Replacement Compatibility
ProTek parts are compatible when:
- Same series (TVS vs TVS, GBLC vs GBLC)

- Same or higher power (for TVS/SMD series)

Lead-free (-LF) variants are interchangeable with standard variants:
- PSM712 and PSM712-LF are functionally identical
- -LF suffix only indicates RoHS compliance

Application Selection Guide
| Application | Recommended Series | Notes | |-------------|-------------------|-------| | Power supply protection | TVS, SMD | Higher power handling | | USB/HDMI ESD | GBLC | Low capacitance | | RS-232/RS-485 | PSM712 | Multi-line protection | | High-speed data | ULC | Ultra-low capacitance | | Automotive | PSM, GBLC15C | Voltage tolerance |
Learnings & Edge Cases
- GBLC always bidirectional: The "C" suffix indicates bidirectional, all GBLC parts have this
- PSM712 specific: PSM712 is specifically for RS-232, uses 7V standoff for +/-12V signals
- SMD naming: SMD series is named for package type, not to be confused with generic "SMD" term
- ULC line count: Second 2 digits indicate number of protection lines (12, 24)
- Voltage encoding varies: TVS uses 3 digits (divide by 10), GBLC uses 2 digits, SMD uses last 2 digits
- Lead-free interchangeable: -LF suffix only affects manufacturing process, electrically identical
