Product details
Overview
JANTX1N5415US/TR from Microsemi is a military-qualified, voidless-hermetically sealed surface-mount fast recovery glass rectifier diode rated for 3 A average forward current, 50 V working peak reverse voltage (VRWM), and 150 ns reverse recovery time (trr), used in high-reliability DC power conversion stages of avionics power supplies and radiation-hardened satellite subsystems.
For engineers reviewing the JANTX1N5415US/TR datasheet, JANTX1N5415US/TR pinout, JANTX1N5415US/TR application, or JANTX1N5415US/TR equivalent, key selection criteria include its MIL-PRF-19500/411 JANTX qualification, Category 1 metallurgical bond, 80 A surge rating, -65°C to +175°C operating range, and D-5B (SQ-MELF) package compatibility with high-temperature reflow profiles.
Technical Context
This device operates as a unidirectional power rectifier in bridge and half-bridge topologies, leveraging a hard-glass hermetic seal with tungsten slugs and copper end caps to achieve low thermal resistance (RθJEC = 6.5°C/W) and stable junction temperature control under sustained 3 A conduction at +55°C ambient.
Its fast recovery behavior (trr = 150 ns) enables efficient switching in 50–400 kHz SMPS designs, while controlled avalanche capability (peak reverse power rated) and quadruple-layer passivation support operation in transient-prone military power rails without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 50 V - Maximum continuous reverse voltage before breakdown; defines safe blocking margin in 24–48 V input rectification stages. |
| IO @ TA=55°C | 3 A - Sustained average forward current with PCB thermal management; derates linearly to 2 A at +100°C ambient. |
| trr | 150 ns - Time to transition from forward conduction to reverse blocking; enables use in medium-frequency SMPS without excessive switching loss. |
| VF @ 9 A | 1.5 V - Forward voltage drop at high pulse current; determines conduction loss during surge events like inrush or fault recovery. |
| RθJEC | 6.5°C/W - Junction-to-end-cap thermal resistance; allows direct heatsinking via end caps in compact, conduction-cooled modules. |
| VBR @ 50 µA | 55 V - Minimum breakdown voltage; provides ≥10% overvoltage margin above VRWM for reliability under transients. |
| IFSM @ 8.3 ms | 80 A - Non-repetitive surge current rating; supports robustness against line surges and capacitor charging spikes. |
Pinout & Package
Package: D-5B (SQ-MELF) - Voidless hermetically sealed hard-glass cylindrical package with copper end caps (Sn/Pb finish), cathode band marking, and 539 mg mass. 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 solderable copper terminal; serves as primary thermal path to PCB or heatsink. |
| Cathode End Cap | Forward current exit / reverse voltage blocking node | Marked with black band; electrically isolated by glass body; supports high VRWM with minimal leakage (IR ≤ 1.0 µA @ 50 V, 25°C). |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates internal delamination risk under thermal cycling; certified for 2000+ cycles between -65°C and +175°C. |
| Category 1 metallurgical bond | Ensures mechanical integrity and low interfacial resistance at die-to-slug interface; required for JANTX-level reliability screening. |
| Quadruple-layer passivation | Prevents surface ion migration and moisture ingress; maintains IR stability in high-humidity, high-bias environments. |
| Controlled avalanche capability | Withstands repetitive peak reverse power events up to rated PRM without parametric shift or catastrophic failure. |
| Inherent radiation hardness | Qualified per MicroNote 050; exhibits no significant parameter shift after 100 krad(Si) total ionizing dose exposure. |
Applications
| Avionics Power Conversion | Satellite DC-DC Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5415US (commercial grade) | No MIL-PRF-19500/411 qualification; same electrical specs and D-5B package. | Lacks JANTX screening, burn-in, and lot traceability; unsuitable for DoD or space programs. | Select only for non-military prototypes or cost-sensitive commercial test fixtures where full qualification is not mandated. |
| Vishay VS-3EJH02-M3/54 | Same 50 V VRWM and 3 A IO, but TO-277 package (not hermetic); trr = 125 ns; RoHS-compliant matte tin only. | Higher thermal resistance (RθJA ≈ 50°C/W vs. JANTX1N5415US/TR's 6.5°C/W to end cap); no radiation hardness data. | Use where board space permits TO-277 footprint and radiation tolerance is not required; avoid in sealed, high-reliability enclosures. |
Compared with 1N5415US (commercial) and VS-3EJH02-M3/54, JANTX1N5415US/TR uniquely delivers MIL-qualified reliability, hermetic sealing, and end-cap thermal conduction-critical for systems where field failure is unacceptable and thermal management is constrained.

FAQ
What is the maximum operating temperature for JANTX1N5415US/TR?
JANTX1N5415US/TR has a specified junction and storage temperature range of -65°C to +175°C. Its thermal resistance junction-to-end-cap is 6.5°C/W, enabling reliable operation at full 3 A current up to +55°C ambient when properly heatsunk via the end caps. Derating applies linearly above +55°C ambient.
Is JANTX1N5415US/TR RoHS compliant?
No, JANTX1N5415US/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e3 suffix) are available only for commercial-grade variants (e.g., 1N5415US e3). The JANTX level retains Sn/Pb finish on copper end caps to meet MIL-PRF-19500/411 solderability and reliability requirements.
What does the "TR" suffix indicate in JANTX1N5415US/TR?
The "TR" suffix denotes tape-and-reel packaging per EIA-481-B standard. JANTX1N5415US/TR is supplied in industry-standard carrier tape compatible with automated SMT placement equipment, with quantities and reel sizes coordinated through Microsemi's factory prior to order fulfillment.
How does JANTX1N5415US/TR differ from standard 1N5415 diodes?
JANTX1N5415US/TR undergoes full MIL-PRF-19500/411 screening-including extended burn-in, lot acceptance testing, and traceable lot documentation-unlike commercial 1N5415 parts. It also features voidless hermetic glass construction and Category 1 metallurgical bonds, ensuring performance stability under shock, vibration, and thermal cycling stress.
Can JANTX1N5415US/TR be used in place of axial-leaded 1N5415 in existing designs?
No direct substitution is recommended. JANTX1N5415US/TR uses the D-5B (SQ-MELF) surface-mount package, while axial-leaded 1N5415 uses DO-41. Pad layout, thermal path, and mounting method differ fundamentally. A redesign of the PCB footprint and thermal interface is required to migrate from through-hole to JANTX1N5415US/TR.
