AI summary

TSR3-24120N product

The TSR 3-24120N is a 3 A non-isolated buck regulator module that converts 15–36 VDC to 12 VDC in a SIP-3 through-hole package.

Best for

12 V point-of-load regulation
Replacing compatible TO-220 linear regulators where non-isolated conversion is acceptable
Compact through-hole industrial electronics

Avoid if

Galvanic isolation is required
The input voltage is outside 15–36 VDC
The design requires operation without thermal derating at elevated load

Check before use

Thermal derating for the selected operating conditions
Recommended external input fuse and EMC filter
Output capacitance limit
