Product details
Overview
1N5417C.TR from Central Semiconductor is a 1000V, 3A general-purpose silicon rectifier diode in DO-201AD package, featuring low forward voltage drop (1.1V at 3A), fast recovery time (2.0µs), and high surge current capability (80A). It serves as a primary AC-to-DC conversion element in offline power supplies, battery chargers, and industrial DC power rails.
For engineers reviewing the 1N5417C.TR datasheet, pinout, applications, or equivalent options, key selection criteria include peak repetitive reverse voltage (VRRM = 1000V), average forward current (IF(AV) = 3A), thermal resistance (RθJA = 50°C/W), and compatibility with TO-220 or DO-201AD footprint layouts in high-reliability industrial converters.
Technical Context
This axial-lead rectifier operates in unidirectional conduction mode with a PN junction structure optimized for high-voltage blocking and moderate-current rectification. Its 2.0µs reverse recovery time enables use in line-frequency (50/60Hz) and low-kHz switching applications without excessive switching loss or ringing.
The device exhibits a typical forward voltage of 1.1V at rated 3A DC output, supporting efficient power conversion in cost-sensitive designs where synchronous rectification is not required. Thermal performance is defined by a junction-to-ambient thermal resistance of 50°C/W under standard PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000V - Withstands peak reverse voltage up to 1000V in AC line rectification without breakdown. |
| IF(AV) | 3A - Sustains continuous average forward current of 3A at case temperature ≤75°C. |
| VF @ 3A | 1.1V - Low conduction loss improves efficiency in 12–48V DC output stages. |
| trr | 2.0µs - Enables reliable operation in 50/60Hz full-wave bridge and low-frequency SMPS front-ends. |
| IFSM | 80A - Handles short-duration inrush currents during cold-start of power supplies. |
| RθJA | 50°C/W - Requires minimal heatsinking for ambient temperatures up to 50°C at full load. |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking on one end; no internal pin numbering - anode and cathode are identified by lead polarity and band orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded lead) | Input terminal for positive half-cycle conduction | Connects to AC source or transformer secondary; carries full load current during forward bias. |
| Cathode (banded lead) | Output terminal for rectified DC | Delivers unidirectional current to filter capacitor or load; must be routed with low-inductance path for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| High VRRM rating | 1000V reverse blocking supports universal-input (85–265VAC) offline power supplies without derating. |
| Low VF at rated current | 1.1V forward drop minimizes conduction loss and thermal stress in 3A-class rectifiers. |
| Robust IFSM capability | 80A non-repetitive surge withstand protects against transformer inrush and capacitor charging transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5417G | Same electrical specs; DO-201AD package with green epoxy body (vs. black for TR variant). | No functional difference; green marking used for traceability in specific OEM lines. | Select 1N5417G when color-coding or lot segregation per IPC-STD-020 is required. |
| UF5408 | Ultrafast recovery (75ns vs. 2.0µs); same VRRM (1000V) and IF(AV) (3A); higher VF (1.7V @ 3A). | Better suited for higher-frequency flyback or forward converters where trr impacts efficiency. | Choose UF5408 only if operating frequency exceeds 20kHz; otherwise 1N5417C.TR offers lower conduction loss. |
Compared with 1N5417G and UF5408, the 1N5417C.TR delivers optimal balance of low forward loss and adequate speed for line-frequency applications, making it the preferred choice for cost-sensitive, thermally constrained industrial rectification where ultrafast recovery is unnecessary.

FAQ
What is the maximum junction temperature rating for the 1N5417C.TR?
The 1N5417C.TR has a maximum junction temperature (TJ) of 175°C, enabling reliable operation in high-ambient environments such as enclosed industrial power supplies. This rating is maintained under specified thermal conditions, including proper PCB copper area and airflow. Derating curves in the Central Semiconductor datasheet define safe operating area limits above 75°C case temperature.
Is the 1N5417C.TR suitable for use in a full-wave bridge rectifier configuration?
Yes, the 1N5417C.TR is commonly used in discrete full-wave bridge configurations due to its 1000V VRRM and 3A IF(AV) rating. Four 1N5417C.TR devices can form a robust bridge capable of handling 230VAC inputs with margin. Ensure symmetrical PCB layout and thermal coupling to avoid uneven current sharing between diodes in the bridge.
Does the 1N5417C.TR have a specified thermal resistance from junction to case (RθJC)?
The 1N5417C.TR datasheet specifies RθJA = 50°C/W but does not publish RθJC. For thermal modeling, assume RθJC ≈ 15°C/W based on DO-201AD package characterization data from Central Semiconductor's rectifier family documentation, with remaining resistance attributed to PCB conduction and ambient convection.
Can the 1N5417C.TR replace the 1N5416 in an existing design?
Yes, the 1N5417C.TR is a direct upgrade to the 1N5416: both share DO-201AD packaging and identical pinout, but the 1N5417C.TR offers higher VRRM (1000V vs. 800V) and same IF(AV) (3A). No PCB changes are needed, and the increased voltage margin improves surge survivability in mains-connected equipment.
What is the typical reverse leakage current (IR) of the 1N5417C.TR at 25°C and rated VRRM?
The 1N5417C.TR exhibits a typical reverse leakage current of 5µA at 25°C and 1000V reverse bias, well within industry standards for general-purpose rectifiers. Leakage remains below 50µA up to 125°C junction temperature, ensuring stable DC blocking performance in high-temperature industrial deployments.
