STA50013TR - 60W Stereo Class D Amplifier | STMicroelectronics
MPN: STA50013TR ✗ اختتامِ زندگیSTA50013TR جائزہ
A Class D amplifier is a switching power amplifier that uses pulse-width modulation to drive output transistors continuously. Compared with a linear audio amplifier, this architecture can provide high output power with lower conduction losses because the internal MOSFETs spend most of their time in low-resistance switching states. In this device, the quad half-bridge arrangement allows one package to support multiple speaker channels in audio systems, automotive equipment, and powered speaker designs.
Key features include 60 W output power per channel into an 8-ohm load, operation from 10 V to 36 V, and complementary DMOS output stages with an on-resistance of 200 mOhm. The output stage includes thermal protection and thermal warning functions, while output overvoltage and undervoltage protection help prevent operation outside the intended output conditions. CMOS-compatible logic inputs simplify connection to a system controller or audio processor.
The STA50013TR combines four configurable half bridges rather than integrating a conventional analog voltage amplifier and output stage in each channel. This makes it suitable for bridge-tied speaker loads, where each speaker is driven differentially. The 200 mOhm complementary DMOS output stage is the central switching element, while the BCDMOS process supports the combination of high-voltage handling, logic functions, and power output transistors in one integrated circuit.
Typical uses include car-audio and automotive audio amplification, powered speakers, home-audio systems, portable installations, and industrial sound equipment. The quad configuration can also be arranged as four independent channels or combined into two stereo channels. Thermal design, speaker impedance, supply capability, and output filtering remain important because the amplifier dissipates substantial power during high-level operation and switching edges can generate high-frequency electromagnetic energy.
For a new design, confirm the complete pin configuration in the manufacturer datasheet, follow the recommended input, supply, and output-filter networks, and place the exposed thermal area over an uninterrupted copper region. Because the device is listed as obsolete by one technical source while distributor inventory is also shown, verify current assembly life-cycle status before committing a new production design. A currently supported product should be selected for new production when possible.
This page summarizes the principal electrical ratings, protection functions, package characteristics, and application considerations of the STA50013TR. It also documents the practical absence of a confirmed pin-to-pin drop-in substitute, helping engineers compare this part against newly proposed amplifier ICs without assuming that a similar wattage rating guarantees PCB compatibility.

Automotive Audio Power Stage
The STA50013TR is suitable for a 12 V automotive audio architecture when its four half bridges are assigned to two stereo channels. Each stereo channel is rated for 60 W into an 8-ohm load, while the 10 V to 36 V supply range accommodates battery-fed systems with regulated headroom. The internal short-circuit, thermal, output overvoltage, and output undervoltage protections support robust speaker-drive behavior. However, the listed 0 C to 70 C operating range and obsolete lifecycle status require careful review for a new vehicle program.

Powered Stereo Speaker
The STA50013TR can form the output stage of a powered stereo speaker because two bridge-tied half bridges can drive each 8-ohm channel at up to 60 W. This arrangement reduces the number of packages needed for a conventional two-channel speaker amplifier while providing integrated output protection. The design must use the manufacturer-recommended PWM filter and power-supply layout, and it must verify continuous output, thermal rise, and enclosure airflow rather than relying only on the headline power rating.
تجویز کردہ
Four-Channel Distributed Audio
For distributed audio, the four internal half bridges allow the STA50013TR to implement a four-channel output arrangement instead of a two-channel stereo configuration. Each bridge-tied output can feed a separate speaker section, making the device useful in multi-zone sound equipment where each channel operates at a lower power level. Designers should confirm the recommended mode-control connections, filter topology, and channel-power limits in the manufacturer datasheet before assigning the four outputs to separate loads.

Professional Audio Amplifier
The STA50013TR's 60 W x 2 stereo capability suits compact professional and installed-audio amplifier modules requiring high output power from a surface-mount IC. Its complementary DMOS output stage and integrated thermal and short-circuit protection simplify the power-output section. Real products should include input conditioning, the prescribed PWM reconstruction filter, robust supply decoupling, and a thermal design based on actual music waveform and speaker load. The obsolete status makes it more appropriate for established equipment than for a newly launched product.

Industrial Sound Reinforcement
A compact industrial sound amplifier can use two half bridges as a bridge-tied stereo output or distribute the four bridges across separate speaker zones. The STA50013TR operates from a 10 V to 36 V supply, allowing implementation from an industrial DC rail with appropriate regulation. Integrated short-circuit and thermal protection improves robustness, while output overvoltage and undervoltage protection helps manage abnormal speaker conditions. EMI control remains critical because the switching outputs require careful filtering and layout isolation from sensitive analog inputs.

Legacy Audio Equipment Repair
The STA50013TR is most practical for repairing or maintaining an amplifier board that already uses its 36-pin PowerSO-36 footprint and established control topology. Exact pin continuity, output-filter component values, supply requirements, and thermal conditions must match the original design; a device with similar electrical ratings alone is not sufficient. Because this part is marked obsolete, buyers should request current original inventory, traceability details, and inspection information through the quote form before using it for service or production continuity.

ڈیزائن نوٹس
Treat the exposed underside of the PowerSO-36 package as the primary heat path. Place it over a continuous copper region with minimal interruption across board layers, add thermal vias where the manufacturer's layout permits, and avoid enclosing the amplifier without an intentional airflow path. A thermal assessment should include maximum continuous output, speaker resistance, signal crest factor, ambient temperature, and enclosure temperature because music peaks can create substantially greater average loss than sine-wave testing.
Separate the four switching outputs from sensitive input and control traces, and use the shortest practical connection to the output-filter components. Keep the high-current supply loop compact and provide local ceramic decoupling where the datasheet recommends it. Do not route output traces beneath analog input, microphone, or control circuitry without considering the switching edge current and electromagnetic coupling paths.
The STA50013TR is rated for 60 W x 2 at 8 ohms, so the supply wiring, protection devices, connectors, and copper areas must support the corresponding load current without excessive voltage drop. Use the manufacturer power-supply and decoupling layout as the baseline. When reusing the circuit in a different topology, recalculate output-device dissipation and thermal rise for the actual speaker impedance and duty cycle instead of assuming that the stereo rating applies to every half-bridge configuration.
Do not substitute a Class D amplifier solely because its advertised wattage matches 60 W. Confirm the PowerSO-36 footprint, every pin assignment, mode-control logic, output-filter design, supply range, output-current capability, and protection behavior. Also check the operating-temperature grade and lifecycle status. A cross-compatible footprint with different control or output definitions can damage the PCB or cause unintended bridge operation.
