Product details
Overview
1N5397G-T from Diodes Incorporated is a 1.5A, 600V glass passivated general-purpose rectifier diode in DO-15 package, featuring 1.1V forward voltage at 1.5A, 50A non-repetitive surge capability, and 5.0µA reverse leakage at 25°C, used in AC/DC power supplies, adapter circuits, and input stage rectification.
For engineers reviewing the 1N5397G-T datasheet, 1N5397G-T pinout, 1N5397G-T application, or 1N5397G-T equivalent, key selection criteria include peak repetitive reverse voltage (600V), average rectified current (1.5A @ 55°C), thermal resistance (80°C/W), and DO-15 mechanical compatibility in low-to-medium power offline converters.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for 60Hz line-frequency applications with resistive or inductive loads. It employs glass passivation for enhanced surface stability and moisture resistance, and its junction-to-ambient thermal resistance of 80°C/W requires adequate PCB copper area for thermal management at full rated current.
The diode exhibits typical total capacitance of 15pF at 1MHz and 4V reverse bias, limiting high-frequency switching use; derating to 80% current is required for capacitive loads per manufacturer specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum peak reverse voltage the diode blocks without breakdown; defines maximum AC input voltage rating in bridge or half-wave configurations. |
| IO @ TA=55°C | 1.5 A - Continuous average forward current sustainable with leads held at ambient at 9.5mm from case; requires thermal design margin below 55°C ambient. |
| VFM @ IF=1.5A | 1.1 V - Forward voltage drop determining conduction loss (1.65W at 1.5A); impacts efficiency and heatsink sizing in linear power stages. |
| IFSM | 50 A - Non-repetitive surge current tolerance for 8.3ms half-sine; supports inrush current handling during cold start of transformer-based supplies. |
| IRM @ 25°C | 5.0 µA - Reverse leakage at rated DC blocking voltage; low value minimizes standby power loss in high-impedance bias networks. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance; dictates minimum copper pour area needed on PCB to maintain Tj ≤ 175°C under load. |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0), cathode indicated by band, lead finish tin, weight ≈0.4 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must withstand peak inverse voltage and surge current stress. |
| Cathode | Forward current exit point | Connected to filter capacitor or load; polarity marking (band) critical for correct orientation in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enables stable long-term reverse leakage performance and improved humidity resistance vs. epoxy-passivated alternatives. |
| 50A surge rating | Supports reliable operation during repeated cold-start events in wall adapters and industrial power modules without fusing. |
| DO-15 standard footprint | Ensures direct replacement compatibility with legacy designs using 1N400x, 1N539x, and similar axial-leaded rectifiers. |
| RoHS-compliant tin finish | Guarantees solderability per MIL-STD-202 Method 208 and eliminates lead-based assembly concerns in modern manufacturing. |
Applications
| AC/DC Wall Adapters | Industrial Control Power Supplies |
|---|---|
Use Scenario: Rectifying 120/230VAC mains input in compact external power adapters for consumer electronics. IC Role / Device Role / Timing Role: General-purpose rectifier in single-phase half-wave or bridge configuration. Use Value: 600V VRRM provides 2× safety margin over 230VAC peak (325V), while 1.1V VFM limits conduction loss in space-constrained enclosures. | Use Scenario: Input-stage rectification in DIN-rail mounted 24VDC power supplies for PLC I/O modules. IC Role / Device Role / Timing Role: Primary-side diode in unregulated linear supply feeding regulator ICs. Use Value: 50A IFSM handles motor controller startup surges; DO-15 form factor allows manual replacement in field-serviceable units. |
| LED Driver Input Stages | Appliance Power Entry Modules |
Use Scenario: Bridge rectification in non-isolated LED drivers for commercial lighting fixtures. IC Role / Device Role / Timing Role: High-voltage leg rectifier in full-wave bridge configuration. Use Value: Low 5.0µA IRM reduces no-load power consumption; glass passivation ensures reliability under elevated ambient temperatures near LEDs. | Use Scenario: Mains rectification in white goods (refrigerators, washing machines) with integrated EMI filtering. IC Role / Device Role / Timing Role: Bulk rectifier preceding bulk capacitor and PFC stage. Use Value: 80°C/W RθJA enables thermal coupling to metal chassis; UL 94V-0 case meets appliance flammability requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4007-T | Same 1000V VRRM but lower 1.0A IO rating and higher 1.2V VFM at 1A. | Marginally suitable for 600V designs requiring >1.0A continuous current. | Select only if existing 1N4007 footprint reuse is mandatory and peak current remains <1.0A. |
| RS1M-T | Same 1.5A/1000V rating but faster recovery (500ns vs. ~2µs) and DO-41 package. | Better suited for higher-frequency flyback snubbers or quasi-resonant converters. | Choose when reduced reverse recovery loss or DO-41 mounting is required; not drop-in due to different body dimensions. |
Compared with 1N4007-T and RS1M-T, the 1N5397G-T offers optimal balance of surge robustness (50A), thermal resistance (80°C/W), and DO-15 compatibility for cost-sensitive 60Hz line rectification-making it preferable where legacy axial-leaded replacement and proven reliability are prioritized over speed or ultra-high voltage margin.

FAQ
Is the 1N5397G-T RoHS compliant?
Yes, the 1N5397G-T features a lead-free finish and is RoHS compliant per EU Directive Annex Notes 5 and 7, with exemptions applied for glass and high-temperature solder. Tin-plated leads meet MIL-STD-202 Method 208 solderability requirements.
What is the maximum operating temperature for the 1N5397G-T?
The 1N5397G-T has an operating junction temperature range of –65°C to +175°C. Its thermal resistance (RθJA = 80°C/W) means that at 1.5A average current, ambient temperature must be limited to ≤55°C to keep junction temperature within rating, assuming standard PCB mounting conditions.
Can the 1N5397G-T replace a 1N4007 in existing designs?
Yes, the 1N5397G-T is mechanically and electrically compatible with the 1N4007 in DO-15 packages, offering higher average current (1.5A vs. 1.0A) and identical 1000V peak reverse voltage. However, verify thermal design margins, as VFM is specified at 1.5A rather than 1.0A.
Why is the 1N5397G-T marked "NOT RECOMMENDED FOR NEW DESIGN"?
Diodes Incorporated designates the 1N539xG series as "NOT RECOMMENDED FOR NEW DESIGN" due to industry migration toward higher-efficiency, lower-VF alternatives (e.g., Schottky or fast-recovery diodes) and newer packaging formats. The part remains fully supported and available for legacy repair and continuity programs.
