Product details

Overview

SS8P6C-M3/87A from Vishay General Semiconductor is a high-current-density dual common-cathode Schottky rectifier in SMPC (TO-277A) package, rated for 60 V reverse voltage and 4 A average forward current per diode, with 0.56 V forward voltage at 4 A and 150 °C maximum junction temperature. It serves as a freewheeling or output rectifier in DC/DC converters and polarity protection circuits.

For engineers reviewing the SS8P6C-M3/87A datasheet, SS8P6C-M3/87A pinout, SS8P6C-M3/87A application, or SS8P6C-M3/87A equivalent, key selection criteria include its 60 V V_RRM, dual common-cathode configuration, low thermal resistance (R_θJL = 3 °C/W), MSL Level 1 rating, and AEC-Q101-qualified variant availability.

Technical Context

This device integrates two independent Schottky diodes sharing a single cathode terminal, enabling compact synchronous rectification or dual-path freewheeling in space-constrained power stages. Its low VF (0.56 V @ 4 A, 25 °C) and low R_θJL (3 °C/W) directly support high-efficiency, thermally demanding operation in 5–24 V input DC/DC converters.

The SMPC (TO-277A) package delivers mechanical robustness with 1.1 mm typical height, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and JESD 201 Class 2 whisker resistance - critical for automated SMT assembly and long-term reliability in industrial and automotive environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS8P5C-M3/86A	50 V V_RRM, identical package, pinout, and thermal specs	Lower voltage rating limits use to ≤36 V input systems	Select when system max reverse voltage is ≤50 V and cost optimization is prioritized
MBR860CT-E3/45	TO-220AC package, 60 V, 8 A total, higher profile (4.7 mm), R_θJA = 40 °C/W	Requires larger PCB area and heatsinking; not suitable for ultra-thin designs	Choose only if legacy TO-220 footprint compatibility or higher surge margin is required

Compared with SS8P6C-M3/87A, SS8P5C-M3/86A offers identical form factor and thermal performance but reduced voltage margin, while MBR860CT-E3/45 trades miniaturization for higher surge capability and legacy compatibility - making SS8P6C-M3/87A optimal for space-constrained, high-efficiency 48 V-class DC/DC designs.

FAQ

What is the maximum junction temperature rating for SS8P6C-M3/87A?

The SS8P6C-M3/87A has a maximum junction temperature (T_J) of +150 °C, verified per Vishay Document Number 89028. This rating enables reliable operation in sealed enclosures or high-ambient environments such as automotive engine bays or industrial control cabinets. Derating curves in Figure 1 confirm usable current capacity down to 0 A at 150 °C ambient when mounted on recommended 1 oz. copper pads.

Is SS8P6C-M3/87A pin-compatible with SS8P5C-M3/86A?

Yes, SS8P6C-M3/87A is fully pin-compatible with SS8P5C-M3/86A - both use identical SMPC (TO-277A) package, 3-pin common-cathode layout, and mechanical dimensions. The only functional difference is V_RRM: 60 V for SS8P6C-M3/87A versus 50 V for SS8P5C-M3/86A. No PCB redesign is needed when upgrading within the same voltage design margin.

Does SS8P6C-M3/87A meet automotive qualification standards?

The base SS8P6C-M3/87A is commercial-grade and RoHS-compliant, but not AEC-Q101 qualified. For automotive use, Vishay offers the SS8P6CHM3_A/H variant (with HM3 suffix), which carries full AEC-Q101 qualification and uses the same SMPC package and electrical specs. SS8P6C-M3/87A itself is suitable for non-safety-critical automotive applications where qualification is not mandated.

What is the thermal resistance from junction to lead (R_θJL) for SS8P6C-M3/87A?

The SS8P6C-M3/87A has a typical junction-to-lead thermal resistance (R_θJL) of 3 °C/W, measured per Vishay Document Number 89028. This low value reflects efficient heat conduction through the cathode tab into the PCB, enabling high-power operation without external heatsinks when using the recommended mounting pad layout with ≥1 oz. copper.

How does the forward voltage of SS8P6C-M3/87A vary with temperature?

Per Vishay's electrical characteristics table, SS8P6C-M3/87A exhibits a negative temperature coefficient for forward voltage: V_F drops from 0.56 V at 4 A and 25 °C to 0.56 V (max 0.60 V) at 4 A and 125 °C. This behavior improves conduction efficiency at elevated temperatures and supports stable parallel operation without thermal runaway.
