Product Details
MAX4505EUK+T - Single High-Voltage Signal-Line Protector
MAX4505EUK+T from Analog Devices / Maxim Integrated is an always-on single-channel fault-protected analog signal path in a 5-pin SOT-23 tape-and-reel package.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
MAX4505 passes rail-to-rail analog signals during normal operation, opens the input path during an overvoltage fault and clamps the downstream output to the appropriate supply rail.
Key Advantages
Protects one analog input from faults up to +/-36 V when powered and +/-40 V when unpowered.
Keeps downstream circuitry at an unambiguous rail during faults and opens the path when supplies are off.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Single-channel high-voltage analog signal protector
Two-terminal always-on analog signal path
+9 V to +36 V single supply or +/-8 V to +/-18 V dual supply; -40 C to +85 C
SC-74A, SOT-753
Package & Footprint
This ordering code uses the SC-74A, SOT-753 package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.

Replacement Considerations
No exact MAX4505 alternative order code was found in the local database. Multi-channel protectors require circuit and footprint changes.
Manufacturer Information
Analog Devices lists MAX4505EUK+T in production. It is a signal-line protector, not a substitute for a high-energy surge arrester.
Applications
Protects sensitive ADC or amplifier inputs from wiring faults.
Guards analog channels near higher-voltage field wiring.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
What is the main function?
Single-channel high-voltage analog signal protector
What package is used?
