## Description
The SMCJ36A is a unidirectional transient voltage suppressor (TVS) diode engineered by Littelfuse within the TRANSZORB SMCJ product range. Built utilizing a glass passivated silicon chip architecture housed in a low-profile DO-214AB (SMC) surface-mount plastic package, this 2-pin component delivers robust circuit protection for sensitive electronics against high-energy transients induced by lightning and inductive load switching. The package features a flammability rating of V-0 per Underwriters Laboratories and incorporates built-in strain relief, ensuring high reliability in dense surface-mount board layouts.
Electrically, the SMCJ36A features a reverse standoff voltage ($V_R$) of 36 V and a maximum clamping voltage ($V_C$) of 58.1 V at a peak pulse current. The device exhibits a minimum breakdown voltage ($V_{BR}$) of 40.0 V and a maximum breakdown voltage of 44.2 V, tested at a 1 mA test current ($I_T$). Designed to handle demanding surge events, it offers a peak pulse power dissipation ($P_{PPM}$) of 1.5 kW using a standard 10/1000 µs waveform. Operating across a wide junction temperature range of -65°C to 150°C, the diode demonstrates exceptional thermal characteristics, including a typical junction-to-lead thermal resistance ($R_{\theta JL}$) of 15°C/W and a junction-to-ambient thermal resistance ($R_{\theta JA}$) of 75°C/W.
This TVS diode is ideally suited for deployment in power conversion architectures, telecommunications infrastructure, computer systems, and industrial automation equipment. Typical application circuits include the protection of high-speed I/O interfaces, DC power distribution rails, and VCC buses where suppression of electrostatic discharge (ESD) per IEC 61000-4-2 and electrical fast transients (EFT) per IEC 61000-4-4 is required. The device is fully compliant with RoHS standards and lead-free reflow soldering profiles up to 260°C for 30 seconds.
