1500 W peak pulse — TransZorb unidirectional TVS
The 1.5KE56A-E3/73: It clamps transients at 77 V maximum, with a reverse standoff of 47.8 V and a minimum breakdown of 53.2 V — the typical protection window for 48 V rails in industrial and telecom supplies.
Package and thermal reach
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE56A-/73 is a through-hole part suited for point-of-entry transient suppression on power or signal lines. The junction temperature range spans -55°C to +175°C, covering hot environments like engine bays or industrial enclosures without derating concerns.
