CNY17F2TVM

Overview

The CNY17F2TVM is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output and utilizes a PDIP-6 through-hole package. Key electrical parameters include an insulation voltage of 4170 Vrms, a collector-emitter voltage of 70 V, and a maximum collector current of 50 mA. The device operates with a forward current of 60 mA and exhibits a forward voltage of 1.65 V. Current transfer ratio ranges from 63% to 125%. Timing characteristics specify a rise time of 6 µs and a fall time of 24 µs. Power dissipation is rated at 270 mW, with an operating temperature range spanning from -40°C to +100°C.

Feature Summary

• Provides galvanic isolation between input and output circuits via an infrared LED and phototransistor pair.
• Features a standard six-pin DIP configuration suitable for through-hole mounting on printed circuit boards.
• Delivers high insulation voltage capability to ensure safety in isolated signal transmission applications.

Applications

• General-purpose signal isolation in industrial control systems
• Microprocessor system interface circuits requiring noise immunity
• Power supply feedback loops for voltage regulation

Procurement Notes

Verify the specific suffix TVM corresponds to the bulk packaging format as documented by onsemi. Confirm that the PDIP-6 package dimensions align with your PCB footprint requirements. Ensure the 4170 Vrms insulation rating meets the safety standards applicable to your target equipment classification. Cross-reference the current transfer ratio specifications against your circuit design margins to guarantee reliable switching performance under varying temperature conditions.

Selection Notes

Select this component when a robust, cost-effective solution for low-speed digital isolation is required. The NPN phototransistor output is compatible with standard logic families. Consider the 6 µs rise time limitation; it is unsuitable for high-frequency data transmission but adequate for general switching tasks. The wide operating temperature range supports deployment in harsh environmental conditions common in industrial settings.

Part Context

This part belongs to the CNY17F2M series of transistor output optocouplers. The series is designed for general-purpose isolation applications where reliability and standard packaging are prioritized. The CNY17F2TVM variant specifically denotes the through-hole DIP configuration, distinguishing it from surface-mount alternatives within the same functional family offered by onsemi.

Replacement Considerations

Direct pin-compatible substitutes may include other CNY17 series variants with different speed orCTR ratings, provided the insulation voltage and package type remain consistent. Verify that any alternative maintains the 70 V collector-emitter voltage and 50 mA current limits to ensure circuit integrity without redesigning the surrounding components.
