Here's a breakdown of the provided text, summarizing the key information about the SR1A through SR1M rectifier diodes.

1. Overview:

️· Type: Rectifier diodes
️· Series: SR1A through SR1M (multiple variations within the series)
️· Key Feature: Designed for surface mount applications.

2. Electrical Characteristics (Typical Values - see table for full range)

️· Repetitive Peak Reverse Voltage (Vrrm): 50V to 1000V (depending on the specific SR1x model)
️· RMS Voltage (Vrms): 35V to 700V (depending on model)
️· DC Blocking Voltage (Vdc): 50V to 1000V
️· Average Forward Current (If(av)): 1.0A for all models.
️· Peak Forward Surge Current (Ifsm): 30.0A for all models.
️· Forward Voltage (Vf): 1.3V at 1.0A.
️· Reverse Leakage Current (Ir): Low, with specified values at different temperatures (5.0μA to 100.0μA)
️· Reverse Recovery Time (Trr): 150ns (some models have 500ns).
️· Capacitance (Cj): 8.5pF.

3. Thermal Characteristics:

️· Thermal Resistance (R(-)JA): 85.0°C/W
️· Thermal Resistance (R(-)JL): 28.0°C/W
️· Operating Junction Temperature: -65°C to +175°C

4. Important Notes:

️· The "Reverse Recovery Condition" refers to a specific test setup to measure reverse recovery time: If = 0.5A, Ir = 1.0A, Irr = 0.25A.
️· The capacitance is measured at 1.0 MHz with a 4.0V applied voltage.
️· The thermal resistance values apply when the diode is mounted on a PCB with a 0.2x0.2 inch (5.0x5.0mm) copper pad.
