KBP307G C2

Overview

The Taiwan Semiconductor KBP307G C2 is a glass-passivated single-phase bridge rectifier designed for printed circuit board mounting. It features a molded plastic body with matte tin-plated leads and green compound molding. The component supports a maximum average forward rectified current of 3A and offers a voltage range from 50V to 1000V, with the 307 variant rated at 1000V peak repetitive reverse voltage. Key electrical parameters include a typical junction capacitance of 215pF per leg, a maximum instantaneous forward voltage of 1.1V at 3A, and a peak forward surge current capability of 80A (8.3ms). It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivation provides stable electrical characteristics and low leakage current.
• Molded plastic case meets UL flammability classification rating 94V-0.
• Matte tin plated leads ensure solderability in accordance with JESD22-B102 standards.
• Halogen-free construction complies with IEC 61249-2-21 definitions.

Applications

• General purpose AC to DC conversion in power supply circuits.
• Printed circuit board mounting for compact electronic devices.
• High surge current applications requiring robust rectification capabilities.

Procurement Notes

Verify that the ordering suffix 'C2' corresponds to the specific packing code defined in the official datasheet. Confirm the presence of the 'G' suffix indicates halogen-free material compliance. Ensure the procurement documentation matches the exact part number KBP307G C2 to guarantee correct voltage ratings and mechanical specifications.

Selection Notes

Select this component when a 3A continuous current rating and 1000V reverse voltage are required for PCB-mounted applications. Consider the thermal resistance values and derating curves for high ambient temperature environments. Verify compatibility with lead-free soldering processes due to the matte tin plating and RoHS directive compliance.

Part Context

This component belongs to the KBP301G through KBP307G series of glass-passivated single-phase bridge rectifiers manufactured by Taiwan Semiconductor. The series shares a common KBP package outline and general electrical architecture, differentiated primarily by their maximum repetitive peak reverse voltage ratings ranging from 50V to 1000V.

Replacement Considerations

Compatible substitutes include other KBP307 variants from different manufacturers, such as those from Microdiode or Nanjing International Group, provided they meet the same 3A current and 1000V voltage ratings. Ensure any replacement maintains the KBP package dimensions and polarity marking conventions.
