Product Overview
Littelfuse MLA multilayer varistor (MLV), leadless surface-mount transient-voltage suppressor; bidirectional clamping. Exact V5.5MLA0603NH is listed in Littelfuse’s official product resources.
Suitable for low-voltage board-level transient/ESD suppression, but its relatively high capacitance should be checked on high-speed or impedance-sensitive nodes. The leadless construction and sub-1-ns dielectric response support fast transient suppression when placed close to the protected circuit.

Selection Notes
working voltage; clamp voltage; surge current/energy; capacitance; 0603 PCB area and reel format.
Keep continuous operating voltage below the applicable rating and check varistor/clamping levels against both the protected node and expected surge.
Manufacturer Decision-Relevant Notes
VM(DC) 5 V; VM(AC) 4 V RMS; VN(DC) 7.1–9.3 V at 1 mA; VC 17.5 V at 1 A, 8/20 µs; ITM 30 A, 8/20 µs; WTM 0.1 J, 10/1000 µs; typical capacitance 960 pF at 1 MHz; operating temperature -40 to +125 °C.
Design Considerations
- Verify normal DC never exceeds 5 V; verify protected IC absolute maximum exceeds the actual clamped waveform, including layout inductance; verify the event current is ≤30 A for the stated 8/20-µs rating; check 960-pF loading at 1 MHz; confirm 0603 land pattern and 7-inch-reel assembly requirements.
Application Fit
ESD, EFT, inductive-switching and board-level transient protection; EMC support; IC/transistor protection.
Exact Variant and Procurement Notes
0603 = 1.6 × 0.8 mm EIA package; N = nickel barrier; H = 7-inch reel packing, 2,500 pieces. NH is listed with RoHS/REACH documentation.

Quality & Verification Support
Third-party inspection or testing can be arranged according to customer requirements. Testing fees are borne by the buyer. Additional verification requirements can be discussed before shipment. Physical product, label, packaging, and Date Code photos may be provided where appropriate.
Request a Quote
For V5.5MLA0603NH quotation, provide the exact MPN, required quantity, destination, target Date Code if applicable, and any inspection or testing requirements.
For a smaller-footprint 5.5 V-class MLA varistor, compare Littelfuse V5.5MLA0402NR (0402, paper-tape reel). Its typical 1 MHz capacitance is 220 pF and rated 8/20 µs peak surge current is 20 A, versus 960 pF and 30 A for this 0603 device; the energy ratings also differ (0.05 J versus 0.1 J). Confirm clamping limits and PCB footprint before selection.
