Product details

Overview

STPS5L60SY from STMicroelectronics is an automotive-grade power Schottky rectifier in SMC package, rated for 5 A average forward current, 60 V repetitive peak reverse voltage, and 150 °C maximum junction temperature, with typical forward voltage drop of 0.47 V at 5 A and 25 °C - used in low-voltage battery chargers and battery protection circuits in automotive power systems.

For engineers reviewing the STPS5L60SY datasheet, STPS5L60SY pinout, STPS5L60SY application, or STPS5L60SY equivalent, key selection criteria include forward voltage drop at operating current, thermal resistance (R_th(j-l) = 15 °C/W), avalanche capability (4000 W at 1 µs), AEC-Q101 qualification, and SMC package compatibility with high-power density PCB layouts.

Technical Context

This Schottky rectifier operates without minority-carrier storage, delivering negligible switching losses and enabling high-frequency operation in SMPS and inverters. Its low forward voltage (0.42–0.49 V across 25–125 °C at 5 A) directly reduces conduction loss, while specified avalanche capability supports transient surge resilience in automotive load-dump conditions.

The device features a thermally optimized SMC package with R_th(j-l) = 15 °C/W and supports ambient temperatures up to 125 °C at full 5 A rating (δ = 0.5). Reverse leakage remains ≤100 mA at 125 °C and full 60 V reverse bias, ensuring stable blocking performance under elevated thermal stress.

Key Specifications

Parameter	Value and Actual Design Meaning
IF(AV)	5 A - continuous DC output current capability at T_L = 100 °C, δ = 0.5, defining usable steady-state power delivery
VRRM	60 V - maximum repetitive reverse voltage before breakdown, setting system-level input/output voltage margin
VF (max)	0.53 V at 5 A, 25 °C - limits conduction loss to ≤2.65 W per diode at rated current, critical for thermal management
Rth(j-l)	15 °C/W - junction-to-leads thermal resistance enables direct heatsink mounting via leads, reducing board-level thermal bottleneck
IFSM	150 A (tp = 10 ms) - non-repetitive surge rating supporting automotive cold-crank and load-dump transients
PARM	4000 W (tp = 1 µs, Tj = 25 °C) - peak avalanche energy handling ensures robustness against inductive switching spikes
AEC-Q101	Qualified - validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock

Pinout & Package

STPS5L60SY uses the SMC (DO-214AB) surface-mount package: molded epoxy body, lead-free terminations, UL94 V0 rated, with 2.45 mm max height and 8.15 mm max width. Leads are plated for solderability and thermal conduction.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to input/source side; must be routed with low-inductance, high-current copper pour
Cathode	Forward current exit point	Connected to output/load side; serves as primary thermal path to PCB copper plane

Key Features

Feature	Design Value
Negligible switching losses	Zero reverse recovery charge (Q_rr ≈ 0), eliminating turn-off loss and EMI in >100 kHz SMPS designs
Low VF at high Tj	0.42 V typ. at 125 °C and 5 A - maintains efficiency in hot underhood locations without derating
Avalanche capability	4000 W peak power for 1 µs - protects against inductive kickback in motor control and solenoid drivers
Low thermal resistance	R_th(j-l) = 15 °C/W - allows direct thermal coupling to PCB copper, reducing need for external heatsinks
ECOPACK®2 compliance	Lead-free, halogen-free, RoHS-compliant construction meeting global automotive environmental mandates

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 MBR560FCT	Same SMC package, 5 A/60 V rating, but VF = 0.65 V (max) at 5 A - 23% higher conduction loss	Not AEC-Q101 qualified; limited to industrial/commercial automotive accessories	Select only if AEC-Q101 is not required and thermal margin permits higher VF
Vishay VS-50SQ060	TO-277 package (lower R_th(j-a)), 5 A/60 V, VF = 0.54 V (max) at 5 A, but no avalanche rating specified	Lacks documented avalanche capability - unsuitable for load-dump-prone battery protection paths	Prefer where board space allows TO-277 and surge immunity is managed externally

Compared with MBR560FCT and VS-50SQ060, STPS5L60SY uniquely combines AEC-Q101 qualification, 4000 W avalanche rating, and lowest VF (0.53 V max) in SMC - making it optimal for safety-critical, space-constrained automotive power rectification where thermal and transient robustness are co-prioritized.

FAQ

Is STPS5L60SY suitable for use in non-automotive applications?

Yes - its 150 °C junction rating, low VF, and robust avalanche capability make it viable for industrial SMPS, telecom power supplies, and high-reliability battery-powered equipment. However, AEC-Q101 qualification adds value only in automotive contexts; for commercial use, cost-optimized alternatives may be preferred.

What is the maximum PCB copper area needed to sustain 5 A continuous current at 100 °C ambient?

Per Figure 11 in the datasheet, 4.5 cm² of 35 µm copper under each lead achieves R_th(j-a) ≈ 40 °C/W, allowing 5 A at T_amb = 100 °C with T_j ≤ 150 °C. Thermal vias under cathode pads further improve heat spreading and reduce local hotspot risk.

Does STPS5L60SY have a specified reverse recovery time (t_rr)?

No - as a Schottky rectifier, it exhibits no minority-carrier storage, so t_rr is effectively zero. Datasheet confirms negligible switching losses and absence of reverse recovery charge (Q_rr ≈ 0), enabling clean high-frequency operation without snubbers.

Can STPS5L60SY replace a standard PN junction rectifier like 1N5408 in automotive circuits?

Yes, but only where reverse voltage does not exceed 60 V. STPS5L60SY offers lower VF (0.47 V vs. ~0.9 V), reduced heat generation, and faster switching - however, its lower reverse leakage at high temperature may affect certain sensing or bias networks relying on PN diode characteristics.
