TPT7482-SOBR

Drivers, Receivers, Transceivers Overview

The TPT7482-SOBR is an isolated full-duplex RS-485 transceiver from 3PEAK, characterized by a 20-Mbps data rate and operation within a 3.0 V to 5.5 V supply voltage range. It features a 5-kV RMS isolation rating with ±200-kV/μs typical static common-mode transient immunity (CMTI). The device includes hot-plug circuitry that maintains three-state outputs during power-up or power-down events. Bus-pin protection supports ±15-kV IEC 61000-4-2 contact discharge and ±20-kV air discharge. It presents a true 1/8 unit load, allowing up to 256 nodes on the network. The component is housed in a WSOP16 package and operates across a temperature range of −40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Isolated full-duplex architecture supporting high-speed 20-Mbps communication
• Robust bus-pin protection against electrostatic discharge and transient events
• Full fail-safe receiver design ensuring logic-high output under open, short, or idle conditions

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'SOBR' corresponds to the tape and reel packaging configuration containing 1500 units per reel. Confirm the MSL3 classification aligns with your facility's soldering reflow profile capabilities. Ensure the green RoHS-compliant material specification meets your environmental compliance requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the TPT7482-SOBR when full-duplex isolated RS-485 communication is required at speeds up to 20 Mbps. This model is appropriate for designs needing a 5-kV RMS isolation barrier and robust ESD protection. Compare it against the half-duplex TPT7481 if bidirectional single-wire communication suffices. Verify that the WSOP16 package dimensions fit the available PCB footprint constraints.

Drivers, Receivers, Transceivers Part Context

The TPT7482 belongs to the TPT748x family of isolated RS-485 transceivers manufactured by 3PEAK. This series utilizes proprietary isolation IP technology to provide safety-related certifications including VDE, UL, CSA, TUV, CQC, and CB. The family shares similar electrical characteristics and thermal performance metrics, differentiated primarily by duplex mode and pin configurations.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the verified source material. Designers should consult official 3PEAK documentation for qualified alternatives or cross-reference with other isolated RS-485 transceivers meeting identical isolation and speed specifications.
