The Littelfuse SMDJ33A is a 3000W transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a reverse standoff voltage of 33V, a minimum breakdown voltage of 36.7V, and a maximum clamping voltage of 53.3V at a peak pulse current of 56.3A (10/1000µs waveform).
The device is unidirectional with one channel and offers excellent ESD protection up to 30kV (air and contact) per IEC 61000-4-2. It is housed in a surface mount DO-214AB (SMCJ) package with matte tin lead-free termination and is halogen-free and lead-free (Pb-free E3).
Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The SMDJ33A operates over a junction temperature range of -65°C to 150°C and has a typical response time of less than 1.0ps.

Estimated market price range - modelled values for guidance only, not live distributor offers.
The reverse standoff voltage (V_RWM) is 33V.
The maximum clamping voltage is 53.3V at a peak pulse current of 56.3A (10/1000µs waveform).
The peak pulse power dissipation is 3000W (3kW) for a 10/1000µs waveform.
The SMDJ33A is available in a DO-214AB (SMC) surface mount package, also referred to as DO-214AB (SMCJ).
The SMDJ33A is listed as RoHS3 compliant, but this status is unverified. Halogen-free and lead-free (Pb-free E3) are verified from the datasheet.
The SMDJ33A provides ESD protection up to 30kV for both air discharge and contact discharge per IEC 61000-4-2.
The operating junction temperature range is -65°C to 150°C.
