Product details
Overview
GBU1007-K from Taiwan Semiconductor is a 10A, 1000V rated standard bridge rectifier in GBU package, configured as a quad diode arrangement for full-wave AC-to-DC conversion. It delivers 200A surge current capability, operates up to 150°C junction temperature, and is UL Recognized (E-326243) for use in high-reliability power supplies.
For engineers reviewing the GBU1007-K datasheet, GBU1007-K pinout, GBU1007-K application, or GBU1007-K equivalent, key selection factors include its 1000V VRRM, 1.10V max forward voltage at 10A/25°C, 1.2°C/W junction-to-case thermal resistance, and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
The GBU1007-K implements a monolithic quad-diode bridge configuration with common-cathode and common-anode terminals, enabling single-package full-wave rectification without external interconnects. Its 1000V repetitive peak reverse voltage rating and 700V RMS reverse voltage support operation in universal-input SMPS front-ends.
Thermal performance is defined by RθJC = 1.2°C/W and RθJL = 1.7°C/W when mounted on an aluminum heat sink (4" × 6" × 0.25"), allowing sustained 10A average forward current under controlled thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum repetitive reverse voltage per diode; defines safe AC input voltage ceiling (e.g., 707VRMS sine wave) |
| IF | 10 A - continuous average forward current; specifies steady-state DC output capability at TC ≤ 75°C |
| IFSM | 200 A - non-repetitive surge current (8.3 ms half-sine); supports inrush tolerance in offline power supplies |
| VF (max) | 1.10 V @ 10A, 25°C - forward voltage drop limit; determines conduction loss and thermal load at full rated current |
| TJ max | +150°C - maximum junction temperature; enables operation in high-ambient industrial environments |
| RθJC | 1.2 °C/W - junction-to-case thermal resistance; quantifies heat transfer efficiency to heatsink interface |
| IR (max) | 500 μA @ 125°C - reverse leakage per diode; impacts standby power and high-temperature reliability |

IC Role / Device Role / Timing Role: Single-package full-wave solution eliminating discrete diode layout complexity and trace inductance. Use Value: GBU package footprint and 1.2°C/W RθJC allow direct mounting to metal chassis or small heatsinks without thermal vias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1006-K | 800V VRRM, 560V VR(RMS) - 20% lower reverse voltage rating than GBU1007-K | Suitable only for 230VAC-only systems; insufficient margin for universal-input or surge-prone environments | Select when cost optimization is prioritized and input voltage is strictly limited to ≤230VAC. |
| GBU10K | 1000V VRRM, same package, but 10A rating with 170A IFSM (vs. 200A) and higher VF (1.2V max) | Lower surge tolerance and higher conduction loss; may require thermal redesign in high-inrush applications | Acceptable for legacy designs where GBU1007-K is unavailable, but verify IFSM and thermal margins. |
Compared with GBU1006-K and GBU10K, the GBU1007-K offers superior surge immunity (200A vs. 170A/150A), tighter forward voltage control (1.10V max), and highest reverse voltage margin-making it optimal for universal-input, high-reliability, and thermally constrained power supply designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the GBU1007-K?
The GBU1007-K has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, as confirmed in the Absolute Maximum Ratings table. This rating applies per diode within the bridge and defines the device's ability to block reverse voltage during AC input cycles. The GBU1007-K is the highest-voltage variant in the GBU1005-K through GBU1007-K family, distinguishing it from the 600V GBU1005-K and 800V GBU1006-K.
Does the GBU1007-K meet RoHS and halogen-free requirements?
Yes, the GBU1007-K is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official documentation. These compliance attributes are verified for the GBU1007-K part number and apply to its molded plastic body and matte tin-plated leads, supporting environmentally regulated electronics manufacturing.
What is the forward voltage (VF) specification for the GBU1007-K at full rated current?
The GBU1007-K has a maximum forward voltage (VF) of 1.10 V at 10 A and 25°C, per the Electrical Specifications table. At elevated temperature (125°C), VF drops to 0.88 V (typical), reflecting the negative temperature coefficient of silicon diodes. This VF value directly determines conduction losses in the GBU1007-K during continuous operation.
Is the GBU1007-K UL Recognized, and what is its file number?
Yes, the GBU1007-K is UL Recognized under File # E-326243, as documented in the FEATURES list and confirmed across all revision pages of the official datasheet. This recognition covers the GBU1007-K specifically and validates its safety construction for use in end equipment subject to UL/CSA standards.
What thermal resistance values are specified for the GBU1007-K?
The GBU1007-K specifies RθJC = 1.2°C/W (junction-to-case), RθJL = 1.7°C/W (junction-to-lead), and RθJA = 7.6°C/W (junction-to-ambient, measured on a 4" × 6" × 0.25" Al-plate). These values are measured under defined test conditions and apply directly to the GBU1007-K in its standard GBU package configuration.
