Housed in a JEDEC DO-214AB (SMC) package, this component features a glass-passivated junction capable of dissipating up to 1.5 kW of peak pulse power on a 10/1,000 Āµs waveform. With a reverse standoff voltage of 33 V, a minimum breakdown voltage of 36.7 V, and a maximum clamping voltage of 53.3 V, it provides robust protection against voltage transients and electrostatic discharge (ESD) in sensitive electronic systems. Engineered for reliability, the SMCJ33CA offers a fast response time of typically less than 1 ps from 0 V to the minimum breakdown voltage. The device is rated for an operating junction and storage temperature range of -55Ā°C to +150Ā°C, ensuring stability in demanding industrial and automotive environments. Its low-profile, two-pin package includes built-in strain relief and solder-plated terminals, facilitating efficient automated assembly processes. This TVS diode is suitable for signal line protection, power supply rail clamping, and general-purpose surge suppression where bidirectional protection is required to mitigate transient overvoltage events. ## Specifications | Parameter | Value | |---|---| | Svhc | Lead (25-Jun-2025) | | No. Of Pins | 2Pins | | Tvs Polarity | Bidirectional | | Product Range | SMCJ | | Qualification | - | | Diode Mounting | Surface Mount | | Diode Case Style | DO-214AB (SMC) | | Clamping Voltage Max | 53.3V | | Reverse Standoff Voltage | 33V | | Maximum Breakdown Voltage | 40.6V | | Minimum Breakdown Voltage | 36.7V | | Operating Temperature Max | 150Ā°C | | Peak Pulse Power Dissipation | 1.5kW | ## Datasheet šŸ“„ [Download PDF](https://novapart.co/datasheet/farnell:2675415RL/) ## **SMBJ / SMCJ Series Surface Mount Voltage Suppressors** ## **Features** - For surface mounted applications in order to optimise board space - Low profile package - Built-in strain relief - Glass passivated junction - Excellent clamping capability - Low inductance - Typical ID less than 1Ī¼A above 10V ## **Specifications** Repetition Rate (duty cycle) : 0.05% (SMCJ) 0.01% (SMBJ) Fast Response Time : Typically less than 1 ps from 0 volts to BV min.
