PIN-TO-PIN ALTERNATIVE
TPT7720-SO1R is a Chinese-manufactured pin-to-pin drop-in replacement for ADuM1200 (Analog Devices).
3PEAK's pin-compatible isolator family, with AEC-Q100 qualified variants for automotive designs.
TPT7720-SO1R — Alternative to ADuM1200
TPT7720-SO1R from 3PEAK {BRAND} is supplied by JTDZ Tech (Shenzhen Jingteng Electronics) as a cost-effective, short-lead-time alternative to the imported ADuM1200 (Analog Devices). Chinese-sourced semiconductors have moved well beyond "cheap substitute" status: the parts below are production-validated in industrial, automotive and consumer designs, and they remove both the allocation risk and the long lead times that come with imported.

What to check before substituting TPT7720-SO1R for ADuM1200
- Same SOP-8 footprint as ADuM1200-class isolators, so no layout change.
- Capacitive silicon-dioxide barrier technology with fail-safe default output.
- Channel direction matters: TPT7720 is 2 forward / 0 reverse (ADuM1200 equivalent); choose TPT7721 or TPT7722 for 1 forward / 1 reverse (ADuM1201 equivalent).
- The -S suffix variant is AEC-Q100 qualified for automotive use.
Typical Applications
- Industrial automation and motor control
- Isolated data acquisition
- Power conversion and new-energy systems
- Automotive-grade isolation (with -S variant)
