| Littelfuse Spice Models |
| Using SPICE Models is the industry standard way to simulate circuit performance prior to the prototype stage as an additional step of testing to ensure that your circuit works properly before investing in prototype development. The models provided here were developed (or revised) using WinSpice, a port of Berkeley Spice3F4 to Win32, and should be compatible with most SPICE2 or SPICE3-based circuit simulators (such as PSPICE). | | View More Littelfuse Technical Resources |

Littelfuse SMA Series SIDACs - EXPANSION
Littelfuse expanded its Littelfuse SIDACtor Baseband Protection Thyristors product line to include the low profile SMA Series. The SMA Series features excellent surge rating, low voltage overshoot, and low capacitance with a smaller SMA package. The SMA Series from Littelfuse does not degrade surge capability after multiple events and is ideal for cordless and digital phones that require CPE Tip to Ring Protection, Telecom line protection.
Littelfuse SIDACtor Baseband Protection Thyristors are solid state crowbar
devices designed to protect of baseband telecommunications equipment
such as phones, faxes, modems, line cards, CPE and DSL from damaging
overvoltage transients. Leveraging the latest in thyristor advancements,
Littelfuse offers SIDACtor devices with a patented ion implant
technology. This technology ensures effective protection within
nanoseconds, up to 3000 A 1.2-50-8/20 surge current ratings, and simple
solutions for regulatory requirements such as GR 1089, TIA-968-B
(formerly known as FCC Part 68), ITU-T K.20, ITU-T K.21, and UL 60950-1.
In the standby mode, SIDACtor devices exhibit a high off-state
impedance, eliminating excessive leakage currents and appearing transparent to the circuits they
protect. If a voltage exceeding the switching voltage (VS) occurs, the
SIDACtor devices crowbar and simulate a short circuit condition until
the current flowing through the device is either interrupted or drops
below the SIDACtor device's holding current (IH). When this occurs,
SIDACtor devices reset and return to their high off-state impedance.
