K2200GHRP

Overview

The Littelfuse K2200GHRP is a high-voltage trigger diode, classified as a SIDAC within the thyristor product category. Manufactured by Littelfuse, this component utilizes a DO-15 through-hole package for circuit integration. It operates within a temperature range of -40°C to +85°C and carries RoHS compliance. Key electrical specifications include a breakover voltage (VBO) ranging from 205 V to 230 V and a rated repetitive off-state voltage (VDRM) of 180 V. The device supports an RMS on-state current (It RMS) of 1 A and features a maximum holding current (Ih) of 150 mA. Non-repetitive on-state current ratings are specified at 16.7 A or 20 A, with an on-state voltage of 1.5 V.

Feature Summary

• High-voltage triggering capability for precise circuit activation
• Robust construction in a standard through-hole DO-15 package
• Designed for reliable operation across wide industrial temperature ranges

Applications

• Triggering circuits for silicon-controlled rectifiers (SCRs)
• Protection stages in AC power control systems
• Gate drive networks for thyristor-based converters

Procurement Notes

Verify the specific suffix 'HRP' against official Littelfuse documentation to confirm packaging details, as distributor listings may vary. Ensure the selected variant matches the required breakover voltage tolerance and thermal rating for the target application environment. Cross-reference the manufacturer part number directly with the datasheet to avoid substitution errors.

Selection Notes

Select this component when a bidirectional trigger device with a defined breakover voltage between 205 V and 230 V is required. Consider the 1 A RMS current rating and DO-15 package size for board space constraints. Verify that the 180 V repetitive off-state voltage aligns with the peak circuit voltage to prevent unintended triggering during normal operation.

Part Context

The K2200G series belongs to Littelfuse's family of high-voltage trigger diodes, commonly referred to as SIDACs. These devices are symmetric bidirectional components designed to switch rapidly once a threshold voltage is exceeded. The K2200GHRP variant specifically denotes the commercial grade version packaged in bulk, distinct from tape-and-reel configurations.

Replacement Considerations

Consult Littelfuse official cross-reference guides for verified substitutes. Generic equivalents may differ in holding current or breakover voltage tolerances. Do not assume pin-compatible replacements without verifying electrical parameters against the original datasheet.

FAQ

What is the difference between VBO and VDRM for the K2200GHRP?

VBO (Breakover Voltage) is the voltage at which the device switches to the low-resistance state, ranging from 205 V to 230 V. VDRM (Rated Repetitive Off-State Voltage) is the maximum voltage the device can withstand in the off-state without triggering, specified at 180 V.

Is the K2200GHRP unidirectional or bidirectional?

The K2200GHRP is a bidirectional trigger diode, meaning it functions identically regardless of the polarity of the applied voltage across its terminals.

What package type does the K2200GHRP use?

The component is housed in a DO-15 axial leaded package, suitable for through-hole mounting on printed circuit boards.
