Most versions are uni-directional (marked with a cathode band). Check your specific datasheet. For AC lines or bipolar signals, use the “CA” suffix.
Accurate pin identification is critical for preventing prototype oscillations or circuit failure. According to verified technical reviews , the 8-pin layout is typically: Pin Number Description Feedback for voltage regulation 2 Common Ground 3 Current Sense 4 Power Supply Input 5 No Connect (often mislabeled as "EN") 6 Gate Drive Output 7 High-Voltage Startup 8 Voltage Sensing input Applications and Use Cases vpm2sm datasheet
The VPM2SM is suitable for various applications, including: Most versions are uni-directional (marked with a cathode
line or a breakdown of internal voltage loop regulation due to thermal fatigue. Distributed power architectures and sensor modules
Unlike older models like the SDH7711RH, the VPM2SM handles over-voltage protection internally, saving approximately $0.08 per unit in BOM costs.
Distributed power architectures and sensor modules.
