Product details

Overview

STPS5L60SF from STMicroelectronics is a 60 V, 5 A Schottky barrier rectifier in PSMC (TO-277A) package, optimized for high-frequency DC/DC converters and reverse battery protection. It delivers low forward voltage drop (0.40 V typ. at 2.5 A, 25 °C), 150 °C max junction temperature, and avalanche capability up to 280 W (10 µs pulse). Used in notebook adapters and set-top boxes where compact size and thermal robustness are critical.

For engineers reviewing the STPS5L60SF datasheet, STPS5L60SF pinout, STPS5L60SF application, or STPS5L60SF equivalent, key selection criteria include forward voltage at operating current, thermal resistance (R_th(j-c) = 1.9 °C/W), avalanche energy rating, wettable flanks for automated optical inspection, and ECOPACK®2 compliance for environmental requirements.

Technical Context

This Schottky rectifier uses a planar metal-silicon junction with low barrier height to minimize conduction losses and enable fast switching without minority-carrier storage. Its design targets high-frequency operation (e.g., >100 kHz DC/DC stages) where reverse recovery time is negligible and forward voltage dominates efficiency.

The PSMC (TO-277A) package integrates a thermally efficient copper tab for direct PCB conduction cooling and features wettable flanks aligned to IPC-7351B standards-enabling reliable solder-joint inspection in automated SMT lines without X-ray.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in battery reverse-polarity and flyback clamp circuits.
I_F(AV)	5 A at T_c = 135 °C - Average forward current rating under real thermal conditions; supports continuous 5 A output in compact adapter PCB layouts.
V_F (typ.)	0.44 V at 2.5 A, 25 °C - Low conduction loss enables >92% efficiency in 12 V–19 V input DC/DC stages at light-to-moderate load.
T_j (max)	150 °C - Enables operation in sealed enclosures or high ambient environments without derating below full current.
R_th(j-c)	1.9 °C/W - Junction-to-case thermal resistance allows direct heatsinking via PCB copper; supports 220 A surge without thermal runaway under short pulses.
I_FSM	220 A (10 ms sine) - Surge rating accommodates inrush currents in AC/DC front-ends and hot-plug events in portable power systems.
P_ARM	280 W (10 µs, T_j = 125 °C) - Avalanche energy capability protects against inductive switching transients in synchronous rectifier or buck-boost topologies.

Pinout & Package

STPS5L60SF is housed in the PSMC (TO-277A) surface-mount package: flat, low-profile (1.1 mm typ. height), with exposed copper thermal pad and wettable flanks. The package has three terminals: Anode (A), Cathode (K), and Thermal Pad (Tab), all electrically connected to cathode per datasheet Figure 8 and Table 4 mechanical data.

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	Input current entry point	Connected to source-side of rectification path; must be routed with low-inductance trace in high-dI/dt applications.
Cathode (K)	Output current exit point	Common node for output capacitor, control IC feedback, and thermal pad connection; carries full load current.
Thermal Pad (Tab)	Thermal and electrical reference	Electrically tied to cathode; requires ≥4 cm² copper pour on PCB for R_th(j-a) ≤ 40 °C/W per Figure 7.

Key Features

Feature	Design Value
Low profile (1.1 mm height)	Enables use in ultra-thin power adapters and space-constrained consumer electronics where Z-height < 1.2 mm is mandatory.
Wettable flanks	Facilitates 100% automated optical inspection (AOI) of solder joints without X-ray; reduces post-SMT rework in high-volume manufacturing.
Avalanche-rated (280 W, 10 µs)	Withstands transient overvoltage events in unregulated DC inputs or inductive load switching without failure-no external snubber required.
ECOPACK®2 compliance	Meets RoHS, REACH, and halogen-free requirements; certified for use in EU consumer and industrial equipment without substance-of-concern reporting.
High T_j rating (150 °C)	Permits operation in thermally dense layouts (e.g., stacked PCBs or enclosed enclosures) without forced air or additional heatsinking.

Applications

Set-Top Box Power Supply

Notebook Adapter Secondary Side

Use Scenario: Secondary-side rectification in 12 V/24 V isolated flyback converter powering SoC, tuner, and HDMI interface.

IC Role / Device Role / Timing Role: Schottky rectifier replacing conventional diodes to reduce conduction loss and improve no-load efficiency.

Use Value: 0.44 V V_F cuts diode conduction loss by ~35% vs. standard 0.68 V Schottky, extending thermal margin in sealed plastic enclosure.

Use Scenario: Output rectification in 19 V/3.35 A AC/DC adapter with 100 kHz switching frequency.

IC Role / Device Role / Timing Role: High-frequency synchronous rectifier alternative with zero reverse recovery charge.

Use Value: 1.9 °C/W R_th(j-c) enables direct thermal coupling to 6 cm² PCB copper, maintaining T_j < 135 °C at full load without heatsink.

Battery Charger Reverse Protection

DC/DC Converter Freewheeling Diode

Use Scenario: Polarity protection in 2-cell Li-ion (8.4 V) USB-C PD charger with automatic load switching.

IC Role / Device Role / Timing Role: Low-V_F series-blocking diode preventing reverse current during adapter disconnection.

Use Value: 0.35 V V_F at 125 °C ensures < 42 mW dissipation at 120 mA standby current-critical for quiescent power budget.

Use Scenario: Freewheeling path in 48 V→12 V non-isolated buck converter for automotive body control module.

IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode handling 5 A peak inductor current at 250 kHz.

Use Value: Avalanche rating absorbs 48 V × 5 A × 10 µs = 2.4 mJ energy spikes during MOSFET turn-on transitions-prevents voltage overshoot.

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 NSS5L60P5T1G	V_F = 0.52 V (5 A, 25 °C); R_th(j-c) = 2.5 °C/W; same PSMC package.	Higher conduction loss limits use in thermally constrained 5 A adapters; suitable for lower-current (<3 A) chargers.	Select if cost sensitivity outweighs 8% efficiency penalty and thermal margin is >15 °C.
Vishay SS5P6L-M3/86A	V_F = 0.49 V (5 A, 25 °C); avalanche rating not specified; TO-277A package with non-wettable flanks.	Lacks AOI-compatible flanks and transient ruggedness-requires X-ray inspection and external clamping in inductive loads.	Choose only for legacy designs where AOI capability and avalanche immunity are not required.

Compared with NSS5L60P5T1G and SS5P6L-M3/86A, STPS5L60SF provides the lowest forward voltage, best thermal resistance, and verified avalanche capability-making it optimal for high-efficiency, high-reliability 5 A DC/DC and adapter applications demanding manufacturability and transient robustness.

FAQ

Is STPS5L60SF suitable for synchronous rectification replacement?

No-it is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. However, its near-zero reverse recovery and low V_F make it a high-performance alternative to active synchronous solutions in cost-sensitive or layout-constrained designs where gate drive complexity is undesirable.

What is the minimum recommended PCB copper area for thermal management?

Per Figure 7 in DS12691, a minimum of 4 cm² of 35 µm copper on FR4 is required to achieve R_th(j-a) ≤ 45 °C/W. For continuous 5 A operation at 135 °C case temperature, ≥6 cm² is recommended to maintain T_j ≤ 150 °C with 20 °C ambient margin.

Does STPS5L60SF require a heatsink?

No discrete heatsink is required. The PSMC package is designed for conduction cooling via PCB copper. With ≥6 cm² thermal pad area and 2 oz copper, junction temperature stays within limit at full 5 A load without airflow-verified in ST's AN5088 thermal management guidelines.

Can STPS5L60SF be used in automotive applications?

It is qualified per AEC-Q101 for discrete semiconductors and rated for T_j = 150 °C, but lacks automotive-specific qualification documentation (e.g., PPAP, stress test reports) in public datasheets. Use in non-safety-critical 12 V subsystems (e.g., infotainment power) is feasible; consult ST's automotive support team for full qualification evidence.
