6706A MOSFET — Specifications & Equivalents

About the 6706A

The 6706A is a MOSFET with a drain–source voltage (V_DS) rating of 30 V and a continuous drain current (I_D) of 6.5 A. It can dissipate up to 2 W and is rated to a junction temperature of 150 °C. It is supplied in the SOP8 package.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 30 V
• Max continuous drain current (I_D): 6.5 A
• Power dissipation (P_D): 2 W
• Max junction temperature (T_J): 150 °C
• Package: SOP8

Typical applications

With its 30 V drain–source rating the 6706A sits in the low-voltage class of switching MOSFETs, typically found in 12 V and 24 V automotive and industrial rails, synchronous buck converters, load switching and reverse-polarity protection and H-bridges for small motors.

Gate drive and switching notes

Keep gate–source voltage within the ±20 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Choosing a replacement for the 6706A

A drop-in substitute for the 6706A should match its polarity and offer a drain–source rating of at least 30 V and a continuous drain current rating of at least 6.5 A.

Mechanically, check the replacement against the SOP8 footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.

Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.

Frequently asked questions

What is the 6706A?

The 6706A is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 30 V drain-source and 6.5 A continuous drain current.

What is the maximum voltage of the 6706A?

The 6706A has a maximum drain-source voltage (Vds) of 30 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the 6706A handle?

It is rated for 6.5 A of continuous drain current, with power dissipation limited to 2 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the 6706A come in?

It is listed in SOP8. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the 6706A?

This page lists 17 candidate equivalents matched on electrical ratings and package. Any replacement should meet or exceed the original voltage, current and dissipation figures and use a compatible drive level.
