Overview
The KBJA1510-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features glass passivation and operates within a junction temperature range of -55°C to +150°C. The device provides a maximum recurrent peak reverse voltage of 1000V, with a corresponding maximum RMS voltage of 700V and DC blocking voltage of 1000V. It supports an average forward current of 15A at a case temperature of 100°C with a heatsink, or 3.2A at 25°C ambient without a heatsink. Key electrical parameters include a maximum instantaneous forward voltage of 1.0V, a peak forward surge current of 220A for an 8.3ms half sine-wave, and a maximum DC reverse current of 150μA at 125°C.
Feature Summary
- Glass passivation protects the junction against mechanical stress and improves stability during soldering.
- High surge forward current capability allows handling of transient load conditions.
- Epoxy material meets UL 94 V-0 flammability rating for enhanced safety.
Applications
- AC to DC power supply circuits requiring high voltage isolation.
- Battery charging systems operating with standard mains input.
- General purpose rectification in industrial equipment.
Procurement Notes
Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm the specific suffix indicates RoHS compliance and lead-free finish. Ensure storage conditions align with the specified temperature ranges to maintain component integrity prior to assembly.
Selection Notes
Select this component when a 1000V reverse voltage rating is required for single-phase applications. Evaluate thermal management needs carefully, as the average forward current drops significantly from 15A to 3.2A when operating without a heatsink compared to operation at 100°C case temperature with a heatsink.
Part Context
This part belongs to the KBJA1506 through KBJA1510 series, sharing identical mechanical dimensions and thermal characteristics while varying only in voltage ratings. The KBJA1510 represents the highest voltage variant in this specific lineup, designed for demanding high-voltage rectification tasks.
Replacement Considerations
Compatible substitutes within the same series include KBJA1506 and KBJA1508, provided the circuit voltage requirements do not exceed their respective 600V and 800V ratings. Other manufacturers offering equivalent JB package bridge rectifiers with matching 15A current and 1000V voltage ratings may also serve as functional replacements.
FAQ
What is the maximum non-repetitive peak forward surge current?
The maximum non-repetitive peak forward surge current is 220A for an 8.3ms half sine-wave.
How does the average forward current change based on cooling conditions?
The average forward current is rated at 15A when mounted on a heatsink at a case temperature of 100°C, but reduces to 3.2A at 25°C ambient temperature without a heatsink.
What is the dielectric strength of the device?
The dielectric strength is 2KV between terminals and case for one minute at AC.
