Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE56CA-/73 suits through-hole assembly on boards or terminal strips where the lead bend absorbs board flex. The junction temperature range spans -55°C to 175°C, covering hot environments like power-supply outputs or motor-drive DC buses without derating at the high end. The Tape & Box (TB) packaging option (/73 suffix) feeds axial-insertion machines with the leads oriented consistently — the same die as the bulk-packaged 1.5KE56CA, just in a machine-ready format. ## Sourcing and compliance Listed as Active by Vishay — no last-time-buy window or successor part number has been issued. The part carries no power-line protection rating (: No), so it is intended for signal-line and low-voltage DC rail transient suppression rather than AC mains clamping. Standard compliance documentation (RoHS, REACH) is maintained by Vishay for this series.","metaTitle":"1.5KE56CA-E3/73 Vishay TVS, 1500W Bidirectional, DO-201AA","metaDescription":"Vishay 1.5KE56CA-E3/73 TransZorb TVS diode, 1500W peak pulse, 47.8V standoff, bidirectional, DO-201AA axial.
