KBL01-E4/51

Overview

The KBL01-E4/51 is a Vishay General Semiconductor single-phase bridge rectifier from the KBPM series. It features a peak repetitive reverse voltage of 100 V and an average forward rectified current of 1.5 A. The device utilizes standard recovery technology with a maximum non-repetitive peak surge current of 30 A. Forward voltage is rated at 1.1 V at 1.5 A, while reverse leakage current is limited to 5 µA at 100 V. It operates within a junction temperature range of -55°C to +150°C and is housed in a 4-SIP (KBPM) through-hole package.

Feature Summary

• Single-phase bridge rectification configuration
• Standard recovery technology for general-purpose applications
• Through-hole mounting via 4-SIP package

Applications

• General-purpose power supply circuits
• DC-AC conversion systems
• Low-voltage rectification modules

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status as indicated by the E4 suffix. Ensure the specific ordering code matches the required package type and electrical ratings before procurement to avoid integration errors.

Selection Notes

Select this component when a 1.5 A current rating and 100 V blocking voltage are sufficient for the design. Consider the thermal management requirements associated with the 4-SIP package. Evaluate if the standard recovery speed meets the switching frequency demands of the target application circuit.

Part Context

This part belongs to the KBPM series of bridge rectifiers manufactured by Vishay. The series offers various voltage and current combinations in a compact through-hole format. The E4 suffix typically denotes lead-free and halogen-free construction compliant with environmental directives.

Replacement Considerations

Direct replacements include other 1.5 A, 100 V bridge rectifiers in the KBPM or similar SIP packages. Verify pinout compatibility and thermal characteristics when substituting with parts from different manufacturers.
