Product details
Overview
SS8PH10-M3/87A from Vishay General Semiconductor is a high-current-density, high-voltage Schottky rectifier in SMPC (TO-277A) package, rated for 100 V repetitive peak reverse voltage, 8.0 A average forward current, and 150 A non-repetitive surge current. It delivers 0.720 V forward voltage at 8.0 A and 25 °C, with only 0.18 μA reverse leakage, enabling efficient DC/DC conversion in space-constrained power supplies.
For engineers reviewing the SS8PH10-M3/87A datasheet, SS8PH10-M3/87A pinout, SS8PH10-M3/87A application, or SS8PH10-M3/87A equivalent, key selection criteria include its 100 V VRRM, 175 °C maximum junction temperature, AEC-Q101 qualification eligibility (via HM3 suffix), low-profile 1.1 mm height, and MSL Level 1 moisture sensitivity rating.
Technical Context
This device uses high-barrier Schottky technology to achieve stable operation up to 175 °C junction temperature while maintaining low forward voltage and ultra-low leakage. Its guardring structure provides overvoltage protection, and the SMPC package enables automated placement with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
The SS8PH10-M3/87A is a single-anode, single-cathode configuration with two anode terminals (pins 1 and 2) tied internally and one common cathode (pin 3). Thermal resistance is 65 °C/W junction-to-ambient on recommended 1 oz. copper pad layout, supporting high-power density designs without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input rails up to 85 V DC in offline SMPS or 48 V industrial bus systems with margin |
| IF(AV) | 8.0 A - sustains continuous output current in compact 50–100 W DC/DC converters |
| VF @ 8.0 A | 0.720 V - reduces conduction loss to ~5.8 W per diode, minimizing thermal load in high-efficiency designs |
| IR @ 25 °C | 0.18 μA - ensures negligible standby power loss in battery-backed or energy-sensitive applications |
| TJ max | 175 °C - enables operation in under-hood automotive or sealed industrial enclosures without derating |
| EAS | 20 mJ - withstands inductive switching transients in freewheeling paths without avalanche failure |
| CJ | 140 pF @ 4 V - limits capacitive switching loss and EMI generation in >100 kHz converter topologies |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal, 1.1 mm typical height, UL 94 V-0 molding compound, halogen-free and RoHS-compliant.

IC Role / Device Role / Timing Role: Input rectifier and overvoltage clamp in buck-derived front-end with transient suppression. Use Value: Guardring design and AEC-Q101-qualified variant compatibility (SS8PH10HM3_A) ensure robustness against load-dump spikes up to ±100 V. | Use Scenario: Reverse-polarity protection diode in IEEE 802.3at (PoE+) powered device interface, placed before DC-DC controller. IC Role / Device Role / Timing Role: Unidirectional blocking element preventing damage during hot-swap or miswiring events. Use Value: 0.18 μA IR at 25 °C minimizes quiescent current drain on 57 V PoE input, preserving >99.9 % of available power budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS8PH10HM3_A | AEC-Q101 qualified; same electrical specs; HM3 suffix denotes automotive qualification and revision code "A" | Required for automotive production; supports PPAP documentation and extended temperature validation | Select SS8PH10HM3_A when automotive-grade traceability, qualification, and long-term supply assurance are mandatory |
| ON Semiconductor SB8100 | Same 100 V VRRM, 8 A IF(AV), but higher VF (0.82 V @ 8 A); TO-277 package (not TO-277A); no guardring | Lacks overvoltage ruggedness; less suitable for unregulated or noisy input rails | Choose SB8100 only if cost is primary driver and system-level surge testing confirms adequate margin without guardring |
Compared with SS8PH10HM3_A, the SS8PH10-M3/87A offers identical performance in commercial environments but lacks automotive qualification documentation; versus SB8100, it delivers lower conduction loss and superior transient robustness-critical in high-reliability 48 V and PoE+ systems.

FAQ
What is the maximum junction temperature rating for SS8PH10-M3/87A?
The SS8PH10-M3/87A has a maximum junction temperature (TJ) of +175 °C, verified per Vishay's datasheet revision 24-Apr-2020. This allows uninterrupted operation in high-ambient environments such as enclosed industrial drives or under-hood automotive electronics. Derating curves in Figure 1 confirm usable current down to -55 °C, making SS8PH10-M3/87A suitable for wide-temperature deployments without thermal throttling.
Is SS8PH10-M3/87A pin-compatible with SS8PH9-M3/87A?
Yes, SS8PH10-M3/87A and SS8PH9-M3/87A share identical SMPC (TO-277A) package dimensions, pinout, and terminal configuration - both feature dual anodes (pins 1 and 2) and a common cathode (pin 3). The only difference is VRRM: 100 V for SS8PH10-M3/87A versus 90 V for SS8PH9-M3/87A. Layout reuse is fully supported; no PCB changes are needed when upgrading from SS8PH9-M3/87A to SS8PH10-M3/87A.
Does SS8PH10-M3/87A meet automotive qualification standards?
The SS8PH10-M3/87A itself is commercial-grade (M3 suffix), not AEC-Q101 qualified. However, Vishay offers the functionally identical SS8PH10HM3_A variant - same electrical specs and SMPC package - which carries full AEC-Q101 qualification. For automotive production, specify SS8PH10HM3_A; SS8PH10-M3/87A remains appropriate for industrial, computing, and telecom applications where automotive certification is not required.
What is the thermal resistance of SS8PH10-M3/87A under standard mounting conditions?
Per the Vishay datasheet, SS8PH10-M3/87A exhibits a typical junction-to-ambient thermal resistance (RθJA) of 65 °C/W when mounted on the recommended 1 oz. copper PCB pad layout. This value assumes natural convection and no added heatsink. Junction-to-lead (RθJL) is 3 °C/W, confirming strong thermal coupling to the cathode pad - critical for optimizing power dissipation in high-current layouts.
How does the guardring in SS8PH10-M3/87A improve system reliability?
The integrated guardring in SS8PH10-M3/87A prevents premature edge breakdown during voltage transients, significantly enhancing ruggedness against line surges, inductive kickback, and load-dump events. In practice, this allows SS8PH10-M3/87A to sustain 20 mJ non-repetitive avalanche energy (EAS) without failure - a key differentiator versus non-guardring Schottkys. This directly extends field lifetime in DC/DC converters exposed to unstable input sources.
