TLP3052(S,C,F)

TLP3052 is a kind of optoisolators. This device is specifically designed for Triac and SCR application outputs. It consists of a GaA₁₂₋₈₁ photoalbumin and a output circuit in a six-pin Low-profile Dual-in-line Package (DIP).That patented construction realizes high-speed and high-accuracy optical coupling performance. In addition, it also combines a few features such as low-light intensity, good isolation insulation characteristics, long-term stability, and wide frequency response range.

The TLP3052 consists of a LED for the optical input and a triac-driver-output circuit. The triac-driver consists of two field-effect transistors (FETs) as the synchronization circuit driving the triac, as well as two resistors that can be replaced with an optocoupler feedback circuit to improve accuracy and response time. The LED optical radiation is focused by the lens to the detector portion of the optocoupler. When the LED emits current, the detector detects the light intensity and controls the FET drive signal. The FET then activates the triac, which conducts current through the load.

The TLP3052 also features a built-in photoelectric detector, which detects the light intensity emitted by the LED. When the light intensity reaches a certain level, the detector triggers the FET drive circuit and activates the triac driver. This helps to ensure more accurate switching timing and higher accuracy upon controlling the load.

The TLP3052 operates on an input voltage range from 5 to 24 V, with minimum saturation voltage of 4 V. The maximum FEET voltage is \-20 V and the detector can switch the input current with a maximum output current of 50 mA. It offers a wide frequency range (100 Hz~200 kHz) and a wide operating temperature range (-55°C to 105°C).

In conclusion, the TLP3052 is an optoisolator that is specifically designed for Triac and SCR application outputs. It is a low-profile, dual-in-line package consisting of a GaA₁₂₋₈₁ photoalbumin and a output circuit. It features high-speed, wide frequency response, long-term stability, excellent isolation insulation characteristics, and low-light intensity. It also features a photoelectric detector, which helps to ensure more accurate switching timing and higher accuracy upon controlling the load.
