Picotest J2200A - Optocoupler CTR Measurement Module

Overview

The Picotest J2200A Optocoupler CTR Measurement Module is an indispensable tool for professional design engineers seeking precision in their circuit design. This instrument simplifies the measurement of key parameters such as Current Transfer Ratio (CTR), ΔCTR, V_F, and ΔRd for optocouplers. It supports various bias conditions and offers pulse current mode measurement to reduce temperature rise during testing, thereby improving measurement accuracy.

Optocouplers, crucial for isolation feedback control circuits, have varying CTR ranks from 50% to 600%. The J2200A instrument can measure both AC and DC parameters, which are not typically provided by manufacturers. This makes it essential for engineers to select and design the appropriate optocouplers under real application conditions.

With the rise of counterfeit optocouplers in the market, the J2200A is an excellent tool for incoming quality control (IQC), allowing engineers to identify genuine components. Its versatility makes it suitable for multiple applications, including:

• Circuit Design Tool: Assesses performance characteristics for isolated power circuit design.
• IQC Tester: Identifies counterfeit or out-of-specification optocouplers.
• CTR Ranking Classifier: Assists in categorizing optocouplers for efficient design processes.
