The HD0680D is rated at 80A, the HD06100D at 100A, the HD06120D at 120A, and the HD06150D at 150A. All models share the same 24VDC control input and DC load voltage rating. Choose the model that, after applying the appropriate safety margin (2–2.5× for resistive loads, 6–7× for inductive loads), meets or exceeds your application's actual current requirements.\u003c\/p\u003e\n\u003ch4\u003eQ: Do I need a heat sink with this industrial solid state relay?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — a heat sink is strongly recommended and required whenever the actual operating current exceeds 5A. Without adequate heat dissipation, the module can overheat and fail prematurely. Always size the heat sink appropriately for your current load and ambient temperature to ensure reliable, long-term operation.\u003c\/p\u003e\n\u003ch4\u003eQ: Can this DC solid state relay be used with inductive loads like motors or solenoids?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, but with an important precaution: a freewheeling diode must be connected in reverse-parallel across the load terminals when driving inductive loads. This protects the relay module from the reverse voltage spike (back-EMF) produced when the inductive load is switched off. Suitable diodes include the ZP50A\/58 or ZP100A\/58. Omitting this component can prevent the relay from switching off correctly and may permanently damage the module.\u003c\/p\u003e\n\u003ch4\u003eQ: Is bulk ordering available for the SSR HD06 series solid state relays?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
