Product details

Active production — still a current BOM line

The TDA7265B: ROHS3 compliance is confirmed, covering the current EU exemption scope for lead in solder and other restricted substances.

30 W per channel into 8 Ω — the headline output rating

Rated 30 W per channel into an 8 Ω load, the TDA7265B drives a stereo pair of 8-ohm speakers to that level continuously — the limiting factor is the thermal dissipation in the Multiwatt-11 package, not the output stage itself. The supply range spans ±8 V to ±33 V, accommodating both single-rail and split-rail topologies; the designer picks the rail voltage that matches the target output power and speaker impedance. Built-in depop, mute, short-circuit and thermal protection, and standby reduce the external BOM count — no separate muting relay or protection controller needed for a self-contained amplifier stage.

Multiwatt-11 through-hole — footprint and integration

Operating temperature range is -20°C to 85°C ambient — this is a commercial/industrial grade, not automotive; the part suits consumer audio, powered speakers, and industrial audio signalling where the enclosure stays above freezing.

Pin-to-pin with TDA7265A — the 25 W sibling

The TDA7265A and TDA7265 share the same Multiwatt-11 package, same feature set (depop, mute, protection, standby), and same supply voltage range — the only parametric difference is the output power: 25 W per channel at 8 Ω vs the TDA7265B's 30 W. A board laid out for the TDA7265A accepts the TDA7265B without a PCB spin — the pinout and footprint are identical; the higher output power simply requires adequate heatsinking to keep the junction below the 85°C ambient ceiling.

Frequently asked questions

What is the closest functional second-source to the TDA7265B?

The TDA7265A and TDA7265 are the closest peers — same package (Multiwatt-11), same feature set, same supply range. The difference is output power: 25 W at 8 Ω vs the TDA7265B's 30 W. They are pin-to-pin compatible, so a board designed for one accepts the other without layout changes.

What compliance documentation does STMicroelectronics provide for the TDA7265B?

The TDA7265B is ROHS3 compliant per the current EU RoHS exemption scope. STMicroelectronics provides the standard declaration of conformity and material declaration upon request through the supply chain.
