Product details
Overview
PBPC803 from Diodes Incorporated is a through-hole 8.0A, 200V peak repetitive reverse voltage (VRRM) bridge rectifier in PBPC-8 package, configured as a single-phase full-wave AC-to-DC converter with four internal diodes. It delivers 8.0A average rectified output current at TC = 50°C (PCB mount), supports 125A non-repetitive surge current (8.3ms), and features 1.1V forward voltage per element at 4.0A - used in industrial power supplies and AC motor control input stages.
For engineers reviewing the PBPC803 datasheet, PBPC803 pinout, PBPC803 application, or PBPC803 equivalent, key selection criteria include VRRM rating for mains input margin, thermal resistance (9.4°C/W junction-to-case), surge capability for inrush handling, and PBPC-8 mechanical compatibility with #6 screw mounting.
Technical Context
The PBPC803 integrates four silicon PN-junction diodes in a single-phase bridge configuration, enabling full-wave rectification without external interconnects. Its 200V VRRM and 140V VR(RMS) rating target 115VAC nominal input systems with safety margin against line transients.
Thermal performance is defined by RθJC = 9.4°C/W per element and derating to 6.0A at TC = 100°C. The device uses molded plastic case (UL 94V-0), rated for -65°C to +125°C operation, and meets UL E94661 recognition for safety-critical PCB mounting.
Key Specifications

FAQ
What is the maximum case temperature for full-rated current operation?
The PBPC803 delivers its full 8.0A average output current only when case temperature (TC) is maintained at 50°C, typically achieved using FR-4 PCB with adequate copper area or chassis mounting. Above 50°C, current must be linearly derated per Figure 1 in the datasheet, reaching 6.0A at TC = 100°C.
Is PBPC803 RoHS compliant and lead-free?
Yes, PBPC803 is RoHS compliant and lead-free. Diodes Incorporated confirms compliance with EU Directive 2011/65/EU and China RoHS II, with lead-free plating on terminals and halogen-free molding compound meeting JEDEC J-STD-020C moisture sensitivity Level 1 requirements.
Can PBPC803 replace PBPC802 in an existing design?
Yes, PBPC803 is a direct upgrade from PBPC802: both share identical PBPC-8 package, pinout, and thermal characteristics, but PBPC803 offers higher VRRM (200V vs. 100V) and same 8.0A IO rating. No layout or thermal redesign is needed if the 200V rating satisfies system overvoltage requirements.
Why is PBPC803 marked "Not Recommended for New Design"?
Diodes Incorporated issued this notice due to planned obsolescence - newer alternatives like the GBU8K (same ratings, improved thermal resistance) or surface-mount GBPCxx series offer better efficiency or assembly compatibility. PBPC803 remains fully supported for legacy production and repair, with no immediate discontinuation.
