STMicroelectronics 4, 3 V Zener Diode, Single Surface 5-Pin SOT-666

These devices are monolithic suppressors designed to protect components connected to data and transmission lines against ESD. They clamp the voltage just above the logic level supply for positive transients and to a diode drop below ground for negative transients.

• 4 unidirectional Transil functions
• Breakdown voltage VBR = 6.1 V min
• Low leakage current < 100 nA
• Low diode capacitance (7.5 pF at 3 V)
