ADUM1200WSRZ53

Overview

The ADUM1200WSRZ53 is a discontinued automotive-grade digital isolator from Analog Devices Inc. It features two unidirectional channels utilizing magnetic coupling technology to provide electrical isolation. The device operates within a supply voltage range of 3V to 5.5V and supports data rates up to 1Mbps. Key electrical specifications include an isolation voltage of 2500Vrms, a minimum common-mode transient immunity of 25kV/µs, and a maximum propagation delay of 150ns. It is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm) and functions reliably across a temperature range of -40°C to +125°C.

Procurement Notes

This component has been officially declared obsolete by the manufacturer. Procurement must focus on verifying the authenticity of remaining stock or identifying approved parameter-equivalent replacements. Buyers should confirm that substitute parts meet the specific automotive grade requirements and pinout compatibility necessary for their existing designs.

Selection Notes

Designers requiring this specific part number must evaluate alternative components due to its end-of-life status. Selection criteria should prioritize matching the 2500Vrms isolation rating, SOIC-8 footprint, and automotive temperature range. Verify that any replacement maintains the required 1Mbps data rate and unidirectional channel architecture to ensure circuit functionality remains intact.

Part Context

The ADUM1200 series represents Analog Devices' magnetic coupling-based digital isolators designed for high-reliability applications. This specific variant belongs to the automotive product line, ensuring compliance with stringent industry standards for vehicle electronics. The family is known for integrating isolation barriers directly onto the silicon die to minimize size and maximize performance.

Replacement Considerations

Public confirmed substitutes include ADUM1200WURZ and ADUM1200WSRZ-RL7. These alternatives offer parameter equivalence and maintain the same functional characteristics and packaging style suitable for direct design-in consideration.
