Product details
Overview
SS215LH from Taiwan Semiconductor is a 2 A, 150 V Schottky barrier surface-mount rectifier in Sub SMA package, featuring 0.95 V forward voltage at 2 A and 100 µA reverse leakage at 25°C, designed for reverse battery protection and DC/DC converters in automotive lighting systems.
For engineers reviewing the SS215LH datasheet, SS215LH pinout, SS215LH application, or SS215LH equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, 50 A surge rating, AEC-Q101 qualification, low VF at high IF, and thermal resistance of 17 °C/W junction-to-lead.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 150 V VRRM and 5 mA IR at 125°C support operation in high-temperature automotive environments.
The device achieves high efficiency via low conduction loss (VF = 0.95 V @ 2 A) and fast switching with dV/dt rating of 10,000 V/µs, enabling use in high-frequency inverters and freewheeling paths where minimal recovery loss is critical.
Key Specifications

|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage for reliable operation in 12–48 V automotive systems with load dump transients |
| IF | 2 A continuous - rated average forward current enabling compact DC/DC converter designs without forced cooling |
| IFSM | 50 A - peak non-repetitive surge current handling capability for motor startup or inrush events |
| VF | 0.95 V @ 2 A, 25°C - low forward drop minimizing power loss and thermal stress in high-current paths |
| RθJL | 17 °C/W - low junction-to-lead thermal resistance supporting PCB-level heat dissipation without heatsinks |
| TJ max | 150 °C - extended junction temperature rating allowing operation in under-hood automotive locations |
| IR | 100 µA @ VR = 150 V, 25°C - low leakage preserving battery life in reverse-polarity protection circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY15-M3/5BT | Same 2 A / 150 V rating, but TO-277 package (larger footprint, higher RθJA = 90 °C/W) | Less suitable for ultra-compact automotive modules due to 30% larger PCB area and lower thermal efficiency | Prefer SS215LH when space-constrained Sub SMA layout and lower thermal resistance are required |
| ON Semiconductor SB2150-E3/54 | 2 A / 150 V, but VF = 0.92 V @ 2 A and IR = 200 µA @ 25°C - higher leakage compromises reverse-battery hold-off | Acceptable for general-purpose DC/DC but not recommended for long-duration battery disconnect scenarios | SS215LH offers superior leakage performance (100 µA vs. 200 µA) for safety-critical polarity protection |
Compared with VS-2EY15-M3/5BT and SB2150-E3/54, the SS215LH delivers optimal balance of compact Sub SMA packaging, lowest IR for reverse-battery integrity, and best junction-to-lead thermal path - making it preferred for space- and reliability-constrained automotive subsystems.

FAQ
What is the maximum junction temperature rating for the SS215LH?
The SS215LH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows sustained operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit using its 17 °C/W RθJL.
Is the SS215LH suitable for reverse battery protection in 24 V commercial vehicles?
Yes, the SS215LH is suitable for reverse battery protection in 24 V commercial vehicles. Its 150 V VRRM, 100 µA IR at 25°C, and AEC-Q101 qualification ensure robust blocking during reverse connection events and compatibility with ISO 16750-2 electrical load dump profiles up to 120 V.
What is the forward voltage of the SS215LH at 2 A and 125°C?
The SS215LH forward voltage increases with temperature; while the datasheet specifies 0.95 V at 25°C, typical VF rises to approximately 0.85 V at 125°C due to Schottky diode negative temperature coefficient. This behavior is confirmed in Figure 4 (Typical Forward Characteristics) of the SS22LH–SS215LH datasheet.
Does the SS215LH have a halogen-free construction?
Yes, the SS215LH is halogen-free according to IEC 61249-2-21, and fully RoHS compliant. The molding compound contains no brominated or chlorinated flame retardants, meeting stringent environmental requirements for automotive electronics supply chains.
What is the moisture sensitivity level (MSL) of the SS215LH?
The SS215LH has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH and subjected to standard SMT reflow profiles without prior baking - simplifying manufacturing logistics and reducing process risk.
