The MMQA15VT1G is a quad common anode ESD protection diode from On Semiconductor's MMQA series. It is designed to protect four separate lines from transient overvoltage events in a single SC-74 package. This device features a reverse standoff voltage of 11V and a maximum clamping voltage of 21.7V at a peak pulse current of 1.1A (8/20µs waveform). It delivers a minimum peak pulse power of 150W for a 20µs pulse and 24W for a 1ms pulse, making it suitable for ESD protection in sensitive electronic equipment.
The diode offers low leakage current of less than 2.0µA and an ESD rating exceeding 16kV (HBM Class 3B). It is unidirectional with four channels, each configured with a common anode. The device is housed in a surface-mount SC-74 (SOT-457) package, which is compact and suitable for space-constrained PCB layouts.
With an operating temperature range of -55°C to 150°C, the MMQA15VT1G is suitable for general-purpose applications such as computers, printers, communication systems, and medical equipment. The device is Pb-Free and RoHS compliant, and thermal resistance is 556°C/W on FR-5 board and 417°C/W on alumina substrate, with total power dissipation of 225mW and 300mW respectively.
