Best Alternatives to SRV05-4HTG

Package: SOT23-6LeiditechTransient Voltage Suppressors (TVS)Reverse Working Voltage: 5 VBreakdown Voltage: 6 VCapacitance (I/O to I/O): 0.35 pFESD Protection (Air/Contact): ±25 kVNumber of Channels: 4

SRV05-4HTG replacements need careful review because supplied candidates lack pinout proof and are mostly 5V parts.

AI replacement insight

Electrical riskhigh

Candidates are 5V vs target 6V.

Package risklow

Kept parts list SOT23-6.

Firmware risklow

Passive TVS device.

Sourcing riskmedium

Lifecycle is mixed or blank.

Can it be replaced directly?

No verified pin-compatible replacement is proven from the supplied data.

Best replacement path

Start with same-package 4-line TVS parts, then verify pinout, 6V standoff, 10A surge, and leakage.

Main risk

Lower 5V standoff and missing pinout evidence.
