Product details

Overview

VS-KBPC106 from Vishay Semiconductors is a single-phase silicon bridge rectifier rated for 6 A average output current, 600 V maximum repetitive peak reverse voltage (V_RRM), and 137 A non-repetitive surge current at 60 Hz. It features four integrated diodes in a full-wave bridge configuration, compact D-72 package, and is designed for AC-to-DC conversion in industrial power supplies and consumer appliance mains input stages.

For engineers reviewing the VS-KBPC106 datasheet, VS-KBPC106 pinout, VS-KBPC106 application, or VS-KBPC106 equivalent, key selection criteria include its 600 V V_RRM, 6 A I_O(AV) at T_C = 50 °C, surge robustness (137 A I_FSM), thermal range (–40 to +150 °C), and D-72 mechanical footprint compatibility with PCB or chassis mounting.

Technical Context

The VS-KBPC106 implements a monolithic full-bridge topology using four silicon junction diodes, enabling unidirectional DC output from single-phase AC inputs without external wiring. Its thermal design supports operation up to +150 °C junction temperature, with case temperature derating curves confirming 6 A I_O(AV) only at T_C = 50 °C for resistive/inductive loads.

It delivers 1.2 V typical peak forward voltage per diode at I_FM = 3 A and 25 °C, and maintains ≤1.0 mA peak reverse leakage per diode at 100 % V_RRM and 150 °C - critical for low-loss, high-reliability rectification in 50/60 Hz line-frequency applications.

Key Specifications

Parameter	Value and Actual Design Meaning
I_O(AV)	6.0 A at T_C = 50 °C, resistive/inductive load - defines continuous DC output capability under standard heatsinking
V_RRM	600 V - maximum repetitive reverse voltage each diode withstands; sets usable AC input RMS limit to 250 V
I_FSM	137 A at 60 Hz, 8.3 ms - surge rating for inrush current handling during cold-start of capacitive-input supplies
V_FM	1.2 V typical per diode at I_FM = 3 A, 25 °C - determines conduction loss and thermal dissipation in forward bias
T_J Range	–40 °C to +150 °C - enables deployment in harsh industrial environments without derating penalties below –40 °C
I_R	1.0 mA max per diode at 100 % V_RRM, 150 °C - ensures minimal leakage-induced standby loss in high-temp operation

Pinout & Package

VS-KBPC106 uses the D-72 package: a molded plastic case with four axial leads (two AC inputs, one +DC output, one –DC output), 25.4 mm minimum length, 15.75 mm width, and 10.8 mm height. Mounting supports both PCB through-hole and chassis screw-down via lead bending.

Pin/Terminal	Circuit Role	Design Meaning
AC1 / AC2	AC Input Terminals	Accept single-phase AC input; internally connected to anode of D1/D2 and cathode of D3/D4 respectively
+	Positive DC Output	Common cathode node of D1 and D2; delivers rectified positive voltage to load/filter capacitor
–	Negative DC Output	Common anode node of D3 and D4; serves as return path and ground reference for DC output

Key Features

Feature	Design Value
High Surge Current Capability	137 A I_FSM at 60 Hz enables reliable startup into large bulk capacitors without fuse tripping
Wide Operating Temperature	–40 °C to +150 °C junction range supports use in enclosed, thermally constrained enclosures
Low Forward Voltage	1.2 V V_FM per diode reduces conduction loss and improves efficiency in 6 A continuous operation
Compact D-72 Package	Standardized footprint allows drop-in replacement across KBPC1/KPBC6 series with identical mounting

Equivalent & Alternatives

Alternative Part	Technical Difference	Application Difference	Selection Advice
KBPC606	Same V_RRM (600 V), same D-72 package, but rated 6 A I_O(AV) - identical electrical and mechanical specification	No functional difference; KBPC606 is Vishay's alternate part number for same device family and rating	Select KBPC606 when sourcing from distributors listing that nomenclature; electrically and physically interchangeable
GBU6K	600 V V_RRM, 6 A I_O(AV), GBU package (larger than D-72); higher I_FSM (150 A), higher V_FM (1.3 V)	Requires PCB layout change due to different outline and lead spacing; better surge tolerance but higher conduction loss	Choose GBU6K only if surge margin >137 A is required and board space permits larger footprint

FAQ

What is the maximum allowable case temperature for continuous operation of VS-KBPC106?

The VS-KBPC106 delivers its full 6.0 A average output current only when the case temperature (T_C) is maintained at 50 °C, as specified in the datasheet's "Forward Conduction" table. At higher case temperatures, output current must be linearly derated per Figure 2 - for example, at T_C = 80 °C, the rated I_O(AV) drops to approximately 4.0 A for resistive/inductive loads. Thermal management must ensure this limit is not exceeded during sustained operation.

Does VS-KBPC106 support capacitive-input filter configurations?

Yes, VS-KBPC106 supports capacitive-input filters but with reduced current rating: 4.7 A I_O(AV) at T_C = 50 °C, versus 6.0 A for resistive/inductive loads. This reflects higher peak currents and increased thermal stress caused by the narrow conduction angle. Designers must verify junction temperature rise using I²t and thermal resistance data, especially when paired with large bulk capacitors.

What is the peak forward voltage of VS-KBPC106 under typical operating conditions?

The VS-KBPC106 exhibits a typical peak forward voltage (V_FM) of 1.2 V per diode at I_FM = 3 A and T_J = 25 °C. Since the bridge contains two diodes conducting in series during each half-cycle, total forward drop is ~2.4 V at 3 A DC output. This value increases with temperature and current - at 6 A and 125 °C, V_FM may reach ~1.5 V per diode.

Can VS-KBPC106 be used in 400 Hz aircraft power systems?

Yes, VS-KBPC106 is rated for operation across 40 to 1000 Hz, explicitly including 400 Hz. Its silicon junction design and thermal construction support stable performance at higher frequencies, though designers must confirm that ripple current and I²t stress remain within limits - particularly since 400 Hz operation reduces time between surges, affecting thermal cycling endurance.

Is VS-KBPC106 RoHS-compliant and halogen-free?

Yes, VS-KBPC106 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard (document 99912). The device uses lead-free matte tin-plated leads and environmentally compliant molding compound, meeting industrial and consumer regulatory requirements without exemptions.
