Excellent alternative from Yageo with a higher power rating (150W vs 130W) in the same package.
RLSD52A051C is a 5V bidirectional TVS diode in a SOD-523 package. Several potential alternatives exist, including upgrades with higher power ratings and pin-compatible options that require careful review of electrical parameters.
Substitutes may have lower power ratings or different clamping voltages. Verification is required.
All reviewed candidates use the same SOD-523 package, ensuring form and fit compatibility.
As a passive protection device, there is no firmware impact.
No drop-in replacement is confirmed without full datasheet review, but SBD52C05L01 is a strong pin-compatible candidate with a higher power rating.
Use an upgrade path candidate like Yageo SBD52C05L01 or SINO-IC TVSS5VCES-02GP-J, which offer higher power handling.
The main risk is selecting a substitute with a lower peak pulse power rating, which could lead to device failure under surge conditions.
