Maturity status link TSZ121 is the single version, TSZ122 the dual version, and TSZ124 the quad TSZ121 version, with pinouts compatible with industry standards. TSZ122 The TSZ12x series offers rail-to-rail input and output, excellent speed/power TSZ124 consumption ratio, and 400 kHz gain bandwidth product, while consuming less than 40 A at 5 V. The devices also feature an ultra-low input bias current.
