Overview
The Littelfuse HT32RP is a standard bidirectional DIAC trigger device manufactured by Littelfuse. It belongs to the Teccor brand thyristor family and is designed for triggering applications in AC power control circuits. The component utilizes a DO-35 axial leaded package, providing a compact form factor suitable for through-hole mounting on printed circuit boards. As a bidirectional trigger diode, it facilitates the precise firing of TRIACs and SCRs in various electronic switching and dimming applications.
Feature Summary
- Bidirectional triggering capability for symmetrical AC signal handling
- Standard breakover voltage characteristics for reliable gate triggering
- Axial leaded construction for robust mechanical mounting
Applications
- TRIAC gate triggering in light dimmer circuits
- SCR triggering in motor speed controllers
- AC phase control circuits in household appliances
Procurement Notes
Verify the specific suffix or variant code against the official Littelfuse datasheet to ensure exact electrical parameter alignment. Confirm that the DO-35 package style matches the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when a standard bidirectional trigger is required for low-power AC switching applications. Ensure the circuit design accounts for the specific breakover voltage tolerance to guarantee consistent TRIAC or SCR firing angles across varying line conditions.
Part Context
The HT32RP is part of Littelfuse's broader portfolio of power semiconductors and control ICs. It complements other devices like the HT34B within the Teccor brand lineup, serving as a fundamental building block for discrete thyristor triggering stages in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Generic equivalents such as DB3 series devices may offer functional similarity but require independent verification of breakover voltage and current ratings.
