Product details
Overview
1N4001GL-T from Diodes Incorporated is a glass-passivated silicon rectifier diode in DO-41 package, rated for 50 V peak repetitive reverse voltage, 1.0 A average forward current at 75°C, and 30 A non-repetitive surge current. It delivers 1.0 V forward voltage at 1.0 A and exhibits 5.0 µA peak reverse current at 25°C, used in AC/DC power supplies, adapter circuits, and low-voltage DC power conversion.
For engineers reviewing the 1N4001GL-T datasheet, 1N4001GL-T pinout, 1N4001GL-T application, or 1N4001GL-T equivalent, key selection criteria include reverse voltage margin, thermal derating behavior, surge robustness under line transients, and compatibility with automated tape-and-reel SMT placement (5K/reel, 13-inch).
Technical Context
This device operates as a single-phase, half-wave rectifier under 60 Hz resistive or inductive loads. Its glass-passivated junction ensures stable leakage performance and enhanced moisture resistance versus epoxy-passivated variants.
Thermal resistance is 100°C/W junction-to-ambient (with leads held at ambient 9.5 mm from case), and reverse recovery time is 2.0 µs-suitable for line-frequency applications but not high-frequency switching. Capacitance is 8.0 pF at 1 MHz and 4.0 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking capability without breakdown |
| IO @ TA=75°C | 1.0 A - Continuous DC output current with thermal derating above ambient |
| IFSM | 30 A - Peak surge withstand for 8.3 ms half-sine, critical for inrush protection |
| VFM @ IF=1.0A | 1.0 V - Forward conduction loss impacting efficiency and thermal rise |
| IRM @ 25°C | 5.0 µA - Low leakage ensures minimal standby power loss in off-state |
| trr | 2.0 µs - Reverse recovery speed adequate for 50/60 Hz, not for kHz+ SMPS |
| RθJA | 100 °C/W - Thermal limit defines PCB copper area and airflow requirements |
Pinout & Package
DO-41 plastic axial-leaded package with cathode band marking; body diameter 2.00–2.72 mm, length 4.06–5.21 mm, lead diameter 0.71–0.864 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary during positive half-cycle |
| Cathode | Forward current exit point | Marked with band; ties to load/positive rail; reverse-biased during negative half-cycle |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Superior environmental stability vs. epoxy; meets J-STD-020 Level 1 moisture sensitivity |
| RoHS-compliant tin-plated leads | Solderable per MIL-STD-202 Method 208; supports lead-free reflow profiles |
| 30 A surge rating | Withstands cold-start inrush in transformer-based supplies without failure |

Applications
| AC/DC Wall Adapters | Industrial Control Power Supplies |
|---|---|
Use Scenario: Converts 120/230 VAC mains to low-voltage DC for consumer electronics. IC Role / Device Role / Timing Role: Rectifier in bridge or half-wave configuration feeding capacitor-input filter. Use Value: 50 V VRRM provides sufficient margin over 170 V peak of 120 VAC; 30 A IFSM handles transformer saturation surges. | Use Scenario: Provides isolated +5 V or +24 V bias for PLC I/O modules and relay drivers. IC Role / Device Role / Timing Role: Input-stage rectifier in linear or hybrid regulated supply with choke-input filtering. Use Value: Low IRM (5 µA) minimizes no-load leakage; DO-41 axial form enables through-hole mounting on rugged control boards. |
| Automotive Aftermarket Chargers | LED Driver Input Stages |
Use Scenario: Rectifies alternator output or AC input in portable 12 V battery chargers. IC Role / Device Role / Timing Role: Half-wave rectifier feeding smoothing capacitor and linear regulator. Use Value: -65°C to +175°C operating range supports under-hood thermal cycling; glass passivation resists underhood humidity. | Use Scenario: Converts AC line to DC bus prior to constant-current LED driver IC. IC Role / Device Role / Timing Role: Primary rectifier in non-isolated buck-derived LED drivers. Use Value: 1.0 V VFM limits conduction loss in low-output-voltage designs; 8.0 pF CT avoids EMI coupling at line frequency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4001-T | Same electrical specs; epoxy-passivated die instead of glass | Lower moisture resistance; not rated to J-STD-020 Level 1 | Select when cost sensitivity outweighs humidity exposure risk |
| 1N4001G | Identical specs and construction; differs only in packaging (bulk vs. tape-and-reel) | No functional difference; same DO-41 mechanical outline and marking | Choose for manual prototyping or small-batch hand assembly |
Compared with 1N4001-T and 1N4001G, the 1N4001GL-T offers identical rectification performance with certified RoHS compliance, glass passivation for reliability in humid environments, and tape-and-reel format optimized for automated production throughput.

FAQ
Is 1N4001GL-T suitable for high-frequency switching applications?
No. With a 2.0 µs reverse recovery time and no specified switching speed optimization, it is designed exclusively for 50/60 Hz line-frequency rectification. Using it in kHz-range SMPS causes excessive switching loss, heating, and potential failure. Select fast-recovery or ultrafast diodes like UF4007 for such applications.
What does the "L" suffix in 1N4001GL-T signify?
The "L" denotes Diodes Incorporated's internal revision level for the glass-passivated die process and final test flow. It reflects updated wafer fabrication controls and screening-confirmed by DS29002 Rev. 8-2-but does not alter electrical specifications, package dimensions, or pinout versus earlier 1N4001G-T versions.
Can 1N4001GL-T replace 1N4007GL-T in a circuit?
No. The 1N4001GL-T has only 50 V VRRM versus 1000 V for the 1N4007GL-T. Substitution risks catastrophic reverse breakdown in circuits exposed to >50 V peak reverse voltage, such as capacitor-input filters on 230 VAC lines. Always match VRRM to worst-case circuit stress.
Does this diode require heatsinking in standard operation?
Not typically. At 1.0 A and 1.0 V forward drop, power dissipation is 1.0 W. With RθJA = 100°C/W and TA = 75°C, junction temperature rises ~100°C above ambient-reaching ~175°C, the absolute maximum. Derating or minimal copper pour is advised for sustained full-load operation; heatsinking becomes necessary above 750 mA in enclosed or high-ambient environments.
