Product details
Overview
STPS360AFY from STMicroelectronics is an automotive-grade Schottky barrier rectifier in SOD128Flat package, rated for 60 V repetitive peak reverse voltage (VRRM), 3 A average forward current (IF(AV)), and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.49 V typ. at 3 A, 125 °C) with negligible switching losses, enabling high-efficiency DC-DC conversion in engine control units and ADAS power supplies.
For engineers reviewing the STPS360AFY datasheet, STPS360AFY pinout, STPS360AFY application, or STPS360AFY equivalent, key selection criteria include its AEC-Q101 qualification, avalanche-rated 140 W peak power capability, thermal resistance of 16 °C/W (junction-to-lead), and ECOPACK®-compliant lead-free SOD128Flat packaging for under-hood automotive environments.
Technical Context
This Schottky rectifier uses a planar silicon structure optimized for high-frequency operation in miniature switched-mode power supplies. Its low VF–IR trade-off enables stable conduction loss performance across -40 to +175 °C ambient range, supported by guaranteed VRRM over full junction temperature range and 65 A non-repetitive surge rating.
The device features avalanche energy capability (PARM = 140 W at 10 µs pulse, Tj = 125 °C) and is characterized for thermal stability under pulsed load conditions, with normalized Zth(j-l) derating curves provided for transient thermal design. Rth(j-l) = 16 °C/W ensures predictable heat transfer to PCB copper pads without external heatsink.
Key Specifications

| IF(AV) | 3 A - Average forward current at TL = 140 °C with 50% duty cycle square pulse |
| VF(typ.) | 0.49 V - Forward voltage drop at IF = 3 A, Tj = 125 °C, defining conduction loss baseline |
| IR(max) | 30 mA - Max reverse leakage at VR = 60 V, Tj = 125 °C, critical for standby power budget |
| Rth(j-l) | 16 °C/W - Junction-to-lead thermal resistance, enabling direct PCB copper pad thermal path design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS36030P5T3G | Same 60 V VRRM, 3 A IF(AV), but TO-277A package (Rth(j-a) ≈ 50 °C/W vs. 16 °C/W) | Larger footprint, higher thermal resistance limits use in high-power density designs | Prefer when legacy TO-277A footprint compatibility is required over thermal performance |
| Vishay VS-3EYH06-M3/54 | 60 V VRRM, 3 A IF(AV), SOD128 package variant but no AEC-Q101 qualification or avalanche rating | Not qualified for automotive; lacks PPAP support and guaranteed high-temp VRRM | Select only for industrial or consumer applications where automotive reliability is not mandated |
Compared with NSS36030P5T3G and VS-3EYH06-M3/54, STPS360AFY uniquely combines AEC-Q101 qualification, 175 °C junction rating, and 140 W avalanche capability in the thermally efficient SOD128Flat package-making it the only option qualified for safety-critical, high-temperature automotive power conversion.

FAQ
Is STPS360AFY suitable for use in non-automotive applications?
Yes, STPS360AFY can be used in industrial or commercial power supplies where its 175 °C junction rating, low VF, and avalanche capability provide design margin. However, its AEC-Q101 qualification and PPAP documentation are specifically intended for automotive use, and cost structure reflects that target market.
What is the recommended PCB layout for optimal thermal performance?
Maximize copper area under both anode and cathode pads using ≥35 µm thick copper layers. Connect cathode pad directly to internal ground or power planes via ≥6 thermal vias (0.3 mm diameter, 0.8 mm pitch). Avoid narrow traces; maintain ≥1.5 mm pad extension beyond package outline per side.
Does STPS360AFY require a heatsink in typical automotive applications?
No external heatsink is required. With Rth(j-l) = 16 °C/W and proper PCB copper area (≥4 cm² per pad), junction temperature remains within 175 °C limit at 3 A continuous load and 105 °C ambient. Thermal simulation using ST's Zth(j-l) curves is recommended for worst-case transient conditions.
How does the 140 W avalanche rating translate to real-world protection?
The 140 W rating applies to 10 µs pulses at Tj = 125 °C and corresponds to ~1.4 J of single-pulse energy. In practice, this enables reliable clamping of inductive kickback from solenoid drivers or motor gate drivers without degradation-verified per AEC-Q101 avalanche test standard.
