Has stronger power/current ratings but much higher capacitance, which may be unsuitable for the application.
SRV05-4-HXY is a 5-channel, 5V TVS diode array in a SOT-23-6L package, optimized for protecting high-speed data lines with its ultra-low 0.4pF capacitance. Finding a substitute requires careful matching of this low capacitance to maintain signal integrity.
Capacitance is a critical parameter for this high-speed part and varies among candidates.
All candidates share the SOT-23-6L package, but pinout must be verified.
Multiple manufacturers offer similar parts, providing sourcing flexibility.
Direct replacement for SRV05-4-HXY should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
SRV05-4.TCT-JSM appears to be the best path, offering upgraded specs, but requires pinout verification.
Capacitance mismatch is the main risk, potentially degrading signal integrity in high-speed applications.

|---|---|---|---|---|---|
| Package | SOT-23-6L | SOT-23-6L | SOT-23-6L | SOT23-6L | SOT-23-6L / SOT23-6L — Package matches, but pinout requires verification.; SRV05-4.TCT-JSM: Package matches, but pinout requires verification.; SRV05-4LA 4A: Package matches, but pinout requires verification. |
| Voltage | 5.0V | 5.0V | 5.0V | 5.0V | 5.0V — Working voltage matches.; SRV05-4.TCT-JSM: Working voltage matches.; SRV05-4LA 4A: Working voltage matches. |
| Current | 4.0A | 5.0A | 5.0A | 4.0A | 5.0A / 4.0A — Higher peak pulse current rating.; SRV05-4.TCT-JSM: Higher peak pulse current rating.; SRV05-4LA 4A: Peak pulse current matches. |
| Capacitance | 0.4pF max | 0.8pF | 0.35pF | 0.5pF | 0.8pF / 0.35pF / 0.5pF — Capacitance is double the target's, posing a risk to signal integrity.; SRV05-4.TCT-JSM: Lower capacitance is an upgrade for high-speed lines.; SRV05-4LA 4A: Slightly higher capacitance may affect high-speed signals. |
| Power | 55W | - | missing | 60W | missing / 60W — Power rating not found in structured data.; SRV05-4LA 4A: Higher power rating provides more margin. |
Verified drop-in options for SRV05-4-HXY are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
