The designation SMA150A (often referring to a 150V Transient Voltage Suppressor like the SMAJ150A or related 150V surface-mount diodes) uses the DO-214AC (also known as SMA) package standard. Key Specifications (e.g., SMAJ150A TVS Diode) • Package / Case: DO-214AC (SMA) surface-mount • Type: Transient Voltage Suppressor (TVS) / Zener diode (Unidirectional) • Reverse Standoff Voltage (\(V_{wm}\)): 150 V • Breakdown Voltage (\(V_{br}\)): 167 V (Min) • Clamping Voltage (\(V_{c}\)): 243 V (Max @ \(I_{pp}\)) • Peak Pulse Power: 400 W (10/1000 µs)
