Product details
Overview
GBU410 from Diodes Incorporated is a 4.0A, 1000V standard recovery bridge rectifier in GBU package, featuring 1.0V max forward voltage at 2A, 5µA max reverse leakage at 25°C, 150A non-repetitive surge rating, and UL recognition (E95060). It serves as AC-to-DC front-end rectification in offline power supplies for industrial motor drives, HVAC control boards, and AC-input LED drivers.
For engineers reviewing the GBU410 datasheet, GBU410 pinout, GBU410 application, or GBU410 equivalent, key selection criteria include peak repetitive reverse voltage (1000V), average forward current derating behavior above 100°C case temperature, thermal resistance (2.2°C/W), and through-hole mounting compatibility with #6 screw fastening.
Technical Context
The GBU410 integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated die construction, enabling stable operation up to +150°C junction temperature. Its 150A surge rating supports brief inrush events in transformer-coupled inputs, while 80pF typical junction capacitance minimizes high-frequency noise coupling.
Designed for standard recovery (non-fast/soft) switching, it exhibits no controlled reverse recovery time specification - consistent with legacy rectifier use in 50/60Hz line-frequency applications. The 1500VRMS dielectric strength between case and terminals ensures isolation integrity in grounded-chassis equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage ceiling (e.g., 700V RMS). |
| IF(AV) | 4.0 A @ TC = +100°C - Continuous DC output current capability when mounted on 50×50×1.6mm copper heatsink. |
| VF Max | 1.0 V @ IF = 2.0A - Forward conduction loss per diode pair; determines ~2.0W total dissipation at full load. |
| IR Max | 5 µA @ VR = 1000V, TA = +25°C - Low leakage preserves efficiency in high-impedance hold-up circuits. |
| IFS M | 150 A (8.3ms half-sine) - Withstands transformer inrush and capacitor charging surges without failure. |
| RθJC | 2.2 °C/W - Thermal resistance from junction to case; enables thermal design using measured case temperature. |
| CT | 80 pF @ 1MHz, VR = 4V - Junction capacitance affects EMI filtering requirements and snubber sizing. |
Pinout & Package
Package: GBU molded plastic case (UL 94V-0), through-hole mountable with #6 screw, 3.7g weight, polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |

| 150A surge rating | Eliminates need for external NTC thermistors or inrush limiters in many 4A-rated power supplies. |
Applications
| Industrial Motor Drive Power Supply | HVAC Control Board AC Input Stage |
|---|---|
Use Scenario: Converts 230VAC mains to unregulated DC for logic supply and gate driver rails in variable-frequency drives. IC Role / Device Role / Timing Role: Primary rectifier delivering 4A DC output; operates at line frequency with minimal switching loss. Use Value: 1000V VRRM accommodates 230VAC + 30% tolerance and transient spikes; low IR prevents standby power waste. |
Use Scenario: Rectifies 24VAC transformer output to power microcontroller, relays, and sensor interfaces in climate control units. IC Role / Device Role / Timing Role: Full-wave bridge providing isolated DC rail; mounted directly to metal chassis for thermal conduction. Use Value: 1500VRMS isolation withstands transformer flyback transients; compact GBU footprint saves board space. |
| AC-Input LED Driver for Street Lighting | Offline SMPS Auxiliary Supply |
Use Scenario: Provides bulk DC for constant-current LED driver ICs in outdoor luminaires operating from 120/277VAC lines. IC Role / Device Role / Timing Role: Front-end rectifier feeding bulk capacitor; handles continuous 4A load with 100°C case temperature. Use Value: 2.2°C/W RθJC allows passive heatsinking on aluminum housing; UL recognition simplifies regional certifications. |
Use Scenario: Generates +12V/–12V auxiliary bias rails for PWM controllers and optocouplers in 500W server PSUs. IC Role / Device Role / Timing Role: Dual-polarity rectifier supplying isolated auxiliary windings; operates at low duty cycle but high surge stress. Use Value: 150A IFSM sustains repeated cold-start surges; low VF reduces idle losses during standby mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU10K | Same 1000V VRRM and 4A IF(AV), but 1.1V VF max at 2A; slightly higher forward loss. | Identical pinout and package; validated in automotive HVAC modules per AEC-Q101. | Preferred where AEC-Q101 qualification is mandatory; otherwise GBU410 offers lower VF and UL listing. |
| ON Semiconductor GBPC1010 | 1000V VRRM, 10A IF(AV); larger GBPC package with higher thermal mass and 3.0°C/W RθJC. | Over-specified current rating enables extended lifetime in high-ambient-temperature deployments. | Select when future-proofing for >4A loads or when board layout permits larger footprint and improved thermal margin. |
Compared with GBU410, GBU10K provides automotive-grade reliability at marginally higher conduction loss, while GBPC1010 trades size and cost for significantly higher current headroom and thermal robustness - making each suitable for distinct thermal, qualification, and scalability requirements.

FAQ
What is the maximum allowable case temperature for continuous operation?
The GBU410 supports continuous operation up to +100°C case temperature at its rated 4.0A average forward current. Derating begins beyond this point per Figure 1 in DS21225 - at +125°C case, maximum IF(AV) drops to approximately 2.8A. Mounting on a 50mm × 50mm × 1.6mm copper plate is required to achieve the published thermal resistance of 2.2°C/W.
Is the GBU410 suitable for high-frequency switching applications like PFC or resonant converters?
No - the GBU410 is a standard recovery rectifier with no specified reverse recovery time (trr) and is intended exclusively for 50/60Hz line-frequency rectification. Its 80pF junction capacitance and lack of soft recovery characteristics make it unsuitable for high-frequency (>20kHz) or fast-switching topologies where reverse recovery losses dominate efficiency.
Does the GBU410 meet AEC-Q101 for automotive under-hood use?
The GBU410 is not qualified to AEC-Q101. Diodes offers automotive-grade variants (e.g., GBU10K) with AEC-Q101 certification, PPAP capability, and IATF 16949 manufacturing. GBU410 is rated for –55°C to +150°C operating temperature but lacks the change control, test documentation, and process validation required for automotive qualification.
How does the 1500VRMS dielectric strength impact PCB layout?
The 1500VRMS isolation rating requires minimum creepage and clearance distances between the GBU410's leads and any grounded metal chassis or low-voltage traces. For 230VAC systems, IPC-2221B mandates ≥2.5mm creepage; the GBU410's physical spacing and molded body enable compliance without additional slotting or barriers when mounted per datasheet mechanical guidelines.
