Frequently Asked Questions
What are the key voltage parameters of the SMC5K36A-M3/H TVS diode?
The SMC5K36A-M3/H has a 36 V standoff voltage, a nominal breakdown voltage of 42.1 V (range 40–44.2 V), and a maximum clamping voltage of 58.1 V at peak pulse current. This clamping window ensures transient voltages above 36 V are absorbed while the protected circuit sees no more than 58.1 V during a worst-case surge event.
Why is the 5000 W peak pulse power rating of SMC5K36A-M3/H significant for industrial protection circuits?
A 5000 W peak pulse power rating allows the SMC5K36A-M3/H to safely absorb high-energy transients such as inductive load switching spikes and lightning-coupled surges on 36 V industrial bus lines without failure. This high surge handling, combined with the SMC package's excellent thermal performance, makes it suitable for protecting PLCs, servo drives, and 24 V field device interfaces from repeated transient stress.
When should an engineer choose SMC5K36A-M3/H over a lower-rated TVS diode for a 36 V rail?
When a 36 V power rail is exposed to high-energy transients from inductive switching, hot-plug events, or nearby lightning strikes in unshielded industrial wiring, the 5000 W SMC5K36A-M3/H provides margin that 1500 W or 3000 W alternatives cannot safely handle. The SMC package also dissipates more heat than SOD-123 or SMA packages, extending the device's life over thousands of surge cycles in rugged field conditions.
