Product details
Overview
JANTX1N5804US from Microsemi (now part of Microchip Technology) is a military-grade, hermetically sealed, silicon junction rectifier diode rated for 400V PIV and 3A average forward current. It operates with 1.1V typical forward voltage at 3A, exhibits 5μA maximum reverse leakage at 400V and 25°C, and is qualified to MIL-PRF-19500/215 for high-reliability aerospace and defense power conversion applications.
For engineers reviewing the JANTX1N5804US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, military qualification status, thermal derating guidance, package mechanical data, and validated alternatives for radiation-tolerant, high-temp DC-DC front-end and EMI filter rectification.
Technical Context
The JANTX1N5804US is a single-die, axial-lead, glass-passivated PN junction rectifier optimized for low forward drop and stable reverse blocking in harsh-environment power supplies. Its design targets continuous conduction mode (CCM) operation in 28V and 115VAC-derived DC rails where reliability under thermal cycling and vibration is critical.
It features a maximum junction temperature of +175°C, a thermal resistance of 20°C/W (junction-to-case), and is tested per MIL-STD-750 Method 2074 for surge current capability (100A non-repetitive peak). The device lacks integrated transient suppression - external TVS or MOV coordination is required for lightning or EOS protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PIV Rating | 400V - blocks up to 400V reverse voltage without breakdown; suitable for 28V systems with 120VAC line transients. |
| IF(AV) | 3A - continuous forward current rating at case temperature ≤75°C; requires heatsinking above 1.5A ambient. |
| VF @ 3A | 1.1V typical - low conduction loss enables >92% efficiency in 28V output rectifiers at full load. |
| IR @ 400V | 5μA max at 25°C - minimal leakage preserves hold-up capacitance in standby and low-power modes. |
| TJ Max | +175°C - supports operation in engine bay, avionics bays, and sealed enclosures without forced air. |
| MIL Qual | MIL-PRF-19500/215 - certified for screening including burn-in, temperature cycling, and hermeticity testing. |
Pinout & Package
Package: Axial-lead, DO-41 glass passivated body, 5.3mm diameter × 9.5mm length, hermetically sealed metal-glass construction. Leads are tinned copper, 0.6mm diameter, 25mm minimum length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to unregulated input or transformer secondary; must withstand surge currents up to 100A (non-repetitive). |
| Cathode (K) | Forward current exit point | Connected to bulk capacitor or downstream regulator; polarity marking is cathode band (black stripe) near lead end. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass-metal seal | Prevents moisture ingress and corrosion in 100% RH, salt fog, and vacuum environments per MIL-STD-883. |
| MIL-PRF-19500/215 screening | Includes lot acceptance tests (LAT), burn-in, and parametric verification - eliminates infant mortality in flight hardware. |
| 175°C junction rating | Enables use in conduction-cooled modules where PCB surface temp reaches +125°C without thermal shutdown. |
| Low VF temperature coefficient | Forward voltage increases only ~0.5mV/°C - ensures stable conduction loss across -65°C to +175°C operating range. |
Applications
| Aerospace Power Supplies | Defense Radar Transmitters |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N5804US | Non-hermetic, same die but plastic package; 150°C TJ max, no MIL screening. | Acceptable for ground-based industrial systems with controlled environment; not qualified for flight hardware. | Select when cost sensitivity outweighs radiation tolerance and hermeticity requirements. |
| 1N5804US (commercial) | No MIL screening, 125°C TJ max, higher IR (10μA), plastic DO-41 package. | Limited to benign commercial environments; unsuitable for vibration, humidity, or extended life cycles. | Use only for prototyping or non-critical subsystems where qualification overhead is prohibitive. |

FAQ
What is the maximum surge current rating for JANTX1N5804US?
JANTX1N5804US is rated for 100A non-repetitive peak surge current (IFSM) per MIL-STD-750 Method 2074. This rating applies to single half-sine pulses of 8.3ms duration at 25°C case temperature. Derating is required above 75°C case temperature per the published thermal curve; at 125°C case, the surge rating drops to approximately 65A.
Is JANTX1N5804US suitable for use in synchronous rectifier topologies?
No - JANTX1N5804US is a standard PN junction rectifier, not a Schottky or MOSFET-based synchronous rectifier. Its 1.1V forward drop and ~50ns reverse recovery time make it unsuitable for high-frequency (>100kHz) synchronous designs. It is intended for line-frequency and low-switching-frequency applications such as 28V/115VAC-derived DC supplies.
Does JANTX1N5804US have radiation hardness certification?
JANTX1N5804US is not radiation-hardened (rad-hard) and carries no TID or SEE certification. It is qualified to MIL-PRF-19500/215 for environmental robustness (vibration, thermal shock, hermeticity), but not for total ionizing dose (TID) or single-event effects (SEE) in space radiation environments. For rad-hard applications, Microchip's HTR-1N5804 or similar qualified parts must be used.
What is the thermal resistance (RθJC) of JANTX1N5804US?
The junction-to-case thermal resistance (RθJC) of JANTX1N5804US is 20°C/W, measured under standard test conditions per MIL-STD-750. This value assumes direct metal-to-metal contact between the diode's case and a heatsink with thermal interface material. PCB pad area and copper thickness significantly affect actual board-level RθJA, which is not specified for this hermetic axial package.
Can JANTX1N5804US replace 1N5804 in existing designs?
JANTX1N5804US shares identical electrical parameters (PIV, IF(AV), VF, IR) with commercial 1N5804 but adds hermetic sealing, MIL screening, and extended temperature range. Mechanical fit is identical (DO-41), but lead finish and marking differ. Replacement is electrically valid and improves reliability - however, requalification per MIL-STD-454 or system-level testing may be required for flight-critical use.
