Product details
Overview
SS215LWH from Taiwan Semiconductor is a 2 A, 150 V Schottky barrier surface-mount rectifier in SOD-123W package, featuring 0.95 V max forward voltage at 2 A and 10 µA max reverse leakage at rated VR, designed for automotive-grade DC/DC converters and reverse battery protection circuits.
For engineers reviewing the SS215LWH datasheet, SS215LWH pinout, SS215LWH application, or SS215LWH equivalent, key selection criteria include its AEC-Q101 qualification, 50 A peak surge current rating, junction-to-lead thermal resistance of 25°C/W, and moisture sensitivity level 1 compliance for high-reliability automotive and industrial power systems.
Technical Context
The SS215LWH employs a single-die Schottky structure optimized for low forward voltage drop and fast switching, enabling high-efficiency operation in 100–500 kHz DC/DC topologies. Its guard ring design provides over-voltage robustness while maintaining tight thermal performance with RθJL = 25°C/W.
Rated for continuous operation up to +150°C junction temperature and qualified per AEC-Q101, the device supports automotive lighting and infotainment power rails where stable reverse recovery and low conduction loss are critical under transient load conditions.
Key Specifications

| Forward Voltage (VF) | ≤ 0.95 V @ 2 A, 25°C - reduces conduction loss by ~30% vs. comparable Si diodes |
| Reverse Leakage (IR) | ≤ 10 µA @ 150 V - ensures minimal standby power loss in always-on vehicle modules |
| Surge Current (IFSM) | 50 A (8.3 ms half-sine) - withstands cold-crank and load-dump events |
| Junction Temp (TJ) | −55°C to +150°C - meets extended temperature requirements for under-hood electronics |

FAQ
What is the maximum junction temperature rating for the SS215LWH?
The SS215LWH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows continuous operation in under-hood environments where ambient temperatures reach 105°C, provided thermal design maintains junction temperature below this limit. The SS215LWH's RθJL = 25°C/W enables effective heat transfer to PCB copper, making it suitable for thermally constrained automotive modules.
Is the SS215LWH pin-compatible with other parts in the SS2xLWH series?
Yes, all SS2xLWH variants-including SS24LWH, SS26LWH, SS210LWH, SS215LWH, and SS220LWH-share identical SOD-123W package dimensions, pinout, and solder pad layout. The only differences are VRRM rating and associated electrical parameters (e.g., VF and IR), allowing direct substitution during design-in based on voltage requirements without PCB revision.
Does the SS215LWH require special handling during reflow soldering?
No, the SS215LWH has moisture sensitivity level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and processed using standard lead-free reflow profiles without baking or dry-pack requirements. Its matte tin-plated leads ensure reliable solderability per J-STD-002, supporting high-yield automated assembly in automotive manufacturing lines.
What is the forward voltage specification for the SS215LWH at 2 A and 125°C?
The SS215LWH forward voltage (VF) is specified as ≤0.95 V at 2 A and 25°C. While no max value is given at 125°C, typical curves show VF decreases with rising temperature-approximately 0.88 V at 125°C. Designers should reference Figure 10 in the SS24LWH–SS220LWH datasheet (Version B2301, page 4) for exact VF vs. TJ behavior across operating conditions.
How does the guard ring feature improve reliability in the SS215LWH?
The guard ring in the SS215LWH enhances edge termination robustness, preventing premature avalanche breakdown at the die periphery under repetitive over-voltage transients. This design allows the SS215LWH to sustain rated VRRM (150 V) with margin during load-dump events in automotive 24 V systems, reducing field failure risk without requiring external TVS clamping in many applications.
