Product details
Overview
SS8PH10-E3/86A from Vishay General Semiconductor is a high-voltage Schottky rectifier in TO-277A (SMPC) package, rated for 100 V repetitive peak reverse voltage, 8.0 A average forward current, and 150 A surge capability. It features low forward voltage (0.720 V at 8 A, 125 °C), ultra-low leakage (0.18 µA at 25 °C), and operates up to 175 °C junction temperature - deployed in DC-DC converters and polarity protection circuits.
For engineers reviewing the SS8PH10-E3/86A datasheet, SS8PH10-E3/86A pinout, SS8PH10-E3/86A application, or SS8PH10-E3/86A equivalent, key selection criteria include its 100 V VRRM, 0.720 V VF @ 8 A / 125 °C, 20 mJ non-repetitive avalanche energy, TO-277A thermal resistance (RθJA = 65 °C/W), and AEC-Q101 qualification eligibility via HE3/HM3 variants.
Technical Context
This Schottky rectifier uses high-barrier technology to achieve stable operation at TJ = 175 °C while maintaining low leakage and low forward voltage. Its guardring structure provides overvoltage protection, and the eSMP™ package enables automated placement with 1.1 mm typical height.
Designed for high-frequency switching applications, it delivers fast recovery (no minority carrier storage), low junction capacitance (140 pF @ 4 V, 1 MHz), and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS8PH9-E3/86A | 90 V VRRM, identical package, pinout, and thermal specs | Suitable where 90 V rating suffices; lower voltage margin than SS8PH10-E3/86A | Select SS8PH9-E3/86A only if system max reverse voltage ≤ 90 V and cost optimization is prioritized |
| ON Semiconductor SB8100E3/86A | 100 V VRRM, 8 A IF(AV), but higher VF (0.82 V @ 8 A, 125 °C) and no guardring | Lacks overvoltage ruggedness; less suitable for transient-prone automotive or industrial inputs | Prefer SS8PH10-E3/86A where low conduction loss and transient immunity are critical |

FAQ
What is the maximum junction temperature rating for SS8PH10-E3/86A?
The SS8PH10-E3/86A has a maximum operating junction temperature of +175 °C, enabled by high-barrier Schottky technology. This allows reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations. Derating curves in the datasheet (Fig. 1) define safe current limits versus case or lead temperature. The SS8PH10-E3/86A must be mounted on the recommended 1 oz. copper PCB pad layout to achieve thermal performance consistent with this rating.
Does SS8PH10-E3/86A have a guardring, and what function does it serve?
Yes, the SS8PH10-E3/86A incorporates a guardring structure explicitly stated in its features list. This guardring enhances overvoltage protection by controlling electric field distribution at the silicon edge, improving ruggedness against transient voltage spikes and reducing risk of premature breakdown. It is especially valuable in applications exposed to load dump or inductive switching events - such as automotive body control modules or industrial motor drives - where the SS8PH10-E3/86A serves as a primary protection element.
What is the forward voltage of SS8PH10-E3/86A at 8 A and 125 °C?
The SS8PH10-E3/86A exhibits a typical forward voltage of 0.720 V at 8 A and 125 °C, as specified in the Electrical Characteristics table. This value reflects real-world conduction loss under elevated thermal conditions and is critical for calculating power dissipation and efficiency in high-temperature DC-DC converter designs. At 25 °C and 8 A, VF is higher (0.850 V max), confirming the device's favorable thermal coefficient - a key advantage of its high-barrier architecture.
Is SS8PH10-E3/86A suitable for lead-free reflow assembly?
Yes, the SS8PH10-E3/86A meets J-STD-020 MSL Level 1 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering processes. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102 for solderability, and the E3 suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance. No pre-baking is required prior to reflow, simplifying manufacturing flow for the SS8PH10-E3/86A.
How does the TO-277A package of SS8PH10-E3/86A impact thermal performance?
The TO-277A (SMPC) package of the SS8PH10-E3/86A provides a typical junction-to-ambient thermal resistance (RθJA) of 65 °C/W when mounted on the recommended 1 oz. copper PCB pad layout. Its low 1.1 mm profile maximizes board-level heat spreading while minimizing vertical clearance. Unlike traditional SMA packages, TO-277A uses dual anode terminals and a large cathode pad to enhance current handling and thermal conduction - directly supporting the SS8PH10-E3/86A's 8 A continuous rating without external heatsinking in many applications.
