Product details
Overview
PBPC603 from Diodes Incorporated is a 6.0A, 200V peak repetitive reverse voltage (VRRM) single-phase bridge rectifier in PBPC-6 through-hole package, rated for 4.0A average output current on PCB mount, with 125A non-repetitive surge capability and 1.1V forward voltage at 3.0A per diode element-used in AC/DC power supplies for industrial control panels.
For engineers reviewing the PBPC603 datasheet, PBPC603 pinout, PBPC603 application, or PBPC603 equivalent, key selection criteria include VRRM rating, thermal derating on FR-4 board, IFSM surge margin, and mechanical mounting compatibility with #6 screw hardware.
Technical Context
This bridge rectifier integrates four silicon junction diodes in a single molded plastic case with marked polarity and isolated AC input terminals (+/- DC output). It operates across –65°C to +125°C and requires metal-chassis or PCB-mount thermal management per derating curves.
Each diode element exhibits 12.5°C/W junction-to-case thermal resistance, 55pF typical capacitance at 1MHz/4V reverse bias, and ≤10μA peak reverse leakage at 25°C-enabling stable operation under resistive, inductive, or lightly capacitive loads when derated by 20% for capacitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum peak reverse voltage each diode withstands without breakdown |
| IO (PCB) | 4.0 A - average rectified current sustainable on FR-4 board at 50°C case temperature |
| IFSM | 125 A - non-repetitive 8.3ms half-sine surge current handling capacity |
| VFM @ 3.0A | 1.1 V - forward voltage drop per diode element, defining conduction loss at rated load |
| RθJC | 12.5 °C/W - thermal resistance from junction to case, critical for heatsink interface design |
| IR @ 25°C | 10 μA - peak reverse leakage per element at rated DC blocking voltage and ambient temperature |
| Tj Range | –65°C to +125°C - operational junction temperature limits affecting long-term reliability |
Pinout & Package

| AC2 | AC Input Terminal | Second AC input terminal; forms full-wave bridge input pair with AC1 |
| + | DC Output Anode | Positive DC output node; connects internally to anode of two diodes conducting during positive half-cycles |
| – | DC Output Cathode | Negative DC output node; connects internally to cathode of two diodes conducting during negative half-cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 6.0A/200V rating but GBU-6 package; no integrated screw hole; 1.05V VFM | Requires external mounting hardware; better suited for compact SMT-dominant designs with heatsink clips | Select when board space is constrained and mechanical mounting flexibility is prioritized over integrated fastening |
| GBU6J (Vishay) | 6.0A/600V VRRM; higher voltage rating increases cost and size; 1.1V VFM matches PBPC603 | Over-spec'd for 120/240VAC inputs; used where future-proofing against voltage transients is required | Select only if system-level surge testing mandates >400V transient immunity on AC input |
Compared with GBU6K and GBU6J, PBPC603 offers unique mechanical integration via its PBPC-6 screw-mount design and optimal balance of 200V rating, 4.0A PCB current, and UL E94661 recognition for industrial enclosure-based power supplies.

FAQ
What is the maximum average output current for PBPC603 when mounted on a standard FR-4 PCB?
The PBPC603 delivers 4.0A average rectified output current when mounted on FR-4 PCB at a case temperature of 50°C, as specified in the datasheet's "Average Rectified Output Current" table under Note 2. This rating assumes natural convection cooling and no additional heatsinking.
Does PBPC603 require external heatsinking for continuous 4.0A operation?
No external heatsink is required for continuous 4.0A operation at TC = 50°C on FR-4, provided ambient conditions and board copper area meet the derating curve in Figure 1. However, for sustained operation above 50°C case temperature or higher current transients, chassis mounting or supplemental thermal mass is recommended.
Can PBPC603 be used with capacitive input filters without derating?
No. The datasheet explicitly requires a 20% current derating for capacitive-load applications due to increased peak currents and thermal stress. At full 4.0A PCB rating, usable current drops to 3.2A when feeding bulk capacitance directly after rectification.
Is PBPC603 compliant with RoHS and REACH regulations?
Yes. PBPC603 is RoHS-compliant (lead-free terminations, compliant with Directive 2011/65/EU) and REACH-conformant, as confirmed by Diodes Incorporated's material declarations and packaging documentation referenced in the ordering information section of DS21322 Rev. 8.
