Product details
Overview
GBU1002 D2G from Taiwan Semiconductor is a 10A, 100V rated standard bridge rectifier in GBU package, featuring 220A surge current capability, 1.1V max forward voltage at 10A/25°C, and <5µA reverse leakage at 25°C - used in AC/DC front-end stages of compact SMPS and LED drivers.
For engineers reviewing the GBU1002 D2G datasheet, GBU1002 D2G pinout, GBU1002 D2G application, or GBU1002 D2G equivalent, key selection criteria include VRRM=100V, IF=10A, RθJC=2°C/W, TJ(max)=150°C, and UL Recognized (E-326243) compliance for industrial power conversion designs.
Technical Context
The GBU1002 D2G integrates four silicon diodes in a single-phase full-wave bridge configuration with quad-terminal layout (AC1, AC2, +, –), optimized for high-density PCB mounting. Its 1500VRMS dielectric strength and matte tin-plated leads meet J-STD-002 solderability requirements.
Thermally, it delivers RθJA=21°C/W (free-air) and RθJC=2°C/W, enabling reliable operation up to 150°C junction temperature. Reverse recovery is not specified; device operates as a standard (non-fast) rectifier with typical CJ=211pF per diode at 1MHz/4V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage per diode; defines safe AC input peak handling (≤70.7V RMS) |
| IF | 10 A - average forward current rating; determines continuous DC output capability in bridge topology |
| IFSM | 220 A - non-repetitive surge current (8.3ms half-sine); supports inrush current during cold start |
| VF (max) | 1.1 V @ 10A/25°C - forward drop impacts conduction loss and thermal design in 12V–48V output supplies |
| IR (max) | 5 µA @ 25°C - low leakage ensures minimal standby power loss in offline adapters |
| RθJC | 2 °C/W - enables direct heatsinking to chassis or metal-core PCB for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1002 from ON Semiconductor | VRRM=100V, IF=10A, same GBU package; VF=1.1V max but IR=10µA max (vs. 5µA for GBU1002 D2G) | Identical functional role; slightly higher leakage may impact ultra-low-standby designs | Select when sourcing diversification is required and 5µA leakage margin is not critical |
| KBU10B from Diodes Inc. | Same 10A/100V rating, KBU package (larger: 20.5×15.5mm vs. GBU's 19.5×15.5mm); VF=1.05V max, IR=5µA max | Requires PCB layout change due to different lead pitch and body size; better thermal RθJA=18°C/W | Choose for improved thermal performance where board space permits package swap |
Compared with GBU1002 D2G, the ON Semiconductor GBU1002 offers equivalent electrical specs but looser IR spec, while the Diodes Inc. KBU10B improves thermal resistance at the cost of mechanical compatibility - both require validation against layout and leakage-sensitive use cases.

FAQ
What is the maximum junction temperature rating for GBU1002 D2G?
The GBU1002 D2G has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of −55°C to +150°C. This rating allows operation in high-ambient environments such as enclosed LED drivers or industrial enclosures. Derating curves in the datasheet show usable current decreases above 75°C case temperature. Thermal design must respect RθJC = 2°C/W and RθJA = 21°C/W limits to avoid exceeding TJ(max) under load.
Does GBU1002 D2G have AEC-Q101 qualification?
No, GBU1002 D2G is not AEC-Q101 qualified. The AEC-Q101 variant is designated as GBU1002H per Taiwan Semiconductor's ordering code table. GBU1002 D2G is intended for industrial and commercial applications. For automotive underhood or infotainment systems requiring stress-tested reliability, the GBU1002H version must be selected and verified against full AEC-Q101 test conditions.
What is the pin configuration and polarity marking for GBU1002 D2G?
The GBU1002 D2G uses a standard GBU quad-terminal configuration: AC1 and AC2 are the two AC input pins, "+" is the positive DC output, and "–" is the negative DC output/common. Polarity is marked on the device body per Taiwan Semiconductor's marking diagram - "+" symbol adjacent to the positive terminal, with cathode band absent (bridge-integrated). Pin 1 (AC1) is typically located at the leftmost lead when viewing the marking side.
How does the forward voltage of GBU1002 D2G affect power loss in a 10A application?
At 10A and 25°C, GBU1002 D2G exhibits a maximum forward voltage (VF) of 1.1V per diode, resulting in ~2.2V total drop across the bridge. This yields conduction loss of 22W (10A × 2.2V), requiring thermal management via heatsinking or airflow. Loss increases with temperature and current - at 125°C, VF rises, further elevating losses. Designers should use the derating curve and RθJC=2°C/W to size thermal interface accordingly.
Is GBU1002 D2G compliant with RoHS and halogen-free standards?
Yes, GBU1002 D2G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These attributes are confirmed in Taiwan Semiconductor's official documentation (Version M2103) and support compliance for CE-marked, WEEE-regulated, and eco-label-certified products targeting EU, Japan, and South Korea markets.
