Overview
The Vishay 2KBP005M is a glass-passivated single-phase bridge rectifier in the KBPM case style. It provides a maximum repetitive peak reverse voltage (VRRM) of 50 V and a maximum average forward output rectified current (IF(AV)) of 2.0 A at an ambient temperature of 55 °C. The device supports a peak forward surge current (IFSM) of 60 A for a single half-sine wave superimposed on rated load. Electrical characteristics include a maximum instantaneous forward voltage drop (VF) of 1.1 V per diode at 3.14 A, and a maximum DC reverse current (IR) of 5 µA at 25 °C. The operating junction and storage temperature range extends from -55 °C to +165 °C.
Feature Summary
- Glass passivation provides high case dielectric strength and reliability
- Ideal for printed circuit board mounting with silver-plated leads
- High surge current capability for robust operation
Applications
- AC-to-DC bridge full-wave rectification for switching power supplies
- Home appliances
- Office equipment
- Telecommunication applications
Procurement Notes
Verify component authenticity by checking the manufacturer's document number 88532 and revision date. Confirm compliance with RoHS 2002/95/EC and WEEE 2002/96/EC directives as specified in the datasheet. Ensure the ordering suffix matches the required package code and delivery mode for your specific assembly needs.
Selection Notes
Select this component when a 50 V rating and 2 A continuous current are sufficient for the application. Consider the thermal resistance values (RθJA of 30 °C/W and RθJL of 11 °C/W) for heat dissipation planning. Verify that the PCB copper pad dimensions meet the recommended 12 x 12 mm size for optimal thermal performance.
Part Context
This part belongs to the 2KBP series, which includes variants ranging from 50 V to 1000 V reverse voltage. The 2KBP005M specifically denotes the 50 V version within the KBPM case style family. Equivalent parts in the same series include the 3N253 through 3N259 designations.
Replacement Considerations
Direct substitutes within the same voltage and current ratings include other 2KBP005M units or equivalent 3N253 components from Vishay. Ensure any replacement maintains the KBPM case style and glass passivation characteristics for compatibility.
FAQ
What is the maximum non-repetitive peak forward surge current?
The maximum non-repetitive peak forward surge current (IFSM) is 60 A for a single half-sine wave superimposed on rated load.
What is the typical junction capacitance per diode?
The typical junction capacitance (CJ) is 25 pF, measured at 4.0 V and 1 MHz.
How is polarity indicated on the component?
Polarity is marked on the body of the case, with the positive lead identified by a beveled corner.
