ZXMS81045SP-13

Overview

The ZXMS81045SP-13 is a high-side IntelliFET power switch manufactured by Diodes Incorporated. It integrates an N-channel MOSFET with advanced protection features in an 8-SO-EP package. Key electrical parameters include a maximum output current of 4A and a typical on-resistance (Rds(on)) of 34mΩ. The device supports non-inverting input control and operates with fault protection mechanisms including auto-restart capabilities and slew rate controlled switching to minimize electromagnetic interference.

Feature Summary

• Integrates high-side N-channel MOSFET with intelligent protection logic
• Features auto-restart functionality for transient fault recovery
• Includes slew rate control to reduce switching noise and EMI
• Provides comprehensive fault protection against overcurrent and thermal events

Applications

• High-side load switching in automotive systems
• Power distribution units requiring intelligent control
• Industrial equipment load management
• Battery protection circuits in portable devices

Procurement Notes

Verify the specific suffix 'SP-13' matches your required packaging format, as it typically indicates tape and reel quantities. Confirm the 8-SO-EP package dimensions align with your PCB footprint. Ensure the 4A continuous current rating meets your application's peak and steady-state load requirements. Check RoHS compliance status if environmental regulations apply to your final product assembly.

Selection Notes

Select this component when a compact, integrated solution for high-side switching is required. The 34mΩ Rds(on) offers low conduction losses for 4A loads. Consider the auto-restart feature for applications where temporary faults are expected. The non-inverting input simplifies logic interface design compared to active-low alternatives. Evaluate the SO-EP package for thermal performance needs.

Part Context

This part belongs to Diodes Incorporated's IntelliFET family, which combines power MOSFETs with diagnostic and protection circuitry. The ZXMS series is designed for robust performance in demanding environments. The SP-13 designation specifies the standard commercial grade and packaging configuration offered by the manufacturer for general-purpose industrial and automotive applications.

Replacement Considerations

Check for direct pin-compatible substitutes within the same IntelliFET family that offer similar current ratings. Verify that alternative parts support the same 4A output and 34mΩ Rds(on) characteristics. Ensure any replacement maintains the auto-restart and slew rate control features if these are critical to system reliability.
