Product details
Overview
1N4384GPHE3/54 from Vishay General Semiconductor is a glass-passivated junction plastic rectifier diode in DO-15 package, rated for 400 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 50 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (1.0 V at 1.0 A) and ultra-low leakage (5.0 µA at 25 °C), suited for power supply input rectification and freewheeling in industrial DC-DC converters.
For engineers reviewing the 1N4384GPHE3/54 datasheet, 1N4384GPHE3/54 pinout, 1N4384GPHE3/54 application, or 1N4384GPHE3/54 equivalent, key selection criteria include VRRM = 400 V, IF(AV) = 1.0 A, trr = 2.0 µs, RθJA = 45 °C/W, and DO-15 mechanical compatibility with legacy through-hole power designs.
Technical Context
This device implements a single silicon PN 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 reverse recovery charge and supports fast switching in line-frequency and medium-frequency rectification circuits.
Electrical behavior is defined by JEDEC-standard DO-15 thermal and electrical ratings: 45 °C/W junction-to-ambient thermal resistance (at 0.375" lead length), 2.0 µs typical reverse recovery time under 0.5 A forward / 1.0 A reverse test conditions, and 15 pF junction capacitance at 4.0 V / 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage; defines safe AC input voltage derating limit for bridge or half-wave rectifiers |
| IF(AV) | 1.0 A - continuous DC output current capability at 100 °C ambient with 0.375" lead length; sets minimum heatsinking requirement |
| IFSM | 50 A - peak surge current tolerance for 8.3 ms half-sine; determines robustness against line transients and inrush events |
| VF | 1.0 V @ 1.0 A - forward conduction loss at rated DC load; directly impacts power dissipation and efficiency in linear supplies |
| trr | 2.0 µs - reverse recovery time; enables use in 20–50 kHz flyback snubber and freewheeling paths without excessive switching loss |
| RθJA | 45 °C/W - thermal resistance from junction to ambient; used to calculate max allowable power dissipation at target TJ |
| CJ | 15 pF @ 4 V, 1 MHz - junction capacitance; affects EMI generation and high-frequency noise coupling in switching nodes |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy over glass body; UL 94 V-0 rated; 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 switch node; must withstand full IFSM during surge events |
| Cathode | Forward current exit point | Marked by color band; ties to positive rail or inductor return; carries full IF(AV) continuously |
Key Features
| Feature | Design Value |
|---|---|
| Superectifier® structure | Reduces stored charge and improves softness of reverse recovery, lowering EMI in uncontrolled rectifier stages |
| Cavity-free glass passivation | Eliminates moisture ingress paths at junction edge, ensuring long-term stability in humid or condensing environments |
| Low leakage (5.0 µA @ 25 °C) | Minimizes standby power loss in offline adapters and maintains regulation accuracy in high-impedance bias networks |
| Solder dip rating: 275 °C / 10 s | Supports wave soldering without parametric shift or delamination, critical for high-volume manufacturing |
| Junction temp max: 175 °C | Enables operation in sealed enclosures or near heat-generating components without thermal shutdown risk |
Applications
| AC-DC Power Supply Input Rectification | DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Full-wave bridge rectification of 115/230 VAC mains input in industrial SMPS. IC Role / Device Role / Timing Role: Uncontrolled rectifier conducting during positive/negative half-cycles; no timing control required. Use Value: 400 V VRRM provides 2× safety margin over 230 VAC RMS; 1.0 V VF limits conduction loss to ≤1 W at 1 A output. | Use Scenario: Freewheeling path for buck converter output inverter stage operating at 30–50 kHz. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when main switch is off; reverse recovery must be fast enough to avoid shoot-through. Use Value: 2.0 µs trr ensures clean turn-off before next switching cycle; 50 A IFSM handles transient inductor current spikes. |
| Inverter DC Bus Clamping | Inductive Load Snubber Protection |
Use Scenario: Clamp diode across motor drive H-bridge DC bus to absorb regenerative energy during braking. IC Role / Device Role / Timing Role: Bidirectional energy sink; conducts only during voltage overshoot events exceeding bus rating. Use Value: 400 V VRRM matches standard 320–400 V DC bus; 175 °C TJ(max) sustains repeated surge duty in enclosed drives. | Use Scenario: Snubber diode across relay coil or solenoid to suppress inductive kickback in PLC I/O modules. IC Role / Device Role / Timing Role: Provides low-impedance discharge path for stored magnetic energy; turns on within nanoseconds of switch opening. Use Value: 1.0 V VF limits clamping voltage to <400 V + 1 V; 5.0 µA IR ensures negligible leakage current in battery-backed circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4004GP-E3/54 | VRRM = 400 V same; IF(AV) = 1.0 A same; trr = 30 µs (slower); VF = 1.1 V (higher) | Not suitable for >10 kHz freewheeling; higher conduction loss reduces efficiency in high-duty-cycle loads | Select 1N4384GPHE3/54 where faster recovery or lower VF is required for thermal or EMI constraints |
| 1N5404G | VRRM = 400 V same; IF(AV) = 3.0 A (higher); DO-201AD package (larger); trr = 2.0 µs same | Requires PCB layout change; better for higher-current designs but over-specified for 1 A applications | Choose 1N4384GPHE3/54 when space-constrained DO-15 footprint and precise 1 A rating are mandatory |
Compared with 1N4004GP-E3/54 and 1N5404G, the 1N4384GPHE3/54 offers optimal balance of speed (2.0 µs), low loss (1.0 V), and compact DO-15 form factor-making it preferred for space-limited, thermally sensitive, or medium-frequency rectification where 1 A rating is exact.

FAQ
Is 1N4384GPHE3/54 suitable for new designs?
No. Vishay explicitly marks the 1N4384GPHE3/54 as "Not for New Designs" per document 88507 (Revision: 05-Oct-2021). It remains available for legacy repair, maintenance, and continuity programs-but designers should evaluate modern alternatives like Vishay's VS-1N4384GHS or onsemi's MUR140 for new projects requiring extended lifecycle support.
What does the 'HE3/54' suffix mean in 1N4384GPHE3/54?
The 'HE3' denotes RoHS-compliant matte tin plating meeting JESD 201 Class 1A whisker resistance; '/54' specifies packaging in 13-inch paper tape and reel with 4000 units per reel. This matches Vishay's ordering code convention shown in the datasheet's "Ordering Information" table.
Can 1N4384GPHE3/54 replace 1N4004 in existing PCBs?
Yes-mechanically and electrically compatible in DO-15 footprint with identical pinout (anode/cathode orientation). However, 1N4384GPHE3/54 offers superior performance: 2.0 µs vs. 30 µs reverse recovery and 1.0 V vs. 1.1 V forward drop. No PCB changes are needed, but verify thermal margin due to tighter VF-driven loss profile.
What is the maximum junction temperature rating for 1N4384GPHE3/54?
The 1N4384GPHE3/54 has a maximum operating junction temperature (TJ) of +175 °C, confirmed in both "Primary Characteristics" and "Maximum Ratings" tables. This allows reliable operation in sealed enclosures or near heat sources where ambient exceeds 100 °C, provided power dissipation stays within RθJA-derived limits.
Does 1N4384GPHE3/54 meet UL 94 V-0 flammability requirements?
Yes. The DO-15 package uses molding compound certified to UL 94 V-0 flammability rating, as stated in the "Mechanical Data" section. This qualifies the 1N4384GPHE3/54 for use in end equipment requiring flame-retardant component housings, including industrial controls and power distribution units.
