Product details

What 5000Vrms isolation means for your galvanic barrier

Rated at 5000Vrms, this dual-channel optocoupler provides reinforced isolation between the DC input side and the transistor output. That rating supports IEC 60950-1 reinforced insulation for mains-isolated interfaces — think PLC digital inputs, motor-drive feedback, or any industrial communication link where ground potential differences could otherwise damage the logic side.

CTR floor and output current budget

Current transfer ratio spans 19% minimum to 50% maximum at a forward current of 16 mA. With a maximum output current of 8 mA per channel, the CTR minimum dictates the input drive: at 19% CTR, 8 mA output demands 42 mA forward current — which exceeds the 25 mA absolute maximum forward current. Practical designs must either limit output load or increase CTR headroom by operating above 16 mA IF, staying within the 25 mA ceiling. The 250 ns turn-on and 260 ns turn-off times keep the part viable for data rates up to roughly 2 Mbps, with the 10 ns skew between edges preserving pulse-width fidelity.

Package and temperature range for the board

Housed in an 8-SMD gull wing package, the HCPL2531SVM mounts on the surface — no through-hole soldering.

What is the difference between HCPL2531SVM and HCPL2531?

The HCPL2531SVM is the surface-mount variant (8-SMD gull wing,) of the base HCPL2531, which is a through-hole DIP-8 package. All other electrical ratings — 5000Vrms isolation, 19-50% CTR, 250ns switching — are identical between the two order codes. The 'SVM' suffix specifically denotes the gull-wing surface-mount option.
