Diodes Incorporated PBPC804

Overview

PBPC804 from Diodes Incorporated is an 8.0A, 400V peak repetitive reverse voltage (VRRM) through-hole bridge rectifier in PBPC-8 package, featuring 125A non-repetitive surge capability, 1.1V forward voltage at 4.0A per element, and 1500V dielectric strength - used in AC/DC power supplies for industrial motor controls and HVAC system power stages.

For engineers reviewing the PBPC804 datasheet, PBPC804 pinout, PBPC804 application, or PBPC804 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (9.4°C/W junction-to-case), mounting torque limit (5.0 in-lbs), and UL recognition under file E94661.

Technical Context

The PBPC804 integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals. It operates under 60Hz single-phase AC input with defined derating curves for case temperature up to 125°C and supports both resistive and inductive loads.

Each diode element exhibits 10µA peak reverse current at 25°C and 1.0mA at 100°C under rated DC blocking voltage, with typical junction-to-case thermal resistance of 9.4°C/W and total capacitance of 100pF per element measured at 1MHz and 4.0V reverse bias.

FAQ

Is PBPC804 RoHS compliant?

Yes, PBPC804 meets RoHS Directive 2011/65/EU requirements. The device uses lead-free terminations and complies with JEDEC J-STD-020C moisture sensitivity level 1, verified per Diodes Incorporated's official product change notices and material declarations.

What is the maximum mounting torque for PBPC804?

The maximum recommended mounting torque for PBPC804 is 5.0 inch-pounds, as specified in the mechanical data section of DS21311 Rev. 8. Exceeding this value risks cracking the molded PBPC-8 case or damaging internal wire bonds.

Can PBPC804 be used with capacitive loads?

No - the datasheet explicitly requires 20% current derating for capacitive loads. At full 8.0A rating, PBPC804 is qualified only for resistive or inductive loads; capacitive loading increases peak current stress and must be accounted for in thermal design.

Does PBPC804 have UL recognition?

Yes, PBPC804 is UL Listed under Recognized Component Index File Number E94661. This applies to the entire PBPC-8 package family and covers dielectric strength, flammability (UL 94V-0), and construction per UL 60747-1 and UL 60950-1 standards.
