Product details
Overview
PBPC1003 from Diodes Incorporated is a 200V peak repetitive reverse voltage, 10A average rectified output current (at TC = 50°C, mounted on metal chassis), single-phase bridge rectifier in PBPC-8 through-hole package with 150A non-repetitive surge rating and 1.1V forward voltage per element at 5.0A - used in AC/DC front-end conversion for industrial power supplies.
For engineers reviewing the PBPC1003 datasheet, PBPC1003 pinout, PBPC1003 application, or PBPC1003 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (7.5°C/W junction-to-case), mounting torque limit (5.0 in-lbs), and UL recognition status (E94661) for safety-compliant designs.
Technical Context
The PBPC1003 integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling AC input rectification without external interconnection. Its PBPC-8 case supports through-hole mounting with #6 screw and features molded plastic housing rated UL 94V-0.
Thermal performance is defined by two distinct derating curves: 10A at TC = 50°C on metal chassis, reduced to 8.0A when mounted on FR-4 PCB. Reverse leakage is specified as 10µA at 25°C and 1.0mA at 100°C per element under rated DC blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage the device withstands without breakdown during normal operation |
| IO @ TC=50°C | 10 A - Average rectified output current sustainable with metal-chassis heatsinking |
| IFSM | 150 A - Surge current capability for 8.3ms half-sine wave, critical for inrush handling |
| VFM @ IF=5.0A | 1.1 V - Forward voltage drop per diode element, directly impacts conduction loss and thermal design |
| RθJC | 7.5 °C/W - Junction-to-case thermal resistance, determines required heatsink interface performance |
| IR @ 25°C | 10 µA - Peak reverse leakage per element at rated voltage and room temperature |
| CT @ 1MHz | 110 pF - Typical junction capacitance per element, relevant for EMI filtering and high-frequency behavior |
Pinout & Package

Applications
| Industrial AC/DC Power Supplies | Motor Drive Front-End Rectifiers |
|---|---|
Use Scenario: 230VAC input stage in DIN-rail mounted 24V/48V industrial power supplies powering PLCs and sensors. IC Role / Device Role / Timing Role: Bridge rectifier converting AC line to unregulated DC bus prior to bulk capacitance and switching regulation. Use Value: 10A IO rating and 150A surge capacity support continuous operation under motor startup surges and brownout recovery. | Use Scenario: Single-phase AC input rectification in variable frequency drives for HVAC blowers and conveyor systems. IC Role / Device Role / Timing Role: Full-wave bridge providing DC link voltage for inverter stage; mounted directly to metal chassis for thermal management. Use Value: 7.5°C/W RθJC enables direct chassis heatsinking without additional thermal interface material, reducing BOM cost and footprint. |
| Test Equipment Power Modules | LED Driver Input Stages |
Use Scenario: Benchtop power analyzers and programmable DC sources requiring stable, low-noise DC bus generation. IC Role / Device Role / Timing Role: Primary rectifier in linear-regulated or hybrid SMPS architectures where low ripple and reliability are critical. Use Value: 10µA IR at 25°C minimizes standby leakage, supporting low-power sleep modes and accurate low-load measurements. | Use Scenario: Off-line LED drivers for street lighting and high-bay fixtures operating from 230VAC mains. IC Role / Device Role / Timing Role: Input bridge rectifier feeding constant-current buck or flyback controller ICs. Use Value: UL recognition (E94661) simplifies end-product safety certification and reduces time-to-market for Class II LED systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K | Same 200V VRRM, but 2A IO rating and GBU-4 package; lower surge (60A) | Not suitable for 10A continuous loads; limited to low-power adapters | Select only if board space is constrained and thermal budget permits forced-air cooling |
| GBU6K | 200V VRRM, 6A IO, GBU-4 package; 100A IFSM; higher RθJC (10°C/W) | Acceptable for intermittent 10A loads with active cooling; not chassis-mountable | Prefer for compact PCB layouts where screw mounting is impractical and thermal margin exists |
Compared with PBPC1003, GBU2K lacks sufficient current rating for sustained 10A operation, while GBU6K trades chassis-mount thermal advantage for smaller footprint but requires careful thermal design due to higher junction-to-ambient resistance.

FAQ
Is PBPC1003 RoHS compliant?
Yes, PBPC1003 meets RoHS Directive 2011/65/EU requirements. Lead-free plating is applied to all terminals, and the molded plastic case contains no restricted substances above threshold limits. Compliance documentation is available upon request for qualifying orders.
What is the maximum recommended mounting torque for PBPC1003?
The datasheet specifies a maximum mounting torque of 5.0 inch-pounds for the #6 screw used to secure the PBPC1003 to metal chassis. Exceeding this value risks cracking the PBPC-8 case or deforming internal lead frames, potentially compromising dielectric strength and thermal performance.
Can PBPC1003 be used with capacitive loads?
Yes, but with 20% current derating: the datasheet explicitly states that IO must be reduced by 20% for capacitive loads due to higher peak currents. At TC = 50°C, this limits usable average current to 8.0A instead of 10A, requiring verification of thermal margin under worst-case load conditions.
Does PBPC1003 require heatsinking when mounted on FR-4 PCB?
Yes - when mounted on FR-4 PCB (not metal chassis), the datasheet rates IO at only 8.0A at TC = 50°C. Without supplemental heatsinking or airflow, junction temperature will exceed 125°C under full load; copper pour area, thermal vias, and board-level airflow must be designed per the derating curve in Figure 1.
