Product details
Overview
PBPC806 from Diodes Incorporated is an 8.0A through-hole bridge rectifier with 800V peak repetitive reverse voltage (VRRM), 125A non-repetitive surge rating (IFSM), and 1.1V forward voltage at 4.0A per element - designed for AC-to-DC conversion in industrial power supplies, motor controls, and HVAC systems.
For engineers reviewing the PBPC806 datasheet, PBPC806 pinout, PBPC806 application, or PBPC806 equivalent, key selection criteria include its PBPC-8 package thermal resistance (9.4°C/W), 1500V dielectric strength, UL recognition (E94661), and derating behavior above 50°C case temperature.
Technical Context
The PBPC806 integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling bidirectional AC input rectification to unidirectional DC output. Its 800V VRRM rating supports operation across 400–480VAC industrial mains with margin.
Thermal performance is defined by junction-to-case resistance of 9.4°C/W per element and requires metal-chassis mounting for full 8.0A IO rating; PCB-mounted derating reduces average current to 6.0A at TC = 50°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands peak reverse voltage up to 800V without breakdown; suitable for 480VAC line applications with safety margin. |
| IO @ TC=50°C (PCB) | 6.0 A - Maximum continuous DC output current when mounted on FR-4 PCB at 50°C case temperature. |
| IFSM (8.3ms) | 125 A - Surge withstand capability for short-duration line transients or inrush events. |
| VFM @ IF=4.0A | 1.1 V - Forward voltage drop per diode element; determines conduction loss and thermal load at rated current. |
| RθJC | 9.4 °C/W - Thermal resistance from junction to case per element; critical for heatsink sizing when chassis-mounted. |
| IR @ 25°C | 10 µA - Peak reverse leakage per element at rated blocking voltage; ensures low standby power loss. |
| Dielectric Strength | 1500 V - Minimum isolation voltage between AC terminals and case; meets reinforced insulation requirements. |
Pinout & Package
Package: PBPC-8, molded plastic case (UL 94V-0), through-hole mount with #6 screw mounting option; dimensions: 19.05 mm (A) × 7.0 mm (B) × 22.2 mm (C); weight ≈ 5.4 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal | One of two alternating-current input connections; symmetrical with AC2 for full-wave bridge operation. |
| AC2 | AC Input Terminal | Second AC input terminal; forms complete bridge input pair with AC1. |
| + | DC Output Anode | Positive DC output node; connects to bulk capacitor or downstream regulator input. |
| − | DC Output Cathode | Negative DC output node; serves as system ground reference for rectified output. |
Key Features
| Feature | Design Value |
|---|---|
| High surge rating | 125A IFSM enables reliable operation during motor startup or transformer inrush without failure. |
| UL Recognized Component | E94661 certification confirms compliance with safety standards for end-equipment approvals. |
| 1500V dielectric strength | Provides reinforced insulation barrier between AC inputs and chassis ground in Class I equipment. |
| Low forward voltage | 1.1V VFM at 4A minimizes conduction loss and improves efficiency in high-current DC bus designs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | Same PBPC-8 package, 800V VRRM, but 8.0A IO rated at TC=75°C (not 50°C); 1.1V VFM identical. | Higher thermal derating threshold allows full 8.0A use with better heatsinking; less conservative PCB-only rating. | Select GBU8K if chassis-mount heatsinking is available and higher ambient case temperature is expected. |
| GBU8J (Vishay) | Same 800V/8A rating, PBPC-8 package, but 1.05V VFM and 110A IFSM; UL E151271 vs. E94661. | Slightly lower conduction loss and reduced surge margin; different UL file number may require re-certification. | Choose GBU8J where efficiency gain justifies revalidation of safety documentation. |
Compared with GBU8K and GBU8J, PBPC806 offers the most conservative PCB-mounted current rating (6.0A) and highest surge margin (125A), making it preferred for cost-sensitive, thermally constrained industrial designs where safety margin outweighs marginal efficiency gains.

FAQ
Is PBPC806 RoHS compliant and lead-free?
Yes, PBPC806 is RoHS compliant and lead-free per Diodes Incorporated's standard specifications. The device uses lead-free plating on solderable leads and conforms to JEDEC J-STD-020C moisture sensitivity level 1, allowing unlimited floor life before reflow.
What is the maximum recommended mounting torque for PBPC806?
The maximum mounting torque for PBPC806 is 5.0 inch-pounds when secured with a #6 screw. Exceeding this value risks cracking the molded PBPC-8 plastic case or damaging internal wire bonds, potentially compromising dielectric strength or thermal path integrity.
Can PBPC806 be used in capacitive-load applications?
No - PBPC806 must be derated by 20% in capacitive-load configurations due to high inrush current. For example, its 6.0A PCB-rated current drops to 4.8A when feeding bulk electrolytic capacitors directly, as specified in the datasheet's derating note.
Why is PBPC806 marked "NOT RECOMMENDED FOR NEW DESIGN"?
This designation indicates Diodes Incorporated has introduced newer-generation bridge rectifiers (e.g., GBU8K, GBU10K) with improved thermal performance or packaging. PBPC806 remains fully qualified and supported for legacy production and repair, but new designs should evaluate alternatives for long-term supply assurance.
