Product details
Overview
1N4004GHB0G from Taiwan Semiconductor is a glass-passivated silicon standard rectifier diode rated for 1 A average forward current and 400 V repetitive peak reverse voltage, with 30 A surge capability and 1.0 V max forward voltage at 1 A; used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the 1N4004GHB0G datasheet, 1N4004GHB0G pinout, 1N4004GHB0G application, or 1N4004GHB0G equivalent, key selection criteria include VRRM=400 V, IFSM=30 A, VF≤1.0 V @ 1 A, TJ(max)=150°C, and DO-41 package compatibility with automated assembly.
Technical Context
This device is a single-die, unidirectional PN-junction rectifier with glass-passivated chip construction for enhanced moisture resistance and long-term reliability under thermal cycling. Its low forward voltage drop and high surge current rating support efficient energy conversion in discontinuous conduction mode (DCM) flyback and buck-derived topologies.
The 1N4004GHB0G operates across –55°C to +150°C junction temperature range and exhibits 5 µA max reverse leakage at 25°C and rated VR, rising to 100 µA at 125°C - critical for standby power loss budgeting in industrial power adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum non-repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage range in AC/DC front-end designs |
| IF(AV) | 1 A - continuous average forward current under specified thermal conditions; sets minimum heatsinking requirement for 100% duty-cycle operation |
| IFSM | 30 A - peak non-repetitive surge current for 8.3 ms half-sine; enables robustness against line transients and inrush in offline SMPS |
| VF | ≤1.0 V @ IF = 1 A, TJ = 25°C - forward voltage drop directly impacts conduction loss and thermal design in rectification stage |
| TJ(max) | +150°C - maximum allowable junction temperature; determines derating curve slope and safe operating area in enclosed environments |
| IR | ≤5 µA @ VR = 400 V, TJ = 25°C - reverse leakage current affecting no-load power consumption and high-impedance bias networks |
| RθJA | 80 °C/W - junction-to-ambient thermal resistance in free-air; used to calculate temperature rise for PCB layout and copper pour sizing |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, glass-passivated, RoHS-compliant, halogen-free molding compound (UL 94V-0), cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of AC source or switch node in freewheeling path; requires adequate trace width for 1 A RMS |
| Cathode | Forward current exit / reverse blocking terminal | Marked by colored band; ties to output rail or positive bus; reverse voltage appears across this terminal during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Prevents moisture ingress and metallization corrosion, enabling >10-year field life in humid industrial environments |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards |
| Pure tin-plated leads | Ensures solderability per J-STD-002 and eliminates lead-free process compatibility issues in reflow assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N4004FS | VRRM=400 V, VF=1.1 V max @ 1 A, RθJA=75 °C/W, same DO-41 package | Slightly higher VF increases conduction loss; tighter thermal resistance allows marginally higher ambient operation | Preferred where thermal headroom is constrained but minor efficiency trade-off is acceptable |
| Vishay 1N4004-E3/54 | VRRM=400 V, VF=1.1 V max @ 1 A, IR=5 µA @ 25°C, AEC-Q101 not claimed | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
Compared with 1N4004FS and 1N4004-E3/54, the 1N4004GHB0G provides verified AEC-Q101 compliance, lower typical VF, and halogen-free construction - making it optimal for automotive subsystems and environmentally regulated industrial designs.

FAQ
What is the peak repetitive reverse voltage rating for the 1N4004GHB0G?
The 1N4004GHB0G has a repetitive peak reverse voltage (VRRM) rating of 400 V. This value defines the maximum reverse-biased voltage the diode can block repeatedly without avalanche breakdown. It is validated per JEDEC test conditions and applies across the full operating temperature range up to TJ = 150°C. Designers must ensure circuit peak reverse stress remains below this limit with appropriate safety margin.
Is the 1N4004GHB0G suitable for automotive applications?
Yes, the 1N4004GHB0G is AEC-Q101 qualified, meaning it has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per JESD22 standards. This qualification confirms its suitability for automotive powertrain, body electronics, and infotainment subsystems where reliability under thermal and mechanical stress is mandatory - a key differentiator from non-qualified 1N4004 variants.
What does the 'H' and 'B0G' suffix indicate in 1N4004GHB0G?
In 1N4004GHB0G, 'H' denotes AEC-Q101 qualification, and 'B0G' specifies packaging: 'B' indicates ammo box packing (3,000 units), '0' is a revision code, and 'G' signifies green (halogen-free) molding compound compliant with IEC 61249-2-21. This full ordering code distinguishes it from tape-and-reel (e.g., 1N4004GHA0G) and non-automotive versions (e.g., 1N4004G).
How does the forward voltage of the 1N4004GHB0G affect power loss in a 1 A application?
At 1 A forward current and 25°C junction temperature, the 1N4004GHB0G exhibits a maximum forward voltage (VF) of 1.0 V. This results in 1.0 W of conduction loss (P = VF × IF). In continuous operation, that loss must be dissipated via PCB copper or ambient air - requiring thermal design based on its 80 °C/W RθJA. Lower VF directly improves system efficiency and reduces thermal management complexity.
Can the 1N4004GHB0G replace a 1N4007 in a 600 V circuit?
No, the 1N4004GHB0G is rated for 400 V VRRM and must not be substituted for a 1N4007 (1000 V) in circuits where reverse voltage exceeds 400 V. Doing so risks catastrophic failure due to reverse breakdown. The 1N4004GHB0G is part of a voltage-scaled family - always match the 'x' digit (4 → 400 V) to the circuit's peak reverse stress, with ≥20% design margin recommended.
