Product details
Overview
STPS3L60S from STMicroelectronics is a 60 V, 3 A average forward current Schottky rectifier in SMC package, featuring 0.56 V typical forward voltage at 125 °C and 3 A, 20 °C/W junction-to-lead thermal resistance, and avalanche capability up to 115 W (10 µs pulse). It is engineered for high-frequency DC/DC converters in telecom power supplies and battery chargers.
For engineers reviewing the STPS3L60S datasheet, STPS3L60S pinout, STPS3L60S application, or STPS3L60S equivalent, key selection criteria include low conduction loss (0.54×IF(AV) + 0.037×IF²(RMS)), negligible switching losses, ECOPACK®2 compliance, and thermal performance under δ = 0.5 square-wave duty cycle.
Technical Context
This Schottky rectifier operates with zero minority-carrier storage, eliminating reverse recovery charge and enabling operation at frequencies beyond 1 MHz. Its low VF (0.56 V typ. @ 125 °C, 3 A) and low Rth(j-l) (20 °C/W) directly reduce conduction loss and improve thermal margin in compact SMPS layouts.
The device supports repetitive avalanche energy handling (115 W, 10 µs, Tj = 125 °C) and exhibits stable reverse leakage (<15 mA @ 125 °C, VR = 60 V), making it suitable for unregulated input stages and transient-prone telecom DC/DC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V telecom bus and 24 V industrial DC/DC inputs. |
| IF(AV) | 3 A - Average forward current at Tl = 100 °C, δ = 0.5; sets continuous output capability in 12–24 V battery charger secondary side. |
| VF (typ.) | 0.56 V @ 125 °C, 3 A - Low conduction drop reduces power loss to ~1.7 W at full load, critical for thermally constrained SMC footprint. |
| Rth(j-l) | 20 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pad heat sinking without external heatsink in ≤3 A applications. |
| IFSM | 75 A @ 10 ms sinusoidal - Surge rating supports inrush current handling during cold-start of DC/DC converters. |
| IR (max) | 15 mA @ 125 °C, VR = VRRM - Controlled leakage ensures minimal standby loss in always-on telecom power modules. |
Pinout & Package
STPS3L60S is housed in an SMC (DO-214AB) surface-mount package with two terminals: cathode and anode. The package features gull-wing leads, epoxy body compliant with UL94 V0, and a recommended footprint of 8.19 mm × 5.11 mm (3.14 mm pad spacing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to unregulated DC input (e.g., rectified AC or upstream converter output); must withstand 60 V reverse bias. |
| Cathode | Output current exit point | Drives downstream LC filter or battery; low VF minimizes voltage drop and improves regulation accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero reverse recovery time (Qrr ≈ 0) eliminates turn-off loss and EMI in >500 kHz DC/DC topologies. |
| Low thermal resistance | Rth(j-l) = 20 °C/W allows ≥2.5 W dissipation with <50 °C temperature rise on 3 cm² copper, simplifying thermal design. |
| Avalanche capability | 115 W peak avalanche power (10 µs) protects against inductive kickback in flyback and boost converters. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free reflow requirements per JEDEC J-STD-020, supporting global environmental mandates. |
Applications
| Set-top Box Power Supply | Battery Charger Secondary Side |

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 NSS3L60MX | Same 60 V VRRM, 3 A IF(AV), but VF = 0.65 V (typ. @ 125 °C, 3 A); Rth(j-l) = 25 °C/W. | Higher conduction loss (+0.27 W at 3 A) and reduced thermal margin limit use in sealed enclosures above 60 °C ambient. | Select when legacy ON Semi supply chain alignment is required and thermal headroom exceeds 15 °C. |
| Vishay SS36HE3/57T | Identical 60 V/3 A rating, VF = 0.70 V (typ. @ 25 °C, 3 A), no specified avalanche rating; Rth(j-l) = 22 °C/W. | Lacks avalanche capability and has higher VF at elevated temperature, limiting suitability in telecom surge environments. | Prefer only in non-surge-critical consumer lighting applications with ample thermal margin. |
Compared with NSS3L60MX and SS36HE3/57T, STPS3L60S delivers lower VF at high temperature and verified 115 W avalanche robustness-critical for telecom and industrial DC/DC where input transients and thermal cycling dominate failure modes.

FAQ
What is the maximum junction temperature and how is it enforced?
The STPS3L60S has a maximum operating junction temperature of 150 °C, validated under conditions where dPtot/dTj < 1/Rth(j-a) to prevent thermal runaway. This limit is maintained by ensuring the thermal design meets Rth(j-l) = 20 °C/W and provides adequate copper area per the SMC footprint recommendation (≥3 cm² per lead).
Does STPS3L60S require a heatsink in standard PCB mounting?
No external heatsink is required when mounted on a standard FR4 PCB with ≥3 cm² of 35 µm copper per lead, as confirmed by Figure 9 in DS1596. At 3 A average current and 25 °C ambient, junction temperature remains below 110 °C with this copper area, well within the 150 °C limit.
How does the avalanche capability impact system-level reliability?
The 115 W repetitive avalanche rating (10 µs, Tj = 125 °C) allows STPS3L60S to safely absorb inductive energy spikes during MOSFET switching transitions in flyback and forward converters, reducing risk of catastrophic failure during line surges or short-circuit events without requiring snubber networks.
Is STPS3L60S compatible with lead-free reflow profiles?
Yes-STPS3L60S is ECOPACK®2 certified and qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. The SMC package's UL94 V0 epoxy ensures mechanical stability and delamination resistance under these conditions.
