Product details
Overview
PBPC1001 from Diodes Incorporated is a 10A through-hole bridge rectifier with 50V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 5A per element, and 150A non-repetitive surge capability. It uses a PBPC-8 molded plastic case rated UL 94V-0, features 1500V dielectric strength, and is designed for AC-to-DC conversion in industrial power supplies mounted on FR-4 PCBs.
For engineers reviewing the PBPC1001 datasheet, PBPC1001 pinout, PBPC1001 application, or PBPC1001 equivalent, key selection criteria include its 10A average output current at TC = 50°C (PCB mount), thermal resistance of 7.5°C/W (junction-to-case), and 110pF typical capacitance per element-critical for EMI-sensitive linear power supply designs.
Technical Context
The PBPC1001 integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling direct AC input rectification without external interconnection. Its PBPC-8 package supports #6 screw mounting and delivers 1500V isolation between AC terminals and case, meeting UL Recognized Component requirements (File E94661).
Rated for operation from –65°C to +125°C, it exhibits 10µA peak reverse current at 25°C and 1.0mA at 100°C under rated DC blocking voltage. Derating curves specify 10A IO only when mounted on metal chassis; PCB-mounted performance drops to 8.0A at TC = 50°C per datasheet Note 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum peak reverse voltage each diode withstands without breakdown; defines safe AC input range. |
| IO @ TC=50°C (PCB) | 8.0 A - Sustained DC output current when mounted on FR-4 board; requires heatsinking above ambient. |
| IFSM (8.3ms) | 150 A - Surge tolerance during cold-start or line transients; critical for reliability in unregulated supplies. |
| VFM @ IF=5.0A | 1.1 V - Forward drop per diode pair; determines conduction loss and thermal rise in 12V/24V systems. |
| RθJC | 7.5 °C/W - Junction-to-case thermal resistance; enables direct thermal interface to chassis or heatsink. |
| CT (per element) | 110 pF - Junction capacitance at 1MHz/4V; impacts high-frequency noise coupling in switching-adjacent rails. |

FAQ
What is the maximum continuous current rating for PBPC1001 when mounted on a standard FR-4 PCB?
The PBPC1001 delivers 8.0A average rectified output current when mounted on an FR-4 printed circuit board at case temperature TC = 50°C, as specified in Note 2 of the datasheet. This rating assumes no additional heatsinking and accounts for thermal limitations of the PCB layout and copper area.
Does PBPC1001 support screw mounting, and what is the recommended torque?
Yes, the PBPC1001's PBPC-8 package includes a central mounting hole designed for #6 screw attachment. The datasheet specifies a maximum mounting torque of 5.0 inch-pounds to avoid case cracking or internal lead damage while ensuring reliable mechanical and thermal contact to the chassis.
How does the 1500V dielectric strength impact system-level safety certification?
The 1500V isolation rating between AC terminals and case meets basic insulation requirements for many Class I industrial products under IEC 61000-4-5 and UL 60950-1. It eliminates need for additional creepage/clearance spacing on PCBs, simplifying layout for EN 62368-1 compliant designs.
Is PBPC1001 suitable for use in life support equipment?
No. Per Diodes Incorporated's Important Notice, PBPC1001 is explicitly not authorized for use in life support devices or systems without express written approval from Diodes' CEO. Its qualification excludes safety-critical medical applications requiring ASIL or ISO 13485 traceability.
