ECH8657-TL-H

Overview

The onsemi ECH8657-TL-H is a dual N-channel enhancement mode MOSFET array housed in an 8-ECH surface-mount package. It features a maximum drain-source voltage of 35 V and a continuous drain current of 4.5 A at 25°C. The device exhibits a maximum on-resistance of 59 mΩ at 2 A with a 10 V gate drive, alongside a typical gate charge of 4.5 nC at 10 V. Designed for high thermal performance, it supports a maximum power dissipation of 1.5 W and operates up to a junction temperature of +150 °C.

Feature Summary

• Dual N-channel configuration within a compact 8-pin ECH footprint
• Logic-level gate operation enabling direct interface with standard logic drivers
• High-temperature capability supporting reliable operation up to +150 °C

Applications

• Automotive anti-lock braking systems (ABS)
• Industrial motor control circuits
• Power management modules requiring low-voltage switching

Procurement Notes

Verify the specific suffix against official datasheets to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the ordering quantity aligns with manufacturer minimum order requirements for the selected packaging variant.

Selection Notes

Select this component for applications requiring dual N-channel isolation in a small outline package. Evaluate the 59 mΩ on-resistance against load current requirements to ensure thermal limits are not exceeded. Verify that the 35 V breakdown voltage provides adequate margin for the target circuit supply rails.
