The provided information introduces two families of high-power rectifier diodes manufactured by ABB: standard rectifier diodes and avalanche diodes. Here are key points from the passage:

1. Two Families of High-Power Rectifier Diodes:
   • ABB offers two families of high-power rectifier diodes: standard rectifier diodes and avalanche diodes.
2. Outstanding Reliability and Current Capabilities:
   • Both families of diodes are well-known for their outstanding reliability and excellent nominal and surge current capabilities.
3. Standard Rectifier Diodes:
   • Optimized for line frequency and low on-state losses.
   • Main applications include rectifiers for large AC drives, aluminum smelting, other metal refining, and trackside supply.
   • Available for safe and easy parallel or series connection in groups with similar VF (forward voltage) characteristics.
4. Avalanche Diodes:
   • Self-protected against transient overvoltages.
   • Offer reduced snubber requirements.
   • Feature maximum avalanche power dissipation.
   • Frequently used for input rectifiers in traction converters or high-voltage power rectifiers.
   • Available for safe and easy parallel or series connection in groups with similar Qrr (reverse recovery charge) characteristics.
5. Product Specifications (Standard Recovery Diodes):
   • Various standard recovery diode models are listed with specifications including part number, voltage ratings (VRSM, VRRM), current ratings (IFAVM), surge current capability (IFSM), forward voltage drop (VT0), reverse recovery time (rT), thermal resistance (RthJC and RthCH), mechanical properties (Fm and Housing), and more.
6. Housing Types:
   • Different diode models are housed in specific types, such as H2, L1, N, Q, T1, D, F.
7. Application Note:
   • The passage mentions the availability of an ABB application note titled “Applying fast recovery diodes” for additional recommendations and guidance.
8. Parallel or Series Connection:
   • Both types of diodes are designed for safe and easy parallel or series connection.

The passage provides a detailed overview of ABB’s high-power rectifier diodes, highlighting their applications, characteristics, and specifications, including those for standard rectifier diodes and avalanche diodes.
