Product details
Overview
SS215FSH from Taiwan Semiconductor is a 2 A, 150 V Schottky barrier surface-mount rectifier in SOD-128 package, featuring low forward voltage (0.81 V at 2 A, 25°C), high surge capability (50 A IFSM), and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in compact DC/DC converters and onboard power supplies.
For engineers reviewing the SS215FSH datasheet, SS215FSH pinout, SS215FSH application, or SS215FSH equivalent, key selection criteria include its 150 V reverse rating, thermal resistance (RθJL = 18 °C/W), junction capacitance (48 pF), and automotive qualification - all critical for high-efficiency, space-constrained power conversion designs.
Technical Context
The SS215FSH implements a single-die Schottky structure optimized for low conduction loss and fast switching in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) topologies. Its 150 V VRRM rating enables use in 48 V and 60 V bus-derived systems with margin against transients.
Thermal performance is defined by RθJL = 18 °C/W and RθJA = 75 °C/W on a 5 mm × 5 mm Cu pad PCB, supporting sustained 2 A operation up to +125°C junction temperature. Reverse leakage remains ≤10 µA at 25°C and ≤5 mA at 125°C under rated VR.
Key Specifications

| VF @ 2 A, 25°C | 0.81 V max - reduces conduction loss to <1.6 W per device at full load |
| IFSM | 50 A (8.3 ms) - withstands inrush and short-circuit events in SMPS outputs |
| CJ | 48 pF @ 1 MHz, 4 V - minimizes switching node ringing and EMI in high-frequency converters |
| TJ max | +150 °C - enables operation in under-hood automotive environments |

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 | Same 150 V VRRM, 2 A IF, but TO-277A package (larger footprint, higher RθJA = 90 °C/W) | Less suitable for ultra-thin PCBs; requires larger thermal pad area | Choose when legacy TO-277A layout exists or higher surge margin (60 A IFSM) is needed |
| ON Semiconductor SB2150 | 150 V VRRM, 2 A IF, SOD-123FL package; VF = 0.85 V @ 2 A, 25°C; no AEC-Q101 qualification | Not qualified for automotive; lower thermal performance (RθJL = 25 °C/W) | Choose for cost-sensitive industrial adapters where automotive qualification is unnecessary |
Compared with VS-2EY15-M3 and SB2150, the SS215FSH uniquely combines AEC-Q101 qualification, SOD-128 compactness, and 18 °C/W junction-to-lead thermal resistance - making it optimal for automotive and space-constrained industrial DC/DC converters requiring long-term reliability.

FAQ
What is the maximum junction temperature rating for the SS215FSH?
The SS215FSH has a maximum junction temperature (TJ) of +150°C, enabling reliable operation in under-hood automotive environments and thermally dense industrial power modules. This rating is maintained across its full operating current range and is validated per AEC-Q101 stress testing protocols. The SS215FSH must be mounted on a PCB with adequate copper area to ensure thermal resistance stays within specification.
Is the SS215FSH pin-compatible with other parts in the SS2xFSH series?
Yes, all SS2xFSH devices - including SS24FSH, SS26FSH, SS210FSH, SS215FSH, and SS220FSH - share identical SOD-128 package dimensions, pinout, and mechanical footprint. This allows direct substitution based on required VRRM without PCB redesign. The SS215FSH specifically provides 150 V reverse blocking while maintaining the same 2 A current rating and thermal characteristics as its siblings.
Does the SS215FSH require special handling due to moisture sensitivity?
No, the SS215FSH is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it has unlimited floor life and does not require dry pack storage or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates yield risk associated with moisture-induced popcorning during assembly - a key advantage over many competing Schottky rectifiers.
What is the typical forward voltage of the SS215FSH at elevated temperature?
At 2 A and +125°C junction temperature, the SS215FSH exhibits a maximum forward voltage of 0.80 V, with typical value of 0.67 V. This low VF drift with temperature ensures stable efficiency in high-ambient environments such as engine compartments or enclosed power supplies, distinguishing it from silicon diodes that exhibit significant VF increase at elevated temperatures.
Can the SS215FSH be used in synchronous rectification circuits?
No, the SS215FSH is a passive Schottky rectifier and cannot replace a MOSFET in synchronous rectification. It functions as a unidirectional freewheeling or output rectifier only. For synchronous designs, an external gate driver and low-RDS(on) MOSFET are required. However, the SS215FSH remains ideal for asynchronous topologies where simplicity, cost, and reliability outweigh marginal efficiency gains from synchronization.
