HT60RP

Overview

The HT60RP is a bidirectional trigger diode (Diac) manufactured by Littelfuse Inc., designed for phase control applications. It features a breakover voltage range of 56 to 70 V and a maximum breakover current of 15 uA. The device supports a peak current of 1.5 A and operates within a temperature range of -40 C to +125 C. It is housed in a DO-35 through-hole package, suitable for high-temperature environments.

Feature Summary

• Bidirectional triggering capability for AC phase control circuits
• High thermal stability with extended operating temperature range
• Robust construction in standard axial leaded package

Applications

• Triac gate triggering
• Light dimmer circuits
• Motor speed controls

Procurement Notes

Verify the specific manufacturer source when ordering, as Littelfuse has undergone corporate restructuring involving Hamlin. Confirm RoHS compliance status and ensure the DO-35 package matches your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a precise breakover voltage between 56 V and 70 V is required for reliable triac firing. Ensure the circuit can handle the 1.5 A peak current without exceeding the thermal limits defined by the +125 C maximum junction temperature rating.

Part Context

This part belongs to the Diac/Sidac thyristor category from Littelfuse Inc. It serves as a fundamental component for triggering silicon-controlled rectifiers in power electronics. The DO-35 package provides a standardized form factor for through-hole mounting in industrial and consumer appliances.
