This document is a datasheet for a series of Schottky barrier diodes (SU1L through SU4L) manufactured by Rectron Inc. Here's a breakdown of the key information:

1. Device Overview:

️· Type: Schottky barrier diodes. These are known for their fast switching speed and low forward voltage drop.
️· Series: SU1L, SU2L, SU3L, SU4L - likely different voltage/current ratings within the series.
️· Applications: Not explicitly stated, but typical applications for Schottky diodes include switching power supplies, freewheeling diodes, and protection circuits.

2. Key Electrical Characteristics (Typical Values - refer to datasheet tables for specific values per part number):

️· Forward Voltage Drop (Vf): Low, making them efficient.
️· Reverse Voltage (Vr): The maximum reverse voltage the diode can withstand. Different part numbers will have different Vr ratings.
️· Forward Current (If): The maximum forward current the diode can handle.
️· Reverse Leakage Current (Ir): The small amount of current that flows in reverse.
️· Reverse Recovery Time (trr): The time it takes for the diode to stop conducting in reverse. Schottky diodes have very fast recovery times.
️· Junction Capacitance (Cj): Important for high-frequency applications.

3. Datasheet Contents:

️· Absolute Maximum Ratings: Maximum voltages, currents, power dissipation, and operating temperature. Exceeding these ratings can damage the device.
