The Toshiba TLP7820 is an optically coupled (photocoupler-based) isolation amplifier designed for high-accuracy analog signal transmission across a galvanic isolation barrier. Built around sigma-delta analog-to-digital conversion technology with an analog output, it is ideal for sensing the small voltage developed across a shunt resistor in power-conversion systems. The device delivers 5000 Vrms isolation, low nonlinearity, and high common-mode transient immunity (CMTI), housed in a compact SO8L (LF4) 8-pin surface-mount package.
The Toshiba TLP7820 can see limited authorized-distributor stock, which may stall builds for motor-drive and inverter programs. Pacific Component Xchange is an independent distributor specializing in hard-to-find power-management ICs and optocouplers. We help engineers and buyers secure obsolete, allocated, and low-availability parts like the TLP7820 with rigorous authenticity verification and inspection. Submit an RFQ today for current pricing, lead times, and available date/lot codes. We support global shipping and can source the specific gain-rank and packaging variant your design requires.
The TLP7820 is an optically coupled (photocoupler) isolation amplifier from Toshiba. It transmits an analog signal across a 5000 Vrms galvanic isolation barrier using an LED and photodiode with sigma-delta conversion technology, and is intended for precision current and voltage sensing in motor drives and inverters.
The base device is the TLP7820. Orderable codes such as TLP7820(TP4,E), TLP7820(D4BLF4,E), and TLP7820(TL,E) add gain-rank and packaging suffixes (for example, tape-and-reel options). If you receive a garbled code, the base orderable device remains the TLP7820; contact us with the full string to confirm the exact variant.
The TLP7820 is supplied in an 8-pin SO8L (LF4) wide-body surface-mount package.
The TLP7820 provides 5000 Vrms of isolation (BVS) and is qualified to UL 1577, cUL, EN 60747-5-5, and EN IEC 62368-1 safety standards.
It is designed for motor phase current and voltage sensing, inverter current and voltage sensing, and shunt-resistor current sensing in electronic motor drives and industrial power conversion systems.
Yes. The TLP7820 is an RFQ (Request-For-Quote) item due to limited authorized-distributor availability. Submit an RFQ to Pacific Component Xchange for current pricing, lead time, available gain-rank/packaging variants, and date/lot codes, with global shipping available.
