PT76S16 — 3 Phase Bridge Diode Module (75 A, 1600 V)
The PT76S16 is a rugged three-phase bridge diode module engineered for high-power industrial use, delivering reliable rectification where performance matters. Rated for an average rectified output current of 75 A and a repetitive peak reverse voltage of 1600 V, the PT76S16 gives designers a compact, high-voltage solution for converting AC to DC in demanding environments. Its low forward drop (typical peak forward voltage 1.4 V at 75 A) and high non-repetitive surge capability make it well suited for continuous heavy loads and transient events commonly seen in motor drives, inverters and UPS systems.
Built for durability and stable thermal operation, the PT76S16 features an isolated base, UL recognition and a low junction-to-case thermal resistance (0.24 °C/W), enabling efficient heat transfer and simplified cooling design. The module supports a wide junction temperature range (-40 °C to +125 °C) and offers strong insulation (terminal-to-base AC 2500 V, 1 minute). Mechanical installation is straightforward with M5 mounting (recommended torque 2.4–2.8 N·m) and a compact footprint (approx. 180 g), which together reduce assembly time and help keep system size down. These characteristics improve uptime and lower lifecycle costs in industrial and commercial power electronics.
Because it is a purpose-designed rectifier module, the PT76S16 integrates easily into three-phase power conversion chains and is commonly used in motor controllers, industrial drives, battery chargers, and power supplies where reliability and surge performance are essential. Engineers choosing the PT76S16 gain a proven, high-voltage diode bridge that balances efficiency, thermal performance and mechanical robustness — a practical choice when upgrading legacy rectifiers or designing new high-power systems for continuous operation.
