4N33S(TA)-V

Overview

The 4N33S(TA)-V is a single-channel optocoupler featuring a GaAs infrared LED coupled to a photodarlington transistor output. It provides electrical isolation with a minimum isolation voltage of 5000 Vrms and a peak breakdown voltage of 55 V. The device operates within a temperature range of -55°C to 100°C. Key electrical parameters include a minimum current transfer ratio (CTR) of 500% at 10 mA forward current, a maximum DC forward current of 60 mA, and a typical forward voltage of 1.2 V. Switching characteristics specify a maximum turn-on time of 5 µs and a maximum turn-off time of 100 µs.

Feature Summary

• Integrates an infrared emitting diode with a high-gain photodarlington transistor for enhanced signal transmission.
• Provides robust electrical isolation between input and output circuits to ensure system safety.
• Features zero-crossing detection capabilities suitable for precise timing applications.

Applications

• Digital logic signal transmission and level shifting
• Power supply control and switching circuits

Procurement Notes

Verify the specific suffix TA against the manufacturer's latest datasheet to confirm package type and compliance status. Ensure the procurement channel sources directly from Everlight Electronics Co., Ltd. or authorized distributors to guarantee component authenticity. Check for any recent product change notifications that may affect specifications or packaging details before finalizing orders.

Selection Notes

Select this component when high current transfer ratio is required for driving loads with minimal input current. The SMD 6-pin package facilitates surface mount assembly. Consider the switching speed limitations compared to standard phototransistor variants if high-frequency operation is critical. Verify thermal management requirements given the operating temperature range and power dissipation constraints.

Part Context
