Is there a pin-compatible replacement for SRV05-4.TCT?

SRV05-4-P-T7 and various versions of SRV05-4 share the SOT-23-6 package and are designed for the same function, making them likely pin-compatible. However, direct pinout confirmation from the datasheets is essential before board layout.

What risks should I check before replacing SRV05-4.TCT?

Key risks include mismatched clamping voltage, peak power rating, and line capacitance. Ensure the replacement's clamping voltage is not higher, its power rating is equal or greater, and its capacitance is suitable for your data rate. Also, confirm the pinout is identical.
