Product details
Overview
JANTX1N5802URS/TR from Microsemi is a military-qualified ultrafast recovery glass rectifier diode in URS package (one square + one round end cap), rated at 50 V working peak reverse voltage, 2.5 A average rectified current at TEC = 75 °C, and 25 ns reverse recovery time; used in high-reliability switching power supplies requiring low forward voltage drop and controlled avalanche capability.
For engineers reviewing the JANTX1N5802URS/TR datasheet, JANTX1N5802URS/TR pinout, JANTX1N5802URS/TR application, or JANTX1N5802URS/TR equivalent, key selection criteria include hermetic voidless glass construction, Category 1 metallurgical bond, MIL-PRF-19500/477 JANTX qualification, thermal resistance of 13 °C/W (junction-to-end cap), and RoHS-compliant tin/lead termination options.
Technical Context
This device operates as a unidirectional power rectifier with ultrafast recovery optimized for high-frequency DC–DC conversion and EMI-sensitive environments. Its 25 ns trr and 0.875 V forward voltage at 1.0 A enable efficient operation in 100–500 kHz switching topologies while maintaining low conduction loss and minimal reverse recovery charge.
The URS package features tungsten slugs and hermetically sealed voidless glass construction, delivering robust thermal performance (RθJEC = 13 °C/W) and radiation hardness per MicroNote 050. Polarity is marked by cathode band; terminals are tin/lead over nickel over copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 50 V - Maximum continuous reverse voltage before breakdown under full operating temperature range (-65 to +175 °C) |
| IO1 | 2.5 A @ TEC = 75 °C - Sustained average forward current with end-cap heatsinking; derates linearly above 125 °C |
| trr | 25 ns - Time from zero-crossing to 5% of peak reverse current; enables clean turn-off in high-frequency SMPS |
| VF | 0.875 V @ IF = 1.0 A - Low conduction loss reduces power dissipation and improves efficiency in high-current paths |
| RθJEC | 13 °C/W - Junction-to-end-cap thermal resistance supports direct mounting to metal chassis or heat spreaders |
| IFSM | 35 A - Peak non-repetitive surge current handling for line transients and startup inrush |
| C | 25 pF @ VR = 10 V, 1 MHz - Low junction capacitance minimizes switching noise and EMI generation |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input source or transformer secondary; requires low-inductance layout to minimize voltage overshoot during turn-off |
| Cathode | Forward current exit point | Marked by color band; connects to output filter capacitor or load; serves as reference node for snubber placement |

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-1N5802-M3/54 | Commercial-grade, plastic-molded TO-277 package; trr = 35 ns; VF = 0.95 V @ 1 A; not hermetically sealed | Lacks MIL qualification, radiation hardness, and voidless glass reliability; suitable only for industrial non-critical use | Select when cost and volume production outweigh mission-critical reliability requirements |
| ON Semiconductor MUR260G | Surface-mount TO-277A; 600 V VRWM; trr = 35 ns; VF = 1.15 V @ 2 A; commercial grade only | Higher voltage rating but slower recovery and higher VF; no military screening or hermetic packaging | Choose only for non-military 600 V applications where 25 ns trr is not required |
Compared with JANTX1N5802URS/TR, VS-1N5802-M3/54 and MUR260G lack hermetic voidless glass, MIL-PRF-19500 qualification, and radiation hardness-making them unsuitable for aerospace, defense, or space applications where single-point failure is unacceptable.

FAQ
What is the maximum working peak reverse voltage for JANTX1N5802URS/TR?
The JANTX1N5802URS/TR has a VRWM of 50 V, meaning it can sustain up to 50 V of reverse voltage across its terminals over the full operating temperature range of −65 °C to +175 °C without breakdown. This rating is verified per MIL-PRF-19500/477 screening and applies to both steady-state and transient conditions within specified limits.
Is JANTX1N5802URS/TR RoHS compliant?
JANTX1N5802URS/TR is not RoHS compliant, as it uses traditional tin/lead (Sn/Pb) termination per MIL-PRF-19500/477 requirements. RoHS-compliant versions are available only in commercial-grade variants (e.g., 1N5802US with e3 suffix), not in JANTX-level hermetic devices.
What does "URS" mean in JANTX1N5802URS/TR?
"URS" denotes the package configuration: one square end cap and one round end cap, distinguishing it from the US variant (two square end caps). This geometry enables asymmetric thermal mounting and is specified in Microsemi's nomenclature guide for hermetic glass rectifiers per T4-LDS-0211-1.
How is polarity identified on JANTX1N5802URS/TR?
Polarity is indicated by a visible cathode band painted on the glass body of the JANTX1N5802URS/TR. The banded end is the cathode; the opposite end is the anode. This marking complies with MIL-PRF-19500/477 visual inspection requirements and is verified during final test screening.
What is the thermal resistance from junction to end cap for JANTX1N5802URS/TR?
The JANTX1N5802URS/TR has a junction-to-end-cap thermal resistance (RθJEC) of 13 °C/W, measured per Figure 1 in T4-LDS-0211-1. This value enables direct thermal coupling to a metal chassis or heatsink via the end caps, supporting 2.5 A continuous operation at TEC = 75 °C without additional forced cooling.
