Product details
Overview
SS13L from Taiwan Semiconductor is a 1 A, 30 V Schottky barrier surface-mount rectifier in Sub SMA package, featuring 0.500 V forward voltage at 1.0 A and 25°C, 30 A peak surge current, and -55°C to +150°C junction temperature range; used in DC-DC converters and AC adapters for high-efficiency low-loss rectification.
For engineers reviewing the SS13L datasheet, SS13L pinout, SS13L application, or SS13L equivalent, key selection criteria include its 30 V repetitive peak reverse voltage, 0.430 V typical forward voltage at 0.5 A, 400 µA max reverse leakage at 25°C, thermal resistance of 45°C/W (junction-to-lead), and Sub SMA mechanical compatibility with automated SMT placement.
Technical Context
The SS13L operates as a single-die Schottky rectifier with guard ring structure for overvoltage protection and meets JESD201 Class 2 whisker resistance. Its low VF and fast switching enable high-efficiency operation in high-frequency SMPS topologies without reverse recovery charge.
Designed for surface-mount assembly, it uses matte tin-plated leads compliant with J-STD-002 solderability and moisture sensitivity level 1 per J-STD-020. Polarity is marked by cathode band; case material meets UL 94V-0 flammability rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS13FL (Taiwan Semiconductor) | Same electrical specs; Sub SMA package with "F" suffix indicating halogen-free confirmation per IEC 61249-2-21 | No functional difference; selected when explicit halogen-free documentation is required for audit | Drop-in replacement if halogen-free certification is mandated in final product compliance package |
| MBR130LSFT1G (ON Semiconductor) | 30 V VRRM, 1 A IF, but VF = 0.45 V min @ 1 A; RθJA = 110°C/W vs. SS13L's 100°C/W | Slightly higher conduction loss and lower thermal efficiency in dense layouts | Valid alternative where ON Semi sourcing is preferred, but requires verification of thermal margin at full load |
Compared with SS13FL, the SS13L offers identical performance with standard halogen-free compliance; versus MBR130LSFT1G, SS13L provides lower VF and better junction-to-ambient thermal resistance, yielding higher efficiency in space-constrained power stages.

FAQ
What is the maximum junction temperature rating for SS13L?
The SS13L has a maximum junction temperature (TJ) rating of +150°C, confirmed in the Absolute Maximum Ratings table. This allows reliable operation in high-ambient environments such as enclosed power supplies or industrial enclosures. The SS13L maintains specified electrical performance up to this limit, and its thermal design must ensure junction temperature remains below +150°C under worst-case load and ambient conditions.
Does SS13L have a guard ring structure, and what benefit does it provide?
Yes, the SS13L incorporates a guard ring structure explicitly listed under FEATURES. This design enhances ruggedness against transient overvoltage events-such as line surges or inductive kickback-by preventing premature edge breakdown. As a result, the SS13L achieves a high dV/dt rating of 10,000 V/µs and improves reliability in unclamped or lightly snubbed switching circuits without requiring additional protection components.
What is the forward voltage of SS13L at 1.0 A and 25°C?
The forward voltage (VF) of SS13L is 0.500 V maximum at IF = 1.0 A and TJ = 25°C, per the ELECTRICAL SPECIFICATIONS table. This value is measured under pulsed conditions (PW = 0.3 ms) and defines the conduction loss in continuous operation. At 0.5 A, VF is 0.430 V maximum, supporting efficient light-load performance in adaptive duty-cycle designs.
Is SS13L compatible with lead-free reflow soldering processes?
Yes, SS13L is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated at Level 1 per J-STD-020-meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into standard Pb-free reflow profiles (e.g., JEDEC J-STD-020D peak of 260°C) without baking.
What packaging option is available for SS13L?
SS13L is supplied in tape-and-reel packaging, with 10,000 units per reel, as specified in the ORDERING INFORMATION section. This format supports high-speed automated pick-and-place assembly and is compatible with standard SMT feeders. No alternate packaging (e.g., bulk or tube) is listed for SS13L in the official documentation.
