TLPN137(F)

Overview

The TLPN137(F) is a high-speed logic output coupler manufactured by Toshiba Semiconductor and Storage. It features a single channel with one input and zero outputs on the secondary side, utilizing a transistor output configuration. The device provides an isolation voltage of 5000Vrms. Key timing parameters include a typical rise time of 3ns and fall time of 12ns, with maximum propagation delays (tpLH/tpHL) of 75ns. The component is housed in a compact package suitable for surface mount applications.

Feature Summary

• High-speed logic output coupling capability
• High isolation voltage rating
• Compact surface mount packaging

Applications

• Digital signal isolation in industrial control systems
• Microprocessor interface circuits
• Logic level translation between isolated domains

Procurement Notes

Verify current availability status as the TLPN137(F) may be obsolete or no longer manufactured according to some sources. Confirm specific suffix requirements such as (F) for tape and reel packaging if applicable. Ensure compatibility with RoHS standards and lead-free specifications when sourcing replacements or checking stock from authorized distributors.

Selection Notes

Select this component for applications requiring fast switching speeds and high isolation voltage in a small form factor. Consider the 75ns propagation delay limit when designing high-frequency digital interfaces. Verify that the transistor output type matches the load requirements of the receiving circuitry. Check package dimensions against PCB layout constraints.

Part Context

This part belongs to Toshiba's TLPN series of high-speed optocouplers designed for digital communication and logic interfacing. The series typically offers improved speed performance compared to standard transistor output optocouplers. The TLPN137 variant specifically targets applications needing rapid signal transmission across isolation barriers while maintaining electrical safety standards.

Replacement Considerations

Check for direct substitutes within the TLPN series or equivalent high-speed logic output optocouplers from other manufacturers. Verify pinout compatibility and electrical parameter equivalence, particularly isolation voltage and propagation delay. Note that some sources indicate this part may be discontinued.
