Product details
Overview
STPS560SFY from STMicroelectronics is an AEC-Q101-qualified 60 V, 5 A automotive power Schottky rectifier in PSMC (TO-277A) package, featuring 0.43 V typical forward voltage at 5 A and 125 °C, 175 °C maximum junction temperature, and wettable flanks for automated optical inspection-used in DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the STPS560SFY datasheet, STPS560SFY pinout, STPS560SFY application, or STPS560SFY equivalent, key selection criteria include avalanche capability (258 W peak), thermal resistance (2.0 °C/W junction-to-case), reverse leakage (25 mA at 125 °C), and automotive-grade reliability under -40 °C to +175 °C operating range.
Technical Context
This Schottky rectifier uses a planar metal-silicon junction optimized for low conduction loss and high-temperature stability. Its 60 V repetitive peak reverse voltage is guaranteed across -40 °C to +175 °C, and it delivers 230 A non-repetitive surge current with 10 ms sinusoidal pulse width.
The device integrates avalanche energy handling (258 W at 10 µs, Tj = 125 °C) and exhibits low thermal impedance-Rth(j-c) = 2.0 °C/W-enabling compact thermal design in space-constrained automotive modules without external heatsinking at moderate power levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 5 A average forward current at Tc = 160 °C - supports continuous operation in high-power automotive DC/DC stages |
| VRRM | 60 V repetitive peak reverse voltage - rated for 48 V system transients and load-dump immunity |
| VF (typ.) | 0.43 V at IF = 5 A, Tj = 125 °C - minimizes conduction loss and thermal stress in high-efficiency converters |
| Tj (max.) | 175 °C - enables placement near hot engine-control units without derating |
| Rth(j-c) | 2.0 °C/W - allows direct PCB copper pad conduction cooling without mechanical heatsink |
| IR (max.) | 25 mA at VR = VRRM, Tj = 125 °C - limits standby power loss in always-on vehicle systems |
| PARM | 258 W peak avalanche power at tp = 10 µs - protects against inductive switching spikes in motor drivers |
Pinout & Package
STPS560SFY is housed in a surface-mount PSMC (TO-277A) package with two anode terminals and one cathode terminal. The package features wettable flanks for solder-joint inspection and is optimized for thermal conduction via the exposed cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Forward current input | Parallel-connected anode terminal; shares current path with Anode 2 to reduce effective series resistance |
| Anode 2 | Forward current input | Second anode terminal electrically identical to Anode 1; enables higher current handling and lower VF |
| Cathode | Forward current output / heat sink interface | Exposed metal tab serving as both electrical return and primary thermal path to PCB copper area |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood use including temperature cycling, humidity, and mechanical shock per JESD47 |
| Avalanche capability | 258 W peak power at 10 µs pulse enables robustness against inductive turn-off transients without snubbers |
| Wettable flanks | Side-plated terminals allow automated optical inspection (AOI) of solder fillets on SMT assembly lines |
| ECOPACK®2 compliance | Lead-free, halogen-free, RoHS-compliant construction meeting automotive environmental standards |
| High Tj rating | 175 °C max junction temperature permits operation adjacent to power MOSFETs or ignition coils |
Applications
| DC/DC Converters | Reverse Polarity Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-50SQ060 | Same 60 V/5 A rating but TO-252 (DPAK) package; Rth(j-c) = 3.0 °C/W; no wettable flanks | Lacks AEC-Q101 qualification and automotive PPAP support; not validated for underhood thermal cycling | Preferred for cost-sensitive industrial supplies where AOI and automotive qualification are not required |
| ON Semiconductor SB560-E3/54 | 60 V/5 A, DO-201AD package; VF = 0.72 V (typ.) at 5 A; Tj(max) = 125 °C | Higher VF increases conduction loss by ~65%; limited to cabin-located modules due to lower Tj rating | Suitable for non-critical 12 V accessory rails where thermal margin is ample and cost is primary constraint |
Compared with VS-50SQ060 and SB560-E3/54, STPS560SFY delivers superior thermal performance (2.0 °C/W), automotive qualification, and manufacturability (wettable flanks), making it the only option qualified for engine-bay DC/DC and reverse-protection in safety-critical systems.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPS560SFY supports continuous operation up to 160 °C case temperature (Tc) at its full 5 A average forward current rating, as specified in Table 1 of DS12934. Exceeding this requires derating per Figure 1, which shows linear reduction to zero current at 175 °C Tc.
Does STPS560SFY require a heatsink for 5 A operation?
No external heatsink is required if the PCB provides ≥6 cm² of 35 µm-thick copper directly under the cathode tab, achieving Rth(j-a) ≈ 25 °C/W (per Figure 7). With that layout, junction temperature stays below 175 °C at 5 A and 25 °C ambient-provided airflow and board layer stack support conduction.
How does the dual-anode configuration improve performance?
The dual-anode structure halves the effective series resistance compared to single-anode equivalents, reducing VF by ~0.05–0.08 V across the 2.5–5 A range and distributing current density to enhance reliability under surge conditions like IFSM = 230 A.
Is STPS560SFY compatible with lead-free reflow profiles?
Yes-STPS560SFY is qualified for standard JEDEC J-STD-020D lead-free reflow, with peak temperature tolerance up to 260 °C for 30 seconds. Its PSMC package uses UL94 V0 epoxy and meets IPC/JEDEC moisture sensitivity level MSL-1, eliminating bake requirements prior to assembly.
