Product details
Overview
STPS2L60RL from STMicroelectronics is a 60 V, 2 A low-drop power Schottky rectifier in SMA package, optimized for high-frequency switch-mode power supplies and battery chargers. It delivers typ. 0.51 V forward voltage at 2 A and 125 °C, supports 150 °C max junction temperature, and features avalanche rating for robust transient handling in auxiliary and low-voltage DC-DC stages.
For engineers reviewing the STPS2L60RL datasheet, STPS2L60RL pinout, STPS2L60RL application, or STPS2L60RL equivalent, this device is selected for conduction-loss-sensitive designs requiring fast recovery, negligible switching losses, and surface-mount compatibility in compact AC/DC adapters, set-top box PSUs, and portable charger circuits.
Technical Context
This Schottky rectifier operates without minority-carrier storage delay, enabling zero reverse recovery time and eliminating associated switching losses. Its metal–semiconductor junction yields low VF and high IF(AV) capability within thermally constrained layouts.
Designed for δ = 0.5 square-wave operation, it sustains 2 A average forward current at TL = 115 °C (SMA), with Rth(j-l) = 25 °C/W and thermal runaway avoidance ensured under (dPtot/dTj) < (1/Rth(j-a)) conditions on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V input rails and flyback clamp circuits. |
| IF(AV) | 2 A - Average forward current rating at TL = 115 °C (SMA); sets continuous output capability in 5–12 V secondary-side rectification. |
| VF(typ.) | 0.51 V @ 2 A, 125 °C - Low conduction loss enables >94% efficiency in 5 V/2 A auxiliary supplies and extends battery runtime in portable chargers. |
| Tj(max) | +150 °C - Maximum junction temperature; allows operation in sealed enclosures or high-ambient environments like set-top boxes. |
| Rth(j-l) | 25 °C/W - Junction-to-lead thermal resistance (SMA); determines heatsink-free power handling up to ~0.8 W at 115 °C ambient. |
| IFSM | 75 A @ tp = 10 ms - Non-repetitive surge rating; withstands inrush currents during cold-start of desktop PSUs and lighting drivers. |
Pinout & Package
STPS2L60RL is housed in an SMA (DO-214AC) surface-mount package with cathode band marking. The package measures 4.80–5.35 mm × 2.25–2.90 mm × 1.90–2.45 mm (L × W × H) and uses lead-free, UL94 V0 epoxy.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to transformer secondary or switching node; carries full load current with minimal IR drop due to low-resistance metallization. |
| Cathode | Output current terminal | Marked by band; ties to output capacitor and ground return path; designed for low-inductance layout to suppress ringing in high-dI/dt applications. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero reverse recovery time eliminates turn-off loss and EMI generation in >100 kHz SMPS topologies. |
| Low VF at high Tj | 0.51 V typ. @ 125 °C ensures stable conduction loss across automotive and industrial ambient ranges. |
| Avalanche rated | 115 W peak avalanche power (tp = 10 µs) protects against inductive kickback in unclamped flyback or boost converters. |
| ECOPACK2 compliance | Meets RoHS, halogen-free, and REACH requirements for consumer electronics and EU-market lighting products. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS26-E3/57T (Vishay) | Same VRRM (60 V), IF(AV) = 2 A, VF = 0.75 V @ 2 A, 25 °C; higher VF increases conduction loss by ~47% at room temp. | Lacks avalanche rating; unsuitable for unclamped inductive switching nodes. | Select when cost sensitivity outweighs efficiency and ruggedness requirements in non-critical auxiliary rails. |
| MBR260 (ON Semiconductor) | VRRM = 60 V, IF(AV) = 2 A, VF = 0.72 V @ 2 A, 25 °C; TO-220AB package requires heatsink for >1 A continuous. | Through-hole mounting limits density; thermal performance inferior to SMA on FR4 without copper pour. | Prefer only where legacy through-hole assembly or higher surge tolerance (IFSM = 100 A) is mandatory. |
Compared with SS26-E3/57T and MBR260, STPS2L60RL offers superior thermal efficiency in SMT layouts, guaranteed avalanche ruggedness for flyback clampless designs, and ECOPACK2 compliance-making it optimal for space-constrained, high-reliability consumer power stages.

FAQ
What is the maximum allowable ambient temperature for STPS2L60RL in SMA package?
At TL = 115 °C (lead temperature), STPS2L60RL sustains 2 A average forward current. With Rth(j-l) = 25 °C/W and typical PCB copper area, ambient temperature must remain ≤80 °C to maintain Tj ≤150 °C. Derating curves in Figure 2 confirm 1.6 A at 100 °C ambient on standard FR4.
Does STPS2L60RL require a heatsink in typical 2 A applications?
No heatsink is required for 2 A continuous operation if mounted on ≥2.5 cm² copper per lead (Rth(j-a) ≈ 40 °C/W). Thermal data shows Pdiss ≈ 1.02 W at 2 A/125 °C; with 25 °C/W Rth(j-l), junction rise is ~25.5 °C above lead temp-well within limits on standard 2-layer boards.
How does the avalanche rating improve reliability in flyback converters?
The 115 W peak avalanche power (tp = 10 µs, Tj = 125 °C) allows STPS2L60RL to absorb energy from transformer leakage inductance without failure. This eliminates need for external RCD snubbers in cost-sensitive flyback designs, reducing component count and improving long-term reliability under overvoltage stress.
Is STPS2L60RL compatible with lead-free reflow profiles?
Yes. STPS2L60RL is qualified for lead-free soldering per JEDEC J-STD-020, supporting peak reflow temperatures up to 260 °C. Its UL94 V0 epoxy and Pb-free terminations meet IPC-A-610 Class 2 requirements for consumer-grade power assemblies.
