TLP137(BV-TPR,F)

Overview

The TLP137(BV-TPR,F) is a mini flat coupler manufactured by Toshiba Semiconductor and Storage, designed for surface mount assembly. It integrates a gallium arsenide infrared emitting diode optically coupled to a phototransistor output. The device provides high current transfer ratio at low input currents, ensuring efficient signal transmission. Key electrical specifications include a collector-emitter voltage of 80 V minimum and an isolation voltage of 3750 Vrms minimum. The BV rank guarantees a current transfer ratio of 200% minimum. This component is suitable for applications requiring compact size and reliable optical isolation in digital circuits.

Feature Summary

• Integrates a gallium arsenide infrared LED with a phototransistor for high-speed optical coupling
• Provides high current transfer ratio performance at low input drive currents
• Features a mini flat outline package optimized for automated surface mount assembly processes
• Ensures robust electrical isolation with a minimum isolation voltage rating

Applications

• Office machines such as printers and copiers
• Programmable logic controllers (PLCs)
• AC/DC input modules for industrial automation
• Telecommunication equipment interfaces

Procurement Notes

Verify the specific suffix BV-TPR,F against official Toshiba documentation to confirm the current transfer ratio ranking and tape-and-reel packaging configuration. Ensure that the component's lead-free status and RoHS compliance meet current regulatory requirements for your target market. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity, as supply chain statuses may vary over time.

Selection Notes

Select this component when a compact surface-mount solution is required for isolating control signals from power circuits. The high CTR at low input current makes it suitable for battery-operated or low-power systems. Consider the 80 V collector-emitter voltage limit for switching applications. Verify that the operating temperature range aligns with the environmental conditions of the intended deployment scenario.

Part Context

The TLP137 belongs to Toshiba's mini flat coupler series, which focuses on reducing footprint while maintaining high performance. This series is widely used in consumer electronics and industrial control systems where space constraints are critical. The BV variant specifically denotes a higher binning for current transfer ratio, offering enhanced gain compared to standard ranks within the same package family.

Replacement Considerations

Direct substitutes must match the MFSOP-6 package, NPN phototransistor output, and similar isolation voltage ratings. Check datasheets for equivalent current transfer ratios and forward voltage characteristics to ensure circuit compatibility without redesign.
