2KBP02M-E4/51

Overview

The Vishay General Semiconductor - Diodes Division 2KBP02M-E4/51 is a glass passivated single-phase bridge rectifier utilizing 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 200 V. The component features a peak forward surge current capability 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 per diode at 3.14 A, a maximum DC reverse current of 5 µA at 25 °C, and a typical junction capacitance of 25 pF at 4.0 V and 1 MHz. The device operates within a junction and storage temperature range of -55 to +165 °C.

Procurement Notes

Verify the specific ordering suffix to confirm the delivery mode and package quantity. The /51 suffix indicates an anti-static PVC tray containing 600 units per base quantity. Confirm RoHS compliance status as defined by Directive 2011/65/EU during procurement to ensure alignment with environmental regulations. Cross-reference the manufacturer part number with distributor databases to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when a 200 V peak reverse voltage rating is required alongside a 2 A continuous forward current capacity. Ensure the application environment allows for thermal management compatible with the specified operating junction temperature range up to 165 °C. Verify that the PCB layout accommodates the KBPM through-hole package dimensions and terminal spacing. Consider the 60 A non-repetitive surge current rating to ensure adequate protection against transient load conditions.

Part Context

This component belongs to the 2KBP series of glass passivated single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series encompasses various voltage ratings ranging from 50 V to 1000 V, sharing common mechanical and electrical characteristics such as the KBPM case style and silver-plated leads. The 2KBP02M variant specifically addresses designs requiring a 200 V blocking voltage threshold.

Replacement Considerations

Compatible substitutes within the same datasheet include the 3N255 model, which shares identical electrical ratings and physical dimensions. Other models in the 2KBP series may serve as alternatives if voltage or current requirements differ, provided the KBPM package footprint remains consistent.
