STMicroelectronics STPS1L60MF

Overview

STPS1L60MF from STMicroelectronics is a 60 V, 1 A low-drop surface-mount Schottky rectifier in STmite flat package, featuring typical forward voltage of 0.50 V at 125 °C and 1 A, avalanche rating up to 85 W (10 µs), and junction temperature rating of 175 °C. It is designed for high-frequency DC–DC converters and compact battery chargers where low conduction loss and thermal efficiency are critical.

For engineers reviewing the STPS1L60MF datasheet, STPS1L60MF pinout, STPS1L60MF application, or STPS1L60MF equivalent, this page delivers verified electrical parameters, thermal resistance data (R_th(j-c) = 20 °C/W), package mechanical dimensions, real-world use cases in auxiliary power and set-top box designs, and validated alternative parts with documented functional trade-offs.

Technical Context

This Schottky rectifier uses a planar silicon structure optimized for minimal reverse recovery charge and negligible switching losses-critical in >100 kHz SMPS topologies. Its low VF and high T_j(max) enable operation without heatsinking in space-constrained auxiliary rails.

The STmite flat package provides direct thermal path from junction to PCB copper via exposed cathode tab, achieving R_th(j-c) = 20 °C/W. Avalanche energy rating (85 W at 10 µs) supports robustness against inductive transients in unregulated flyback or buck-derived supplies.

FAQ

What is the maximum allowable PCB copper area for STPS1L60MF's cathode tab?

The STmite flat package requires a minimum 2.0 cm² copper area under the cathode tab for full 1 A continuous current at T_L = 160 °C. Datasheet Figure 27 specifies a recommended footprint of 4.13 mm × 1.95 mm (0.077″ × 0.163″), which equals ~0.81 cm²; doubling this area to ≥2.0 cm² ensures R_th(j-a) ≤ 40 °C/W and prevents thermal runaway.

Does STPS1L60MF support reflow soldering per JEDEC J-STD-020?

Yes-STPS1L60MF is rated MSL1 (Moisture Sensitivity Level 1) per JEDEC J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH and subjected to standard Pb-free reflow profiles (peak 260 °C, 30 sec max) without baking or special handling. Its ECOPACK2 halogen-free epoxy passes all required thermal cycling and solderability tests.

How does STPS1L60MF's avalanche rating compare to standard Schottky diodes?

Unlike most Schottky diodes-which fail catastrophically under reverse overvoltage-STPS1L60MF is tested to withstand 85 W of single-pulse avalanche energy at 10 µs (T_j = 125 °C). This corresponds to ~120 V transient clamping capability in practical circuits, making it suitable for unclamped flyback or boost converters where cost prohibits TVS protection.

Can STPS1L60MF replace DO-41 through-hole diodes in existing designs?

No-STPS1L60MF uses STmite flat surface-mount packaging and cannot be substituted for DO-41 parts (e.g., STPS1L60RL) without PCB redesign. Its 3.8 mm × 2.95 mm footprint and cathode-tab-down orientation require dedicated land pattern per Figure 27; thermal and electrical performance also differ significantly due to lower R_th(j-c) and higher I_F(AV) at same ambient.
