2KBP005M

Bridge Rectifier Overview

The onsemi 2KBP005M is a single-phase bridge rectifier utilizing glass-passivated silicon die within a KBPM molded plastic package. It provides an average forward current of 2.0 A at 50°C and withstands a maximum repetitive peak reverse voltage of 50 V. The device features a non-repetitive peak forward surge current rating of 60 A for 8.3 ms half-sine-wave pulses. Electrical characteristics include a forward voltage drop of 1.1 V per element at 3.14 A and a reverse leakage current of 5 µA at 25°C. Thermal management relies on a junction-to-ambient thermal resistance of 18 °C/W per leg, supporting operation across a temperature range from -55°C to +150°C.

Bridge Rectifier Feature Summary

• Glass-passivated construction ensures reliable low-cost performance with UL certification.
• High surge overload capability rated at 60 amperes peak for transient protection.

Bridge Rectifier Procurement Notes

Verify the manufacturer origin carefully, as Fairchild Semiconductor was acquired by onsemi. Confirm that the component matches the specific electrical ratings and physical dimensions required for your design. Check for updated datasheets reflecting any post-acquisition manufacturing changes or packaging updates. Ensure compliance with RoHS directives if applicable to your region.

Bridge Rectifier Selection Notes

Select this component when a 50 V peak reverse voltage rating is sufficient for the application's input waveform. The 2.0 A average current capacity suits moderate load requirements. Consider the KBPM through-hole package constraints during PCB layout. Evaluate thermal dissipation needs based on the specified junction-to-ambient resistance under expected operating conditions.

Bridge Rectifier Part Context

This part belongs to the 2KBP series of bridge rectifiers, which covers a voltage range from 50 V to 1000 V. The 2KBP005M specifically addresses the lowest voltage tier in this lineup. It shares the same physical footprint and current handling capabilities as higher voltage variants like the 2KBP100M, allowing for potential design flexibility regarding voltage headroom.

Bridge Rectifier Replacement Considerations

Direct pin-compatible replacements include the Vishay 3N253. Verify that substitute components maintain identical forward voltage and reverse leakage specifications to ensure circuit performance consistency.

Bridge Rectifier FAQ

What is the maximum RMS bridge input voltage?

The maximum RMS bridge input voltage is 35 V.

How does the reverse current change at high temperatures?

The reverse current increases significantly at elevated temperatures, reaching 500 µA at 125°C compared to 5 µA at 25°C.

Is the device suitable for capacitive loads?

The datasheet specifies ratings for resistive or inductive loads. For capacitive loads, the average forward current should be derated by 20%.
