Product details

Overview

STPS1L60A from STMicroelectronics is a 60 V, 1 A surface-mount Schottky power rectifier in SMA package, featuring low forward voltage drop (0.50 V typ. at 125 °C, 1 A), avalanche rating, and ECOPACK2 compliance. It serves as a high-efficiency output rectifier in low-voltage, high-frequency DC-DC converters for desktop PSUs and battery chargers.

For engineers reviewing the STPS1L60A datasheet, STPS1L60A pinout, STPS1L60A application, or STPS1L60A equivalent, key selection criteria include forward voltage drop at elevated junction temperature, avalanche energy capability, thermal resistance junction-to-lead (30 °C/W), and SMA package compatibility with automated SMT assembly.

Technical Context

This Schottky rectifier uses a planar silicon structure optimized for minimal conduction loss and negligible switching loss-critical in high-frequency SMPS where reverse recovery is absent. Its 175 °C maximum junction temperature enables operation in thermally constrained spaces without forced cooling.

The device exhibits low reverse leakage (≤5 mA at 125 °C, VR = VRRM) and stable VF across temperature (0.50–0.54 V at 125 °C, 1 A), supporting predictable thermal design. Avalanche rating (85 W, 10 µs pulse) provides robustness against inductive transients in flyback and LLC topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in secondary-side rectification of ≤48 V output supplies.
I_F(AV)	1 A - Average forward current at TL = 155 °C; supports continuous conduction in compact 12–24 V auxiliary rails.
V_F(typ.)	0.50 V @ 125 °C, 1 A - Low conduction loss reduces power dissipation to ~0.5 W, easing thermal management on 1–2 cm² copper pads.
R_th(j-l)	30 °C/W - Junction-to-lead thermal resistance in SMA package; enables direct PCB copper heat spreading without heatsink.
I_FSM	40 A @ 10 ms - Non-repetitive surge current rating; withstands startup inrush and transient overloads in battery charger inputs.
T_j(max)	175 °C - Maximum junction temperature; allows full-rated operation in sealed enclosures up to 105 °C ambient with proper layout.
ECOPACK2	Compliant - Halogen-free, RoHS-compliant packaging meeting stringent environmental requirements for consumer and industrial end equipment.

Pinout & Package

Applications

Desktop Power Supply

Battery Charger

Use Scenario: Secondary-side synchronous rectification replacement in 12 V/5 V auxiliary rails of ATX PSUs.

IC Role / Device Role / Timing Role: Output rectifier converting high-frequency transformer AC to regulated DC; operates continuously at 100–500 kHz.

Use Value: 0.50 V V_F reduces conduction loss by ~35% vs. standard PN diodes, lowering thermal stress on PCB and improving no-load efficiency.

Use Scenario: Output rectification in compact wall-adapters for smartphones and tablets (5–9 V, ≤2 A).

IC Role / Device Role / Timing Role: Unidirectional current path after transformer; handles pulsed DC with δ = 0.5 duty cycle.

IC Role / Device Role / Timing Role: High-frequency rectifier in quasi-resonant flyback converter operating at 65–130 kHz.

Use Value: Low IR leakage (<5 mA @ 125 °C) minimizes standby power loss, helping meet Energy Star Tier 2 requirements.

Use Scenario: Secondary-side rectification in isolated LED drivers for commercial downlights (24–48 V output).

IC Role / Device Role / Timing Role: Freewheeling path for constant-current regulator; conducts during transformer reset phase.

Use Value: Avalanche rating absorbs inductive kickback from transformer leakage inductance, eliminating need for external TVS.

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 SB160-E3/54	V_F = 0.72 V @ 25 °C, 1 A; higher conduction loss; TO-277 package (R_th(j-l) ≈ 25 °C/W).	Larger footprint; less suitable for ultra-thin adapters due to height and thermal profile.	Select when legacy TO-277 board space exists and cost sensitivity outweighs efficiency gain.
Vishay VS-1EWH06-M3/5AT	V_F = 0.54 V @ 125 °C, 1 A; same SMA package; lower I_FSM (30 A vs. 40 A).	Reduced surge margin in high-inrush battery charging circuits; identical thermal performance.	Prefer for cost-optimized designs where surge events are clamped externally or infrequent.

Compared with SB160-E3/54 and VS-1EWH06-M3/5AT, STPS1L60A delivers the lowest verified V_F at operating temperature and highest avalanche energy-making it optimal for thermally dense, high-reliability 1 A auxiliary rails where efficiency and transient robustness are jointly critical.

FAQ

What is the maximum allowable ambient temperature for STPS1L60A at full 1 A load?

At δ = 0.5 square-wave conduction and using the SMA package on a standard FR4 PCB with 2 cm² copper per lead, STPS1L60A supports up to 105 °C ambient while maintaining T_j ≤ 175 °C-verified by Figure 2 in DS2133. Derating begins above this point per the IF(AV) vs. Tamb curve.

Does STPS1L60A require a heatsink in typical SMT applications?

No heatsink is required. With R_th(j-l) = 30 °C/W and typical PCB copper spread, the device dissipates ≤0.5 W at 1 A/125 °C, resulting in <15 °C rise above ambient-well within limits for most enclosed power supplies. Thermal relief via copper pour is sufficient.

How does the avalanche rating of STPS1L60A improve system reliability?

The 85 W, 10 µs avalanche capability allows STPS1L60A to absorb transient overvoltage spikes-such as those caused by transformer leakage inductance during MOSFET turn-off-without failure. This eliminates the need for external clamping components in many flyback designs, reducing BOM count and board area.

Is STPS1L60A compatible with lead-free reflow soldering processes?

Yes. STPS1L60A is qualified for standard Pb-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C. Its ECOPACK2-compliant materials and MSL1 rating mean no pre-bake is needed, supporting high-yield automated assembly.
