Description

The TB2936HQ is a four-channel BTL power amplifier for car audio applications.
This IC has a pure complementary P-ch and N-ch DMOS output stage, offering maximum output power (POUT MAX) of 49 W. It includes a standby switch, mute function and various
protection features.

BTL stands for “Bridge-Tied Load,” and a BTL power amplifier is a type of audio amplifier configuration used to drive a load, such as a speaker or a transducer, in a way that maximizes power transfer and output without the need for a center-tapped transformer. BTL amplifiers are commonly used in audio applications where increased power output is required, such as in car audio systems and high-power home audio amplifiers.

Description

A965 is 120V, 800mA, PNP Transistor. Complementary to 2SC2235.

PNP transistors comprise the following key components:

PNP transistors control the flow of a large current (collector current) between the emitter and collector using a small current applied to the base (base current). When a base current flows, the PNP transistor permits the flow of electrons from the emitter to the collector, resulting in an increase in collector current. Reducing the base current reduces the collector current. Consequently, PNP transistors are valuable electronic components for controlling large output currents with small input currents.

Absolute maximum ratings ( Ta=25°C )

1. Collector to Base Voltage: Vcbo = – 120 V

2. Collector to Emitter Voltage: Vceo = – 120 V

3. Emitter to Base Voltage: Vebo = – 5 V

4. Collector Current: Ic = – 800 mA

5. Collector Dissipation : Pc = 900 mW

6. Junction Temperature: Tj = 150°C

7. Storage Temperature: Tsg = -55 ~ +150°C
