That 59 V ceiling is the hard limit the protected IC sees during a surge — important when the downstream part has a 60 V abs-max rating. It is a single bidirectional channel, so one device clamps both polarities on a signal pair or DC rail. ## DO-214AA surface-mount package and temperature range Housed in a DO-214AA (SMB) package, also designated as supplier device package DO-214AA (SMBJ). Surface-mount only — no through-hole variant in this series. The operating junction temperature range spans -65°C to 150°C, covering telecom outdoor cabinets and industrial enclosures without derating concerns at the hot end.","metaTitle":"Littelfuse 1.5SMB33CA TVS Diode, 1500W, DO-214AA","metaDescription":"Littelfuse 1.5SMB33CA bidirectional Zener TVS, 1500W peak pulse, 28.2V standoff, DO-214AA.
