The AVRZ-5 family provides high amplitude outputs (to +500V) with very fast rise times (< 10 ns), very fast fall times (5 or 10 ns), and a pulse width that is variable over a wide range (15 ns to 10 us, or 100 ns to 10 us).
The AVRZ-5A-B has a pulse width range of 100 ns to 10 us, with a maximum duty cycle of 0.1%. The maximum pulse repetition frequency is 5 kHz. The rise time is 5 ns for a 100V pulse, 7.5 ns for a 300V pulse, and 10 ns for a 500V pulse. The fall time is 10 ns.
The AVRZ-5W-B is similar, but it operates at narrower pulse widths (as low as 15 ns) and offers faster fall times of 5 ns. The faster circuitry introduces a small repetitive decaying "back-porch" transient, which is not present in the AVRZ-5A-B model.
