Product type | IC(ON) (mA) min | Test Conditions | Output | Aperture Width (mm) |
H21B1 | 7.5 | If=10mA, VCE = 1.5V | Photodarlington | 0.94 |
H21B2 | 14.0 | If=10mA, VCE = 1.5V | Photodarlington | 0.94 |
H21B3 | 25.0 | If=10mA, VCE = 1.5V | Photodarlington | 0.94 |
The H21BX products consist of a infrared light emitting diode coupled to an NPN silicon photodarlington packaged in a injection molded housing. The package is designed to optimize the mechanical resolution, coupling efficiency, ambient light rejection, and reliability. Inserting/removing an opaque material into the gap when the LED is operating, switches the darlington on/off.
