L293DD013TR

The L293DD013TR is the tape-and-reel SO-20 code for the STMicroelectronics L293D quadruple half-H driver. Each channel delivers 600 mA with 1.2 A non-repetitive peaks across a 4.5 V to 36 V load supply, channels pair into two full bridges for DC or bipolar stepper motors, and internal clamp diodes plus overtemperature protection are built in. The surface-mount SO-20 body is the selection point against the through-hole L293D: the same proven drive stage goes onto automated SMT lines for printer, POS, vending and small-actuator products without a board-level redesign of the power stage. Selection advice: quote the full 013TR code, because L293 variants in DIP-16 and PowerSO packages share the family name but not the footprint; design copper for the SO-20 thermal path, since continuous current is set by board dissipation, not the 1.2 A peak figure. Parameters verified against STMicroelectronics documentation.
