Product details
Overview
JANTX1N5806URS/TR from Microsemi is a military-qualified ultrafast recovery glass rectifier diode rated for 2.5 A average forward current at TEC = +75 °C, 150 V working peak reverse voltage (VRWM), and 25 ns reverse recovery time (trr); used in high-reliability switching power supplies, avionics DC-DC converters, and radiation-hardened power conversion stages.
For engineers reviewing the JANTX1N5806URS/TR datasheet, JANTX1N5806URS/TR pinout, JANTX1N5806URS/TR application, or JANTX1N5806URS/TR equivalent, key selection criteria include hermetic voidless glass packaging, Category 1 metallurgical bond integrity, MIL-PRF-19500/477 JANTX qualification level, and thermal resistance of 13 °C/W junction-to-end cap.
Technical Context
This device implements an ultrafast recovery rectification function using a planar diffused silicon junction with quadruple-layer passivation and tungsten slug end caps. Its 25 ns trr enables operation in high-frequency SMPS topologies up to 500 kHz while maintaining low forward voltage drop (0.975 V @ 2.5 A) and controlled avalanche capability.
The URS package-featuring one square and one round end cap-is hermetically sealed with voidless glass construction and rated for -65 °C to +175 °C junction temperature. It delivers 35 A non-repetitive forward surge current (IFSM) and exhibits 25 pF capacitance at 10 V reverse bias and 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 150 V - Maximum continuous reverse voltage before breakdown; defines safe operating range in DC-link and output rectification stages. |
| IO1 | 2.5 A @ TEC = +75 °C - Average rectified current rating under controlled end-cap thermal conditions; requires heatsinking above 125 °C. |
| trr | 25 ns - Reverse recovery time measured at IF = 0.5 A, IRM = 0.5 A; enables high-frequency switching with minimal commutation loss. |
| VF | 0.975 V @ IF = 2.5 A - Forward voltage drop directly impacts conduction loss and thermal design in high-current paths. |
| RθJEC | 13 °C/W - Junction-to-end-cap thermal resistance; determines required external thermal path for reliable 2.5 A operation. |
| C | 25 pF @ VR = 10 V, f = 1 MHz - Junction capacitance affects EMI generation and snubber design in fast-switching circuits. |
| IFSM | 35 A - Non-repetitive surge current rating; supports inrush and fault transient handling without degradation. |
Pinout & Package
The JANTX1N5806URS/TR uses the URS package: hermetically sealed voidless glass with one square and one round end cap, cathode indicated by color band, tin/lead terminations, and 193 mg mass. Dimensions per MIL-PRF-19500/477: Ltr = 0.091–0.103 in, BL = 0.168–0.200 in, ECT = 0.019–0.028 in.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side of rectifier; must withstand full surge current and thermal stress during conduction. |
| Cathode | Forward current exit point | Marked by color band; connects to load/output; carries full average current and defines reverse blocking polarity. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic voidless glass seal | Prevents moisture ingress and internal corrosion; ensures long-term reliability in vacuum, space, and high-humidity environments. |
| Category 1 metallurgical bond | Internal tungsten-silicon bond qualified to MIL-STD-750 Method 2035; guarantees mechanical robustness under shock/vibration. |
| Controlled avalanche capability | Rated peak reverse power handling enables safe clamping during inductive turn-off transients without failure. |
| Quadruple-layer passivation | Enhanced surface protection against ion migration and surface leakage; critical for stable performance at 175 °C junction. |
| MIL-PRF-19500/477 JANTX qualification | Full screening including burn-in, temperature cycling, and life test per military standard; traceable lot documentation provided. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N5806US/TR | Same electrical specs but US package (two square end caps); RθJEC = 13 °C/W identical; same MIL-PRF-19500/477 JANTX screening. | US variant optimized for symmetric PCB pad layout; URS preferred where asymmetric mounting or mechanical strain relief required. | Select JANTX1N5806US/TR only if board layout uses dual square pads; otherwise URS provides superior mechanical stability. |
| CDP150150G | Commercial-grade 150 V / 2.5 A ultrafast rectifier; RoHS-compliant; no MIL qualification; trr = 35 ns; RθJA = 65 °C/W (not junction-to-end-cap). | Not suitable for aerospace or radiation environments; limited to industrial/commercial SMPS with relaxed reliability requirements. | Use CDP150150G only for cost-sensitive, non-military designs where MIL screening and hermeticity are unnecessary. |
Compared with JANTX1N5806US/TR and CDP150150G, the JANTX1N5806URS/TR uniquely combines asymmetric URS mechanical form factor, hermetic voidless glass, and full JANTX-level military screening-enabling deployment in mission-critical systems where field failure is unacceptable.

FAQ
What does "URS" signify in JANTX1N5806URS/TR?
The "URS" suffix identifies the specific package configuration: one square and one round end cap, per MIL-PRF-19500/477. This asymmetric geometry improves mechanical strain relief in vibration-prone environments. The JANTX1N5806URS/TR uses voidless hermetic glass sealing and tungsten slugs, distinguishing it from the US (dual square) variant. Both share identical electrical ratings and JANTX qualification.
Is JANTX1N5806URS/TR RoHS compliant?
No-JANTX1N5806URS/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e3 marking) are available only for commercial-grade variants, not for JANTX-level military-qualified parts. The JANTX1N5806URS/TR uses traditional tin/lead terminations to ensure solder joint reliability under thermal cycling and mechanical stress per MIL-STD-883.
What is the maximum junction temperature for JANTX1N5806URS/TR?
The JANTX1N5806URS/TR has a specified junction and storage temperature range of -65 °C to +175 °C. Operation at +175 °C requires strict thermal management-derating begins at +125 °C (50 mA/°C), and the 13 °C/W RθJEC mandates direct end-cap heatsinking. Exceeding +175 °C risks irreversible metallurgical bond degradation.
How does JANTX1N5806URS/TR differ from commercial 1N5806 equivalents?
JANTX1N5806URS/TR differs in qualification level, construction, and screening: it is fully MIL-PRF-19500/477 JANTX-qualified with hermetic voidless glass, Category 1 metallurgical bonds, and 100% lot testing-including burn-in and temperature cycling. Commercial 1N5806 parts lack military screening, use plastic or non-hermetic packages, and have looser parametric tolerances and no radiation hardness assurance.
Can JANTX1N5806URS/TR replace JANTX1N5806US/TR in existing designs?
JANTX1N5806URS/TR can replace JANTX1N5806US/TR electrically and thermally (same RθJEC, VRWM, trr), but mechanical compatibility must be verified: URS has one round end cap, requiring asymmetric PCB pad layout. No electrical redesign is needed, but mechanical mounting and strain relief may improve in high-vibration applications due to the URS geometry.
