Product details
Overview
PBPC605 from Diodes Incorporated is a 6.0A, 600V peak repetitive reverse voltage (VRRM) single-phase bridge rectifier in PBPC-6 through-hole package, designed for AC-to-DC conversion in industrial power supplies and motor control circuits, with 125A non-repetitive surge capability and 1.1V forward voltage at 3.0A per diode element.
For engineers reviewing the PBPC605 datasheet, PBPC605 pinout, PBPC605 application, or PBPC605 equivalent, key selection criteria include its 600V blocking rating, 6.0A average output current at TC = 50°C on PCB mount, 12.5°C/W thermal resistance per element, and UL recognition (E94661) for safety-critical power conversion designs.
Technical Context
The PBPC605 integrates four silicon junction diodes in a single-phase full-wave bridge configuration, enabling direct rectification of AC line input without external interconnection. Its PBPC-6 case features a #6 screw mounting hole and 1500V dielectric strength between case and terminals.
Rated for 60Hz resistive/inductive loads, it requires 20% current derating under capacitive load conditions. Thermal performance is specified for two mounting conditions: metal chassis (6.0A IO) and FR-4 PCB (4.0A IO), with junction-to-case thermal resistance of 12.5°C/W per diode element.

| IO @ TC=50°C (PCB) | 4.0 A - Continuous average rectified output current when mounted on FR-4 board |
| IFSM (8.3ms) | 125 A - Non-repetitive surge current handling for short-line transients or inrush |
| VFM @ IF=3.0A | 1.1 V - Forward voltage drop per diode element, directly impacting conduction loss |
| RθJC | 12.5 °C/W - Junction-to-case thermal resistance per diode, critical for heatsink sizing |
| IR @ 100°C | 1.0 mA - Peak reverse leakage per diode at elevated temperature, affecting standby loss |
| CT (1MHz) | 55 pF - Typical junction capacitance per diode, influencing high-frequency switching noise |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 600V VRRM, 6.0A IO (chassis mount), but GBU-4 package lacks screw mount and has higher RθJC (15°C/W) | Requires external heatsink for >3A continuous use; not suitable for direct chassis conduction cooling | Select when space-constrained PCB layout prioritizes smaller footprint over thermal performance |
| KBPC606 (Comchip) | 600V VRRM, 6.0A IO (chassis), PBPC-6 equivalent pinout, but IR = 5.0μA @25°C (vs. PBPC605's 10μA) | Lower leakage benefits low-power standby modes; identical mechanical interface enables drop-in replacement | Select when ultra-low reverse leakage is required for energy-efficient standby compliance |
Compared with GBU6K and KBPC606, PBPC605 uniquely combines UL recognition, screw-mount thermal path, and 125A surge rating-making it optimal for ruggedized industrial power supplies where reliability under transient stress and safety certification are mandatory.

FAQ
What is the maximum average output current for PBPC605 when mounted on a standard FR-4 PCB?
The PBPC605 delivers 4.0A average rectified output current when mounted on an FR-4 printed circuit board at case temperature TC = 50°C, as specified in the datasheet's "Maximum Ratings" table. This rating assumes no additional heatsinking and accounts for thermal limitations of the PCB layout and copper area.
Does PBPC605 require pre-baking before reflow soldering?
No. The PBPC605 is rated Moisture Sensitivity Level 1 per J-STD-020C, meaning it has unlimited floor life and does not require baking prior to PCB assembly-even after extended storage. This simplifies manufacturing logistics and reduces process risk in high-volume production.
Can PBPC605 be used with capacitive loads such as bulk electrolytic input capacitors?
Yes, but with 20% current derating applied to the average output current rating. For example, the 4.0A PCB-rated IO becomes 3.2A when driving a capacitive-input filter. This accounts for increased peak diode current and associated thermal stress during capacitor charging cycles.
What is the significance of the 1500V dielectric strength specification?
The 1500V case-to-terminal dielectric strength ensures safe isolation between live AC/DC terminals and the metal mounting surface (e.g., chassis or heatsink). It meets basic insulation requirements for Class I appliances and industrial equipment operating from 230V AC mains, preventing shock hazard and supporting UL/IEC safety certification.
