TLP182(TPL,E

Overview

The TLP182(TPL,E is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared emitting diode coupled to an NPN phototransistor within a compact SOP-4 surface-mount package. The device provides high isolation with a rated insulation voltage of 3750 Vrms, ensuring safe signal transmission between isolated circuits. Key electrical characteristics include a maximum collector-emitter voltage of 80 V and a continuous collector current of 50 mA. The unit operates reliably across a wide temperature range from -55°C to +125°C, making it suitable for industrial applications requiring robust performance under varying thermal conditions.

Feature Summary

• Provides galvanic isolation between input and output circuits using infrared LED and phototransistor technology
• Features a compact SOP-4 surface-mount package designed for automated assembly processes
• Delivers high insulation voltage capability to protect sensitive low-voltage control sides from high-voltage loads

Applications

• Industrial automation control systems
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix (TPL,E) confirms the tape-and-reel packaging format required for your manufacturing line. Confirm RoHS compliance status through official Toshiba documentation prior to integration. Ensure the ordering quantity aligns with the standard reel size specifications provided in the product datasheet to avoid handling discrepancies during production.

Selection Notes

Select this component when a small footprint and high isolation voltage are prioritized over switching speed. The TLP182 series offers a balance of cost-effectiveness and reliability for general-purpose isolation tasks. Consider the CTR range and saturation voltage requirements of your specific load circuit to ensure adequate drive capability without excessive power dissipation in the phototransistor.

Part Context

This part belongs to the TLP182 family of transistor output optocouplers. Variants within this series differ primarily in packaging formats such as tube or reel configurations, and specific environmental qualifications like lead-free plating. The TPL,E designation specifically indicates the reel-packaged version compliant with modern environmental standards, distinguishing it from older bulk-packed alternatives.

Replacement Considerations

Direct pin-compatible substitutes within the same Toshiba lineup include TLP182(GB-TPL,E and TLP182(GR-TPL,E. These variants share identical electrical characteristics but may differ in packaging type or specific regulatory certifications. Verify that any replacement maintains the required SOP-4 footprint and insulation voltage ratings.
