4N37TVM

Transistor, Photovoltaic Output Optoisolators Overview

The onsemi 4N37TVM is a single-channel optoisolator featuring a transistor output with a base terminal, housed in a 6-DIP package. It provides an isolation voltage of 4170Vrms and supports a DC input type. Key electrical parameters include a maximum forward current (If) of 60 mA, a typical forward voltage (Vf) of 1.18V, and a collector-emitter saturation voltage (Vce(sat)) of 300mV max at 30V. The device offers a minimum current transfer ratio of 100% at 10mA input. Switching characteristics are defined by typical turn-on and turn-off times of 2µs each. It operates within a temperature range of -40°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix 'TVM' corresponds to the tube packaging configuration as indicated in official documentation. Confirm RoHS compliance status and REACH declaration details directly from the manufacturer's latest material declaration documents prior to procurement. Ensure the selected component matches the required 6-DIP through-hole package dimensions for PCB layout compatibility.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a transistor output optocoupler with a base terminal is required for circuit design flexibility. Consider the 4170Vrms isolation rating for applications demanding high voltage separation between input and output sides. Evaluate the 2µs switching speed against system timing requirements. Verify that the 60mA maximum forward current and 100% CTR at 10mA meet the drive conditions of the specific application circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

The 4N37TVM belongs to the 4N37M series of optoisolators manufactured by onsemi. This series is widely recognized for its reliability in general-purpose isolation applications. The 'TVM' suffix typically denotes specific packaging or tape-and-reel variations within the broader 4N37 family, distinguishing it from other variants like the standard 4N37 or 4N35.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements may include other 4N37 series variants such as 4N37 or 4N37M, provided pinout and electrical specifications match. Cross-reference with similar transistor-output optocouplers from other manufacturers only if isolation voltage, CTR, and switching speeds are equivalent. Verify package compatibility before substitution.
