K2400GHAP

Overview

The Littelfuse K2400GHAP is a high-voltage trigger diode, classified as a SIDAC within the thyristor subcategory. It operates in a through-hole DO-15 package and belongs to the Kxxx0yH series. The device features a rated repetitive off-state voltage (VDRM) of 190 V and a breakover voltage (VBO) range of 220 V to 250 V. It supports an RMS on-state current (It RMS) of 1 A and can handle non-repetitive on-state currents of 16.7 A or 20 A. The component functions within a temperature range of -40°C to +85°C, with a maximum holding current of 150 mA and an on-state voltage of 1.5 V.

Feature Summary

• High-energy discharge capability for robust transient protection
• Bidirectional switching behavior suitable for AC line applications
• Through-hole construction for standard PCB mounting

Applications

• Surge protection for AC mains input circuits
• Triggering devices for silicon-controlled rectifiers (SCRs)
• Overvoltage protection in industrial control systems

Procurement Notes

Verify the specific suffix AP against the manufacturer datasheet to confirm packaging details, such as Ammo Pack versus Bulk. Ensure the order quantity aligns with factory pack sizes if specified. Cross-reference the Littelfuse part number with distributor listings to confirm availability and compliance status before finalizing procurement.

Selection Notes

Select this component when a bidirectional trigger device with a 240 V nominal breakover voltage is required. The DO-15 package suits designs needing through-hole integration. Verify that the 1 A RMS current rating meets the circuit's load requirements and that the operating temperature range covers the intended environmental conditions.

Part Context

The K2400GHAP is part of Littelfuse's Teccor SIDAC family, designed for high-energy surge suppression. It serves as a voltage-sensitive switch that remains non-conductive until the breakover threshold is reached, providing reliable protection for sensitive electronics against transient overvoltages in AC power lines.

Replacement Considerations

The K2400GH is a verified substitute part number listed in official documentation. When replacing K2400GHAP with K2400GH, verify that the packaging difference (Bulk vs. Ammo Pack) does not impact assembly processes. Electrical parameters remain consistent between these variants.
