Product details
Overview
PBPC805 from Diodes Incorporated is an 8.0A, 600V peak repetitive reverse voltage (VRRM) through-hole bridge rectifier in PBPC-8 package, rated for 8.0A average rectified output current at TC = 50°C with 1.1V forward voltage per element at 4.0A, used in AC/DC power supplies for industrial motor drives and HVAC control boards.
For engineers reviewing the PBPC805 datasheet, PBPC805 pinout, PBPC805 application, or PBPC805 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (9.4°C/W junction-to-case), surge rating (125A @ 8.3ms), and UL recognition (E94661) for safety-compliant board-level integration.
Technical Context
The PBPC805 integrates four silicon diodes in a single-phase full-wave bridge configuration, optimized for high-current AC line rectification with symmetrical terminal layout enabling direct PCB mounting via #6 screw. Its 1500V dielectric strength supports isolation compliance in Class I power systems.
Thermal performance relies on metal-chassis or FR-4 PCB mounting per note 1 and 2; derating curves specify 8.0A IO only at TC = 50°C, dropping to ~6.0A at 100°C case temperature. Capacitance is 100pF per element at 1MHz/4V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage before breakdown; defines AC input voltage limit (e.g., ≤420V RMS). |
| IO @ TC=50°C | 8.0 A - Continuous DC output current capability when case temperature held at 50°C; requires heatsinking or chassis mount. |
| VFM @ IF=4.0A | 1.1 V - Forward voltage drop per diode leg; determines conduction loss (≈4.4W total at 4A full-wave). |
| IFSM | 125 A - Non-repetitive surge current tolerance for 8.3ms half-sine; withstands inrush from transformer-coupled inputs. |
| RθJC | 9.4 °C/W - Thermal resistance from junction to case; enables thermal design using measured case temperature. |
| CT per element | 100 pF - Junction capacitance at 1MHz/4V reverse bias; impacts EMI filtering and high-frequency switching noise. |
Pinout & Package
Package: PBPC-8, molded plastic case (UL 94V-0), through-hole mount with #6 screw hole; terminals are plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal 1 | One of two symmetrical AC input nodes; accepts line or neutral in full-wave bridge configuration. |
| AC2 | AC Input Terminal 2 | Second AC input node; polarity agnostic-enables bidirectional AC connection without orientation dependency. |
| + | DC Output Anode | Positive DC output node; connects to bulk capacitor or downstream regulator input. |
| − | DC Output Cathode | Reference/return path for rectified DC; must be tied to system ground or negative rail. |
Key Features
| Feature | Design Value |
|---|---|
| UL Recognition | E94661 - Enables use in certified end equipment without additional component-level safety testing. |
| Surge Rating | 125A IFSM - Supports robust startup under heavy capacitive loads typical in industrial SMPS front-ends. |
| Dielectric Strength | 1500V - Meets reinforced insulation requirements for primary-secondary isolation in offline converters. |
| Moisture Sensitivity | Level 1 per J-STD-020C - No bake requirement prior to reflow; compatible with standard PCBA assembly flow. |

Use Value: 100pF per-element capacitance minimizes RF noise coupling into sensitive lamp control timing circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K | Same 8A/800V rating but GBU package (smaller footprint, lower IFSM = 100A) | Limited surge margin for high-inrush motor start; less suitable for 240VAC industrial loads | Select if space-constrained and surge demands are ≤100A |
| GBU8J | 8A/600V rating, GBU package, same IFSM = 100A, higher VFM = 1.15V | Higher conduction loss (≈4.6W vs 4.4W); reduced efficiency in thermally limited designs | Select if GBU footprint required and 0.05V VFM increase is acceptable |
Compared with PBPC805, GBU8K offers smaller size but sacrifices 20% surge capacity, while GBU8J matches voltage rating but increases conduction loss and reduces thermal margin-PBPC805 remains optimal where UL recognition, 125A surge, and 1500V isolation are mandatory.

FAQ
Is PBPC805 RoHS compliant and halogen-free?
Yes. PBPC805 meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molded plastic case uses UL 94V-0 compliant material, and plating conforms to JEDEC J-STD-609A Class 1 for marking and identification.
Can PBPC805 be mounted directly to a heatsink?
No. PBPC805 uses a plastic PBPC-8 case with internal thermal path to the metal screw-mounting pad-not a metal tab. Effective heat dissipation requires mounting to a metal chassis or thick copper PCB plane per note 1; external heatsinks are not electrically or thermally coupled to the die.
What is the minimum creepage distance for PBPC805 in PCB layout?
The PBPC-8 package provides ≥5.0mm creepage between AC1/AC2 and +/− terminals, validated per UL 94V-0 and IPC-2221B. For 600V working voltage, maintain ≥6.4mm trace separation on FR-4 to meet IEC 62368-1 basic insulation requirements.
Why is PBPC805 marked "Not Recommended for New Design"?
This designation reflects Diodes Incorporated's strategic shift toward surface-mount alternatives (e.g., GBU, KBU series) with improved automation compatibility and thermal performance. PBPC805 remains fully manufactured, supported, and qualified-no obsolescence or reliability concerns exist for existing designs.
