Diodes Incorporated PBPC602

Overview

PBPC602 from Diodes Incorporated is a 6.0A, 100V peak repetitive reverse voltage (VRRM) single-phase bridge rectifier in PBPC-6 through-hole package, rated for 125A non-repetitive surge current (IFSM), 1.1V forward voltage at 3.0A per element, and 10µA peak reverse current at 25°C - used in AC/DC power supplies for industrial control panels requiring high surge immunity and chassis-mount reliability.

For engineers reviewing the PBPC602 datasheet, PBPC602 pinout, PBPC602 application, or PBPC602 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (RθJC = 12.5°C/W per element), mounting torque limit (5.0 in-lb), and UL recognition (E94661) for safety-compliant board-level integration.

Technical Context

This bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with common-cathode and common-anode terminals. It operates under resistive/inductive loads at 60Hz, with mandatory 20% average current derating when used with capacitive input filters.

Thermal performance depends on mounting method: IO = 6.0A at TC = 50°C when mounted on metal chassis, but drops to 4.0A under identical conditions on FR-4 PCB. Junction-to-case thermal resistance is specified per diode element (12.5°C/W), not for the full bridge assembly.

Key Specifications

Pinout & Package

PBPC602 uses the PBPC-6 through-hole package: molded plastic case (UL 94V-0), #6 screw mounting hole (G = 3.6–4.0 mm Ø), 3.8g mass, and polarity marked on body. Mounting torque must not exceed 5.0 in-lb.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Compared with GBU6K and GBU6J, PBPC602 offers superior surge robustness (125A vs. 100A) and lower thermal resistance (12.5°C/W vs. ≥14°C/W), making it optimal for thermally demanding, high-inrush industrial power supplies where mechanical mounting to metal chassis is feasible.

FAQ

What is the maximum recommended mounting torque for PBPC602?

The datasheet specifies a maximum mounting torque of 5.0 inch-pounds for the #6 screw hole. Exceeding this value risks cracking the molded plastic case or deforming internal lead frames, potentially compromising dielectric strength and thermal conduction. Use a calibrated torque screwdriver during chassis installation.

Can PBPC602 be used with capacitive-input filter topologies?

Yes, but with mandatory 20% derating of average output current (IO). For example, the 6.0A rating drops to 4.8A when driving a bulk capacitor directly after the bridge. This accounts for increased RMS current and thermal stress caused by discontinuous conduction mode in capacitor-input designs.

How does thermal performance differ between chassis and PCB mounting?

When mounted on a metal chassis, PBPC602 delivers 6.0A at TC = 50°C; on FR-4 PCB, its rating falls to 4.0A under identical conditions. This 33% reduction reflects higher effective thermal resistance due to limited copper area and lack of direct metal conduction path in standard board mounting.

Is PBPC602 suitable for life support equipment?

No. Diodes Incorporated explicitly prohibits use of PBPC602 in life support devices or systems without written CEO approval. Its qualification excludes safety-critical applications where failure could cause injury, such as implantables or ventilator power stages, due to absence of ASIL or ISO 13485 process controls.
