Name: ADT6402SRJZ-RL7 Analog Devices Temperature Switch | SOT-23-6
Brand: Analog Devices
SKU: ADT6402SRJZ-RL7

ADT6402SRJZ-RL7 is a programmable temperature switch from Analog Devices designed for local temperature monitoring and threshold detection. It integrates an internal band gap temperature sensor and provides an active-high push-pull logic output when the selected temperature trip point is crossed. The device supports pin-selectable trip points, selectable hysteresis, low typical supply current, and operation from 2.7 V to 5.5 V, making it suitable for compact thermal protection and system monitoring designs.

Summary

Comparison Models

Part Number	Comparison Note
ADT6401SRJZ-RL7	Closest related model; similar temperature switch family and SOT-23-6 package, but ADT6401 uses an active-low open-drain output, while ADT6402 uses an active-high push-pull output.
ADT6402SRJZ-RL7	Best choice when the design needs active-high push-pull temperature alarm output without an external pull-up resistor.
ADT6401	Base family alternative for systems that require open-drain output behavior or wired-OR alarm connection.
ADT6402	Base family reference for the same push-pull active-high output architecture; confirm exact suffix and packaging before ordering.

Replacement Note

ADT6402SRJZ-RL7 should generally be replaced with the same full ordering code when maintaining an existing PCB design, because output polarity, output type, package, pin configuration, trip-point selection, and reel packaging all matter. ADT6401SRJZ-RL7 is not a direct drop-in functional equivalent unless the circuit is designed for active-low open-drain output behavior.

Sourcing Tip

For procurement, confirm the full suffix SRJZ-RL7: SRJ indicates the SOT-23 package option, Z indicates RoHS-compliant package, and RL7 indicates reel packaging. For production orders, also verify reel quantity, date code, MSL handling, and whether cut tape or full reel is required.
