Product details
Overview
JANTXV1N5419US/TR from Microsemi is a military-qualified, voidless-hermetically sealed surface-mount fast recovery glass rectifier diode rated for 3 A average forward current, 500 V working peak reverse voltage (VRWM), and 250 ns maximum reverse recovery time (trr), used in high-reliability power conversion circuits such as DC-DC converter output stages and EMI-filtered AC-DC front ends.
For engineers reviewing the JANTXV1N5419US/TR datasheet, JANTXV1N5419US/TR pinout, JANTXV1N5419US/TR application, or JANTXV1N5419US/TR equivalent, key selection criteria include its MIL-PRF-19500/411 JANTXV qualification, Category 1 metallurgical bond, 6.5 °C/W junction-to-end-cap thermal resistance, and robust 80 A surge capability under 8.3 ms half-sine waveform.
Technical Context
This device belongs to Microsemi's SQ-MELF "B" package (D-5B) fast recovery rectifier family, designed for high-reliability environments where hermetic sealing and radiation tolerance are mandatory. It features quadruple-layer passivation and controlled avalanche behavior with peak reverse power capability, enabling operation in harsh thermal and radiation-exposed conditions without degradation.
The JANTXV1N5419US/TR delivers 1.5 V maximum forward voltage at 9 A, 1.0 µA max reverse leakage at VRWM and 25 °C, and 20 µA at 100 °C - all specified per MIL-PRF-19500/411 test protocols. Its 539 mg mass and tungsten-slug construction ensure mechanical stability and low thermal impedance in conduction-limited applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 500 V - Maximum continuous reverse voltage before breakdown; defines safe operating margin in 400–500 V DC bus applications. |
| trr | 250 ns - Reverse recovery time measured at IF = 0.5 A, IRM = 1 A; enables use in 50–100 kHz switching topologies with minimal commutation loss. |
| IO @ TA = 55 °C | 3 A - Average rectified forward current at 55 °C ambient; derates linearly to 2 A at 100 °C, supporting thermally constrained PCB layouts. |
| RθJEC | 6.5 °C/W - Junction-to-end-cap thermal resistance; allows direct heat sinking via end caps, critical for high-duty-cycle power supplies. |
| IFSM | 80 A - Non-repetitive forward surge current at 8.3 ms half-sine; withstands inrush and fault currents in industrial motor drives and UPS systems. |
| VF @ 9 A | 1.5 V - Forward voltage drop at high transient load; determines conduction loss and thermal rise during short-duration overloads. |
| TJ/TSTG | –65 to +175 °C - Operating and storage temperature range; supports deployment in aerospace avionics and downhole oilfield electronics. |
Pinout & Package
Package: SQ-MELF "B" (D-5B), hermetically sealed voidless glass with tungsten slugs and copper end caps plated with Sn/Pb. Cathode indicated by single band. Weight: 539 mg. Dimensions: BL = 0.200–0.225 in (5.08–5.72 mm), BD = 0.137–0.148 in (3.48–3.76 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (End Cap) | Forward current entry point | Directly bonded to tungsten slug; serves as primary thermal path and high-current interface in PCB-mounted configurations. |
| Cathode (Banded End Cap) | Forward current exit / reverse blocking terminal | Marked with cathode band; engineered for controlled avalanche and stable reverse leakage up to 100 °C ambient. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates moisture ingress and internal delamination, ensuring >20-year reliability in vacuum or high-humidity military enclosures. |
| Category 1 metallurgical bond | Guarantees interfacial integrity between silicon die and tungsten slug under thermal cycling (–65 to +175 °C), preventing bond lift or crack propagation. |
| Controlled avalanche capability | Enables safe clamping of inductive kickback in relay drivers and solenoid controls without catastrophic failure or parameter drift. |
| Quadruple-layer passivation | Provides immunity to surface ion migration and contamination-induced leakage, validated per MIL-PRF-19500/411 screening. |
| Low RθJEC (6.5 °C/W) | Permits direct end-cap thermal coupling to heatsinks or copper pour, reducing junction temperature rise by ≥15 °C vs. standard SOD-123 packages. |
Applications
| Avionics Power Distribution | Downhole Telemetry Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EY50A-M3/54 | Commercial-grade, 500 V VRWM, 3 A IO, but only 150 ns trr and no MIL qualification; RoHS-compliant matte-tin finish. | Lacks JANTXV-level screening, radiation hardness, and hermetic seal; unsuitable for aerospace or nuclear environments. | Select when cost, lead time, or RoHS compliance outweigh military reliability requirements. |
| ON Semiconductor MUR360RLG | Ultrafast recovery (60 ns trr), 600 V VRWM, 3 A IO, plastic DO-214AB package; no hermetic seal or MIL qualification. | Higher speed enables >200 kHz operation but sacrifices long-term reliability in humid, high-vibration, or radiation-prone settings. | Prefer for commercial high-frequency SMPS where thermal cycling and radiation exposure are not concerns. |
Compared with VS-3EY50A-M3/54 and MUR360RLG, the JANTXV1N5419US/TR trades higher trr for guaranteed hermeticity, Category 1 bonding, and full MIL-PRF-19500/411 JANTXV qualification - making it the sole choice for mission-critical systems where field failure is unacceptable.

FAQ
What is the maximum junction temperature rating for JANTXV1N5419US/TR?
The JANTXV1N5419US/TR has a maximum junction temperature (TJ) of +175 °C and a storage temperature (TSTG) range of –65 to +175 °C, verified per MIL-PRF-19500/411 testing. This rating enables operation in engine-bay electronics and downhole tools where ambient temperatures exceed 150 °C. The device maintains electrical stability across this full range due to its Category 1 metallurgical bond and voidless glass seal.
Does JANTXV1N5419US/TR have a RoHS-compliant version?
No - the JANTXV1N5419US/TR uses Sn/Pb-plated copper end caps and is non-RoHS compliant, consistent with MIL-PRF-19500/411 JANTXV requirements. RoHS-compliant matte-tin versions are available only for commercial-grade 1N5419US devices (no JAN/JANTX/JANTXV/JANS suffix), not for JANTXV1N5419US/TR. This distinction is documented in Microsemi's T4-LDS-0231-1 datasheet revision notes.
What is the reverse recovery time (trr) specification for JANTXV1N5419US/TR?
The JANTXV1N5419US/TR has a maximum reverse recovery time (trr) of 250 ns, measured under IF = 0.5 A, IRM = 1 A, and IR(REC) = 0.250 A per MIL-PRF-19500/411 test conditions. This value is specific to the 1N5419US variant and differs from faster variants like 1N5415US (150 ns) and slower ones like 1N5420US (400 ns), confirming its optimized balance of speed and ruggedness for 400–500 V applications.
How is polarity marked on JANTXV1N5419US/TR?
JANTXV1N5419US/TR uses a single cathode band on the glass body to indicate polarity, consistent with JEDEC-standard marking for MELF devices. The banded end cap is the cathode; the opposite end cap is the anode. No alphanumeric marking is applied - only the band - as confirmed in the "MECHANICAL and PACKAGING" section of Microsemi's T4-LDS-0231-1 datasheet.
What is the thermal resistance from junction to end cap (RθJEC) for JANTXV1N5419US/TR?
The JANTXV1N5419US/TR has a specified thermal resistance of 6.5 °C/W from junction to end cap (RθJEC), measured per MIL-PRF-19500/411. This low value results from direct tungsten-slug bonding and copper end-cap construction, enabling efficient heat transfer to PCB copper pours or external heatsinks - a key advantage over plastic-packaged rectifiers with RθJA > 40 °C/W.
