A> Switching speed is affected by the RC time constant formed by the phototransistor's junction capacitance and the load resistance (R_L). A smaller R_L(like 100Ω) gives a faster time constant, allowing measurement of the intrinsic speed of the device. In a real application with a larger R_Lfor higher voltage swing, the switching speed will be slower.

. Operational Principle

The ITR20001/T operates on the principle of modulated light reflection. The internal infrared LED emits light at 940nm. The phototransistor, which is sensitive to this wavelength, is positioned such that it does not directly "see" the LED's light beam under normal conditions (no object present). Its output remains in a high-impedance/low-current state (dark current). When a reflective object enters the predefined gap between the emitter and detector, it reflects a portion of the infrared light onto the phototransistor's active area. This incident light generates base current in the phototransistor, causing it to turn on and conduct a significantly higher collector current (I_C(ON)). This change in current/voltage at the output pins is detected by the external circuit, signaling the presence of the object.
