Product details
Overview
SSA23L-E3/5AT from Vishay General Semiconductor is a high-current-density surface-mount Schottky rectifier in SMA (DO-214AC) package, rated for 30 V repetitive peak reverse voltage, 2.0 A average forward current, and 60 A non-repetitive surge current. It delivers low forward voltage drop (0.38 V typ. at 2.0 A, TJ = 125 °C), enabling high-efficiency DC/DC conversion in space-constrained power stages.
For engineers reviewing the SSA23L-E3/5AT datasheet, SSA23L-E3/5AT pinout, SSA23L-E3/5AT application, or SSA23L-E3/5AT equivalent, key selection criteria include its 30 V VRRM rating, 150 °C max junction temperature, AEC-Q101 qualification availability (HE3 variant), MSL Level 1 moisture sensitivity, and RoHS-compliant matte tin plating - all critical for automotive and industrial power supply designs.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with integrated guardring for enhanced overvoltage robustness and reduced leakage under thermal stress. Its low VF and high IFSM support high-frequency switching topologies where conduction loss minimization and transient surge resilience are essential.
The device operates across -65 °C to +150 °C junction temperature range and exhibits 110 °C/W typical junction-to-ambient thermal resistance on standard FR-4 PCBs. Its 10,000 V/μs dV/dt rating ensures stable operation during fast-switching transients in synchronous rectification and freewheeling paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SSA23L-E3/61T | Same die and electrical specs; differs only in tape-and-reel packaging (1800 pcs, 7″ reel vs. 7500 pcs, 13″ reel) | Identical functional use; suited for lower-volume prototyping or smaller SMT line setups | Select based on production volume and feeder compatibility rather than performance |
| SSA24-E3/5AT | Higher 40 V VRRM rating; slightly higher VF (0.42 V typ. @ 2.0 A, TJ = 125 °C); same package and thermal specs | Better suited for 24 V nominal systems with higher transient margins; less optimal for 12 V or lower outputs due to increased conduction loss | Choose SSA24-E3/5AT only when system VRRM requirement exceeds 30 V; otherwise SSA23L-E3/5AT offers superior efficiency |
Compared with SSA23L-E3/5AT, the SSA23L-E3/61T provides identical electrical behavior in a smaller reel format ideal for evaluation and low-run builds, while the SSA24-E3/5AT trades 10 V higher blocking capability for ~10 % higher forward loss - making SSA23L-E3/5AT the preferred choice for 12 V and sub-12 V high-efficiency power rails.

FAQ
What is the maximum junction temperature rating for SSA23L-E3/5AT?
The SSA23L-E3/5AT has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay's thermal characterization data. This allows reliable operation in high-temperature environments such as under-hood automotive electronics or enclosed industrial power supplies. The device maintains specified electrical performance up to this limit, provided thermal design accounts for its 110 °C/W RθJA on standard PCBs. Derating curves in the datasheet confirm usable current capacity at elevated temperatures.
Is SSA23L-E3/5AT RoHS-compliant and lead-free?
Yes, the SSA23L-E3/5AT is RoHS-compliant and lead-free, as confirmed by the "E3" suffix per Vishay's ordering nomenclature. Its matte tin-plated terminals meet J-STD-002 solderability requirements and JESD 22-B102 for intermetallic reliability. The molding compound complies with UL 94 V-0 flammability standards, and the entire construction satisfies EU Directive 2011/65/EU without exemptions.
Does SSA23L-E3/5AT have AEC-Q101 qualification?
The base SSA23L-E3/5AT is commercial-grade and not AEC-Q101 qualified. However, the HE3-suffix variant (e.g., SSA23LHE3_A/I) is explicitly AEC-Q101 qualified per the Vishay datasheet. For automotive applications requiring stress-tested reliability, users must specify the HE3 version - the E3 suffix alone does not imply automotive qualification. Always verify part marking and packaging code before deployment in automotive systems.
What is the forward voltage drop of SSA23L-E3/5AT at 2.0 A and 125 °C?
The typical forward voltage drop (VF) of SSA23L-E3/5AT is 0.38 V at 2.0 A and TJ = 125 °C, as specified in the Electrical Characteristics table. This value reflects real-world conduction loss under thermal stress and is critical for calculating efficiency in high-temperature operating conditions. The maximum VF under those conditions is 0.42 V, providing a clear design margin for worst-case power dissipation analysis.
What package type does SSA23L-E3/5AT use, and what are its key mechanical features?
SSA23L-E3/5AT uses the SMA (DO-214AC) surface-mount package, measuring 4.93 mm × 3.99 mm × 2.29 mm. Key mechanical features include UL 94 V-0 rated epoxy molding, cathode identification via color band, matte tin-plated leads for solderability, and compliance with J-STD-020 MSL Level 1 - permitting reflow up to 260 °C without pre-baking. Mounting pad dimensions are documented in the official Vishay outline drawing.
