The SLD series is specifically designed for automotive applications, available in both unidirectional and bidirectional. The SLD 10U is designed to be used in series, for example three 10Us in series for a 30 volt working; this configuration will provide a very high power (a multiple of 3) capability and is a far superior solution than using devices in parallel, which will require closely matched devices in order to prevent ‘current hogging’ and consequently, damage to the device.
The SLD Series silicon avalanche diodes are high‑power, axial‑lead automotive transient voltage suppressors offered in unidirectional and bidirectional versions. They are designed for use in series to achieve higher working voltages and provide superior protection compared with parallel configurations.
Key data include peak pulse power ratings of 2,200 W (100/150 µs) and 50,000 W (8/20 µs), steady‑state dissipation of 6.3 W, and a maximum instantaneous forward voltage of 3.5 V at 100 A. The devices are RoHS compliant, UL94V‑0 flame‑rated, and available in tape‑and‑reel (800 pcs) or P600 case packaging.
