Product details
Overview
GBU1010 from Diodes Incorporated is a 10A, 1000V standard recovery bridge rectifier in GBU package, featuring 1.0V max forward voltage at 5A, 5µA max reverse leakage at 25°C, and 220A non-repetitive surge rating. It delivers high dielectric strength (1500VRMS), low capacitance (60pF), and is optimized for AC/DC power supplies in industrial motor drives and HVAC control systems.
For engineers reviewing the GBU1010 datasheet, GBU1010 pinout, GBU1010 application, or GBU1010 equivalent, key selection criteria include peak reverse voltage (1000V), average forward current (10A), thermal resistance (2.2°C/W), surge capability (220A), and through-hole mounting compatibility with #6 screw.
Technical Context
This single-phase, full-wave bridge rectifier uses glass-passivated silicon die to achieve stable conduction under continuous 10A load at 100°C case temperature and withstand transient surges up to 220A (8.3ms half-sine). Its 1500VRMS isolation supports safe operation in mains-connected equipment.
The device exhibits 60pF junction capacitance at 1MHz/4V reverse bias and 2.2°C/W typical junction-to-case thermal resistance when mounted on a 100mm × 100mm × 1.6mm copper heatsink - enabling predictable thermal design in compact power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input range (e.g., 707V RMS). |
| IF(AV) | 10 A - Average forward current at TC = +100°C; sets continuous DC output capability with proper heatsinking. |
| VF Max | 1.0 V @ 5A - Forward voltage drop per diode pair; determines conduction loss (≈5W at 5A full-wave). |
| IR Max | 5 µA @ 25°C - Reverse leakage current; ensures minimal standby power loss in off-state. |
| IFSM | 220 A - Non-repetitive surge rating (8.3ms); supports inrush current handling during cold start. |
| RθJC | 2.2 °C/W - Junction-to-case thermal resistance; enables thermal modeling for PCB copper heatsink design. |
| CT | 60 pF - Junction capacitance at 1MHz/4V; impacts EMI filtering and high-frequency switching behavior. |
Pinout & Package
Package: GBU - 4-pin through-hole plastic package (UL 94V-0), 22.05mm × 17.75mm × 10.1mm, matte tin-plated terminals, mountable with #6 screw (5.0 in-lb max torque).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC terminal 1 | One of two AC input pins; connected internally to cathode of D1 and anode of D2 in bridge topology. |
| AC2 | Input AC terminal 2 | Second AC input pin; connected internally to cathode of D3 and anode of D4 - forms full-wave input path. |
| + (Anode) | Positive DC output | Common cathode node of D1 and D3; delivers rectified positive output voltage. |
| – (Cathode) | Negative DC output | Common anode node of D2 and D4; serves as return path for DC load current. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | Same 1000V VRRM, 10A IF(AV), but VF = 1.1V max @ 5A; slightly higher conduction loss. | Identical mechanical footprint and pinout; validated in legacy industrial designs. | Preferred where second-source qualification is required and 0.1V VF increase is acceptable. |
| KBU1010 (Shindengen) | 1000V VRRM, 10A IF(AV), VF = 1.05V max @ 5A; 200A IFSM (vs. 220A). | Same GBU package; lower surge rating may require derating in high-inrush applications. | Consider for cost-sensitive lighting or consumer-grade power supplies with moderate surge exposure. |
Compared with GBU10K and KBU1010, the GBU1010 offers the lowest forward voltage (1.0V) and highest surge rating (220A), making it optimal for demanding industrial rectification where thermal efficiency and transient robustness are critical.

FAQ
What is the maximum operating temperature for GBU1010?
The GBU1010 has a junction temperature range of –55°C to +150°C and a storage temperature range of –55°C to +150°C. Its 10A average forward current rating is specified at TC = +100°C, meaning the case must be maintained at or below this temperature under full load using appropriate heatsinking.
Can GBU1010 be used in capacitive-input filter applications?
No - the datasheet explicitly states that for capacitive loads, the average forward current must be derated by 20%. At 10A rated current, this reduces usable output to 8A. Use in such configurations requires verifying thermal performance with actual ripple current and capacitor ESR.
Is GBU1010 suitable for automotive applications?
GBU1010 is not AEC-Q101 qualified. While Diodes offers automotive-grade variants in the GBU family, this specific part is intended for industrial and commercial use. For automotive designs, contact Diodes directly for PPAP-capable, IATF 16949-manufactured alternatives.
How is polarity marked on the GBU1010 package?
The GBU1010 body is marked with a white band indicating the positive (+) DC output terminal. The four terminals are arranged with AC1 and AC2 on one side, and + and – on the opposite side - consistent with standard GBU bridge orientation shown in Diodes' package outline DS30052.
