SSF6670

Overview

The SSF6670 is a dual N-channel MOSFET from Good-Ark Semiconductor, housed in an SOP-8 package. It features a drain-source voltage (Vds) of 60 V and a continuous drain current (Id) of 5 A at 25°C. The maximum on-resistance (Rds(on)) is 90 mΩ at Vgs=10V with Id=5A. Key electrical parameters include a gate threshold voltage (Vgs(th)) ranging from 1.2 V to 2.5 V, total gate charge (Qg) up to 8 nC, and input capacitance (Ciss) up to 540 pF. The device supports a junction temperature range of -55°C to +150°C and offers a power dissipation of 2.5 W.

Feature Summary

• Dual N-channel configuration within a single SOP-8 package for space-efficient designs
• Advanced process technology achieving low on-resistance and high cell density
• Fast switching speed combined with low gate charge for improved efficiency
• Reverse body diode characteristics suitable for synchronous rectification

Applications

• High efficiency switched mode power supplies
• DC-DC converter circuits
• Low voltage battery powered applications

Procurement Notes

Verify the specific manufacturer source when ordering, as component availability may vary across distributors. Confirm the SOP-8 package marking matches 'SSF6670' upon receipt. Ensure thermal management aligns with the specified 60 °C/W junction-to-ambient resistance for continuous operation. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component for applications requiring dual N-channel isolation in a compact surface-mount footprint. The 60 V rating provides adequate headroom for 12 V or 24 V systems. Consider the 90 mΩ Rds(on) limit for conduction loss calculations at full load. The logic-level gate drive capability allows direct interfacing with standard microcontrollers or drivers operating at 3.3 V or 5 V.

Part Context

This part belongs to the category of dual discrete MOSFETs designed for power management. It serves as a compact alternative to using two separate single-channel devices, reducing board space and parasitic inductance. The SOP-8 package facilitates automated assembly while providing sufficient thermal dissipation for moderate current levels typical in consumer electronics and industrial control modules.
