The 5300 Vrms isolation rating covers reinforced insulation requirements for mains-connected equipment, and the 1.5 kV/µs minimum static dV/dt ensures the output stays off during fast line transients — important for noisy industrial environments. The output is non-zero-crossing (random-phase), so the triac fires on any phase angle of the AC waveform, making this part suitable for phase-control applications like resistive load dimming or soft-start, not just on/off switching. ## 5 mA LED trigger — direct drive from logic or MCU The LED forward voltage is 1.2 V typical, and the maximum continuous forward current is 60 mA, giving plenty of margin for derating at elevated temperatures or for driving the LED harder to reduce turn-on propagation delay. The on-state output current is rated at 100 mA RMS maximum, sized for driving a power triac gate or a small load directly. ## Active lifecycle, ROHS3, cUR/UR approvals It is ROHS3 compliant and holds cUR and UR component recognition, covering North American safety agency requirements for isolation components.","metaTitle":"VO3053 Triac Optocoupler, 600 V Off-State, 5.3 kV Isolation","metaDescription":"VO3053 triac output optocoupler: 600 V off-state, 5300 Vrms isolation, 1.5 kV/µs dV/dt, non-zero-cross, 5 mA IFT, -55°C to 100°C, 6-DIP.

Both are non-zero-crossing, 6-DIP, 5.3 kV isolation parts. The 600 V rating of the VO3053 gives more headroom for 240 VAC line applications or for designs that need margin against line surges."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/VO3053","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/VO3053 when reusing this data.
