Product details

Overview

SL13-E3/5AT from Vishay General Semiconductor is a low VF surface-mount Schottky rectifier in SMA (DO-214AC) package, rated for 30 V repetitive peak reverse voltage, 1.5 A average forward current, and 50 A surge capability. It delivers 0.34 V forward voltage at 1.0 A and 125 °C, enabling high-efficiency DC/DC converters and polarity protection circuits in space-constrained power supplies.

For engineers reviewing the SL13-E3/5AT datasheet, SL13-E3/5AT pinout, SL13-E3/5AT application, or SL13-E3/5AT equivalent, key selection criteria include its 30 V V_RRM, 0.34 V V_F @ 1.0 A / 125 °C, 50 A I_FSM, AEC-Q101 qualification availability, and SMA package thermal resistance of 28 °C/W junction-to-lead.

Technical Context

This Schottky rectifier uses a planar epitaxial construction with guardring for overvoltage protection and operates as a single-anode/cathode unidirectional device. Its low 0.34 V forward drop at 1.0 A and 125 °C directly reduces conduction losses in high-frequency switching topologies.

The device exhibits 10,000 V/μs dV/dt rating and 0.2 mA reverse leakage at 25 °C, supporting reliable operation in fast-switching freewheeling and synchronous rectification roles where low recovery charge and minimal reverse recovery time are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	30 V - maximum repetitive reverse blocking voltage; defines safe operating limit in DC/DC converter output stage
I_F(AV)	1.5 A at T_L = 105 °C - continuous forward current rating on standard PCB pad; sets power handling in compact layouts
V_F	0.34 V @ 1.0 A, 125 °C - low conduction loss enables >92 % efficiency in 3.3–5 V output buck converters
I_FSM	50 A - withstands inrush and transient surges without degradation; supports robust input protection
R_θJL	28 °C/W - low junction-to-lead thermal resistance allows direct heat transfer to PCB copper, easing thermal design
T_J max.	125 °C - maximum operating junction temperature; compatible with automotive under-hood ambient conditions

Pinout & Package

Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode identified by color band.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to input/source side in rectification; requires adequate copper pour for thermal dissipation
Cathode	Forward current exit point; marked with band	Connected to load/output side; polarity-sensitive placement prevents reverse-bias failure

Key Features

Feature	Design Value
Guardring structure	Enhances ruggedness against transient overvoltage events without external snubbers
Low profile SMA package	0.078" height enables use in ultra-thin power modules and portable electronics
MSL Level 1 rating	Allows unlimited floor life and reflow up to 260 °C peak-no baking required before assembly
Very low forward voltage	0.23 V @ 0.1 A / 125 °C minimizes dropout in low-voltage hold-up and battery charging paths

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS13H-E3/57T	Same SMA package, 30 V V_RRM, but rated 1.0 A I_F(AV); lower surge rating (30 A)	Lower current capacity limits use in >1 A continuous loads	Select SL13-E3/5AT when full 1.5 A derated current and 50 A surge margin are required
SB130-E3/52T	DO-41 through-hole package; identical 30 V/1.5 A ratings but higher V_F (0.45 V @ 1 A)	Requires through-hole assembly and larger board area; unsuitable for automated SMT lines	Choose SL13-E3/5AT for SMT production, tighter thermal management, and lower forward loss

Compared with SS13H-E3/57T and SB130-E3/52T, SL13-E3/5AT uniquely combines 1.5 A average current, 50 A surge capability, 0.34 V forward drop, and RoHS-compliant SMA packaging-making it optimal for high-density, high-reliability SMT power conversion designs.

FAQ

What is the maximum junction temperature for SL13-E3/5AT?

The SL13-E3/5AT has a maximum operating junction temperature of +125 °C, verified per the Vishay datasheet revision 23-Apr-2020. This rating allows deployment in under-hood automotive environments and enclosed industrial power supplies where ambient temperatures approach 85 °C. Derating curves confirm 1.5 A I_F(AV) is maintained up to 105 °C lead temperature, and SL13-E3/5AT must be thermally anchored to sufficient copper area to avoid exceeding T_J max.

Is SL13-E3/5AT RoHS-compliant and halogen-free?

Yes, SL13-E3/5AT is RoHS-compliant per the "E3" suffix definition in the Vishay documentation, and its molding compound meets UL 94 V-0 flammability rating. The datasheet confirms compliance with material categorization per Vishay document 99912. SL13-E3/5AT contains no intentionally added halogens and satisfies JEDEC J-STD-609A Class 1 requirements for halogen content.

What does the "5AT" in SL13-E3/5AT indicate?

The "5AT" in SL13-E3/5AT is the preferred package code denoting 13-inch diameter plastic tape and reel packaging with 7500 units per reel. This format is optimized for high-volume SMT pick-and-place equipment. The "E3" suffix confirms RoHS compliance and commercial-grade qualification, while SL13-E3/5AT shares identical electrical and thermal specifications with other SL13-E3 variants such as SL13-E3/61T.

Does SL13-E3/5AT have AEC-Q101 qualification?

No, SL13-E3/5AT is not AEC-Q101 qualified. That qualification applies only to variants with the "HE3" prefix (e.g., SL13HE3_B/H). SL13-E3/5AT is commercial-grade and meets MSL Level 1 and JESD 201 Class 2 whisker testing, but it lacks the extended temperature cycling, humidity bias, and high-temperature operating life validation required for automotive-grade release. For AEC-Q101 needs, specify SL13HE3_B/I or equivalent.

What is the thermal resistance from junction to ambient for SL13-E3/5AT?

The datasheet specifies R_θJA = 88 °C/W for SL13-E3/5AT under standard test conditions (PCB mounted on 0.2" × 0.2" copper pads). However, its R_θJL = 28 °C/W is more design-relevant-indicating efficient heat transfer from junction to leads. For accurate thermal design, SL13-E3/5AT should be placed on ≥5 mm × 5 mm copper areas with multiple thermal vias to internal ground planes to approach the 28 °C/W path.
