onsemi GBPC1501W

Overview

GBPC1501W from Diodes Incorporated is a 15A glass passivated single-phase bridge rectifier with 100V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 7.5A per diode, and 300A non-repetitive surge rating. It features electrically isolated metal base for heatsink mounting, UL recognition (E94661), and RoHS-compliant silver-plated leads. Used in AC/DC power supplies for industrial motor drives requiring high surge tolerance and thermal stability.

For engineers reviewing the GBPC1501W datasheet, GBPC1501W pinout, GBPC1501W application, or GBPC1501W equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (5.0°C/W junction-to-case), case isolation voltage (1500V), and mechanical mounting via #10 screw with 8.0 in-lb torque limit.

Technical Context

This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions to suppress surface leakage and enhance reliability under humid or contaminated conditions. Its internal heatsink-integrated molded plastic case (UL 94V-0) enables direct thermal coupling to external heatsinks without additional insulating hardware.

The GBPC1501W operates across –65°C to +150°C junction temperature range and supports both resistive/inductive loads (full rated current) and capacitive loads (20% current derating). Its 300A IFSM rating accommodates line-start surges in motor control applications without fusing.

FAQ

What is the maximum allowable case temperature for continuous 15A operation?

The GBPC1501W sustains 15A average output current only when case temperature (TC) is maintained at ≤70°C, as defined in its absolute maximum ratings. Exceeding this requires linear derating per Figure 1 in the datasheet-e.g., at TC = 100°C, IO drops to approximately 9.5A. Heatsink design must ensure TC stays within limit under worst-case ambient and airflow conditions.

Can GBPC1501W be used with capacitive input filters without derating?

No-capacitive input loads require 20% current derating per the datasheet. At full 15A rating, the device assumes resistive or inductive loading. For capacitive inputs (e.g., bulk capacitor after rectifier), maximum continuous current is limited to 12A to prevent overheating from high peak currents and increased RMS dissipation.

Is the metal base electrically connected to any terminal?

No-the metal base is fully isolated from all four terminals (AC1, AC2, +, –) with a minimum dielectric strength of 1500V. This isolation is verified per UL E94661 and enables direct mounting to grounded heatsinks without insulating hardware, reducing thermal interface resistance and assembly cost.

Does the "W" suffix affect electrical performance?

No-the "W" suffix denotes wire leads instead of Faston terminals; all electrical specifications (VRRM, IO, IFSM, VFM, etc.) are identical between GBPC1501 and GBPC1501W. The difference is purely mechanical: wire leads allow soldered interconnects and flexible routing, while Faston terminals enable quick panel connections but require crimp tools and compatible receptacles.
