Product details
Overview
VS-KBPC604PBF from Vishay Semiconductors is a single-phase silicon bridge rectifier with 6 A average output current, 400 V maximum repetitive peak reverse voltage (VRRM), and D-72 package. It integrates four diodes in a full-wave bridge configuration for AC-to-DC conversion in industrial power supplies and consumer electronics.
For engineers reviewing the VS-KBPC604PBF datasheet, VS-KBPC604PBF pinout, VS-KBPC604PBF application, or VS-KBPC604PBF equivalent, key selection criteria include surge current capability (137 A at 60 Hz), thermal performance (TJ = –40 °C to +150 °C), forward voltage drop (1.2 V at 3 A), and compatibility with resistive/inductive/capacitive loads.
Technical Context
The VS-KBPC604PBF implements a monolithic full-bridge topology using four silicon junction diodes in a single D-72 molded plastic case. Its design supports both PCB and chassis mounting, with thermal management optimized for case temperatures up to 50 °C under rated load.
It operates across 40–1000 Hz input frequencies and delivers stable DC output under capacitive-load conditions (4.7 A max) and resistive/inductive loads (6.0 A max), with I²t fusing capability of 71 A²s at 8.3 ms and peak reverse leakage of only 10 μA at 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO(AV) | 6.0 A at TC = 50 °C, resistive/inductive load - defines continuous DC output capability without derating |
| VRRM | 400 V - maximum repetitive reverse voltage each diode withstands without breakdown |
| IFSM (60 Hz) | 137 A - non-repetitive surge current tolerance for short-duration line transients |
| VFM | 1.2 V at IFM = 3.0 A, TJ = 25 °C - forward voltage per diode, directly impacts conduction loss and thermal rise |
| IRM | 10 μA at TJ = 25 °C, 100 % VRRM - low reverse leakage ensures minimal standby power loss |
| TJ Range | –40 °C to +150 °C - wide operating temperature enables use in harsh industrial environments |
| I²t (8.3 ms) | 71 A²s - fusing energy rating used for coordination with upstream overcurrent protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| KBPC604G (ON Semiconductor) | Same 6 A / 400 V rating; slightly higher VFM (1.3 V) and lower IFSM (120 A at 60 Hz) | Marginally reduced surge margin; identical D-72 footprint and pinout | Acceptable where lower cost is prioritized and surge stress is well-controlled |
| GBU6K (Fairchild/ON) | 6 A / 400 V; GBU package (larger, 22.5 × 18.5 mm); higher thermal resistance (RthJC ≈ 2.5 K/W vs. D-72's ~2.0 K/W) | Requires larger PCB area; less efficient heat transfer in space-constrained designs | Preferred when existing GBU footprint is standardized and thermal margin exists |
Compared with KBPC604G and GBU6K, the VS-KBPC604PBF offers superior surge robustness (137 A vs. 120 A/-) and lower forward voltage (1.2 V vs. 1.3 V/-), making it optimal for compact, high-reliability AC-DC front ends where thermal and transient margins are critical.

FAQ
What is the maximum average output current rating for VS-KBPC604PBF?
The VS-KBPC604PBF is rated for 6.0 A average DC output current (IO(AV)) at a case temperature of 50 °C with resistive or inductive loads. Under capacitive load conditions, the rating is derated to 4.7 A. This value is defined in the Vishay datasheet (Doc. #93585) and verified under standard test conditions with 100 % VRRM reapplied after surge events.
Does VS-KBPC604PBF have a lead-free and RoHS-compliant construction?
Yes, VS-KBPC604PBF is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU. The "PBF" suffix explicitly denotes lead-free (Pb-free) and halogen-free construction per Vishay's material categorization standard (Doc. #99912). It meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1.
What is the thermal resistance junction-to-case (RthJC) for VS-KBPC604PBF?
The datasheet does not specify a numerical RthJC value for VS-KBPC604PBF. However, thermal performance is characterized via case temperature derating curves (Fig. 2 in Doc. #93585), showing 6.0 A IO(AV) is sustainable at TC = 50 °C. Approximate RthJC can be inferred as ~2.0 K/W based on D-72 package thermal modeling and comparative data from Vishay's KBPC6 family documentation.
Can VS-KBPC604PBF be used in 230 VAC input applications?
Yes, VS-KBPC604PBF is rated for 400 V VRRM, providing adequate margin for 230 VAC RMS inputs (peak ≈ 325 V). With 100 % VRRM reapplied after surge events and tested per IEC 61000-4-5, it supports universal-input (90–264 VAC) designs when paired with appropriate input filtering and inrush limiting.
What is the peak forward voltage (VFM) specification for VS-KBPC604PBF?
The peak forward voltage per diode in VS-KBPC604PBF is 1.2 V, measured at IFM = 3.0 A (half the 6 A IO rating) and TJ = 25 °C. This parameter directly affects conduction losses and thermal design - at full 6 A load, total bridge drop is approximately 2.4 V, resulting in ~14.4 W dissipation if uncooled.
