Vpm2sm Datasheet -
Before diving into pin configurations, let’s review the hallmark features that define this component:
| Parameter | Value/Description | | :--- | :--- | | Package Type | SMD (Surface Mount Device) – Side-looking, gull-wing leads | | Diode Type | PIN Photodiode | | Spectral Range | 350 nm to 1100 nm | | Peak Wavelength | 950 nm (Near Infrared) | | Active Area | 7.5 mm² (typical) | | High Photosensitivity | 0.55 A/W @ 950 nm (typical) | | Rise/Fall Time | 100 ns (typical, at 5V reverse bias) | | Dark Current | 5 nA max (at 10V reverse bias) | | Temperature Range | -40°C to +100°C (operating) |
These specifications confirm the VPM2SM is ideal for high-speed data links, optical encoders, and infrared remote control systems. vpm2sm datasheet

The output is tightly regulated, capable of delivering high current with minimal ripple. Before diving into pin configurations, let’s review the
The module provides galvanic isolation between the high-voltage input and the low-voltage output. The VPM2SM typically offers 1500VDC to 3000VDC isolation, making it suitable for applications requiring safety isolation or level shifting.
Scenario: An industrial PLC (Programmable Logic Controller) requires a 24V DC rail for I/O modules. The facility utilizes a 380VDC bus distribution system. | Parameter | Symbol | Value | Unit
Implementation:
In sealed environments, the baseplate must be attached to a heatsink or chassis. Thermal interface material (TIM) with high thermal conductivity (e.g., 1.0 W/m-K or higher) is required between the module and the mounting surface.
Note on Variants: The suffix "SM" in VPM2SM typically refers to the package style and pin configuration (Surface Mount or Through-Hole with Standoffs). Engineers should verify the pinout diagram in the specific datasheet to ensure PCB layout compatibility.
A: Not typically. For pure overvoltage protection, it is placed directly in parallel with the load. However, for very high-energy surges (>600W), add a PTC or fuse in series.
