2KBP10M-E4/51

Overview

The Vishay General Semiconductor 2KBP10M-E4/51 is a glass passivated single-phase bridge rectifier 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 1000 V. The device handles 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, a maximum DC reverse current of 5 µA at rated DC blocking voltage (25 °C), and a typical junction capacitance of 25 pF per diode at 4.0 V and 1 MHz. The operating junction and storage temperature range spans from -55 to +165 °C.

• Telecommunication applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging details. The /51 designation corresponds to anti-static PVC tray delivery with a base quantity of 600 units. Confirm that the component meets RoHS 2002/95/EC and WEEE 2002/96/EC directives as stated in the datasheet. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the Vishay manufactured part.

Selection Notes

Select this component when a 2 A continuous current rating and 1000 V reverse voltage are required for PCB mounting. The KBPM package offers a compact form factor suitable for space-constrained designs. Verify thermal management requirements, as the maximum average forward current derates significantly above 55 °C ambient temperature. Consider the 60 A surge capability for applications involving high inrush currents or capacitive loads.

Part Context

This component belongs to the 2KBP series of glass passivated single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants ranging from 50 V to 1000 V reverse voltage ratings, all sharing the same KBPM case style and 2 A current capacity. The 2KBP10M specifically denotes the 1000 V variant within this lineup, designed for general-purpose rectification tasks in consumer and industrial electronics.

Replacement Considerations

Cross-reference with other Vishay parts in the 2KBP series for different voltage ratings if system requirements change. Verify pinout compatibility and physical dimensions when substituting with components from other manufacturers. Ensure replacement parts meet the same thermal resistance and surge current specifications to maintain circuit integrity.

FAQ

What is the maximum non-repetitive peak forward surge current?

The maximum non-repetitive peak forward surge current is 60 A for a single half-sine wave superimposed on rated load.

How does the average forward current change with ambient temperature?

The maximum average forward output rectified current is rated at 2.0 A at an ambient temperature of 55 °C. The current must be derated for operation at higher ambient temperatures as shown in the derating curve.
