K2200E70RP3

Overview

The Littelfuse K2200E70RP3 is a silicon bilateral voltage-triggered switch (SIDAC) from the Kxxxzy series, housed in a TO-92 package. It features a breakover voltage range of 205V to 230V and a repetitive peak off-state voltage of 180V. The device supports an on-state RMS current of 1A at 50/60Hz with a junction temperature below 125°C. Key electrical parameters include a peak on-state voltage of 1.5V at 1A, a dynamic holding current between 10mA and 150mA, and a peak non-repetitive surge current of 16.7A for a single cycle at 50Hz. Thermal resistance from junction to ambient is 95°C/W.

Feature Summary

• Silicon bilateral voltage triggered switch utilizing glass-passivated junctions for ruggedness
• Switches on through a negative resistance region to a low on-state voltage upon exceeding breakover point
• RoHS compliant construction with matte tin plated terminals

Applications

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

Procurement Notes

Verify the specific ordering suffix RP3 corresponds to the Reel Pack configuration for the TO-92 package as documented in the packing options table. Confirm that the base quantity aligns with the specified reel capacity of 2000 units. Ensure compatibility with standard surface mount or through-hole assembly processes depending on the final circuit design requirements.

Selection Notes

Select this component when a bidirectional trigger device with a breakover voltage between 205V and 230V is required. The TO-92 package offers radial leads suitable for through-hole mounting. Consider the 1A RMS current rating and thermal characteristics for applications involving continuous sinusoidal currents. Verify that the operating environment stays within the -40°C to 125°C junction temperature range.

Part Context

This part belongs to the Littelfuse Kxxxzy Series of Standard Bidirectional SIDACs. The 'K' denotes the SIDAC device type, '220' indicates the voltage rating class, '0' specifies the standard circuit function, 'E' identifies the TO-92 package, '70' refers to the lead form dimensions, and 'RP3' indicates the reel packaging option for TO-92 components.

Replacement Considerations

Other parts in the Kxxxzy series with different voltage ratings such as K2000E70 or K2300E70 may serve as alternatives if the breakover voltage requirements differ. Ensure any substitute maintains the same TO-92 package and electrical characteristics relevant to the specific application constraints.
