RMB2S Discrete Devices -Bridge Rectifier-Fast Recovery Bridge

Product catalog summary

Overview: This document provides technical specifications and characteristics for the RMB2S through RMB6S series of miniature glass passivated fast recovery surface mount bridge rectifiers. These components are recognized under UL File # E-326243 and are noted for their high surge current capability and compact size, making them ideal for printed circuit boards.

Mechanical Data: The devices are identified by specific codes such as RMBX for the device code and G for the green compound. The year and work week are also marked. The case is made of molded plastic, and terminals are pure tin plated, lead-free, and solderable per MIL-STD-202, Method 208.

Maximum Ratings and Electrical Characteristics: The ratings are specified at 25℃ ambient temperature unless otherwise noted. The devices are suitable for single-phase, half-wave, 60 Hz resistive or inductive loads, with a 20% current derating for capacitive loads. Key parameters include:

Maximum Repetitive Peak Reverse Voltage (VRRM): 200V to 600V
Maximum RMS Voltage (VRMS): 140V to 420V
Maximum DC Blocking Voltage (VDC): 200V to 600V
Maximum Instantaneous Forward Voltage (VF): 1V at 0.4A
Peak Forward Surge Current (IFSM): 30A
Maximum Average Forward Current (IF(AV)): 0.8A
Maximum Reverse Recovery Time (Trr): 150nS
Typical Junction Capacitance (Cj): 30pF
Typical Thermal Resistance Per Leg (RθjA): 85°C/W

Temperature Ratings: The operating temperature range is from -55°C to +150°C, with a storage temperature range of the same.

Soldering and Construction: High-temperature soldering is guaranteed at 260℃ for 10 seconds with a tension of 5 lbs. (2.3kg). The devices are constructed using a reliable low-cost molded plastic technique.

Compliance: The devices comply with Pb RoHS standards.

Figures and Graphs: The document includes several figures illustrating:

Forward Current Derating Curve
Maximum Non-Repetitive Forward Surge Current Per Leg
Typical Reverse Characteristics Per Leg
Typical Forward Characteristics Per Leg
Typical Junction Capacitance Per Leg

These graphs provide visual data on performance characteristics such as current versus temperature, surge current versus cycles, and voltage versus capacitance.
