Product details

What the 25W x 2 @ 4Ω rating means for your BOM

The TPA3123D2PWP is a Class-D stereo amplifier delivering 25W x 2 @ 4Ω. The 10V to 30V supply range covers 12V automotive, 24V industrial, or 28V rails.

Industrial temperature grade and package

Surface-mount only, no through-hole option.

Protection features and shutdown

Built-in short-circuit and thermal protection, plus mute and shutdown pins. The depop feature suppresses turn-on thump — useful if the amplifier powers a speaker that is always connected. These protections mean the part can survive a miswired output or a stalled fan without failing catastrophically, which matters for field-replaceable modules.

Frequently asked questions

What are the alternatives to TPA3123D2PWP?

Within the same TI Class-D family, the TPA3122D2 is a lower-power sibling (15W x 2 @ 4Ω) in the same 24-HTSSOP footprint, but it is not pin-compatible — the pinout differs. For a direct drop-in, stick with the TPA3123D2PWP.
