GBPC3504W

Overview

The onsemi GBPC3504W is a single-phase bridge rectifier from the GBPC35W series, rated for a maximum repetitive peak reverse voltage (Vrrm) of 400 V and an average forward rectified current (If) of 35 A. It features a peak non-repetitive forward surge current (Ifsm) capability of 300 A and a maximum forward voltage drop (Vf) of 1.1 V. The device operates within a junction temperature range of -55°C to +150°C and exhibits a low reverse leakage current (Ir) of 500 μA. Housed in a standard 4-pin GBPC through-hole package with dimensions of 29 mm length and 11.23 mm height, it provides robust performance for general-purpose power supply applications.

Feature Summary

• High thermal stability with a maximum operating junction temperature of 150°C
• Robust surge handling capability with 300 A peak non-repetitive forward current rating
• Low forward voltage drop of 1.1 V for improved efficiency
• Compact GBPC-W through-hole package design

Applications

• General-purpose AC-DC power supplies
• Battery chargers
• Industrial control systems

Procurement Notes

Verify the manufacturer origin carefully, as the GBPC3504W designation is widely used by multiple vendors including Taiwan Semiconductor and Panjit. Confirm that the specific unit received matches the onsemi datasheet specifications, particularly the Ifsm rating of 300 A versus the 400 A found in other series variants. Ensure the package marking aligns with onsemi's identification standards to avoid counterfeit or mislabeled components.

Selection Notes

Select this component when a 400 V blocking voltage and 35 A continuous current are required in a compact through-hole format. Note that the GBPC3504W variant specifies a 300 A surge rating, which differs from the standard GBPC3504 (400 A surge). Verify thermal management requirements based on the 1.1 V forward voltage drop at full load conditions.

Part Context

The GBPC3504W belongs to the GBPC35W series, distinguished by its specific surge current rating compared to the broader GBPC35 family. While sharing the same physical GBPC footprint and basic electrical ratings like 35 A current and 400 V voltage, the 'W' suffix often denotes specific manufacturing lines or slight parameter variations such as the reduced 300 A surge capability documented for this specific part number.

Replacement Considerations

Direct substitutes include GBPC3504 from onsemi, though verification of the 400 A vs 300 A surge rating is critical. Other manufacturers offer pin-compatible alternatives such as KBPC3504WP from Diotec or GBPC3504W from Taiwan Semiconductor, but exact electrical matching must be confirmed against the original datasheet.
