Product details
Overview
1N5392G-T from Diodes Incorporated is a 1.5A glass passivated general-purpose rectifier diode with 100V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 1.5A, and 50A non-repetitive surge current capability; used in AC/DC power supplies, adapter circuits, and low-frequency rectification where cost-effective discrete diode performance is required.
For engineers reviewing the 1N5392G-T datasheet, 1N5392G-T pinout, 1N5392G-T application, or 1N5392G-T equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (80°C/W), reverse leakage (5µA @ 25°C), and DO-15 package compatibility with through-hole PCB layouts.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for 60Hz line-frequency applications. Its glass passivated junction ensures stable reverse characteristics and low IR across temperature, while the DO-15 molded plastic case provides mechanical robustness and UL 94V-0 flammability compliance.
The diode exhibits a typical junction-to-ambient thermal resistance of 80°C/W under standard mounting conditions (leads held at ambient 9.5mm from case), and its forward voltage remains ≤1.1V up to rated DC output current, enabling efficient power conversion in low-voltage secondary-side rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum peak reverse voltage the diode blocks without breakdown; defines safe operating limit in AC input stages. |
| IO @ TA=55°C | 1.5 A - Average forward current rating at 55°C ambient; requires heatsinking or airflow above this temperature. |
| VFM @ IF=1.5A | 1.1 V - Forward voltage drop at full rated current; determines conduction loss and thermal dissipation (1.65W max). |
| IFSM | 50 A - Non-repetitive surge current tolerance for 8.3ms half-sine; supports inrush current handling in transformer-fed supplies. |
| IRM @ 25°C | 5 µA - Reverse leakage at rated blocking voltage and room temperature; critical for low-power standby circuit integrity. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance; sets temperature rise per watt under natural convection mounting. |
| CT @ 1MHz | 15 pF - Junction capacitance at 4V reverse bias; negligible impact on 50/60Hz rectification but relevant for EMI filtering design. |
Pinout & Package
Package: DO-15 molded plastic case with cathode band marking; lead finish is matte tin, solderable per MIL-STD-202 Method 208; weight ≈0.4 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary winding; must withstand surge current and thermal stress. |
| Cathode | Forward current exit point | Connected to load or filter capacitor; marked by visible band; polarity-critical for correct rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and moisture resistance versus epoxy-passivated alternatives; reduces parameter drift over time. |
| 50A surge rating | Enables use in transformer-coupled supplies with high inrush without external fusing or derating. |
| Low IR (5µA @ 25°C) | Maintains high efficiency in low-power standby modes and minimizes wasted current in series-connected configurations. |
| DO-15 mechanical standard | Ensures compatibility with legacy through-hole assembly lines and automated insertion equipment. |
Applications
| AC/DC Wall Adapters | Industrial Control Power Supplies |
|---|---|
Use Scenario: Rectifying 50/60Hz AC from step-down transformers in Class II isolated adapters delivering 5–24V DC. IC Role / Device Role / Timing Role: Primary unidirectional current path converting AC to pulsating DC prior to filtering and regulation. Use Value: Low VFM (1.1V) minimizes conduction loss at 1.5A output; DO-15 footprint simplifies manual or automated assembly in cost-sensitive consumer designs. | Use Scenario: Providing auxiliary 12V or 24V DC rails for PLC I/O modules, relay drivers, and sensor interface circuitry. IC Role / Device Role / Timing Role: Discrete rectifier in linear or hybrid power stages where high reliability and surge tolerance are mandatory. Use Value: 50A IFSM handles motor startup surges and inductive kickback; 175°C max junction temperature supports operation in enclosed industrial enclosures. |
| LED Driver Input Stages | Legacy Appliance Power Conversion |
Use Scenario: Full-wave or half-wave rectification in constant-current LED driver front-ends operating from mains-derived AC. IC Role / Device Role / Timing Role: Discrete bridge or single-diode element in low-cost, non-isolated LED power topologies. Use Value: 100V VRRM safely accommodates 120VAC peak (170V) with margin; low CT (15pF) avoids high-frequency noise coupling into sensitive current regulation loops. | Use Scenario: Replacing aging rectifiers in refrigerators, washing machines, and HVAC control boards with 50/60Hz transformer inputs. IC Role / Device Role / Timing Role: General-purpose replacement diode in maintenance and repair contexts requiring DO-15 form factor and proven thermal stability. Use Value: RoHS-compliant tin finish ensures compatibility with modern rework processes; -65°C to +175°C operating range exceeds appliance environmental 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 |
|---|---|---|---|
| 1N4002GP-E3/54 (Vishay) | Same DO-41 package, 100V VRRM, but higher VFM (1.1V @ 1A vs. 1.1V @ 1.5A); 1A IO rating. | Limited to ≤1A average current; unsuitable for sustained 1.5A loads without derating. | Select only when board space allows DO-41 and current demand is ≤1A. |
| RS1M (ON Semiconductor) | DO-15, 1000V VRRM, 1A IO, faster recovery (~500ns), lower IR (≤5µA). | Over-specified reverse voltage; lower current rating requires parallel configuration for 1.5A. | Choose only if high-voltage margin or fast recovery is prioritized over cost and current capacity. |
Compared with 1N4002GP-E3/54 and RS1M, the 1N5392G-T delivers higher continuous current (1.5A vs. 1A), matched DO-15 packaging, and verified thermal performance at full load-making it optimal for cost-sensitive, medium-current rectification where VRRM ≤100V suffices.

FAQ
Is the 1N5392G-T suitable for capacitive-load applications?
No-it is explicitly derated by 20% for capacitive loads per the datasheet. At full 1.5A rating, it must be used only with resistive or inductive loads. For capacitor-input filters, maximum continuous current drops to 1.2A to ensure reliability and prevent premature failure due to high peak currents.
What is the meaning of "NOT RECOMMENDED FOR NEW DESIGN" in the datasheet?
This designation indicates Diodes Incorporated no longer promotes the 1N5392G-T for newly initiated projects due to newer alternatives with improved efficiency or packaging. However, it remains fully manufactured, stocked, and supported for existing designs, repairs, and legacy production with no announced obsolescence date.
Can the 1N5392G-T replace a 1N4002 in an existing design?
Yes-both are 100V general-purpose rectifiers in axial packages, but the 1N5392G-T uses DO-15 (larger body, higher thermal mass) versus DO-41. Mechanical fit must be verified; electrically, it offers higher current (1.5A vs. 1A) and identical VRRM, making it a functional upgrade if board layout permits.
Does the 1N5392G-T meet RoHS requirements?
Yes-the "-T" suffix denotes tape-and-reel packaging with lead-free, RoHS-compliant matte tin plating on leads. It complies with EU Directive 2011/65/EU, including exemptions for high-temperature solder and glass content as noted in the datasheet's Note 3.
