Product details
Overview
PBPC604 from Diodes Incorporated is a 6.0A, 400V peak repetitive reverse voltage (VRRM) through-hole bridge rectifier in PBPC-6 package, featuring 125A non-repetitive surge current capability, 1.1V forward voltage at 3.0A per element, and 1500V case dielectric strength - used in AC/DC power supplies for industrial motor drives and HVAC control boards.
For engineers reviewing the PBPC604 datasheet, PBPC604 pinout, PBPC604 application, or PBPC604 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (12.5°C/W junction-to-case), mounting torque limit (5.0 in-lbs), and UL recognition (E94661) for safety-compliant board-level integration.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a common anode–common cathode configuration with marked polarity on the molded plastic case. It operates across -65°C to +125°C and requires chassis or FR-4 PCB mounting per derating curves.
Rated for 60Hz resistive/inductive loads, it mandates 20% average current derating under capacitive load conditions. Its 55pF typical capacitance per element (measured at 1MHz, 4V reverse bias) supports stable high-frequency rectification without parasitic resonance in switching supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage the device blocks without breakdown; defines maximum AC input voltage rating before rectification. |
| IO @ TC=50°C | 6.0 A - Average DC output current sustainable when case temperature is held at 50°C on metal chassis mounting. |
| IFSM | 125 A - Non-repetitive 8.3ms half-sine surge current tolerance; determines inrush survivability during power-up. |
| VFM @ IF=3.0A | 1.1 V - Forward voltage drop per diode element; directly impacts conduction loss and thermal design of 6A-rated supplies. |
| RθJC | 12.5 °C/W - Thermal resistance from junction to case; enables heatsink sizing when mounted to metal chassis with thermal interface. |
| IR @ 100°C | 1.0 mA - Peak reverse leakage per element at elevated temperature; critical for low-power standby circuit integrity. |
| CT per element | 55 pF - Junction capacitance measured at 1MHz/4V; influences EMI filtering requirements and high-frequency rectifier stability. |
Pinout & Package
Package: PBPC-6, through-hole molded plastic case with #6 screw mounting hole (G = 3.60–4.00 mm Ø), UL 94V-0 flammability rating, and plating compliant with MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal 1 | One of two alternating current input connections; tied internally to anode of D1 and cathode of D2 in full-wave bridge topology. |
| AC2 | AC Input Terminal 2 | Second AC input; tied internally to anode of D3 and cathode of D4 - forms complete bridge input pair. |
| + | DC Output Anode | Positive DC output node; internal connection point of cathodes of D1 and D3 - delivers rectified positive voltage. |
| - | DC Output Cathode | Negative DC output node; internal connection point of anodes of D2 and D4 - serves as return/reference rail. |
Key Features
| Feature | Design Value |
|---|---|
| 1500V case dielectric strength | Enables safe isolation between primary-side AC and secondary-side DC circuits in Class I insulated power supplies. |
| UL Recognized Component (E94661) | Validates compliance with UL 60747-4 for use in certified end equipment without additional system-level safety testing. |
| 12.5°C/W RθJC | Allows direct thermal coupling to metal chassis for passive cooling - eliminates need for discrete heatsinks in 6A designs. |
| Moisture Sensitivity Level 1 | Permits unlimited floor life and standard reflow/soldering without baking - simplifies manufacturing handling. |
| Marked polarity on body | Reduces assembly errors by visually indicating +, -, and AC terminals - critical for field service and repair. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same 400V VRRM and 6A IO, but GBU-4 package (smaller footprint, no screw mount); RθJC = 15°C/W. | Lacks #6 screw mounting and 1500V dielectric rating; unsuitable for safety-isolated or high-vibration environments. | Select when space-constrained PCB layout prioritizes footprint over mechanical ruggedness or safety isolation. |
| KBPC604 (Comchip) | Identical electrical specs (400V/6A/125A), KBPC-6 package with similar dimensions but no UL recognition or 1500V dielectric test data published. | Not UL-recognized; requires additional system-level safety validation for medical or industrial end equipment. | Select only for cost-sensitive, non-certified applications where external isolation and safety approvals are managed elsewhere. |
Compared with GBU4K and KBPC604, PBPC604 uniquely combines UL recognition, 1500V dielectric strength, and screw-mount mechanical stability - making it the only choice for safety-critical, high-reliability AC/DC front-ends requiring both regulatory compliance and physical durability.

FAQ
What is the maximum mounting torque for PBPC604?
The maximum recommended mounting torque for PBPC604 is 5.0 inch-pounds when securing the #6 screw through the G-hole (3.60–4.00 mm diameter). Exceeding this value risks cracking the molded PBPC-6 case or compromising internal wire bonds, leading to premature failure under thermal cycling or vibration.
Can PBPC604 be used with capacitive loads?
Yes, but with mandatory 20% derating of the average output current (IO). For example, the rated 6.0A must be reduced to 4.8A when feeding bulk capacitance directly after rectification - due to higher RMS current and peak diode stress caused by capacitor-input filter behavior.
Is PBPC604 RoHS compliant and lead-free?
Yes, PBPC604 is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU and JEDEC J-STD-609A Class 3 marking requirements. The terminal plating is matte tin over copper, solderable per MIL-STD-202 Method 208, and compatible with standard Pb-free reflow profiles.
What is the meaning of "PBPC-6" in the ordering information?
PBPC-6 denotes the proprietary Diodes Incorporated package type: a 4-terminal, through-hole, molded plastic bridge rectifier housing with integrated #6 screw mounting hole, standardized lead pitch, and UL 94V-0 flammability rating - distinct from industry-standard GBU, KBU, or KBPC packages in mechanical form and mounting capability.
