Class D efficiency means the 28-HTSSOP package with its exposed thermal pad can dissipate the heat from a 12W total output without needing a heatsink in many chassis-mount designs, as long as the PCB copper pours under the pad are sized to the datasheet's thermal land pattern. The 4.5V to 14.4V supply range covers single-cell Li-ion (nominal 3.7V boosted to 5V), 5V USB, 9V battery, and 12V automotive electrical systems — the 14.4V upper limit handles a charged lead-acid battery at float voltage without needing an external clamp. ## Protection features that keep the line running Built-in short-circuit protection on the output stage prevents a speaker-wire-to-ground fault from taking out the amplifier — the part shuts down and auto-recovers when the fault clears, which matters for field-replaceable speaker systems where a user might touch bare terminals. Thermal protection throttles or shuts down the output before the die temperature exceeds the silicon limit, so a blocked vent or a high-ambient installation doesn't cause permanent damage — the part comes back when it cools. The depop feature suppresses the power-on thump that would otherwise send a DC transient into the speakers — no external muting relay needed on the output. ROHS3 compliant means it ships without RoHS exemption paperwork, clearing customs globally without additional documentation.","metaTitle":"TPA3137D2PWP Class D Amp, 6W x 2 @ 8Ω, 28-HTSSOP","metaDescription":"Texas Instruments TPA3137D2PWP stereo Class D amp, 6W x 2 into 8Ω, 4.5-14.4V supply, -40 to +85°C, active production, ROHS3.
