HT8-214

HENGTUO ELECTRONICS · Solid State Relays (MOS Output) · DIP-8

HT8-214 from HENGTUO ELECTRONICS, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 AN1 input Channel 1 LED anode. Input-side AlGaAs infrared LED anode; drive with I_F up to 50 mA (V_F typ. 1.2 V at 10 mA) to activate the channel-1 output MOSFETs.
2 CA1 input Channel 1 LED cathode. Return path for the channel-1 input LED current.
3 AN2 input Channel 2 LED anode. Input-side AlGaAs infrared LED anode for the second SSR channel.
4 CA2 input Channel 2 LED cathode. Return path for the channel-2 input LED current.
5 DRAIN2A passive Channel 2 output MOSFET drain. One terminal of the channel-2 AC/DC switch; rated 400 V blocking, 120 mA continuous, ~20 Ω R_ds(on) typ.
6 DRAIN2B passive Channel 2 output MOSFET drain (opposite polarity). Second terminal of the channel-2 back-to-back MOSFET switch, forming the Form-A contact with pin 5.
7 DRAIN1A passive Channel 1 output MOSFET drain. One terminal of the channel-1 AC/DC switch; rated 400 V blocking, 120 mA continuous, ~20 Ω R_ds(on) typ.
8 DRAIN1B passive Channel 1 output MOSFET drain (opposite polarity). Second terminal of the channel-1 back-to-back MOSFET switch, forming the Form-A contact with pin 7.
