At that pulse, the clamping voltage holds at 85V maximum while passing 17.9A of peak pulse current. Unidirectional construction (one channel) means it protects a single polarity rail — positive transients above the breakdown voltage are clamped to ground; negative transients forward-bias the junction and are clamped near 1V. For a 53V positive supply, this is the correct polarity. ## Package and board-fit: DO-214AA (SMB) surface mount Housed in a DO-214AA (SMB) package, also designated as the supplier device package DO-214AA (SMBJ). The SMB footprint is larger than the SMA sibling, which translates to a lower thermal resistance junction-to-board — important for sustaining repetitive pulse trains without exceeding the -65°C to +150°C junction temperature range. The surface-mount package suits high-volume telecom line card production where through-hole TVS parts have been phased out. ## Active production and sourcing posture No stock-holding claim — each RFQ is handled on its own lead-time and lot-traceability terms.","metaTitle":"Littelfuse 1.5SMB62A TVS Diode, 1.5kW, DO-214AA","metaDescription":"Littelfuse 1.5SMB62A Zener TVS, 1500W peak pulse, 58.9V breakdown, 85V clamping, DO-214AA SMB.
