Product details
Overview
PB62 from Diodes Incorporated is a 6.0A single-phase bridge rectifier in PB-6 plastic package, rated for 200V maximum recurrent peak reverse voltage (VRRM), 1.1V max forward voltage drop at 3.0A DC per leg, and 125A peak surge current (IFSM). It serves as AC-to-DC conversion front-end in offline power supplies for industrial control panels.
For engineers reviewing the PB62 datasheet, PB62 pinout, PB62 application, or PB62 equivalent, key selection criteria include VRRM margin for 120/240VAC inputs, thermal resistance (RθJC = 8°C/W) for heatsink-limited designs, IFSM capability under cold-start surge, and RoHS-compliant lead-free finish (date code 0514+).
Technical Context
The PB62 integrates four silicon junction diodes in a single-phase full-wave bridge configuration with marked polarity symbols on the body. Its PB-6 case supports soldering per MIL-STD-202 Method 208 and carries UL 94V-0 flammability rating.
Designed for resistive or inductive loads at 60Hz, it delivers 6.0A average forward rectified output current at heatsink temperature (THS) of 50°C, derating linearly to zero at ~125°C per Fig. 1, and exhibits 10µA max reverse leakage at 25°C and 1mA at 100°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands 200V peak reverse voltage per leg; suitable for 120VAC mains with 2× safety margin |
| I(AV) | 6.0 A - Continuous DC output current at 50°C heatsink temp; defines minimum heatsink requirement |
| IFSM | 125 A - Survives 8.3ms half-sine surge; handles inrush into capacitive input filters |
| VF | 1.1 V - Max forward drop per diode leg at 3.0A DC; determines conduction loss (≈2.2W total at full load) |
| RθJC | 8 °C/W - Junction-to-case thermal resistance; enables thermal design using heatsink interface data |
| IR @ 25°C | 10 µA - Max reverse leakage per leg at room temp; critical for low-power standby regulation |
| TJ Range | –65 to +150 °C - Operating junction temperature range; supports industrial ambient extremes |
Pinout & Package
PB62 uses the PB-6 molded plastic package (14.73–15.75 mm length, 5.84–6.86 mm width, 19 mm height, 4.56 g weight), with tinned copper leads solderable per MIL-STD-202 Method 208 and polarity symbols marked on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal | One of two alternating-current input nodes; connects to live/neutral of transformer secondary |
| AC2 | AC Input Terminal | Second AC input node; completes full-wave bridge input path with AC1 |
| + | DC Positive Output | Full-wave rectified positive DC output; feeds bulk capacitor or regulator input |
| – | DC Negative Output | Full-wave rectified negative DC output (circuit common); referenced to system ground |
Key Features
| Feature | Design Value |
|---|---|
| UL 94V-0 certified plastic case | Meets flame-retardant safety standard for PCB mounting in enclosed industrial enclosures |
| 125A peak surge rating | Withstands cold-start inrush surges without degradation in 120VAC/60Hz systems |
| Lead-free, RoHS-compliant finish | Complies with EU Directive 2002/95/EC for environmentally restricted markets (date code 0514+) |
| Low VF (1.1V @ 3A) | Reduces conduction losses by ~15% vs. legacy 1.3V bridges, improving efficiency in 5–24V DC outputs |
| 6.0A average current rating | Supports continuous 30W–60W output power depending on heatsink thermal design |
Applications
| Industrial AC-DC Power Supply | Motor Drive Control Board |
|---|---|

IC Role / Device Role / Timing Role: Mains-input bridge rectifier delivering stable DC to internal linear regulators and display drivers. Use Value: UL 94V-0 case and RoHS compliance meet safety and environmental requirements for CE-marked test gear. |
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 PB-6 package, 6.0A I(AV), but 800V VRRM and higher VF (1.2V) | Better suited for 240VAC-only or universal-input designs needing higher voltage margin | Select when >400V reverse stress is expected; avoid if low conduction loss is critical |
| KBPC602 (Shindengen) | Identical 200V VRRM and 6.0A rating, but KBPC package (larger footprint, RθJC = 6.5°C/W) | Offers lower thermal resistance but requires more PCB area and different mounting | Prefer for thermally constrained layouts where heatsink interface dominates; verify board cutout compatibility |
Compared with PB62, GBU6K trades lower VF for higher VRRM-beneficial in high-line designs but less efficient at 120VAC-while KBPC602 improves thermal performance at the cost of board space and mechanical fit, requiring layout revision.

FAQ
What is the maximum heatsink temperature at which PB62 delivers its full 6.0A rating?
PB62 delivers its full 6.0A average forward rectified output current only when the heatsink temperature (THS) is maintained at 50°C, as specified in the Absolute Maximum Ratings table. Above 50°C, current must be linearly derated per Figure 1 in the datasheet, reaching zero at approximately 125°C heatsink temperature.
Does PB62 support surface-mount assembly?
No, PB62 uses through-hole PB-6 packaging with axial leads designed for wave or hand soldering per MIL-STD-202 Method 208. It lacks SMD-compatible terminations or land patterns, and its 19mm height and 4.56g mass make it unsuitable for reflow processes or automated pick-and-place.
How does PB62's 10µA reverse leakage at 25°C impact low-power standby circuits?
At 10µA max per leg, PB62 contributes negligible leakage current in standby mode-well below typical microcontroller sleep currents (1–10µA). This ensures minimal battery drain or auxiliary supply loading in always-on monitoring circuits powered from rectified AC sources.
Is PB62 recommended for new designs according to Diodes Incorporated?
No-Diodes Incorporated explicitly states "NOT RECOMMENDED FOR NEW DESIGNS" in the datasheet, directing users to the newer PBPC601–PBPC607 series. PB62 remains supported for legacy production and repair, but new designs should evaluate PBPC602 (200V) for improved efficiency and thermal performance.
