Product details
Overview
1N4003GL-T from Diodes Incorporated is a glass-passivated silicon rectifier diode rated for 200 V peak repetitive reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current, with 1.0 V forward voltage at 1.0 A. It serves as a general-purpose AC-to-DC power supply input rectifier in low-frequency linear power supplies, battery chargers, and DC adapter circuits.
For engineers reviewing the 1N4003GL-T datasheet, 1N4003GL-T pinout, 1N4003GL-T application, or 1N4003GL-T equivalent, key selection criteria include its 200 V blocking rating, DO-41 package thermal resistance (100 °C/W), 2.0 µs reverse recovery time, and RoHS-compliant tin-plated leads suitable for automated assembly.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz resistive or inductive loads. Its glass-passivated die construction ensures stable junction performance and enhanced moisture resistance versus epoxy-passivated variants.
Rated for operation from –65 °C to +175 °C, it exhibits 5.0 µA peak reverse leakage at 25 °C and 50 µA at 125 °C under full DC blocking voltage, with typical junction-to-ambient thermal resistance of 100 °C/W when leads are held at ambient temperature at 9.5 mm from case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage the diode blocks without breakdown; defines usable AC input range in bridge or half-wave rectifiers. |
| IO @ TA=75°C | 1.0 A - Continuous average forward current capability at 75 °C ambient; derates to ~0.7 A at 100 °C per Fig. 1. |
| IFSM | 30 A - Non-repetitive surge current tolerance for 8.3 ms half-sine; supports inrush limiting in transformer-coupled supplies. |
| VFM @ IF=1.0A | 1.0 V - Forward voltage drop at rated DC output current; determines conduction loss and thermal load in rectification stage. |
| trr | 2.0 µs - Reverse recovery time measured at IF=0.5A, IR=–1A, Irr=0.25A; suitable for 60/50 Hz line-frequency applications only. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance with leads at ambient; requires PCB copper area or heatsinking for sustained 1 A operation above 75 °C. |
| CT @ 1 MHz, 4 V | 8.0 pF - Junction capacitance under reverse bias; negligible impact on 50/60 Hz filtering but relevant for EMI filter design. |
Pinout & Package
Package: DO-41 plastic case (UL 94V-0), axial leaded, cathode indicated by band. Dimensions: A = 25.40 mm max length, B = 4.06–5.21 mm body diameter, C = 0.71–0.864 mm lead diameter, D = 2.00–2.72 mm lead spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary during positive half-cycle; must withstand surge and steady-state current. |
| Cathode | Forward current exit point | Connected to filter capacitor or load; marked with band; polarity critical for correct rectification direction. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Enhanced junction stability and humidity resistance vs. epoxy-passivated equivalents; extends operational life in humid environments. |
| 30 A surge rating | Withstands transformer inrush and capacitor charging surges without failure; enables robust front-end protection in unregulated supplies. |
| RoHS-compliant tin plating | Lead finish meets MIL-STD-202 Method 208 solderability requirements; compatible with lead-free reflow and wave soldering processes. |
| –65 °C to +175 °C operation | Wide temperature envelope supports use in automotive under-hood, industrial controls, and outdoor power equipment. |
Applications
| AC/DC Wall Adapters | Industrial Control Power Supplies |
|---|---|
Use Scenario: Converts 120/230 VAC mains to unregulated DC for low-power logic rails in consumer adapters. IC Role / Device Role / Timing Role: Primary rectifier in single-phase half-wave or center-tapped transformer configuration. Use Value: 200 V VRRM safely handles 120 VAC RMS with margin; 1.0 V VFM limits conduction loss in compact, thermally constrained enclosures. | Use Scenario: Provides auxiliary 24 VDC bias for PLC I/O modules and relay drivers in factory automation cabinets. IC Role / Device Role / Timing Role: Input-stage rectifier feeding bulk capacitor and linear regulator or buck converter. Use Value: 30 A IFSM tolerates repeated motor contactor switching transients; DO-41 package fits standard PCB footprints. |
| Battery Charger Circuits | LED Driver Input Stages |
Use Scenario: Rectifies transformer output in constant-voltage NiCd/NiMH charger designs with current-limiting resistor or series transistor. IC Role / Device Role / Timing Role: Unidirectional current path enabling capacitor charging during positive half-cycles. Use Value: Low 1.0 V forward drop preserves available headroom for regulation; 5 µA IR at 25 °C minimizes standby leakage. | Use Scenario: Front-end rectification in isolated LED drivers using flyback topology with low-cost discrete control. IC Role / Device Role / Timing Role: Mains-side AC input rectifier before primary-side energy storage and switching stage. Use Value: Glass passivation ensures long-term reliability under thermal cycling; UL 94V-0 housing meets basic safety compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4003G-T (Diodes Inc.) | Same electrical specs and DO-41 package; differs only in marking (no 'L') and tape/reel packaging detail. | No functional difference; identical thermal, surge, and blocking performance. | Select when standard tape-and-reel logistics are preferred over legacy GL-T labeling. |
| STTH1R02 (STMicroelectronics) | Fast recovery (trr ≈ 1.5 µs), same 200 V/1 A rating, but TO-220AC package (higher RθJA ≈ 65 °C/W). | Higher thermal mass and mounting flexibility; not direct footprint replacement. | Choose for higher surge repetition or improved thermal management where board space allows TO-220 mounting. |
Compared with 1N4003G-T, the 1N4003GL-T offers identical electrical behavior and mechanical form; versus STTH1R02, it trades faster recovery and thermal performance for lower cost and DO-41 footprint compatibility in space-constrained designs.

FAQ
What is the maximum operating temperature for 1N4003GL-T?
The 1N4003GL-T has an operating junction temperature range of –65 °C to +175 °C. Its safe continuous operation depends on thermal management: at 75 °C ambient, it supports 1.0 A average forward current; above that, current must be derated per Figure 1 in the datasheet, reaching ~0.7 A at 100 °C ambient.
Is 1N4003GL-T suitable for high-frequency switching applications?
No. With a typical reverse recovery time of 2.0 µs and no fast-recovery optimization, the 1N4003GL-T is intended only for 50/60 Hz line-frequency rectification. Using it in switch-mode power supplies (>1 kHz) causes excessive switching losses, overheating, and potential failure due to slow turn-off characteristics.
How does the 'GL' suffix differ from 'G' in Diodes Incorporated part numbers?
The 'GL' suffix denotes glass-passivated construction with specific tape-and-reel packaging (5K per reel, 13-inch reel) and RoHS-compliant tin plating. The 'G' variant shares identical electrical and thermal specs but may differ in packaging format or marking-both meet the same DO-41 mechanical and performance standards per DS29002 Rev. 8-2.
Can 1N4003GL-T replace 1N4001G-T in a 50 V circuit?
Yes-electrically and mechanically. The 1N4003GL-T has a higher 200 V peak reverse voltage rating than the 1N4001G-T (50 V), making it a safe, drop-in upgrade in any 50 V application. No circuit modification is needed, and it provides additional margin against voltage transients and aging-related degradation.
