Product details
Overview
STPS1L60 from STMicroelectronics is a 60 V, 1 A low-drop surface-mount Schottky rectifier optimized for high-frequency DC-DC converters and auxiliary power supplies. It features a typical forward voltage of 0.50 V at 125 °C and 1 A, negligible switching losses, avalanche rating up to 85 W (10 µs), and operates up to 175 °C junction temperature - enabling compact, thermally efficient designs in battery chargers and set-top box power stages.
For engineers reviewing the STPS1L60 datasheet, STPS1L60 pinout, STPS1L60 application, or STPS1L60 equivalent, key selection criteria include its 60 V reverse voltage rating, 1 A average forward current capability across multiple packages (SMA, SOD123Flat, STmite flat), low VF stability over temperature, and ECOPACK2-compliant packaging for industrial and consumer power systems.
Technical Context
The STPS1L60 is a unidirectional, single-die Schottky barrier diode with metal–semiconductor junction architecture, delivering fast recovery (no minority carrier storage) and zero reverse recovery charge. Its thermal design relies on package-specific junction-to-lead or junction-to-case resistance - e.g., 20 °C/W for SMA Flat Notch and SOD123Flat, 30 °C/W for standard SMA - enabling predictable conduction loss estimation using P = 0.42 × IF(AV) + 0.12 × IF²(RMS).
It supports pulsed surge currents up to 60 A (SMA Flat Notch, 10 ms sine) and exhibits low reverse leakage (<5 mA at 125 °C, VR = 60 V). The device's avalanche robustness (85 W, 10 µs, Tj = 125 °C) allows operation under transient overvoltage conditions without external clamping in low-power SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V and 54 V auxiliary rails. |
| IF(AV) | 1 A - Average forward current at specified thermal conditions (e.g., TL = 155 °C for SMA); sets continuous output capability in low-power DC-DC stages. |
| VF(typ.) | 0.50 V @ 1 A, 125 °C - Low conduction loss enables >92% efficiency in 5 V/1 A buck-derived auxiliary supplies. |
| Tj(max.) | 175 °C - High junction temperature rating permits operation in thermally constrained enclosures without forced cooling. |
| IFSM | 60 A @ 10 ms (SMA Flat Notch) - Supports inrush current handling during cold-start in battery charger input stages. |
| Rth(j-l) | 20 °C/W (SMA Flat Notch, SOD123Flat) - Enables direct PCB copper pad thermal coupling for passive heatsinking in space-constrained layouts. |
| ECOPACK2 | Compliant - Meets RoHS, halogen-free, and lead-free reflow requirements for global consumer electronics manufacturing. |
Pinout & Package
STPS1L60 is available in five discrete surface-mount and axial packages: SMA, SMA Flat Notch, SOD123Flat, STmite flat, and DO-41. All variants are two-terminal devices with anode and cathode terminals only. Cathode identification is marked by a band (SMA, SMA Flat Notch, DO-41), notch (SMA Flat Notch), or tab polarity (STmite flat).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in synchronous buck, transformer secondary center-tap). |
| Cathode | Forward current exit / output node | Connected to output rail or filter capacitor; polarity marking ensures correct orientation in high-density layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero reverse recovery charge (Qrr ≈ 0) eliminates turn-off loss and EMI in >100 kHz DC-DC converters. |
| Low forward voltage drop | VF = 0.50 V @ 1 A, 125 °C reduces conduction loss by ~35% vs. comparable 1 A silicon rectifiers. |
| Avalanche rated | 85 W repetitive peak avalanche power (10 µs, Tj = 125 °C) provides built-in transient overvoltage ruggedness. |
| Surface mount miniature packages | SOD123Flat (1.4 × 2.6 mm) and STmite flat (1.9 × 3.9 mm) enable ultra-compact 5 V/1 A auxiliary supply footprints. |
| ECOPACK2 compliant | Halogen-free, lead-free, RoHS-compliant materials meet IEC 61249-2-21 and JEDEC J-STD-020 standards. |
Applications
| Lighting Power Supply | Desktop Auxiliary Rail |
|---|---|

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 | Same 60 V VRRM, 1 A IF(AV), but VF = 0.72 V @ 1 A, 25 °C; higher Rth(j-a) (50 °C/W typical). | Higher conduction loss limits use to lower ambient or derated current in enclosed STB chassis. | Select when legacy footprint compatibility with DO-41 is required and thermal headroom exists. |
| Vishay VSKY160 | 60 V VRRM, 1 A IF(AV), VF = 0.54 V @ 1 A, 125 °C; offered only in SMA package (Rth(j-l) = 30 °C/W). | Lacks SOD123Flat and STmite flat variants, limiting miniaturization options in ultra-thin lighting modules. | Prefer for SMA-only designs where Vishay's qualification history in automotive-grade power supplies is mandated. |
Compared with SB160 and VSKY160, STPS1L60 delivers superior thermal performance in flat packages (20 °C/W Rth), lower VF at elevated temperature, and broader package flexibility - making it optimal for space- and efficiency-critical consumer power applications.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The STPS1L60 has a maximum rated junction temperature of 175 °C, verified per absolute ratings in DS2133 Rev 12. Continuous operation at this limit requires adherence to package-specific thermal resistance limits - e.g., maintaining ≤20 °C/W junction-to-ambient rise via ≥2 cm² copper pour under SOD123Flat leads per Figure 16.
Does STPS1L60 require a heatsink in a 1 A, 60 Hz full-wave rectifier application?
No - the STPS1L60 is not intended for 50/60 Hz line-frequency rectification. Its design targets high-frequency switching (≥100 kHz) where low Qrr and VF dominate performance. At 60 Hz, its low VF offers no advantage over silicon diodes, and its avalanche rating is irrelevant; use a standard 1N4007 instead.
How does the SMA Flat Notch variant differ electrically from the standard SMA package?
Electrically identical - both share identical VRRM, IF(AV), VF, and IR specifications. The SMA Flat Notch adds a physical notch and reduced profile (A1 = 0.90–1.10 mm vs. 1.90–2.45 mm) for improved mechanical stability and automated optical inspection (AOI) compatibility in high-volume SMT lines.
Can STPS1L60 be used in parallel configurations to increase current capacity?
No - Schottky diodes exhibit negative temperature coefficient VF behavior, causing current hogging if paralleled without individual ballast resistors. ST does not characterize or recommend parallel operation; for >1 A, select STPS2L60 (2 A) or STPS3L60 (3 A) in same package families.
