Product details

Overview

STPS2L60A from STMicroelectronics is a 60 V, 2 A low-drop power Schottky rectifier in SMA package, designed 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 75 A non-repetitive surge current, and features avalanche rating and ECOPACK2 compliance.

For engineers reviewing the STPS2L60A datasheet, STPS2L60A pinout, STPS2L60A application, or STPS2L60A equivalent, key selection criteria include forward voltage drop at operating temperature, thermal resistance (R_th(j-l) = 25 °C/W), peak reverse voltage rating, surge current capability, and surface-mount package compatibility with automated assembly.

Technical Context

This Schottky rectifier operates as a unidirectional power switching device with zero minority-carrier storage, enabling negligible switching losses and high-frequency operation up to several MHz. Its metal–semiconductor junction yields low forward voltage (VF) and fast recovery without reverse recovery charge (Q_rr ≈ 0).

The device is rated for 150 °C maximum junction temperature and optimized for conduction-dominated loss environments. Thermal performance depends on PCB copper area and lead length - R_th(j-a) drops from 100 °C/W (DO-41) to 40 °C/W (SMB Flat with 2.5 cm² Cu) under defined mounting conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in DC-DC flyback or buck output stages.
I_F(AV)	2 A - Average forward current at TL = 115 °C (SMA); sets continuous output current capability in low-voltage SMPS outputs.
V_F(typ.)	0.51 V @ 2 A, 125 °C - Low conduction loss enables >95% efficiency in 5–12 V output rails and extends battery runtime in portable chargers.
I_FSM	75 A @ 10 ms - Surge withstand capability protects against inrush and transient overloads in auxiliary power and set-top box supplies.
R_th(j-l)	25 °C/W - Junction-to-lead thermal resistance (SMA); determines required PCB copper area and heatsinking for thermal stability.
T_j(max)	150 °C - Maximum junction temperature; allows operation in compact, sealed enclosures without active cooling.
ECOPACK2	Compliant - Halogen-free, RoHS-compliant packaging meeting industrial environmental requirements for global OEM production.

Pinout & Package

STPS2L60A uses the SMA (DO-214AC) surface-mount package: 2-pin, cathode-banded, epoxy-molded, UL94 V0 rated. Dimensions: D = 2.25–2.90 mm, E = 4.80–5.35 mm, L = 0.75–1.50 mm.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input current terminal	Connected to switching node (e.g., MOSFET drain in buck converter); carries full load current during conduction phase.
Cathode	Output current terminal	Connected to output filter capacitor and load; polarity band identifies this terminal; must be routed with low-inductance trace.

Key Features

Feature	Design Value
Negligible switching losses	No reverse recovery charge (Q_rr ≈ 0), eliminating turn-off loss and EMI in >100 kHz converters.
Low forward voltage drop	V_F = 0.51 V @ 2 A, 125 °C reduces conduction loss by ~30% vs. standard silicon diodes, improving thermal margin.
Avalanche rated	Rated for 115 W repetitive peak avalanche power (t_p = 10 µs, T_j = 125 °C), enhancing robustness against inductive kickback.
Surface mount miniature package	SMA footprint (5.43 × 2.63 mm) supports high-density PCB layouts and automated reflow assembly without axial lead trimming.
ECOPACK2 compliance	Halogen-free, lead-free, RoHS-compliant construction meets IEC 61249-2-21 and JEDEC J-STD-020 standards.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS26 (ON Semiconductor)	V_F = 0.75 V @ 2 A, 25 °C; R_th(j-l) = 30 °C/W; no avalanche rating.	Lacks repetitive avalanche capability; higher V_F increases conduction loss in thermally constrained designs.	Acceptable where surge immunity is not critical and thermal margin exceeds 10 °C.
SB260 (Vishay)	V_F = 0.65 V @ 2 A, 25 °C; I_FSM = 50 A; SMB package (R_th(j-l) = 15 °C/W).	Lower surge rating and higher V_F, but superior thermal performance due to SMB Flat package.	Preferred when board space permits SMB footprint and thermal design prioritizes junction-to-lead dissipation.

Compared with SS26 and SB260, STPS2L60A offers the lowest V_F at elevated temperature (0.51 V @ 125 °C), integrated avalanche ruggedness, and SMA package compatibility with legacy footprints - making it optimal for high-reliability, thermally sensitive 60 V-class SMPS outputs.

FAQ

What is the maximum junction temperature and how does it affect reliability?

The STPS2L60A has a maximum junction temperature (T_j(max)) of 150 °C. Operating continuously near this limit accelerates parametric drift and reduces long-term reliability. Derating guidelines require maintaining T_j ≤ 125 °C for 10-year lifetime in industrial applications, achievable via adequate PCB copper area and ambient temperature control.

Is STPS2L60A suitable for synchronous rectification circuits?

No - STPS2L60A is a passive Schottky diode, not a synchronous rectifier IC or MOSFET-based solution. It functions as an autonomous unidirectional conductor and cannot be actively controlled or gated. For synchronous designs, discrete N-channel MOSFETs with gate drivers are required.

How does the SMA package compare thermally to SMB Flat or DO-41 variants?

STPS2L60A (SMA) has R_th(j-l) = 25 °C/W, versus 15 °C/W for SMB Flat and 30 °C/W for DO-41. The SMA offers better thermal conduction than DO-41 but less than SMB Flat. However, its smaller footprint saves board space, and its thermal performance is sufficient for ≤2 A continuous loads with ≥1 cm² copper per lead.

Does STPS2L60A have a specified reverse recovery time (t_rr)?

No - as a Schottky diode, STPS2L60A exhibits no minority-carrier storage and therefore has no measurable reverse recovery time. Its switching behavior is governed solely by junction capacitance (C_j ≈ 200 pF at 4 V), enabling clean, lossless turn-off in high-frequency converters without reverse recovery spikes.
