Product details
Overview
GBPC3504 from Taiwan Semiconductor is a 35A, 400V rated standard single-phase bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, and integrally molded heatsink for low thermal resistance (1.5°C/W). It delivers ≤1.1V forward voltage at 17.5A and <5µA reverse leakage at rated voltage, used in AC-DC converters and switching mode power supplies.
For engineers reviewing the GBPC3504 datasheet, GBPC3504 pinout, GBPC3504 application, or GBPC3504 equivalent, key selection criteria include peak repetitive reverse voltage (400V), average forward current (35A), surge capability (400A @ 8.3ms), thermal resistance (1.5°C/W), and UL recognition (E-326243).
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with common cathode and anode terminals. Its glass-passivated junction ensures stable reverse blocking and low IR drift over temperature.
The GBPC3504 uses a thermally optimized GBPC package with integrally molded heatsink, enabling direct mounting to external heat sinks and supporting continuous operation up to 150°C junction temperature under proper thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive peak reverse voltage per diode; defines safe AC input voltage handling (e.g., 280V RMS) |
| IF(AV) | 35 A - Average forward current rating; determines continuous DC output capability in rectified circuits |
| IFSM | 400 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush tolerance during power-up |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables efficient heat transfer to heatsink for thermal stability |
| VF | ≤1.1 V - Forward voltage per diode at 17.5A/25°C; directly impacts conduction loss and efficiency |
| IR | ≤5 µA - Reverse leakage current at rated VR and 25°C; critical for low-power standby and high-impedance bias networks |
Pinout & Package
GBPC3504 is housed in the standard GBPC package - a 4-terminal, through-hole, integrally molded heatsink package with cathode and anode terminals on opposite sides. The case serves as the thermal path and mechanical mounting interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal | One of two alternating current input connections; tied internally to anode of D1 and cathode of D2 |
| AC2 | AC Input Terminal | Second AC input connection; tied internally to anode of D3 and cathode of D4 |
| + (Cathode) | DC Output Positive | Common cathode node of D1 and D3; delivers rectified positive DC output |
| – (Anode) | DC Output Negative | Common anode node of D2 and D4; serves as rectified negative/return path |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enhances long-term reliability and reduces IR drift across temperature and humidity stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC3504 | Identical electrical specs (35A, 400V, 1.5°C/W), same GBPC package, but manufactured by Vishay under second-source agreement | No functional or layout difference; validated in same reference designs and production builds | Drop-in replacement where dual-sourcing is required for supply chain resilience |
| ON Semiconductor GBU35J | Same current (35A) and voltage (600V) ratings, but GBU package (lower thermal resistance: 1.2°C/W); slightly smaller footprint | Higher VRRM allows use in 380VAC systems; requires PCB pad revision due to different terminal spacing and heatsink geometry | Preferred when higher reverse margin or improved thermal performance is needed, and board redesign is feasible |
Compared with Vishay GBPC3504 and ON Semi GBU35J, the Taiwan Semiconductor GBPC3504 offers identical performance in UL-recognized GBPC packaging, while the GBU35J provides higher voltage margin and better thermal resistance at the cost of mechanical incompatibility.

FAQ
What is the maximum junction temperature for GBPC3504?
The GBPC3504 has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version M2211). This allows reliable operation in high-ambient environments when thermal resistance (RθJC = 1.5°C/W) is properly managed via heatsinking. Derating curves confirm usable current capacity down to 0A at 150°C case temperature.
Does GBPC3504 meet UL safety standards?
Yes, GBPC3504 is UL Recognized under File #E-326243, as stated in the official Taiwan Semiconductor datasheet. This certification covers flammability (UL 94V-0 molding compound), terminal construction, and electrical isolation integrity - essential for end-product safety approvals in commercial and industrial power supplies.
What is the forward voltage drop of GBPC3504 at rated current?
The GBPC3504 exhibits a maximum forward voltage (VF) of 1.1 V per diode at IF = 17.5 A and TJ = 25°C, per electrical specifications in the Taiwan Semiconductor datasheet. This value reflects worst-case conduction loss under typical operating conditions and is critical for calculating total rectifier power dissipation (≈2.2 V × load current).
Is GBPC3504 RoHS compliant and lead-free solder compatible?
Yes, GBPC3504 is RoHS compliant and features matte tin-plated leads qualified per J-STD-002 for solderability. It also passes JESD201 Class 1A whisker testing, ensuring reliability in lead-free reflow processes. These qualifications are explicitly documented in the Mechanical Data section of the Taiwan Semiconductor datasheet (Version M2211).
What does the "04" suffix indicate in GBPC3504?
The "04" in GBPC3504 denotes the peak repetitive reverse voltage rating of 400 V, per Taiwan Semiconductor's ordering code convention: "005" = 50V, "01" = 100V, "02" = 200V, "04" = 400V, etc. The "35" indicates 35A average forward current, confirming this is the 35A/400V variant of the GBPC family.
