Product details
Overview
1N4001GPEHE3/73 from Vishay General Semiconductor is a glass-passivated junction plastic rectifier diode in DO-41 package, rated for 50 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 30 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (1.1 V at 1.0 A) and low leakage current (5.0 μA at 25 °C), suited for AC/DC power supply input rectification in consumer electronics.
For engineers reviewing the 1N4001GPEHE3/73 datasheet, 1N4001GPEHE3/73 pinout, 1N4001GPEHE3/73 application, or 1N4001GPEHE3/73 equivalent, key selection criteria include VRRM = 50 V, IF(AV) = 1.0 A, thermal resistance RθJA = 55 °C/W, trr = 2.0 μs, and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device implements a single silicon p-n junction with cavity-free glass passivation, enabling stable operation up to 175 °C junction temperature and high reliability in thermally stressed environments. Its Superectifier® structure minimizes leakage and improves surge robustness without requiring external snubbers in basic rectifier configurations.
The diode operates as a unidirectional current path with cathode indicated by a color band; it exhibits typical junction capacitance of 8.0 pF at 4.0 V / 1 MHz and transient thermal impedance optimized for pulsed-load applications such as line-frequency half-wave rectification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum allowable reverse voltage before breakdown; defines safe operating limit in 50–60 Hz AC input stages |
| IF(AV) | 1.0 A - continuous DC output current capability at 75 °C ambient with 0.375" lead length; sets minimum heatsinking requirement |
| VF | 1.1 V @ 1.0 A - forward conduction loss determines power dissipation (1.1 W typical) and efficiency in low-voltage supplies |
| IR | 5.0 μA @ 25 °C - reverse leakage ensures minimal standby power loss in off-state circuits |
| trr | 2.0 μs - reverse recovery time supports operation up to ~100 kHz switching in freewheeling roles, but not for high-frequency SMPS |
| RθJA | 55 °C/W - thermal resistance from junction to ambient; used to calculate max junction temp rise under given power dissipation |
| TJ(max) | 175 °C - maximum allowable junction temperature; enables use in enclosed or high-ambient industrial enclosures |

|---|---|
Use Scenario: Converting 120 VAC mains to unregulated DC in wall adapters and small appliance power supplies. IC Role / Device Role / Timing Role: Primary rectifier conducting during positive half-cycles; blocks reverse voltage during negative half-cycles. Use Value: 50 V VRRM provides sufficient margin over 120 VAC peak (≈170 V), while 1.0 A rating supports typical <15 W output loads. | Use Scenario: Suppressing inductive kickback when de-energizing 12 V DC relays or solenoids in control panels. IC Role / Device Role / Timing Role: Provides low-impedance return path for stored coil energy, clamping voltage spike to ~1.1 V above rail. Use Value: 30 A IFSM safely absorbs short-duration flyback surges; 2.0 μs trr prevents oscillation in moderate-speed switching. |
| Inverter DC Bus Protection | DC Power Rail Reverse Polarity Protection |
Use Scenario: Blocking reverse current flow from battery backup into main DC bus during grid outage in solar microinverters. IC Role / Device Role / Timing Role: Unidirectional isolation element placed in series with battery feed; conducts only during normal discharge mode. Use Value: 175 °C TJ(max) ensures stability under sustained bus voltage stress; low VF minimizes insertion loss in high-current paths. | Use Scenario: Preventing damage from accidental reverse connection of 5–24 V DC power supplies to embedded controllers or sensors. IC Role / Device Role / Timing Role: Series protection diode placed between input connector and system rail; blocks reverse polarity while passing forward current. Use Value: 1.0 A IF(AV) supports common sensor/module current draws; DO-41 footprint allows easy retrofit on existing boards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4001-T | VRRM = 50 V, same IF(AV), but epoxy-passivated (not glass); RθJA ≈ 60 °C/W | Slightly higher thermal resistance and lower humidity resistance; less suitable for high-reliability outdoor deployments | Select when cost sensitivity outweighs long-term environmental robustness requirements |
| 1N4001G | Identical electrical specs and glass passivation, but lacks E3 RoHS compliance and JESD 201 whisker testing | Not qualified for lead-free reflow or high-reliability commercial production; limited to legacy repair or prototyping | Choose only for non-RoHS legacy systems where tin whisker risk is mitigated by design controls |
Compared with 1N4001-T and 1N4001G, the 1N4001GPEHE3/73 offers superior moisture resistance via cavity-free glass passivation, verified RoHS compliance (E3), and tighter thermal performance (RθJA = 55 °C/W), making it preferred for new commercial designs requiring traceable sourcing and extended lifecycle support.

FAQ
What is the maximum junction temperature rating for the 1N4001GPEHE3/73?
The 1N4001GPEHE3/73 has a maximum junction temperature (TJ(max)) of +175 °C. This rating allows reliable operation in enclosed or high-ambient-temperature environments such as sealed power supplies or industrial control cabinets. Derating curves in the Vishay datasheet (Document Number 88504) specify usable current limits at elevated ambient temperatures, and the device maintains specified electrical characteristics up to this thermal limit.
Is the 1N4001GPEHE3/73 suitable for new designs despite Vishay's "Not for New Designs" notice?
While Vishay labels the 1N4001GPEHE3/73 as "Not for New Designs" in its 2022 datasheet revision, Aetrix Electronics confirms ongoing availability and full lifecycle support for this part. It remains appropriate for cost-sensitive, low-frequency rectification applications where qualification timelines preclude newer alternatives, and where DO-41 footprint compatibility and proven field reliability are prioritized over next-generation efficiency metrics.
What does the "E3/73" suffix mean in 1N4001GPEHE3/73?
The "E3" suffix indicates RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "73" denotes ammo pack packaging containing 3000 units. The full designation 1N4001GPEHE3/73 identifies a specific ordering variant-glass-passivated, RoHS-compliant, 3000-unit ammo pack-with identical electrical and thermal specs as other 1N4001GP variants.
How does the reverse recovery time of the 1N4001GPEHE3/73 affect its use in switching circuits?
The 1N4001GPEHE3/73 has a typical reverse recovery time (trr) of 2.0 μs. This limits its suitability to line-frequency (50/60 Hz) and low-frequency (<10 kHz) applications such as transformer-based power supplies or relay freewheeling. It is not recommended for high-frequency switch-mode power supplies (SMPS) above 20 kHz, where faster recovery diodes (e.g., UF4001 or MUR series) would minimize switching losses and EMI.
Can the 1N4001GPEHE3/73 be used in parallel to increase current handling?
No-parallel operation of 1N4001GPEHE3/73 diodes is not recommended due to forward voltage mismatch causing current imbalance. Even minor VF variations (±0.05 V) can result in one diode carrying >70% of total current, risking thermal runaway. For higher current needs, select a single higher-rated rectifier (e.g., 1N5401) or verify matched VF binning with Vishay's factory test data before parallel implementation.
