onsemi GBPC1501

Overview

GBPC1501 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, and 300A non-repetitive surge rating - designed for AC/DC conversion in industrial power supplies, motor controls, and UPS systems.

For engineers reviewing the GBPC1501 datasheet, GBPC1501 pinout, GBPC1501 application, or GBPC1501 equivalent, key selection criteria include thermal resistance (5.0°C/W), case-to-terminal isolation (1500V), UL recognition (E94661), and through-hole mounting compatibility with #10 screw.

Technical Context

This bridge rectifier integrates four silicon diodes in a single molded plastic package with internally mounted heatsink, enabling full-wave AC-to-DC conversion without external discrete assembly. Its glass passivated die construction ensures low reverse leakage (5.0μA at 25°C) and stable operation up to 150°C junction temperature.

The device supports resistive/inductive loads at 60Hz and requires 20% current derating for capacitive loads. Thermal performance relies on mechanical mounting to an external heatsink - case-to-junction thermal resistance is specified at 5.0°C/W when mounted on a 220×220×50mm aluminum plate.

FAQ

What is the maximum operating temperature for GBPC1501?

The GBPC1501 has a junction temperature range of −65°C to +150°C and a storage temperature limit of the same. Continuous operation at 150°C requires strict thermal management - the 15A rating is only valid at TC = 70°C, and derating curves show usable current drops to ~9A at TC = 100°C.

Can GBPC1501 be used with capacitive loads?

Yes, but with 20% current derating applied to the 15A average rating per datasheet guidance. Capacitive input filters increase peak diode current and reduce conduction angle, raising thermal stress and ripple current demands beyond resistive/inductive load conditions.

Does GBPC1501 require a heatsink?

Yes - the 5.0°C/W thermal resistance is specified only when mounted to an external heatsink (e.g., 220×220×50mm Al plate). Without heatsinking, the device cannot sustain 15A continuously; case temperature will exceed safe limits within seconds under full load.

What does the "W" suffix mean in GBPC1501W?

The "W" suffix denotes wire-lead termination instead of Faston terminals. GBPC1501W uses tinned copper leads for PCB through-hole soldering, while GBPC1501 uses insulated Faston connectors for chassis or terminal-block mounting - same electrical specs, different mechanical interface.
