Product details
Overview
1N5395G-T from Diodes Incorporated is a 1.5A, 400V glass passivated general-purpose rectifier diode in DO-15 package, featuring low forward voltage drop (1.1V @ 1.5A), 50A non-repetitive surge capability, and <5.0µA reverse leakage at 25°C - used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the 1N5395G-T datasheet, 1N5395G-T pinout, 1N5395G-T application, or 1N5395G-T equivalent, key selection criteria include peak repetitive reverse voltage (400V), average forward current derating above 55°C, thermal resistance (80°C/W), and DO-15 mechanical compatibility with through-hole PCB layouts.
Technical Context
This axial-lead rectifier operates in single-phase, half-wave configurations with resistive or inductive loads at 60Hz; capacitive loads require 20% current derating. Its glass passivated die ensures stable junction performance across -65°C to +175°C operating range.
The device exhibits typical junction capacitance of 15pF at 1MHz/4V reverse bias and I²t fusing rating of 10.4A²s for transient surge protection. Thermal resistance from junction to ambient is 80°C/W under standard lead conditions (9.5mm from case).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak repetitive reverse voltage the diode blocks without breakdown in normal operation. |
| IO @ TA=55°C | 1.5 A - Continuous average forward current rating when ambient temperature is held at 55°C with leads at ambient. |
| VFM @ IF=1.5A | 1.1 V - Forward voltage drop at rated DC output current, directly impacting conduction loss and thermal design. |
| IFSM | 50 A - Non-repetitive peak forward surge current tolerance for 8.3ms half-sine waveform, critical for inrush handling. |
| IRM @ 25°C | 5.0 µA - Reverse leakage current at rated DC blocking voltage, affecting standby power and high-impedance circuit integrity. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance under specified mounting condition, used to calculate junction temperature rise. |
| CT @ 1MHz | 15 pF - Junction capacitance at 4V reverse bias, influencing high-frequency switching noise and EMI filtering requirements. |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0), axial-leaded, cathode indicated by band. Weight ≈ 0.4 g. Moisture sensitivity level 1 per J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary during positive half-cycle; determines polarity-sensitive PCB layout orientation. |
| Cathode | Forward current exit point | Marked with band; ties to output capacitor or load return; defines DC output polarity in bridge or half-wave rectifier topologies. |
Key Features

Applications
| AC/DC Power Adapter Input Rectification | LED Driver Bulk Rectification |
|---|---|
Use Scenario: Converts 120/230VAC mains to pulsating DC before bulk capacitor smoothing in low-cost offline LED drivers. IC Role / Device Role / Timing Role: General-purpose rectifier performing half-wave or full-wave (in bridge) conversion; no timing function. Use Value: 400V VRRM safely handles 230VAC line peaks (≈325V) with margin; 1.5A IO supports up to 15W output at 85–265VAC input. |
Use Scenario: Rectifies transformer-coupled AC output in isolated constant-current LED driver designs for street lighting. IC Role / Device Role / Timing Role: Discrete power diode providing unidirectional current path; operates at line frequency only. Use Value: Low 1.1V VF minimizes heat generation near sensitive LED strings; DO-15 footprint simplifies manual repair and field replacement. |
| Industrial Control Power Supply Front-End | Appliance Motor Drive Auxiliary Supply |
Use Scenario: Supplies unregulated DC to linear regulators powering microcontrollers and sensors in PLC I/O modules. IC Role / Device Role / Timing Role: Primary rectification element in low-noise auxiliary supply; no signal conditioning role. Use Value: 5.0µA IRM at 25°C prevents excessive standby drain on backup capacitors; -65°C to +175°C rating suits wide-temperature enclosures. |
Use Scenario: Provides DC bias for gate drivers and logic in washing machine motor inverters using discrete IGBTs. IC Role / Device Role / Timing Role: Off-line rectifier feeding small reservoir capacitor; operates synchronously with 50/60Hz mains. Use Value: 50A IFSM withstands compressor startup surges; glass passivation resists condensation-induced leakage in humid laundry environments. |
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 | 1000V VRRM, 1.1V VF @ 1A, 30A IFSM, same DO-15 package | Higher voltage rating but lower surge and current capability; less suitable for 230VAC systems with high inrush | Select when >600V blocking is required and 1.5A continuous current is not needed. |
| 1N5395RLG | Identical electrical specs; leaded (not tape-and-reel), RoHS-compliant, same DO-15 package | No functional difference; differs only in packaging format and reel logistics | Choose for hand-soldering, prototyping, or low-volume production where tape-and-reel is unnecessary. |
Compared with 1N4007-T, the 1N5395G-T offers higher continuous current (1.5A vs 1.0A) and superior surge resilience (50A vs 30A) at lower voltage rating - ideal for cost-sensitive 230VAC inputs. Versus 1N5395RLG, it provides identical performance with optimized logistics for automated SMT placement.

FAQ
Is the 1N5395G-T suitable for use in a full-wave bridge rectifier configuration?
Yes - the 1N5395G-T is commonly used in discrete full-wave bridge rectifiers due to its 400V peak reverse voltage rating, which exceeds the 325V peak of 230VAC mains. Four units can be assembled into a bridge with proper cathode/anode orientation; thermal derating must be applied per the datasheet's Fig. 1 curve when ambient exceeds 55°C.
What is the maximum allowable PCB pad temperature during soldering?
The device's tin-plated leads comply with MIL-STD-202 Method 208 and support standard wave and reflow profiles. Peak solder temperature must not exceed 260°C for ≤10 seconds during hand or wave soldering; for reflow, follow JEDEC J-STD-020C Level 1 profile with peak at 245°C max and time above liquidus ≤60 seconds.
Does the "NOT RECOMMENDED FOR NEW DESIGN" notice affect existing production?
No - the notice indicates Diodes recommends newer alternatives (e.g., high-efficiency Schottky or fast recovery diodes) for new designs, but the 1N5395G-T remains fully qualified, in active production, and supported for legacy and cost-driven applications where its performance and DO-15 footprint meet requirements.
How does thermal resistance change if leads are trimmed close to the case?
Trimming leads within 9.5mm of the DO-15 case increases RθJA beyond the rated 80°C/W, potentially raising junction temperature by 15–25°C at full load. Maintain ≥9.5mm lead length between PCB surface and case for published thermal performance; use heatsinking or airflow if shorter leads are unavoidable.
