2KBP01M-E4/51

Overview

The Vishay General Semiconductor - Diodes Division 2KBP01M-E4/51 is a glass passivated single-phase bridge rectifier housed in the KBPM case style. It provides a maximum average forward output rectified current of 2.0 A at an ambient temperature of 55 °C and supports a maximum repetitive peak reverse voltage of 100 V. The device withstands a peak forward surge current of 60 A for a single half-sine wave superimposed on rated load. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at 3.14 A and a maximum DC reverse current of 5 µA at rated DC blocking voltage. The component operates within a junction and storage temperature range of -55 to +165 °C.

• High case dielectric strength provides enhanced insulation and safety margins.
• Epoxy body meets UL 94V-0 flammability rating for improved fire safety.

Applications

• General purpose ac-to-dc bridge full wave rectification
• Switching power supply circuits
• Home appliances control boards
• Office equipment power stages
• Telecommunication applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details, as suffixes indicate delivery modes such as tubes or anti-static PVC trays. Confirm RoHS compliance status with the supplier, noting that historical documentation references Directive 2002/95/EC while current standards align with Directive 2011/65/EU. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Selection Notes

Select this component when a 2 A continuous current rating and 100 V reverse voltage are required for PCB-mounted bridge rectification. Evaluate thermal resistance parameters, specifically the junction-to-ambient and junction-to-lead values, to ensure adequate heat dissipation for the target application environment. Verify that the operating temperature range of -55 °C to +165 °C accommodates the system's extreme environmental conditions without derating the current below the required threshold.

Part Context

This part belongs to the 2KBP series of glass passivated single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series encompasses multiple voltage ratings ranging from 50 V to 1000 V, sharing the standardized KBPM case style. This specific model represents the 100 V variant within the lineup, designed for general-purpose rectification tasks where moderate current handling and compact surface-mount or through-hole integration are necessary.

Replacement Considerations

Cross-reference alternative manufacturers offering equivalent KBPM package bridge rectifiers with matching 2 A current and 100 V voltage ratings. Verify pinout compatibility and physical dimensions to ensure seamless board replacement. Confirm that substitute components meet the same thermal and electrical specifications, particularly regarding surge current capacity and reverse leakage limits.
