Parameter Comparison

Engineering Selection Recommendations

Both SMBG9.0CA-M3/52 and SMBG9.0CA-E3/52 are active products with full RoHS3 compliance and REACH unaffected status. The primary distinction is the operating temperature range: the SMBG9.0CA-M3/52 supports -65°C to 175°C, while the SMBG9.0CA-E3/52 operates within -55°C to 150°C. Selection between these parts depends on the specific thermal requirements of the application. Both parts are electrically and mechanically equivalent across all transient voltage suppression parameters and package specifications.

Frequently Asked Questions (FAQ)

Q: Can SMBG9.0CA-E3/52 be used as a direct replacement for SMBG9.0CA-M3/52?

A: Yes, provided the application operating temperature range does not exceed -55°C to 150°C. The SMBG9.0CA-E3/52 has a narrower temperature specification than the SMBG9.0CA-M3/52. If the circuit operates within the -55°C to 150°C range, both parts are electrically and mechanically interchangeable.

Q: What are the key electrical parameters that define substitution compatibility?

A: The critical parameters are voltage reverse standoff (9V), breakdown voltage minimum (10V), clamping voltage maximum (15.4V), peak pulse current (39A), and peak pulse power (600W). Both parts are identical across these specifications.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the DO-215AA (SMB Gull Wing) package and are surface-mount components with identical footprints and soldering requirements.

Q: What is the difference between the part number suffixes M3 and E3?

A: The suffix indicates the tape and reel configuration for automated assembly. Both parts are supplied in Tape & Reel (TR) packaging. The electrical and mechanical specifications remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SMBG9.0CA-M3/52 and SMBG9.0CA-E3/52 are ROHS3 compliant with MSL rating of 1 (Unlimited).
