Overview
Description
TISP9110LDMR-S is a compact transient surge protection device (TISP) for DC power rails. It protects loads from voltage transients, short circuits, and overloads with built‑in protection logic and current‑limited output, enabling fast fault clamping and auto‑retry after a fault.
Key features (typical):
- Self-contained current limiting to cap fault current and safeguard downstream circuitry
- Overcurrent/short-circuit protection with automatic retry
- Overvoltage protection and thermal shutdown to prevent damage
- Fast response to transients
- Surface-mount LDMR‑S package for easy board integration
Applications:
- Automotive ECUs, battery-management systems, motor controllers
- DC power paths in industrial equipment, USB/PD interfaces, telecom hardware
- Any DC-rail protection where fast fault handling and recovery are needed
Note:
Exact electrical specs, pinout, package dimensions, and design guidelines are in the manufacturer’s datasheet. Consult it to select operating voltage, current limits, and layout considerations for your design.

Equivalent
I can’t reliably list equivalents without the exact function and specs. Please share the datasheet or confirm: manufacturer, intended function (transient/OV protection, high‑side switch, etc.), supply/current ratings, and package (LDMR). Do you need pin‑for‑pin cross references? If so, I’ll provide exact equivalents from TI, Onsemi, ST, NXP, Littelfuse, and Infineon.
