600W Zener TVS in DO-214AA – SMBJ60E3/TR13
The 107V clamping voltage at 5.6A peak pulse current defines the protection ceiling for the downstream circuitry.
Minimum breakdown voltage is 66.7V, so the part begins conducting at roughly 67V and clamps the transient to 107V maximum. For a 60V nominal rail, this leaves a 7V margin before the TVS starts leaking — tight but workable if the rail regulation is ±5%. The 5.6A peak pulse current at the 10/1000µs waveform is the current the part can sink during the surge; a lower-impedance source would push more current and exceed the 600W rating.
Active production – sourcing posture
The suffix indicates RoHS-compliant termination finish, so no separate RoHS exemption check is needed.
