Product Description:

The SS52, member of the Slo-Syn Synchronous Motors family by Danaher, includes voltage range of 20 to 100 volts. This commercial unit suits applications needing stable rectification across varied DC input levels. As a surface mount barrier rectifier, it offers low forward voltage drops to ensure high-speed switching in compact assemblies. Its maximum repetitive peak reverse voltage is 20 volts, protecting the system from unintended current reversal during normal circuit oscillations. The 14-volt maximum RMS voltage further supports lower thermal buildup.

Carrying a maximum DC blocking voltage of 20 volts, the module prevents reverse current flow which preserves load-side circuitry. A continuous forward rectified current rating of 5.0 amperes enables robust current conduction during extended active states. The device withstands a peak forward surge current of 100 amperes as per the Suntan datasheet while Taitron lists it at 150 amperes. The 0.55-volt forward voltage drop at 1.0A minimizes energy loss during conduction and hence reduces efficiency drag under load. A maximum reverse leakage current of just 0.5 mA at 25°C limits parasitic drain that preserve voltage levels across passive loads.

The thermal resistance from junction-to-ambient is 55 °C/W per Suntan and 40 °C/W per Taitron, making passive cooling viable for most applications. The junction-to-lead resistance is 12 °C/W and 10 °C/W respectively which enables better heat conduction through solder paths during operation. Operating junction temperature spans from -55°C to +150°C and the storage temperature also ranges from -55 °C to +150 °C, thus protecting the motor from thermal damage during shipment or standby. The synchronous SS52 motor supports a junction capacitance of 150 pF, enabling faster signal handling and rectification speeds. Reverse recovery time is just 5 ns with a benefit of high-frequency power conversion in compact systems.
