K1500E70RP

Overview

The Littelfuse K1500E70RP is a high-voltage bidirectional trigger diode, classified as a SIDAC within the Teccor Kxxxzy series. It is housed in a TO-92 through-hole package and features glass-passivated junctions for ruggedness. The device operates as a silicon bilateral voltage-triggered switch, conducting current once the applied voltage exceeds its breakover threshold. Key electrical parameters include a nominal breakover voltage of 150V, with a maximum rating of 165V. It supports a non-repetitive peak current of 20A and has a rated holding current of 60A.

Feature Summary

• Silicon bilateral voltage-triggered switching mechanism
• Glass-passivated junction construction for environmental durability
• Negative resistance region operation for low on-state voltage

Applications

• High voltage power supplies
• Natural gas igniters
• High-pressure Sodium lamps
• Xenon flash ignition systems

Procurement Notes

Verify the specific suffix 'RP' against the manufacturer's official documentation to confirm packaging details, such as reel specifications or tape-and-reel quantities. Ensure the component meets RoHS compliance requirements for the intended manufacturing process. Cross-reference the datasheet revision date to validate the accuracy of the electrical characteristics provided.

Selection Notes

Select this component when a robust, high-voltage trigger switch is required for AC circuits. The TO-92 package suits through-hole mounting applications. Verify that the circuit design accommodates the 150V breakover threshold and the 60A holding current requirement to ensure reliable latching and turn-off behavior during operation.

Part Context

This part belongs to the Littelfuse Teccor Kxxxzy SIDAC family. These devices are standard bidirectional trigger diodes designed for high-voltage switching applications. The series utilizes glass-passivated junctions to withstand harsh environments, distinguishing them from lower-rated semiconductor switches.

Replacement Considerations

Substitutes within the same series include K1400E70RP (140V) and K1800E70RP (180V). Selection depends on matching the specific breakover voltage requirements of the target circuit application.
