Product details

Overview

STPS2L60AY from STMicroelectronics is an AEC-Q101-qualified automotive Schottky rectifier in SMA package, rated for 2 A average forward current, 60 V repetitive peak reverse voltage, and 150 °C maximum junction temperature. It delivers low forward voltage drop (0.55 V at 2 A, 125 °C) with negligible switching losses, enabling high-efficiency DC/DC conversion in battery chargers and low-voltage inverters.

For engineers reviewing the STPS2L60AY datasheet, STPS2L60AY pinout, STPS2L60AY application, or STPS2L60AY equivalent, key selection criteria include avalanche-rated surge capability (75 A, 10 ms), thermal resistance (25 °C/W junction-to-lead), and ECOPACK®2-compliant lead-free packaging for automotive-grade reliability.

Technical Context

This Schottky diode operates as a unidirectional power rectifier with metal–semiconductor junction architecture, eliminating minority-carrier storage delay and enabling zero-recovery switching. Its low VF and high dV/dt rating (10,000 V/µs) support stable operation in high-frequency (>100 kHz) SMPS topologies without snubbers.

The device features specified avalanche energy handling (1600 W, 1 µs pulse at 25 °C) and is characterized across -40 to +150 °C junction temperature range. Thermal design relies on validated R_th(j-l) = 25 °C/W and copper-area-dependent R_th(j-a) curves up to 5 cm² per lead.

Key Specifications

Parameter	Value and Actual Design Meaning
IF(AV)	2 A - Sustained DC output current capability at TL = 115 °C with 50% duty cycle
VRRM	60 V - Maximum reverse blocking voltage before breakdown; defines system input voltage ceiling
VF(max)	0.55 V @ 2 A, 125 °C - Directly determines conduction loss (P ≈ 0.43×IF + 0.06×IF²)
IFS M	75 A @ 10 ms sinusoidal - Supports short-circuit and startup surge without failure
Rth(j-l)	25 °C/W - Enables thermal modeling from junction to PCB lead; critical for heatsinkless layout
Tj(max)	+150 °C - Junction temperature limit ensuring long-term reliability under automotive transients
dV/dt	10,000 V/µs - Confirmed immunity to fast voltage transients in noisy automotive environments

Pinout & Package

IC Role / Device Role / Timing Role: Secondary-side Schottky rectifier replacing conventional diodes to reduce conduction loss and improve light-load efficiency.

Use Value: 0.55 V VF at 125 °C maintains <1.2 W dissipation at 2 A, avoiding forced cooling.

Use Scenario: 24 V input inverter supplying 12 V auxiliary rail for HVAC actuators and window lift motors.

IC Role / Device Role / Timing Role: Freewheeling diode in half-bridge output stage.

Use Value: 75 A IFSM withstands motor stall currents; dV/dt rating prevents false triggering during PWM edge transitions.

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 NSS2L60W1T1G	Same SMA package, 2 A/60 V rating, but VF = 0.62 V (typ) at 2 A/25 °C; no AEC-Q101 certification	Not qualified for automotive safety-critical systems; suitable only for industrial or consumer DC/DC	Select only if AEC-Q101 is not required and higher VF is acceptable in thermal budget
Vishay VS-2EY60-M3/54	SMA package, 2 A/60 V, VF = 0.57 V (max) at 2 A/125 °C; AEC-Q101 qualified; Rth(j-l) = 28 °C/W	Higher thermal resistance reduces power handling margin at same PCB copper area	Prefer when alternate sourcing is needed and thermal margin allows 3 °C/W penalty

Compared with NSS2L60W1T1G and VS-2EY60-M3/54, STPS2L60AY offers the lowest VF at elevated temperature and best thermal resistance, making it optimal for thermally constrained automotive modules where efficiency and junction temperature control are critical.

FAQ

Is STPS2L60AY suitable for synchronous rectification?

No. STPS2L60AY is a passive Schottky diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively switched. It functions as a freewheeling or output rectifier in non-synchronous topologies like standard flyback or forward converters where simplicity and cost outweigh efficiency gains from synchronous operation.

What is the maximum allowable PCB copper area per lead for thermal performance?

Per Figure 10 in the datasheet, R_th(j-a) improves with copper surface area: at 5 cm² per lead, R_th(j-a) drops to ~40 °C/W. No absolute maximum is defined, but practical limits are set by board real estate and adjacent component clearance. For 2 A continuous operation, ≥2 cm² per lead is recommended to maintain Tj ≤ 125 °C at 70 °C ambient.

Does STPS2L60AY have a specified reverse recovery time (trr)?

No - STPS2L60AY is a Schottky diode with majority-carrier conduction; it has no reverse recovery time or Qrr parameter. The datasheet confirms "negligible switching losses" and absence of minority-carrier storage, making trr undefined and irrelevant for this device. This eliminates turn-off loss and associated EMI in high-frequency designs.

Can STPS2L60AY replace a standard PN junction rectifier in an existing design?

Yes, provided VR and IF ratings are met and layout accommodates SMA footprint. Its lower VF reduces conduction loss and heat generation, but note: Schottky diodes exhibit higher reverse leakage (up to 10 mA at 100 °C), which may affect standby power in ultra-low-power systems. Verify IR impact in your specific bias conditions before substitution.
