Product details
Overview
GBU2507 from Taiwan Semiconductor is a 25A, 1000V standard bridge rectifier in GBU package with quad configuration, low forward voltage (1.08–1.20 V at 25 A, 25°C), 300 A surge capability, and 150°C maximum junction temperature - used in high-reliability AC/DC front-ends for industrial SMPS.
For engineers reviewing the GBU2507 datasheet, GBU2507 pinout, GBU2507 application, or GBU2507 equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJC = 1.0°C/W), forward voltage consistency across temperature, and UL recognition (E-326243) for safety-critical power conversion designs.
Technical Context
The GBU2507 integrates four silicon diodes in a single-phase full-wave bridge configuration, rated for repetitive peak reverse voltage of 1000 V and RMS reverse voltage of 700 V. Its thermal design supports mounting on a 4″ × 6″ × 0.25″ aluminum heatsink, delivering RθJA = 6.7°C/W and RθJC = 1.0°C/W under specified conditions.
Electrical behavior is characterized by temperature-dependent forward voltage (1.03–1.15 V at 25 A, 125°C) and reverse leakage (≤500 µA at 125°C, rated VR). Junction capacitance per diode is 100 pF at 1 MHz and 4 V reverse bias, supporting stable switching performance in high-frequency rectification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2510 (Taiwan Semiconductor) | 1000 V VRRM, same package and IF, but higher IFSM = 350 A and lower VF (1.05 V typ. @ 25 A) | Better surge margin and efficiency in high-inrush systems; identical footprint | Select GBU2510 when designing for >300 A surge immunity or tighter thermal budgets |
| GBU25J (ON Semiconductor) | 1000 V VRRM, 25 A IF, but RθJC = 1.5°C/W and no UL file number listed | Lacks UL recognition; requires additional safety validation; slightly higher thermal resistance | Choose GBU25J only if UL certification is not required and heatsink design accommodates +0.5°C/W penalty |
Compared with GBU2507, GBU2510 offers superior surge handling and efficiency at identical voltage rating and footprint, while GBU25J trades UL compliance and thermal performance for alternate supply-chain availability - making GBU2507 the balanced choice for certified, thermally constrained industrial designs.

FAQ
What is the peak repetitive reverse voltage rating of the GBU2507?
The GBU2507 has a peak repetitive reverse voltage (VRRM) rating of 1000 V, verified per Taiwan Semiconductor's datasheet revision E2205. This rating ensures safe operation under worst-case AC line transients in 700 VRMS systems. The GBU2507 must not be operated beyond this voltage to prevent avalanche breakdown or catastrophic failure.
Does the GBU2507 have UL recognition, and what is the file number?
Yes, the GBU2507 is UL Recognized under file number E-326243, as confirmed in the official Taiwan Semiconductor datasheet. This certification applies to the entire GBU2504–GBU2507 family and validates compliance with UL 60950-1 and UL 62368-1 for end-equipment safety approvals.
What is the maximum junction temperature and thermal resistance of the GBU2507?
The GBU2507 has a maximum junction temperature (TJMAX) of +150°C and a junction-to-case thermal resistance (RθJC) of 1.0°C/W when mounted per specification on a 4″ × 6″ × 0.25″ aluminum heatsink. These values are measured under standardized test conditions and define the upper thermal operating limits for reliable long-term use.
How does the forward voltage of the GBU2507 vary with temperature and current?
Per datasheet E2205, the GBU2507 exhibits forward voltage (VF) of 1.08–1.20 V at 25 A and 25°C, decreasing to 1.03–1.15 V at 25 A and 125°C. This negative temperature coefficient improves thermal stability in parallel or high-ambient deployments, reducing risk of thermal runaway.
Is the GBU2507 halogen-free and RoHS compliant?
Yes, the GBU2507 is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the Taiwan Semiconductor product documentation. The molding compound contains no brominated or chlorinated flame retardants, satisfying environmental compliance requirements for export and green manufacturing programs.
