Its 160 V clamping voltage at 3.8 A peak pulse current (10/1000 µs waveform) defines the protection ceiling — any downstream component must withstand that voltage for the pulse duration.
The SMB footprint is common across the SMBJ family, simplifying last-minute BOM swaps.
The base product number SMBJ90 covers multiple package and reel options, so the die itself is a standard catalog item. No minimum order threshold beyond standard reel increments.
Design engineers need the official datasheet for pinout, electrical specs, and absolute maximum ratings to validate fit.
Sourcing buyers prioritize real-time stock availability from distributors to avoid production delays.
Buyers need pricing for BOM costing and budget approval; competitive pricing influences distributor choice.
Engineers often conflate similar part numbers; clarifying differences prevents design errors and wrong orders.
Maintenance techs and brokers need cross-reference equivalents for substitution when original parts are unavailable.
Lead time directly affects procurement planning and risk of line-down situations for buyers.
