1.5 kW Zener TVS in a DO-13 can
The 1N6059A is a Zener-type transient voltage suppressor from Microchip Technology, rated for 1500 W (1.5 kW) peak pulse power per the 10/1000 µs waveform. That 1.5 kW rating is the headline surge capacity — it tells you this part can absorb a significant energy pulse without failing short, which is the first question a protection engineer asks when sizing a clamp for a 58 V rail. Bidirectional single-channel device, so it clamps both polarities of a transient with one component. No power line protection — this is a signal or low-power rail clamp, not a mains-side MOV replacement.
Clamping window and pulse current
Reverse standoff voltage is 58 V typ; breakdown minimum is 64.6 V. The clamping voltage at the rated peak pulse current of 16.3 A is 92 V max. The 16.3 A peak pulse current is specified for the 10/1000 µs waveform, the standard telecom surge shape.
Active production and package reality
That means this is a franchised-distribution line, not a scavenger hunt across independent brokers. The DO-13 (DO-13) through-hole package is a metal can with two leads; it is not a surface-mount part, so plan for a through-hole assembly step or a hand-solder rework station. The 175°C ceiling is unusual for a TVS — most plastic-packaged parts stop at 150°C. That extra thermal headroom matters if the clamp sits near a hot power stage or inside a sealed enclosure with no airflow.
