Product details
Overview
SSL13H from Taiwan Semiconductor is a 1A, 30V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, designed for low-loss freewheeling and reverse battery protection in automotive lighting and DC/DC converters. It features AEC-Q101 qualification, 50A peak surge current rating, 0.39V max forward voltage at 1A, and junction temperature range of –55°C to +125°C.
For engineers reviewing the SSL13H datasheet, SSL13H pinout, SSL13H application, or SSL13H equivalent, key selection criteria include its 30V repetitive peak reverse voltage, moisture sensitivity level 1 compliance, guard ring–enhanced overvoltage robustness, and suitability for automated SMT assembly in space-constrained automotive power rails.
Technical Context
The SSL13H operates as a single-die Schottky rectifier with unidirectional conduction and cathode-band polarity indication. Its thermal design supports 28°C/W junction-to-lead resistance and 88°C/W junction-to-ambient resistance under standard mounting conditions.
Electrical behavior is defined by a maximum 0.39V forward voltage at 1A/25°C, 200μA reverse leakage at rated 30V and 25°C, and 50mA leakage at 100°C - enabling stable operation in thermally demanding automotive ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in reverse-biased freewheeling or reverse-polarity protection circuits |
| IF | 1 A - Continuous forward current rating; determines steady-state power dissipation and heatsink requirements |
| IFSM | 50 A - Non-repetitive surge current capacity; enables survival during load dump or inductive kick events |
| VF (max) | 0.39 V @ 1A, 25°C - Low conduction loss directly reduces power stage inefficiency and thermal stress |
| TJ Range | –55°C to +125°C - Qualified for under-hood automotive use without derating below –40°C ambient |
| RθJL | 28 °C/W - Enables accurate junction temperature estimation from lead temperature measurements during validation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB130-TB (Comchip) | Same DO-214AC package, 30V VRRM, but 0.45V VF max @ 1A - 15% higher conduction loss | Lacks AEC-Q101 qualification; not recommended for automotive production | Acceptable for industrial DC/DC where qualification isn't mandated |
| SS13HE3/5AT (Vishay) | Identical 30V/1A rating, AEC-Q101 qualified, but 0.42V VF max - slightly higher loss than SSL13H | Same automotive-grade reliability; different marking and tape/reel packaging (5,000 vs 7,500 pcs/reel) | Drop-in substitute where Vishay supply chain preference applies |
Compared with SB130-TB and SS13HE3/5AT, the SSL13H delivers the lowest forward voltage among AEC-Q101–qualified 30V/1A Schottky rectifiers in DO-214AC, yielding measurable thermal margin in sealed automotive enclosures and reducing system-level cooling requirements.

FAQ
What is the maximum repetitive peak reverse voltage rating for SSL13H?
The SSL13H has a maximum repetitive peak reverse voltage (VRRM) rating of 30 V, as specified in the absolute maximum ratings table. This value defines the highest reverse-bias voltage the device can block continuously without breakdown under normal operating conditions, making it suitable for 24V automotive systems with transient overvoltage margins.
Is SSL13H qualified for automotive applications?
Yes, SSL13H is AEC-Q101 qualified, confirming its reliability for automotive electronic systems. The qualification includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), ensuring robust performance in under-hood environments where SSL13H is commonly deployed.
What is the forward voltage drop of SSL13H at rated current?
The SSL13H exhibits a maximum forward voltage (VF) of 0.39 V at 1 A forward current and 25°C junction temperature. This low VF contributes to reduced conduction losses and improved efficiency in power conversion stages where SSL13H serves as a freewheeling or output rectifier.
Does SSL13H require special handling during PCB assembly?
No - SSL13H has moisture sensitivity level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without baking. Its matte tin-plated leads are solderable per J-STD-002, supporting standard lead-free reflow profiles used for DO-214AC packages.
What package type does SSL13H use, and what are its key mechanical features?
SSL13H uses the DO-214AC (SMA) surface-mount package. Key mechanical features include UL 94V-0 molded compound, cathode band polarity marking, 0.066 g typical weight, and compliance with JEDEC DO-214 variation AC outline dimensions - all verified in TSC's package drawing HQ2SD07-DO214SMC-034 REV A.
