Electrical & Optical Characteristics (Typical @ 25°C)
The core of any VPM2SM datasheet is the electrical table. Below are the key parameters for circuit design:
| Symbol | Parameter | Test Condition | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | IP | Photocurrent | Ee = 1 mW/cm², λ = 950 nm, VR=5V | 16 | 24 | 32 | µA | | λ0.5 | Spectral Range | Sensitivity > 50% of peak | 350 | - | 1100 | nm | | VR | Reverse Voltage | IR = 100 nA | 60 | - | - | V | | ID | Dark Current | VR = 10 V, E=0 | - | 2 | 5 | nA | | CD | Junction Capacitance | VR = 5 V, f = 1 MHz | - | 32 | - | pF | | tr / tf | Rise/Fall Times | VR = 5 V, RL=50Ω, λ=950nm | - | 100 | - | ns |
Analysis: The low dark current (2nA typical) ensures high signal-to-noise ratio in low-light applications. The 32pF capacitance combined with 100ns switching speed suggests a maximum data rate of approximately 3.5 Mbps in a standard transimpedance amplifier configuration.
Part 5: Interpreting the VPM2SM Datasheet Graphs
PDF datasheets often contain crucial performance curves. Here’s how to read them for the VPM2SM:
Thermal and mechanical
- Thermal resistance junction-to-ambient (θJA) depends on package and PCB layout; estimate 45–60 °C/W for a typical small QFN on a 2-layer board with standard copper.
- Power dissipation is low (primarily quiescent), but ensure thermal vias under package center pad if continuous higher currents are present on driven outputs.
- Package dimensions: Example 12-pin UDFN 2.0 mm × 2.0 mm, 0.4 mm pitch; actual mechanical drawings and recommended land patterns must be taken from the manufacturer.
