International Rectifier Expands its Portfolio with 200V Ultrafast Recovery Diodes
International Rectifier (IR, El Segundo, CA) announced the expansion of its portfolio of hermetically sealed, high-reliability HEXFRED products to include new 200V ultrafast recovery diodes with soft reverse recovery characteristics. In addition to typical high-reliability space and military applications, the new HFB25xx20, HFB20xx20C, HFB60xx20 and HFB60xx20C diodes may be used in moisture-sensitive undersea fiber optic drivers and telecommunications routers, commercial avionic equipment and oil exploration applications.
The new diodes have current ratings up to 60A and are appropriate for power supplies with input voltages to 100V. With a 200V rating, this diode family is suitable for space and high-reliability design applications with bus voltages up to 100V, where 50-percent de-rating requirements are typically imposed.
The new devices are optimized for key reverse-recovery time performance and reverse-recovery softness. The soft-recovery characteristics eliminate the snubbing circuits in some designs and reduce the size of snubbing components in most design applications. The low forward voltage drop reduces conduction losses and low reverse recovery current reduces power-switching losses.
IR reports that the hermetically sealed ultrafast diodes are available in both single- and common-cathode configurations. Package configurations include TO-254, TO-257, TO-258, and TO-259, as well as surface-mount SMD-0.5, SMD-1, SMD-2, hermetic D2 and D3 packages. The new diodes are available as hermetic commercial off-the-shelf (COTS) as well as screened to space or military QPL equivalent to MIL-PRF-19500 and sold under IR's in-house specifications.
The new diodes are currently available. Pricing begins at $40.96 each in 5,000-unit quantities.
