19500 qualification, radiation tolerance, and hermetic seal - unsuitable for space or avionics. | Select only for cost-sensitive industrial prototypes where qualification and long-term reliability are not mandated. |
| ON Semiconductor MUR220RLG | Surface-mount TO-220AC package; 200 V VRWM, 2 A IO, 35 ns trr; RoHS-compliant but not hermetically sealed. | Higher voltage rating but lower current and slower recovery; no military screening or Category 1 bond. | Use when board space constraints prohibit axial/MELF layout and 200 V margin is required over 100 V nominal input. |
Compared with JANTX1N5804URS/TR, both alternatives trade hermetic reliability and ultrafast timing for cost or packaging flexibility - neither meets JANTX-level screening, nor delivers the same combination of 25 ns trr, 100 V VRWM, and 13 °C/W thermal resistance in a qualified military package.

FAQ
What is the maximum junction temperature rating for JANTX1N5804URS/TR?
JANTX1N5804URS/TR has a specified junction and storage temperature range of –65 °C to +175 °C. This wide range supports operation in extreme environments such as engine bays, space payloads, and high-temperature industrial enclosures. The 175 °C upper limit is validated under MIL-PRF-19500/477 screening and enables thermal design headroom when paired with its 13 °C/W RθJEC value. JANTX1N5804URS/TR must be mounted to a thermally conductive surface to maintain this rating under full 2.5 A load.
Is JANTX1N5804URS/TR RoHS compliant?
No - JANTX1N5804URS/TR uses tin/lead (Sn/Pb) terminations per MIL-PRF-19500/477 requirements and is not RoHS compliant. RoHS-compliant versions are available only in commercial-grade variants (e.g., 1N5804URS with e3 suffix), which lack JANTX qualification, hermetic sealing, and Category 1 metallurgical bonds. JANTX1N5804URS/TR remains exempt under RoHS Annex III for military and space applications where reliability outweighs lead-free mandates.
How does the URS package differ from US in JANTX1N5804URS/TR?
The URS package features one square and one round end cap, while the US variant has two square end caps - both are hermetically sealed voidless glass configurations. This distinction affects mechanical mounting: URS allows asymmetric thermal interface design (e.g., square cap soldered to heatsink, round cap anchored mechanically), whereas US enables symmetrical pad layout. JANTX1N5804URS/TR's URS form factor is specified in MIL-PRF-19500/477 and validated for vibration resistance in launch environments.
What is the significance of "Category 1 metallurgical bond" in JANTX1N5804URS/TR?
Category 1 refers to a diffusion-bonded tungsten-silicon interface meeting MIL-STD-750 Method 2035 requirements - ensuring zero interfacial voids and atomic-level adhesion between die and slug. This bond survives >1,000 thermal cycles from –65 °C to +175 °C without delamination, directly enabling JANTX1N5804URS/TR's qualification for missile guidance systems and satellite power units. It is a foundational reliability feature absent in commercial rectifiers.
Can JANTX1N5804URS/TR replace JANTX1N5802URS/TR or JANTX1N5806URS/TR in a design?
JANTX1N5804URS/TR is not a direct substitute for JANTX1N5802URS/TR (50 V VRWM) or JANTX1N5806URS/TR (150 V VRWM) due to differing reverse voltage ratings - using it in place of JANTX1N5802URS/TR risks overvoltage failure, while substituting for JANTX1N5806URS/TR compromises surge margin. All three share identical package, trr, VF, and thermal specs, but VRWM is fixed per part number and cannot be interchanged without circuit revalidation. JANTX1N5804URS/TR is strictly a 100 V solution.
