Product details
Overview
PBPC1004 from Diodes Incorporated is a 400V peak repetitive reverse voltage, 10A average rectified output current (at TC = 50°C on metal chassis), through-hole PBPC-8 packaged bridge rectifier with 150A non-repetitive peak forward surge capability and 1.1V typical forward voltage per element at 5.0A - used in AC/DC front-end conversion for industrial power supplies and motor control input stages.
For engineers reviewing the PBPC1004 datasheet, PBPC1004 pinout, PBPC1004 application, or PBPC1004 equivalent, key selection criteria include its 400V VRRM rating, 7.5°C/W junction-to-case thermal resistance, 150A IFSM surge tolerance, and PBPC-8 mechanical mounting configuration for #6 screw attachment.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a common anode–common cathode configuration, optimized for 60Hz line-frequency operation with resistive or inductive loads. Its 1500V case dielectric strength enables safe isolation in mains-connected equipment.
Thermal derating is defined for two mounting conditions: metal chassis (10A IO @ TC = 50°C) and FR-4 PCB (8.0A IO @ TC = 50°C). Capacitive load operation requires 20% current derating due to higher peak currents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage each diode can block without breakdown; defines maximum AC input voltage compatibility (e.g., 280V RMS). |
| IO (TC = 50°C) | 10 A - Continuous DC output current when mounted on metal chassis; sets minimum heatsink requirement for sustained 10A operation. |
| IFSM | 150 A - Single half-sine surge current tolerance (8.3ms); supports inrush current handling during cold-start of transformer-based supplies. |
| VFM (per element) | 1.1 V @ 5.0A - Forward voltage drop per diode; determines conduction loss (2.2V total bridge drop at 5A) and thermal dissipation. |
| RθJC | 7.5 °C/W - Thermal resistance from junction to case; enables direct calculation of junction temperature rise above heatsink temperature. |
| IR (25°C) | 10 µA - Peak reverse leakage per element at rated DC blocking voltage; ensures low standby power loss in high-impedance circuits. |
Pinout & Package
Package: PBPC-8 molded plastic case (UL 94V-0), through-hole mount with #6 screw hole; dimensions: 19.05 mm (A) × 7.0 mm (B) × 22.2 mm (C); weight ≈ 3.8 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal 1 | One of two alternating current input connections; tied internally to anode of D1 and cathode of D2 in full-wave bridge topology. |
| AC2 | AC Input Terminal 2 | Second AC input connection; tied internally to anode of D3 and cathode of D4 - forms complete bridge input pair. |
| + | DC Positive Output | Common cathode node of D1 and D3; delivers rectified positive DC output to filter capacitor or regulator stage. |
| − | DC Negative Output | Common anode node of D2 and D4; serves as return path for DC load current and system ground reference. |
Key Features
| Feature | Design Value |
|---|---|
| Surge Overload Rating | 150A peak (8.3ms half-sine) - enables reliable operation during transformer inrush and motor startup transients. |
| Case Dielectric Strength | 1500V - meets reinforced insulation requirements for Class I mains-connected equipment per IEC 62368-1. |
| Mounting Configuration | Through-hole with #6 screw hole - provides mechanical stability and low-thermal-resistance interface to metal chassis heatsinks. |
| Moisture Sensitivity | Level 1 per J-STD-020C - allows unlimited floor life before reflow; no baking required prior to assembly. |
Applications
| Industrial Power Supply Input Stage | Motor Drive AC Line Rectification |
|---|---|
Use Scenario: Converts 230VAC mains to unregulated DC bus in DIN-rail mounted 24V/48V industrial PSUs. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing primary AC-to-DC conversion before bulk capacitor filtering and downstream regulation. Use Value: 400V VRRM and 150A IFSM ensure robustness against 230VAC ±10% variation and transformer saturation surges. | Use Scenario: Rectifies AC line input for variable frequency drive (VFD) DC bus in HVAC blower systems. IC Role / Device Role / Timing Role: Front-end bridge delivering high-current DC bus to IGBT inverter stage; mounted directly to aluminum chassis for thermal management. Use Value: 7.5°C/W RθJC enables direct bolt-down heatsinking, maintaining junction temperature <125°C under 10A continuous load. |
| Welding Equipment Primary Rectification | UPS Input Stage |
Use Scenario: High-current rectification in single-phase input stage of portable arc welding machines. IC Role / Device Role / Timing Role: Handles intermittent 10A+ load pulses with >100A surge peaks during electrode striking. Use Value: 150A IFSM rating exceeds typical welding strike surge (120A), preventing thermal runaway during repeated duty cycles. | Use Scenario: Mains rectification in line-interactive UPS units with battery backup and AVR functionality. IC Role / Device Role / Timing Role: Provides isolated DC bus for bidirectional inverter and battery charging circuitry. Use Value: 1500V case dielectric strength satisfies creepage/clearance requirements for double-insulated UPS enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same 400V VRRM, 4A IO (PCB), 100A IFSM; GBU-4 package with lower current rating and smaller footprint. | Designed for compact PCB-mount designs where space limits heatsink area; not rated for 10A chassis-mount operation. | Select when board space is constrained and peak load remains ≤4A; avoid for 10A continuous chassis-mount use. |
| GBU8J (Vishay) | 600V VRRM, 8A IO (PCB), 200A IFSM; same GBU-8 package outline but higher voltage and surge rating. | Suitable for 380VAC three-phase input or 230VAC with elevated surge margin; higher VRRM increases cost and forward drop slightly. | Choose when designing for global mains (380VAC) or requiring extended surge immunity beyond 150A. |
Compared with GBU4K and GBU8J, PBPC1004 uniquely balances 10A chassis-mount capability, 400V rating, and PBPC-8 screw-mount mechanical stability - making it optimal for industrial power supplies where thermal mass and mechanical ruggedness outweigh miniaturization needs.

FAQ
What is the maximum operating temperature for PBPC1004?
PBPC1004 has an operating junction temperature range of −65°C to +125°C. Its maximum case temperature is limited by thermal derating curves: at TC = 50°C, it delivers 10A on metal chassis; above that, current must be reduced per Figure 1. Sustained operation above 125°C risks permanent parametric shift or failure.
Can PBPC1004 be used on a standard FR-4 PCB without a heatsink?
Yes, but with reduced current capacity: IO drops to 8.0A at TC = 50°C when mounted on FR-4 PCB (per datasheet Note 2). For continuous 8A operation, adequate copper pour (≥2 in², 2 oz Cu) and airflow are required; exceeding this without thermal management risks exceeding Tj = 125°C.
Is PBPC1004 RoHS compliant and halogen-free?
Yes. PBPC1004 meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molded plastic case uses UL 94V-0 compliant material, and lead finishes are matte tin-plated per JEDEC J-STD-020C moisture sensitivity Level 1.
Why is PBPC1004 marked "NOT RECOMMENDED FOR NEW DESIGN"?
This designation indicates Diodes Incorporated has introduced newer-generation alternatives (e.g., higher efficiency, smaller packages, or improved surge ratings) and will eventually phase out PBPC1004. It remains fully functional and supported for existing designs, with no immediate obsolescence - but new projects should evaluate successors like the GBU8J or future Diodes bridge families.
