The SMDJ78CA is a bidirectional Zener TVS diode from Littelfuse Inc., designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It is part of the SMDJ series, which offers 3000W peak pulse power dissipation capability (PPPM) for a 10/1000μs waveform.
Key electrical specifications include a reverse standoff voltage (VRWM) of 78V, a maximum clamping voltage (VC) of 126V, and a maximum peak pulse current (Ipp) of 23.8A. The device is rated for a peak forward surge current (IFSM) of 300A under an 8.3ms single half sine wave condition.
The SMDJ78CA is housed in a surface mount DO-214AB (SMC) package, suitable for automated assembly. It operates over a junction temperature range of -65°C to 150°C and has a storage temperature range of -65°C to 175°C. Typical thermal resistance is 15°C/W from junction to lead and 75°C/W from junction to ambient.
The reverse standoff voltage (VRWM) is 78V.
The maximum clamping voltage (VC) is 126V.
The maximum peak pulse power (PPPM) is 3000W for a 10/1000μs waveform.
The SMDJ78CA is available in a DO-214AB (SMC) surface mount package.
The operating junction temperature range is -65°C to 150°C.
