Product details
Overview
STPS3L60SY from STMicroelectronics is an AEC-Q101-qualified automotive Schottky rectifier in SMC (DO-214AB) package, rated for 3 A average forward current, 60 V repetitive peak reverse voltage, and 150 °C maximum junction temperature; it delivers low forward voltage drop (0.65 V max at 3 A, 125 °C) with negligible switching losses, and is designed for DC/DC chargers in automotive power systems.
For engineers reviewing the STPS3L60SY datasheet, STPS3L60SY pinout, STPS3L60SY application, or STPS3L60SY equivalent, key selection criteria include avalanche capability (1600 W, 1 µs), thermal resistance (20 °C/W junction-to-leads), reverse leakage (15 mA max at 125 °C), and ECOPACK®2 compliance for automotive-grade reliability and environmental safety.
Technical Context
This Schottky rectifier operates as a unidirectional power conversion device in high-frequency DC/DC converters, leveraging metal–semiconductor junction physics to eliminate minority-carrier storage delay. Its low VF (0.56–0.65 V typ./max at 3 A, 125 °C) and high dV/dt rating (10,000 V/µs) enable efficient operation in fast-switching topologies without snubbers.
Avalanche energy handling (1600 W, 1 µs pulse) and specified avalanche capability support robustness against transient overvoltage events in automotive 12 V/48 V battery systems. Thermal design is enabled by Rth(j-l) = 20 °C/W and validated junction temperature range of –40 to +150 °C under continuous conduction mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; ensures compatibility with 48 V automotive bus transients. |
| IF(AV) | 3 A at TC = 100 °C, δ = 0.5 - Continuous forward current rating defining thermal limits in PCB-mounted operation. |
| VF (max) | 0.65 V at IF = 3 A, Tj = 125 °C - Low conduction loss enabling >92% efficiency in 12 V → 5 V buck converters. |
| IRRM | 1 A at VR = VRRM, tp = 2 µs, f = 1 kHz - Confirmed reverse recovery immunity for high-frequency PWM operation. |
| Rth(j-l) | 20 °C/W - Junction-to-leads thermal resistance enabling direct heatsink coupling via PCB copper pour or clip bonding. |
| PARM | 1600 W at tp = 1 µs, Tj = 25 °C - Avalanche energy rating supporting load-dump surge tolerance per ISO 7637-2. |
| dV/dt | 10,000 V/µs - Critical rate-of-rise immunity preventing spurious turn-on during fast edge transients in motor drive inverters. |
Pinout & Package
STPS3L60SY is housed in SMC (JEDEC DO-214AB) surface-mount package with two terminals: cathode and anode. The package features gull-wing leads, epoxy body compliant with UL94 V0, and lead-free construction per ECOPACK®2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input rail (e.g., battery or switch node); must be routed with low-inductance trace for high di/dt stability. |
| Cathode | Forward current exit point | Connected to output filter inductor or capacitor; serves as reference for synchronous rectifier control signals. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | No reverse recovery charge (Qrr ≈ 0), eliminating turn-off loss and EMI in >200 kHz DC/DC converters. |
| AEC-Q101 qualification | Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock per JESD47. |
| Low thermal resistance | Rth(j-l) = 20 °C/W enables 3 A operation with <30 °C junction rise above PCB leads at 100 °C ambient. |
| Avalanche capability | Rated 1600 W single-pulse avalanche power supports ISO 16750-2 load dump protection without external TVS. |
| ECOPACK®2 compliance | Lead-free, halogen-free, RoHS-compliant packaging meeting automotive OEM chemical content requirements. |
Applications

IC Role / Device Role / Timing Role: Low-leakage (15 mA max at 125 °C) isolation diode preserving stored charge during extended sleep modes. Use Value: 15 mA IR at 125 °C extends hold-up time by >2.3× versus legacy Schottky diodes with 50 mA leakage. |
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-3EY60-M3/57T | Same SMC package, 3 A/60 V rating, but VF = 0.72 V max (125 °C) and no AEC-Q101 certification. | Not qualified for automotive underhood use; limited to industrial or consumer DC/DC. | Select only if AEC-Q101 is not required and higher VF is acceptable for thermal budget. |
| ON Semiconductor SB360-E3/57T | SMC package, 3 A/60 V, VF = 0.75 V max (125 °C), no avalanche rating or automotive qualification. | Lacks PARM specification and dV/dt rating; unsuitable for load-dump or fast-edge environments. | Use only in cost-sensitive non-automotive applications where surge immunity is externally managed. |
Compared with VS-3EY60-M3/57T and SB360-E3/57T, STPS3L60SY uniquely combines AEC-Q101 qualification, 1600 W avalanche rating, and 0.65 V VF - making it the only option qualified for direct integration into automotive 48 V DC/DC charger primary-side freewheeling paths without derating or external protection.

FAQ
Is STPS3L60SY suitable for synchronous rectification?
No - STPS3L60SY is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It functions as a freewheeling or output rectifier in non-synchronous topologies. For synchronous designs, ST offers dedicated gate drivers (e.g., STDRIVE601) paired with discrete N-channel MOSFETs.
What is the maximum PCB copper area needed for thermal performance at 3 A?
With Rth(j-a) ≈ 75 °C/W on FR4 (35 µm Cu), a minimum 10 cm² copper pour per lead is recommended to maintain Tj ≤ 150 °C at 100 °C ambient. Using 2 oz (70 µm) Cu or internal plane connections can reduce required area to ~4 cm².
Does STPS3L60SY require a heatsink?
No external heatsink is required when mounted on ≥10 cm² of 2-layer FR4 PCB with 35 µm copper and thermal vias to inner ground planes. Its Rth(j-l) = 20 °C/W allows sufficient heat transfer through leads alone under typical automotive ambient conditions.
Can STPS3L60SY replace a standard PN rectifier in existing 12 V designs?
Yes - it is a direct replacement for 3 A/60 V PN rectifiers (e.g., 1N5408) in DC/DC converters, offering lower VF (0.65 V vs. 0.95 V), no reverse recovery, and higher efficiency. However, layout must accommodate SMC footprint and verify avalanche margin if replacing in surge-prone locations.
