When a surge hits, the device breaks down at a minimum of 36.7V and clamps the voltage to a maximum of 59V at the rated peak pulse current of 10.2A. The part is a single unidirectional channel, so it protects one polarity. For AC or bidirectional lines, you would need two devices back-to-back or a dedicated bidirectional TVS. ## Package, temperature range, and storage reality ## Lifecycle status — active, no EOL watch needed For a spare-parts storeroom, this part is a safe long-term stock item — no last-time-buy scramble expected in the near term. ## Sourcing this part through distribution Because the part is Active and a standard Microchip catalog item, it is available through authorized distribution channels. Pricing and lead time vary with quantity and market conditions — submit an RFQ for current availability against your BOM line.","metaTitle":"SMBJ33E3/TR13 Zener TVS Diode – 33V, 600W","metaDescription":"SMBJ33E3/TR13 from Microchip Technology: Zener TVS diode, 33V reverse standoff, 600W peak pulse, DO-214AA (SMB) package.
