Best Alternatives to ESD05V14T-LC

Package: SOT-143GOODWORKTransient Voltage Suppressors (TVS)Reverse Working Voltage (Vrwm): 5VBreakdown Voltage (Vbr): 6.5V (min)Clamping Voltage (Vc): 10V @ 1A, 15V @ 6AJunction Capacitance (Cj): 0.3pF (I/O to I/O)Peak Pulse Current (Ipp): 6A (8/20µs)

ESD05V14T-LC replacements should be treated as review-required unless pinout, clamp, capacitance and IEC ESD ratings are confirmed.

AI replacement insight

Electrical riskmedium

Clamp, Ipp, Cj and ESD must match the line stress.

Package risklow

Kept candidates use SOT-143 4-pin.

Firmware risklow

Passive TVS device; no firmware impact expected.

Sourcing riskmedium

PDF checks and lifecycle fields are incomplete.

Can it be replaced directly?

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

Best replacement path

Start with SR05LC, then verify pinout, clamping and ESD ratings.

Main risk

Pinout and surge/ESD ratings are not fully proven.
