Product details
Overview
GBPC1508 from Diodes Incorporated is a 15A glass passivated single-phase bridge rectifier with 800V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 7.5A per diode, and 300A non-repetitive surge rating - used in AC/DC power supplies for industrial motor drives and HVAC control systems.
For engineers reviewing the GBPC1508 datasheet, GBPC1508 pinout, GBPC1508 application, or GBPC1508 equivalent, key selection criteria include thermal resistance (5.0°C/W junction-to-case), case isolation voltage (1500V), and UL recognition (E94661) for safety-critical power conversion designs.
Technical Context
This bridge rectifier integrates four silicon diodes in a single molded plastic package with internally mounted heatsink, configured as a full-wave single-phase bridge. Its glass passivated die construction ensures low reverse leakage (5.0μA @ 25°C) and stable operation up to 150°C junction temperature.
Designed for through-hole mounting with #10 screw, it delivers 15A average output current at TC = 70°C when mounted on a 220 × 220 × 50 mm aluminum heatsink. The device supports resistive/inductive loads without derating but requires 20% current reduction for capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum peak reverse voltage the bridge withstands without breakdown |
| IO @ TC=70°C | 15 A - Continuous average DC output current under specified thermal conditions |
| IFSM | 300 A - Single half-sine surge capability (8.3ms), critical for inrush protection |
| VFM @ IF=7.5A | 1.1 V - Forward voltage per diode element, directly impacts conduction loss |
| RθJC | 5.0 °C/W - Thermal resistance from junction to case, determines heatsink sizing |
| IR @ 25°C | 5.0 μA - Reverse leakage per element, affects standby power and reliability |
| Case Isolation | 1500 V - Dielectric strength between metal base and terminals for safety compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15J (ON Semiconductor) | Same 15A/800V rating, but GBU package has lower RθJC (4.0°C/W) and no integrated heatsink | Requires external heatsink mounting; lacks 1500V case isolation | Prefer when board-level thermal management is optimized and UL isolation not required |
| KBP1508 (Comchip) | Identical electrical specs, but KBP package uses lead-forming instead of screw-mount; 1200V isolation | No screw hole; smaller footprint; higher isolation margin | Choose for space-constrained designs where mechanical mounting differs and enhanced isolation is beneficial |
Compared with GBPC1508, GBU15J offers better thermal resistance but sacrifices integrated heatsink and safety isolation, while KBP1508 matches performance in a smaller, non-screw-mount form with higher isolation - making GBPC1508 optimal for mechanically secured, safety-certified industrial power stages.

FAQ
What is the maximum case temperature for continuous operation of GBPC1508?
The GBPC1508 is rated for continuous operation at a case temperature (TC) of 70°C to deliver its full 15A average output current. Operation above this temperature requires linear derating per Figure 1 in the datasheet - e.g., ~10A at TC = 100°C - and must maintain junction temperature below 150°C using appropriate heatsinking.
Does GBPC1508 require a heatsink for 15A operation?
Yes. At 15A average current and TA = 25°C, the device's 5.0°C/W junction-to-case thermal resistance necessitates a heatsink to limit TJ ≤ 150°C. Diodes specifies a 220 × 220 × 50 mm aluminum plate for full-rated operation; smaller heatsinks require current derating per the derating curve.
Can GBPC1508 be used with capacitive loads?
Yes, but with 20% current derating applied to the 15A rating. Capacitive loads cause higher peak charging currents and increased RMS current stress, raising conduction losses and thermal load - the datasheet explicitly mandates this derating to ensure reliability and prevent overheating.
Is GBPC1508 RoHS compliant and lead-free?
Yes. GBPC1508 is RoHS compliant (EU Directive 2002/95/EC) with lead-free finish, as confirmed in Note 4 of the datasheet. Devices with date code 0514 and later meet RoHS requirements; plating is silver, and leads are solderable per MIL-STD-202, Method 208.
