Product details
Overview
GBU1001 from Diodes Incorporated is a 10A standard recovery bridge rectifier in GBU package, rated for 100V repetitive peak reverse voltage (VRRM), 1.0V max forward voltage at 5A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and 220A non-repetitive surge capability - used in AC/DC power supplies for industrial control panels requiring robust line-input rectification.
For engineers reviewing the GBU1001 datasheet, GBU1001 pinout, GBU1001 application, or GBU1001 equivalent, key selection criteria include VRRM margin for 120VAC input with transients, thermal resistance (2.2°C/W junction-to-case), IFSM rating for inrush handling, and UL recognition (E95060) for safety-compliant designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a common cathode/anode configuration to convert AC input to pulsating DC. Its standard recovery time (~2.5µs typical) balances switching loss and EMI in line-frequency applications, and it operates across -55°C to +150°C junction temperature range.
The device uses matte tin-plated through-hole terminals compatible with MIL-STD-202 soldering, mounted via #6 screw with ≤5.0 in-lb torque. Its plastic package meets UL 94V-0 flammability rating and supports PCB-level mounting without heatsink for ≤7A continuous operation at TC = 100°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands 100V repetitive reverse voltage, suitable for 120VAC mains with 2× safety margin against transients. |
| IF(AV) | 10 A - Average forward current rating at TC = 100°C, derated to ~7A at ambient 50°C on standard PCB. |
| VF Max | 1.0 V @ 5A - Low conduction loss enables <5W total dissipation at full-rated average current. |
| IR Max | 5 µA @ 25°C - Minimal reverse leakage preserves efficiency in high-impedance hold-up circuits. |
| IFSM | 220 A - Handles 8.3ms half-sine surge, sufficient for cold-start inrush of transformer-coupled supplies. |
| RθJC | 2.2 °C/W - Enables thermal design with external heatsink for sustained 10A operation. |
| CT | 60 pF @ 4V, 1MHz - Low junction capacitance minimizes high-frequency noise coupling in EMI-sensitive systems. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC Terminal 1 | One AC input node; connects to live/phase side of transformer secondary or mains input. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1002 (Diodes Inc.) | 200V VRRM, identical IF(AV), VF, and package; same thermal specs and surge rating. | Higher reverse voltage margin for 230VAC or 120VAC with elevated transient immunity requirements. | Select when designing for dual-voltage (120/230VAC) global power inputs or where >100V transients are expected. |
| KBU1001 (ON Semiconductor) | Same 100V VRRM and 10A rating; VF = 1.1V max @ 5A; RθJC = 2.5°C/W; UL recognized (E151272). | Slightly higher conduction loss and thermal resistance; identical pinout and footprint compatibility. | Acceptable drop-in replacement where 0.1V VF increase and +0.3°C/W thermal penalty are acceptable in thermally relaxed layouts. |
Compared with GBU1001, GBU1002 offers higher reverse voltage headroom without sacrificing current or thermal performance, while KBU1001 provides second-source availability with minor trade-offs in efficiency and thermal management margin.

FAQ
Is GBU1001 suitable for 230VAC input applications?
No - GBU1001 has a 100V VRRM rating, making it unsuitable for direct 230VAC rectification. For 230VAC systems, use GBU1004 (400V) or GBU1006 (600V) to maintain ≥2× safety margin against peak line voltage (325V) and transients. Derating below 100V VRRM risks premature breakdown during surge events.
What is the recommended minimum copper area for heatsinking GBU1001 at 10A?
Diodes specifies 100mm × 100mm × 1.6mm copper plate for the 2.2°C/W RθJC value. For PCB-only cooling (no external heatsink), a minimum 2500 mm² (e.g., 50mm × 50mm) 2-oz copper pour with thermal vias to inner layers is required to sustain 7A at TA = 50°C. Below that, derate linearly per Figure 1.
Does GBU1001 require snubber circuits in standard line-frequency operation?
Snubbers are not required for resistive or inductive loads at 50/60Hz. However, they are recommended when driving highly capacitive inputs (e.g., large bulk capacitors without pre-charge) to limit di/dt-induced voltage overshoot and reduce EMI. Standard recovery behavior inherently limits ringing compared to fast-recovery types.
Can GBU1001 be used in automotive under-hood applications?
While GBU1001 operates from -55°C to +150°C, it is not AEC-Q101 qualified. Diodes explicitly states that automotive-grade versions require PPAP-capable, IATF 16949-manufactured parts - GBU1001 is intended for industrial/commercial use only. For automotive, specify AEC-Q101-certified alternatives like DB101S or equivalent.
