Product details
Overview
1N4001GPHE3/73 from Vishay General Semiconductor is a glass-passivated junction plastic rectifier diode rated for 50 V repetitive peak reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current. It features low forward voltage (1.1 V at 1.0 A), low leakage (5.0 μA at 25 °C), and operates from –65 °C to +175 °C - used in AC/DC power supply input rectification and freewheeling paths.
For engineers reviewing the 1N4001GPHE3/73 datasheet, 1N4001GPHE3/73 pinout, 1N4001GPHE3/73 application, or 1N4001GPHE3/73 equivalent, key selection criteria include VRRM = 50 V, IF(AV) = 1.0 A, thermal resistance RθJA = 55 °C/W, DO-41 package compatibility, and suitability for low-cost, high-reliability general-purpose rectification.
Technical Context
This device implements a single silicon p–n junction with cavity-free glass passivation, enabling stable performance under thermal cycling and humidity exposure. Its Superectifier® structure improves reliability over standard epoxy-passivated diodes while maintaining JEDEC DO-41 mechanical compliance.
Designed for line-frequency (50/60 Hz) rectification, it delivers typical reverse recovery time of 2.0 μs and junction capacitance of 8.0 pF at 4.0 V - parameters critical for minimizing switching losses in low-speed power conversion and reducing EMI in consumer-grade supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse blocking voltage; defines safe AC input peak handling in bridge or half-wave rectifiers |
| IF(AV) | 1.0 A at 75 °C with 0.375" lead length - continuous DC output capability for low-power adapters and wall transformers |
| VF | 1.1 V at 1.0 A - low conduction loss reduces heat generation and improves efficiency in linear power stages |
| IR | 5.0 μA at 25 °C - minimal leakage preserves hold-up time in capacitor-input filters and prevents unintended discharge |
| IFSM | 30 A (8.3 ms sine) - withstands inrush surges during cold-start of power supplies without degradation |
| TJ(max) | +175 °C - enables operation in thermally constrained enclosures or near heat-generating components |
| RθJA | 55 °C/W - thermal resistance determines required heatsinking or PCB copper area for sustained 1 A operation |
Pinout & Package
Package: DO-41 (DO-204AL), molded epoxy over glass body; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or inductive load return path; must handle full surge current and thermal dissipation |
| Cathode | Forward current exit point | Marked with color band; ties to positive rail or snubber node; polarity reversal causes catastrophic failure |
Key Features
| Feature | Design Value |
|---|---|
| Superectifier® structure | Enhanced reliability via cavity-free glass passivation - eliminates moisture ingress paths and interfacial delamination risks |
| Low leakage current | 5.0 μA max at 25 °C - maintains filter capacitor charge in standby mode and reduces no-load power loss |
| High surge rating | 30 A IFSM (8.3 ms) - accommodates transformer inrush and motor startup transients without derating |
| Solderability | Rated for 275 °C / 10 s dip soldering per JESD 22-B106 - supports wave and selective soldering in high-volume assembly |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker test - ensures long-term lead integrity in humid or high-vibration environments |
Applications
| AC/DC Wall Adapters | LED Driver Input Stage |
|---|---|
Use Scenario: Rectifying 120/230 VAC mains into unregulated DC for low-power isolated flyback converters. IC Role / Device Role / Timing Role: Primary-side rectifier in voltage-doubler or bridge configuration; conducts only during positive half-cycles. Use Value: 50 V VRRM safely handles 120 VAC peak (170 V) with margin; 1.1 V VF limits conduction loss in <10 W designs. | Use Scenario: Converting rectified AC to DC before constant-current regulation in off-line LED drivers. IC Role / Device Role / Timing Role: Input-stage freewheeling diode across transformer primary or boost inductor. Use Value: 30 A IFSM absorbs inductive kickback energy; 175 °C TJ(max) supports compact enclosure thermal design. |
| Consumer Audio Power Supplies | Small Appliance Control Boards |
Use Scenario: Providing dual-polarity rails for op-amp biasing in analog audio amplifiers and DAC circuits. IC Role / Device Role / Timing Role: Half-wave rectifier feeding center-tapped transformer secondary; paired with smoothing capacitors. Use Value: Low 5.0 μA IR prevents capacitor self-discharge between cycles - preserving rail stability during signal pauses. | Use Scenario: Rectifying low-voltage AC from control transformers powering microcontroller logic and relay coils. IC Role / Device Role / Timing Role: Output-side rectifier delivering 12–24 VDC to embedded controllers and solenoid drivers. Use Value: DO-41 package fits standard through-hole footprints; RoHS-compliant E3 finish meets global manufacturing 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 |
|---|---|---|---|
| 1N4001G-E3/54 (Vishay) | Same electrical specs; differs only in packaging - tape-and-reel (54) vs. ammo pack (73); identical DO-41 body and plating | No functional difference; choice depends on SMT line feed method and order quantity | Select 1N4001G-E3/54 for automated pick-and-place; retain 1N4001GPHE3/73 for manual or semi-automated assembly requiring smaller reels |
| 1N4001 (ON Semiconductor) | VRRM = 50 V, IF(AV) = 1.0 A, VF = 1.1 V - matches core ratings; uses standard epoxy passivation instead of glass | Lower moisture resistance and reduced long-term reliability in humid environments versus glass-passivated 1N4001GPHE3/73 | Choose 1N4001GPHE3/73 where extended field life or elevated temperature operation is required; use ON Semi 1N4001 only for cost-sensitive, short-lifecycle consumer goods |
Compared with 1N4001G-E3/54, the 1N4001GPHE3/73 offers identical performance in a different packaging format; compared with ON Semiconductor's 1N4001, it provides superior environmental robustness due to cavity-free glass passivation - critical for industrial or outdoor-rated equipment.

FAQ
What is the maximum junction temperature rating for the 1N4001GPHE3/73?
The 1N4001GPHE3/73 has a maximum operating junction temperature of +175 °C, allowing reliable operation in thermally demanding environments such as enclosed power supplies or proximity to heat-generating components. This rating is specified in the Vishay datasheet Document Number 88504 and verified under JEDEC conditions. Thermal design must account for RθJA = 55 °C/W to avoid exceeding this limit at full 1.0 A load.
Is the 1N4001GPHE3/73 RoHS-compliant?
Yes, the 1N4001GPHE3/73 is RoHS-compliant per EU Directive 2011/65/EU, confirmed by its "E3" suffix and compliance with JESD 201 Class 1A whisker testing. The matte tin-plated leads meet J-STD-002 solderability standards, and the molding compound satisfies UL 94 V-0 flammability requirements. Full compliance documentation is available from Vishay upon request.
What does the "HE3/73" suffix mean in 1N4001GPHE3/73?
The "HE3/73" suffix identifies the packaging and plating: "H" denotes glass passivation, "E3" indicates RoHS-compliant matte tin plating meeting JESD 201 Class 1A, and "73" specifies ammo pack packaging with 3000 units per pack. This distinguishes it from tape-and-reel variants like "E3/54". The base part number 1N4001GP remains functionally identical across suffixes.
Can the 1N4001GPHE3/73 be used in place of the 1N4007GP?
No - the 1N4001GPHE3/73 is rated for 50 V VRRM, whereas the 1N4007GP supports 1000 V. Substituting them risks immediate reverse breakdown in high-voltage applications. They share the same DO-41 package and forward characteristics, but reverse voltage capability is not interchangeable. Always match VRRM to the circuit's peak reverse stress.
What is the typical reverse recovery time of the 1N4001GPHE3/73?
The 1N4001GPHE3/73 has a typical reverse recovery time (trr) of 2.0 μs when tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is measured per standard conditions in the Vishay datasheet and reflects its suitability for 50/60 Hz rectification - not high-frequency switching. Faster recovery diodes are required for SMPS operation above 20 kHz.
