Photorelays TLP3417, TLP3420, TLP3440, and TLP3475 come in 1.5 x 2.5 x 1.3 mm (max) VSON4 package that enables high-density assembly. While TLP3440 has improved leakage characteristics against high frequency at off-state, TLP3475 has improved high speed signal transmission characteristics at on-state. For high-voltage measurement requirements, TLP3417 supports 80 V and TLP3420 supports 100 V. All devices achieve 3 mA (max) trigger LED current and 300 Vrms (min) isolation voltage.
