• Fast switching speed optimized for high-frequency circuit operation

Applications

• Battery-operated system power management
• General-purpose load switching
• Driver circuits for lamps, relays, and displays

Procurement Notes

Verify the specific datasheet version from Comchip Technology or authorized distributors to confirm exact electrical tolerances and marking codes. Ensure the SOT-363 package dimensions match the target PCB layout requirements. Confirm RoHS compliance status with the supplier documentation prior to final procurement decisions.

Selection Notes

Select this component when space-constrained designs require two N-channel switches. Compare total on-resistance values against standard single-channel alternatives to evaluate efficiency gains. Consider the 60V breakdown voltage limit for appropriate circuit voltage headroom. Verify thermal dissipation capabilities relative to the expected duty cycle and ambient temperature conditions.

Part Context

This part belongs to the 2N7002 family of dual N-channel MOSFETs. While standard 2N7002 devices are typically single-channel, the KDW suffix denotes the dual-channel variant in the SOT-363 package. This configuration allows for cost and board area reduction in applications requiring multiple switching elements compared to using discrete single-channel components.

Replacement Considerations

Direct substitutes include other manufacturers' 2N7002KDW variants such as those from HY Electronic Corp or Jiangsu Changjiang Electronics. Verify pinout compatibility and electrical parameter equivalence before substitution.
