Product Description
Taiwan Semiconductor SMCJ28A is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) Diode designed for protecting electronic components from voltage spikes and transient surges. It provides a peak pulse power dissipation of 1.5 kW and is housed in a compact DO-214 surface mount package with two pins.
This diode features a minimum breakdown voltage (Vbr) of 31.1V and a maximum reverse stand-off voltage (Vwm) of 28V. It clamps voltage spikes to a maximum 45.4V clamping voltage (Vc) with a peak pulse current (Ippm) rating of 33A, protecting circuits against transient high voltage events effectively.
The device operates safely across a temperature range from -55°C to 150°C, enabling its use in diverse industrial, automotive, and consumer electronic applications. Its low maximum reverse leakage current of 5 μA ensures minimal power loss during normal operation.
The 2-pin DO-214 package measures 7.15mm in length, 6.25mm in width, and 2.75mm in height, suitable for compact PCB layouts. The diode contains a single element per chip and uses glass-passivated junction technology that enhances reliability and surge resistance.
This TVS diode series SMCJ is ideal for transient voltage suppression in power management, industrial control, automotive electronics, and communications equipment. It complies with recognized standards making it suitable for high-reliability applications.
Single diode configuration designed for uni-directional transient voltage suppression. Surface mount suitable DO-214 package with compact form factor. High peak pulse power rating of 1.5 kW for transient surge protection.
Wide operating temperature range from -55°C to 150°C supports diverse applications. Glass-passivated junction improves durability and surge resistance. Low reverse leakage current reduces power loss during normal operation.
