onsemi GBPC1510W

Overview

GBPC1510W from Diodes Incorporated is a 15A, 1000V glass passivated single-phase bridge rectifier in GBPC-W package with wire leads, designed for AC-to-DC conversion in industrial power supplies and motor controls. It delivers 1.1V forward voltage at 7.5A per diode, supports 300A non-repetitive surge current, and features 1500V case-to-terminal isolation for enhanced safety in high-voltage systems.

For engineers reviewing the GBPC1510W datasheet, GBPC1510W pinout, GBPC1510W application, or GBPC1510W equivalent, key selection criteria include peak reverse voltage rating (1000V), thermal resistance (5.0°C/W), surge capability (300A), isolation voltage (1500V), and mounting compatibility with #10 screw heatsink interfaces.

Technical Context

This bridge rectifier integrates four silicon diodes in a single molded plastic package with internally mounted heatsink, enabling efficient heat transfer to external metal heatsinks. Its glass passivated die construction ensures low reverse leakage (5.0μA @ 25°C) and stable performance across -65°C to +150°C operating range.

The device is rated for 15A average output current at TC = 70°C with derating required for capacitive loads (−20% current). Thermal resistance junction-to-case is 5.0°C/W when mounted on a heatsink, supporting reliable operation under sustained load conditions in industrial AC/DC front-ends.

FAQ

What is the maximum case temperature for continuous operation of GBPC1510W?

The device is rated for continuous operation up to +150°C junction temperature. At TC = 70°C, it delivers full 15A output current. Derating follows Fig. 1 in the datasheet: output current reduces linearly to zero at ~150°C case temperature. Proper heatsinking is mandatory to maintain TC ≤ 70°C under full load.

Can GBPC1510W be used with capacitive loads without derating?

No. The datasheet explicitly requires 20% current derating for capacitive loads due to higher peak currents during capacitor charging. For example, maximum allowable IO drops from 15A to 12A when feeding bulk electrolytic capacitors directly after rectification without pre-charge or inrush limiting.

Does GBPC1510W require a heatsink for 10A continuous operation?

Yes. Even at 10A, power dissipation exceeds 11W (10A × 1.1V × 2 diodes conducting). With RθJC = 5.0°C/W, junction temperature rise alone would exceed 55°C above case temperature. A heatsink is essential to limit TC and TJ within rated limits - especially given ambient temperatures >40°C in industrial enclosures.

How does the "W" suffix affect mechanical mounting and thermal performance?

"W" denotes wire leads instead of Faston terminals, enabling direct soldering or screw-terminal connection. Mechanically, it retains the same central mounting hole (5.08–5.59 mm) for #10 screw attachment to heatsinks. Thermal performance is identical to GBPC1510 because both share the same GBPC-W case construction, internal heatsink, and RθJC = 5.0°C/W specification.
