FAQ
What is the maximum junction temperature rating for the SS8P2L-E3/86A?
The SS8P2L-E3/86A has a maximum operating junction temperature of +150 °C, validated across its full rated current range and supported by its 3.5 °C/W junction-to-lead thermal resistance. This rating allows reliable operation in sealed enclosures or high-ambient environments when mounted per the recommended 1 oz. copper pad layout. Derating curves in the SS8P2L-E3/86A datasheet confirm usable current down to –55 °C storage temperature.
Does the SS8P2L-E3/86A have a dual-anode configuration, and how is it used in circuit design?
Yes, the SS8P2L-E3/86A features two independent anode terminals (Anode 1 and Anode 2) sharing a common cathode (K). This configuration supports parallel conduction to double effective current capacity or enables interleaved converter designs where each anode serves a separate phase. The SS8P2L-E3/86A pinout ensures both anodes are electrically isolated, allowing flexible routing without internal coupling.
Is the SS8P2L-E3/86A suitable for lead-free reflow soldering processes?
Yes, the SS8P2L-E3/86A is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads meet J-STD-002 and JESD22-B102 solderability requirements, and the E3 suffix confirms RoHS compliance without requiring pre-baking or special handling prior to assembly.
What is the reverse leakage current specification for the SS8P2L-E3/86A at elevated temperature?
At VR = 30 V and TA = 125 °C, the SS8P2L-E3/86A exhibits a maximum reverse leakage current (IR) of 35 mA, as specified in its electrical characteristics table. This value reflects worst-case behavior under thermal stress and remains well within safe operating limits for low-voltage bus protection applications. At 25 °C, IR is limited to 200 µA, confirming tight process control.
How does the SS8P2L-E3/86A compare to the SS8P3L-E3/86A in terms of voltage rating and application suitability?
The SS8P2L-E3/86A is rated for 20 V VRRM, while the SS8P3L-E3/86A is rated for 30 V VRRM; all other parameters - including IF(AV), IFSM, VF, and package - are identical. Therefore, the SS8P2L-E3/86A is selected for 5–12 V systems where tighter voltage margin improves efficiency, whereas the SS8P3L-E3/86A suits 24 V auxiliary rails or designs requiring higher reverse standoff.
