Product details
Overview
PBPC802 from Diodes Incorporated is an 8.0A through-hole bridge rectifier with 100V peak repetitive reverse voltage (VRRM), 70V RMS reverse voltage, and 1.1V forward voltage at 4.0A per element-designed for AC-to-DC conversion in industrial power supplies, motor control PCBs, and appliance front-end rectification.
For engineers reviewing the PBPC802 datasheet, PBPC802 pinout, PBPC802 application, or PBPC802 equivalent, key selection criteria include its 125A non-repetitive surge rating, 9.4°C/W junction-to-case thermal resistance, UL recognition (E94661), and PBPC-8 molded plastic package with #6 screw mounting.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a common PBPC-8 case with marked polarity and plating compliant to MIL-STD-202 Method 208. It operates across –65°C to +125°C and requires derating to 6.0A when mounted on FR-4 PCBs at TC = 50°C.
Each internal diode exhibits 10µA peak reverse current at 25°C and 1.0mA at 100°C under rated DC blocking voltage, with typical junction capacitance of 100pF per element measured at 1.0MHz and 4.0V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum peak reverse voltage the device withstands repeatedly without breakdown |
| IO @ TC=50°C (PCB) | 6.0 A - average rectified output current when mounted on FR-4 board |
| IFSM | 125 A - non-repetitive surge current capability for 8.3ms half-sine wave |
| VFM @ IF=4.0A | 1.1 V - forward voltage drop per diode element, directly impacting conduction loss |
| RθJC | 9.4 °C/W - thermal resistance from junction to case, critical for heatsink interface design |
| IR @ 25°C | 10 µA - leakage current per element at rated blocking voltage and room temperature |
| CT @ 1MHz | 100 pF - junction capacitance per element, affecting high-frequency noise and EMI behavior |
Pinout & Package
Package: PBPC-8 molded plastic case, UL 94V-0 rated, with through-hole leads for #6 screw mounting and 5.0 inch-pounds max torque. Weight: 5.4g.
| Pin/Terminal | Circuit Role | Design Meaning |

| + | Positive DC output | Anode-side output node where rectified positive voltage is sourced to load |
| – | Negative DC output | Cathode-side return path; referenced as circuit ground or negative rail in unipolar supplies |
Key Features
| Feature | Design Value |
|---|---|

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 8.0A IO rating but 800V VRRM; PBPC802 has lower VRRM (100V) and higher surge (125A vs. 100A) | GBU8K suits 230VAC systems; PBPC802 optimized for 120VAC with tighter thermal margin | Select PBPC802 for cost-sensitive 120VAC designs requiring high surge immunity and UL recognition |
| GBU8D | 8.0A IO, 200V VRRM, 100A IFSM; smaller GBU package lacks screw mount and 1500V isolation | GBU8D used in compact PCB layouts; PBPC802 prioritizes mechanical ruggedness and safety isolation | Choose PBPC802 where chassis mounting, UL compliance, or 1500V isolation are mandatory |
Compared with GBU8K and GBU8D, PBPC802 trades higher voltage rating for superior surge robustness, certified safety isolation, and mechanical mounting-making it optimal for 120VAC industrial and appliance applications demanding long-term reliability and regulatory acceptance.

FAQ
Is PBPC802 RoHS compliant and halogen-free?
Yes. PBPC802 meets RoHS Directive 2011/65/EU requirements and is halogen-free per IEC 61249-2-21. The molded plastic case uses UL 94V-0 material with no brominated flame retardants, and lead finishes comply with JEDEC J-STD-020C moisture sensitivity Level 1.
What is the recommended PCB pad layout for PBPC802?
Diodes recommends copper pour areas ≥250 mm² per terminal (AC1, AC2, +, –) on external layers, connected via ≥3 thermal vias (0.3mm diameter) to inner ground/power planes. Pad dimensions should match PBPC-8 mechanical outline: 19.05mm × 7.0mm footprint with 2.38mm lead spacing and 1.27mm diameter holes.
Can PBPC802 be used in capacitive-input filter configurations?
No-capacitive-input filters require 20% derating of IO. For PBPC802, this reduces the usable average current from 6.0A to 4.8A on FR-4 PCBs. Diodes explicitly states this derating applies due to increased peak diode current and thermal stress; use inductive-input or choke-input filters is preferred for full-rated performance.
Why is PBPC802 marked "NOT RECOMMENDED FOR NEW DESIGN"?
This designation indicates Diodes has introduced newer-generation alternatives (e.g., GBU8J series) with improved thermal performance and tighter VFM distribution. PBPC802 remains fully manufactured and supported, but new designs should evaluate successors offering enhanced efficiency or smaller footprint while maintaining compatibility.
