1N4933 Discrete Devices -Diode-Fast Recovery

Product catalog summary

Overview: The document provides technical specifications and characteristics for the 1N4933 to 1N4937 series of fast recovery rectifiers, highlighting their high efficiency, low forward voltage (VF), high current capability, and reliability. These components are designed for high surge current capability and low power loss.

Specifications:

Maximum Ratings: The rectifiers are rated at 25°C ambient temperature, suitable for single-phase, half-wave, 60 Hz resistive or inductive loads. For capacitive loads, current should be derated by 20%.
Voltage Ratings: The series includes various models with different maximum recurrent peak reverse voltages (VRRM), RMS voltages (VRMS), and DC blocking voltages (VDC), ranging from 50V to 600V.
Current Ratings: Maximum average forward rectified current (IF(AV)) is specified, along with peak forward surge current (IFSM) of 30A.
Temperature Range: Operating and storage temperature ranges are from -65°C to +150°C.

Electrical Characteristics:

Maximum Instantaneous Forward Voltage (VF) is 1.2V at 1A.
Maximum DC Reverse Current (IR) is 5µA at 25°C and 150µA at 125°C.
Maximum Reverse Recovery Time (Trr) is 200ns.
Typical Junction Capacitance (Cj) is 10pF.
Typical Thermal Resistance (RθjA) is 65°C/W.

Mechanical Data:

Case: Molded plastic with epoxy rated UL 94V-0 for flame retardance.
Lead: Pure tin plated, lead-free, and solderable per MIL-STD-202, Method 208.
Polarity: Indicated by a color band denoting the cathode end.
Weight: 0.34 grams.

Features:

Green compound indicated by suffix "G" on packing code and prefix "G" on date code.
High temperature soldering guaranteed at 260°C for 10 seconds.

Graphs and Curves:

Maximum Forward Current Derating Curve: Shows the relationship between ambient temperature and average forward current.
Maximum Non-Repetitive Peak Forward Surge Current: Illustrates the peak forward surge current over cycles at 60 Hz.
Typical Reverse Characteristics: Displays instantaneous reverse current against percent of rated peak reverse voltage at various temperatures.
Typical Junction Capacitance: Shows junction capacitance against reverse voltage.
Typical Instantaneous Forward Characteristics: Depicts instantaneous forward current against forward voltage.

Ordering Information: The document provides details on packaging options, including DO-41 packages with various packing codes and configurations, such as AMMO boxes and reels.
