Product Overview
Four-channel, low-capacitance TVS diode array integrating rail-to-rail steering diodes and an additional zener diode to protect I/O pins from ESD and high-surge events.
The low pF-level capacitance is suitable for high-speed I/O, but 2.4–3.0 pF to ground per I/O can still affect impedance and edge rates. ; The 15 V maximum clamp at 8 A should be evaluated against the protected IC’s pin absolute maximum rating, not merely its nominal supply voltage.

Selection Notes
Four protected channels; 6 V standoff; per-I/O capacitance; 10 A/150 W surge capability; SOT23-6 routing and pin assignment.
Coordinate VRWM with the normal signal/rail voltage and verify clamping voltage plus pulse-current/power capability for the surge waveform.
Design Considerations
-
- Verify the protected interface’s normal voltage remains below the 6 V standoff rating. 2. Check the IC absolute maximum voltage against the applicable 10/13/15 V clamp maximum. 3. Include the specified I/O-to-ground and I/O-to-I/O capacitances in SI analysis. 4. Verify the expected IEC/surge waveform does not exceed 10 A at 8/20 µs. 5. Confirm the PCB footprint and pinout correspond to the exact SRV05-4HTG, not the separately documented SRV05-4HTG-D.
Application Fit
LCD/PDP TVs, monitors, notebooks, FireWire, set-top boxes, USB ports, and 10/100/1000 Ethernet.
Exact Variant and Procurement Notes
Exact orderable SRV05-4HTG is listed as SOT23-6, marking L*4, 3,000 pieces/reel; H = SOT23-6, T = tape-and-reel, G = Green. The retrieved 2024 datasheet identifies the exact requested MPN. Do not silently substitute the separately listed SRV05-4HTG-D.
