The VPM2SM uses a 2-pin, side-looking SMD package. Unlike a phototransistor, the photodiode is polarity-sensitive.
Mechanical Outline (Typical per Vishay drawing):
Important: The light-sensitive area is on the side face. The PCB layout must position the device so that the light source is parallel to the board, not perpendicular (as with top-view LEDs). vpm2sm datasheet
While this guide is accurate, always refer to the original manufacturer datasheet for revision changes and lot-specific test data.
The output is tightly regulated, capable of delivering high current with minimal ripple. The VPM2SM uses a 2-pin, side-looking SMD package
According to the VPM2SM datasheet, exceeding any of the following values will permanently damage the component:
Design tip: Always include a series resistor or current-limiting circuit to prevent excessive forward current if the diode is accidentally forward-biased. Mechanical Outline (Typical per Vishay drawing):
Yes. While the peak is at 950nm, the datasheet shows 50% relative sensitivity at 650nm. Use a transimpedance amplifier with high gain to compensate for lower responsivity.
