Product details
Overview
STPS5L60SFY from STMicroelectronics is an AEC-Q101-qualified automotive power Schottky rectifier in PSMC (TO-277A) package, rated for 5 A average forward current, 60 V repetitive peak reverse voltage, and 150 °C maximum junction temperature. It delivers a typical forward voltage drop of 0.40 V at 2.5 A and 25 °C, enabling low conduction loss in high-efficiency DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the STPS5L60SFY datasheet, STPS5L60SFY pinout, STPS5L60SFY application, or STPS5L60SFY equivalent, key selection criteria include its wettable flanks for automated optical inspection, avalanche capability (280 W at 10 µs), and guaranteed VRRM across -40 °C to +150 °C - critical for under-hood automotive power systems requiring robust thermal and surge resilience.
Technical Context
This Schottky rectifier uses a planar metal-silicon junction optimized for low VF and negligible switching losses, eliminating minority-carrier storage delay. Its 1.9 °C/W junction-to-case thermal resistance supports high-power-density mounting on heatsinked PCB copper pads.
The device features specified avalanche energy handling (PARM = 280 W, tp = 10 µs, Tj = 125 °C) and reverse leakage current ≤150 mA at 125 °C and VR = VRRM - enabling reliable freewheeling and clamping in inductive switching environments such as automotive body control modules and EPS motor drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 5 A - supports continuous output current in compact 12 V–48 V automotive DC/DC stages without forced air cooling |
| VRRM | 60 V - withstands load-dump transients up to ISO 7637-2 Pulse 5a in 48 V systems |
| VF (typ.) | 0.40 V @ 2.5 A, 25 °C - reduces conduction loss to ~1.0 W vs. >2.5 W for comparable Si diodes |
| Tj (max.) | 150 °C - enables operation adjacent to engine bay electronics with no derating below ambient 105 °C |
| Rth(j-c) | 1.9 °C/W - allows direct thermal coupling to copper pour or heatsink for stable thermal management |
| IR (max.) | 150 mA @ 125 °C, VR = VRRM - ensures minimal standby power loss in always-on vehicle networks |
| IFSM | 220 A @ 10 ms - sustains short-circuit fault currents in battery protection circuits |
Pinout & Package
Package: PSMC (TO-277A) - surface-mount, 3-terminal power package with exposed cathode tab for thermal and electrical connection; wettable flanks enable AOI-compatible solder joint verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Anode 2 | Parallel input terminals | Dual-anode configuration lowers effective series resistance and improves current sharing uniformity |

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 NSS5L60P5T3G | Same 5 A / 60 V rating; VF = 0.49 V @ 5 A, 25 °C; Rth(j-c) = 2.5 °C/W | Higher VF increases conduction loss by ~0.45 W at full load; less suitable for thermally constrained modules | Prefer when legacy footprint compatibility with SOD-123FL is required over thermal performance |
| Vishay VS-5EY60S-M3/5BT | 5 A / 60 V; VF = 0.52 V @ 5 A, 25 °C; no AEC-Q101 qualification; Rth(j-c) = 2.2 °C/W | Lacks automotive qualification and avalanche rating - unsuitable for safety-critical or high-surge environments | Select only for non-automotive industrial DC/DC where cost is prioritized over qualification and ruggedness |
Compared with NSS5L60P5T3G and VS-5EY60S-M3/5BT, STPS5L60SFY offers the lowest VF (0.40 V), best thermal resistance (1.9 °C/W), and full AEC-Q101 + avalanche certification - making it the sole choice for thermally dense, safety-aware automotive power stages.

FAQ
Is STPS5L60SFY suitable for 48 V automotive systems?
Yes. With 60 V VRRM and AEC-Q101 qualification, STPS5L60SFY is explicitly rated for 48 V nominal systems including load-dump transient immunity per ISO 7637-2. Its 150 °C Tj(max) and low VF ensure stable operation in under-hood environments where ambient temperatures exceed 105 °C.
What is the recommended PCB layout for thermal performance?
Maximize copper area under the exposed cathode tab using ≥6 cm² of 2 oz (70 µm) copper connected via ≥8 thermal vias (0.3 mm diameter, 0.8 mm pitch) to inner-layer ground planes. The datasheet specifies Rth(j-a) drops from 120 °C/W to <35 °C/W with this layout - critical for sustaining 5 A continuous current.
Does STPS5L60SFY have a documented avalanche energy rating?
Yes. The datasheet specifies PARM = 280 W for tp = 10 µs pulses at Tj = 125 °C. This corresponds to an avalanche energy of 2.8 mJ, validated per AEC-Q101 stress test conditions - enabling use in freewheeling paths subject to inductive switching transients without external snubbers.
Can STPS5L60SFY replace silicon PN diodes in existing designs?
Yes, with design review. Its lower VF reduces conduction loss, but its higher IR at elevated temperature requires checking reverse-bias power dissipation in high-temperature hold conditions. Also verify that the PSMC (TO-277A) footprint and dual-anode layout match mechanical constraints before drop-in replacement.
