Built on a glass-passivated junction configuration within a low-profile DO-214AB (SMC) package featuring two matte tin-plated leads, this component delivers a peak pulse power dissipation of 1.5 kW for a 10/1000 µs waveform. It exhibits a reverse standoff voltage ($V_{WM}$) of 78 V, a minimum breakdown voltage ($V_{BR}$) of 86.7 V, and a maximum breakdown voltage of 95.8 V at a test current of 1 mA. Designed for robust circuit protection, the SMCJ78A provides a maximum clamping voltage ($V_C$) of 126 V while maintaining an extremely fast response time of typically less than 1.0 picosecond from 0 volts to its minimum breakdown voltage. The device operates across a wide junction and storage temperature range of -55°C to +150°C, supported by a junction-to-ambient thermal resistance of 55°C/W and a junction-to-case thermal resistance of 10°C/W. Its low reverse leakage current profile ensures minimal parasitic loading during normal operating conditions. This unidirectional TVS diode is well-suited for deployment in automotive subsystems, telecommunications infrastructure, industrial automation equipment, and consumer electronics power lines. It effectively mitigates electrostatic discharge (ESD) events and clamping transients induced by inductive load switching and lightning surges. The molding compound carries a UL 94V-0 flammability rating, and the hardware is fully compliant with RoHS Directive 2011/65/EU and IEC 61249-2-21 halogen-free standards. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (27-Jun-2018) | | No. Of Pins | 2Pins | | Tvs Polarity | Unidirectional | | Product Range | SMCJ | | Qualification | - | | Diode Mounting | Surface Mount | | Diode Case Style | DO-214AB (SMC) | | Clamping Voltage Max | 126V | | Reverse Standoff Voltage | 78V | | Maximum Breakdown Voltage | 95.8V | | Minimum Breakdown Voltage | 86.7V | | Operating Temperature Max | 150°C | | Peak Pulse Power Dissipation | 1.5kW | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2981443/) ## **SMCJ5.0(A) - SMCJ170(A)** Gb TAIWANSEMICONDUCTOR[gee Taiwan Semiconductor ## **1500W, 5V - 170V Surface Mount Transient Voltage Suppressor** ## FEATURES - Low profile package - Ideal for automated placement - Glass passivated junction - Built-in strain relief - Excellent clamping capability - Fast response time: Typically less than 1.0ps from 0 volt to BV min - Typical IR less than 1μA above 10V - Compliant to RoHS Directive 2011/65/EU and in accordance to WEEE 2002/96/EC |KEY PARAMETERS|KEY PARAMETERS|KEY PARAMETERS| |---|---|---| |PARAMETER|VALUE|UNIT| |VWM|5 - 170|V| |VBR|6.4 - 209|V| |PPK|1500|W| |TJ MAX|150|°C| |Package|DO-214AB (SMC)|| |Configuration|Single die|| - Halogen-free according to IEC 61249-2-21 ## APPLICATIONS - Immunization of sensitive devices in automotive, telecommunications, consumer electronics, and industrial equipment from electrostatic discharge (ESD) and transient voltages induced by load switching and lightning. ## MECHANICAL DATA - Case ： DO-214AB (SMC) - Molding compound meets UL 94V-0 flammability rating - Part no. with suffix "H" means AEC-Q101 qualified - Packing code with suffix "G" means green compound (halogen-free) **DO-214AB (SMC)** - Moisture sensitivity level: level 1, per J-STD-020 - Terminal ： Matte tin plated leads, solderable per J-STD-002 - Meet JESD 201 class 2 whisker test - Polarity ： As marked - Weight ： 0.21 g (approximately) |ABSOLUTE MAXIMUM RATINGS (TA= 25°C unless otherwise noted)|ABSOLUTE MAXIMUM RATINGS (TA= 25°C unless otherwise noted)|ABSOLUTE MAXIMUM RATINGS (TA= 25°C unless otherwise noted)|ABSOLUTE MAXIMUM RATINGS (TA= 25°C unless otherwise noted)| |---|---|---|---| |PARAMETER|SYMBOL|VALUE|UNIT| |Peak power dissipation at TA=25°C, Tp=1ms(1)|PPK|1500|W| |Steady state power dissipation at TA=25°C|PD|5|W| |Peak forward surge current, 8.3 ms single half sine-wave
