Audio Amplifier Tda3653c

The TDA3653C is a legacy semiconductor component that is primarily categorized as a vertical deflection output circuit, rather than a standard audio amplifier Datasheet4URfparts. It was originally designed to drive deflection systems in 90° color picture tubes (CRTs) Mouser.

Product Insights & Specifications

* True Function: While often mislabeled in hobbyist searches as an audio amplifier, it is technically a vertical deflection booster Radio18. It includes a driver, output stage, flyback generator, and protective guard circuits to prevent screen damage Alldatasheet.

* Key Specs: Operates on a supply voltage of 10V to 40V, providing a peak-to-peak output current of up to 1.5A Datasheet4UDigchip.

* Package Type: Housed in a 9-lead Single In-Line (SIL) plastic power package (SOT131) Mouser.

Market Trends & Availability

* Obsolescence: The TDA3653C is currently classified as Obsolete/End-of-Life (EOL) Dasenic. It is no longer in active production by its original manufacturer, Philips (now NXP) Componentsense.

* Sourcing Difficulty: Bulk sourcing via major B2B platforms like Alibaba is limited, with most results showing similar but different models such as the TDA3653B or TDA8172 .

* Secondary Market: Availability is now restricted to New Old Stock (NOS) specialty vendors and independent distributors, where units are priced around $4.90 GoogleRfparts.

* Trend Outlook (2026): For industrial or repair needs, the market is shifting toward component harvesting or identifying pin-compatible modern deflection boosters, as legacy inventories for CRT-era components continue to deplete Procurementpro.
