Product details
Overview
SS215 from Taiwan Semiconductor is a 2 A, 150 V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, featuring 0.95 V forward voltage at 2 A and 25°C, 5 mA reverse current at 150 V and 125°C, and 50 A surge capability - optimized for high-efficiency switching mode power supplies and lighting converters.
For engineers reviewing the SS215 datasheet, SS215 pinout, SS215 application, or SS215 equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, thermal resistance of 24°C/W (junction-to-lead), RoHS-compliant halogen-free construction, and JESD201 Class 2 whisker-tested matte tin leads.
Technical Context
The SS215 operates as a single-die Schottky rectifier with guard ring over-voltage protection and polarity indicated by cathode band. Its junction temperature range extends to +150°C, supported by 70°C/W junction-to-ambient thermal resistance and 24°C/W junction-to-lead resistance.
Designed for automated placement, it meets moisture sensitivity level 1 per J-STD-020 and UL 94V-0 flammability rating. The device sustains 10,000 V/μs critical rate of rise of off-state voltage and exhibits low forward voltage drift - 0.80 V at 2 A and 100°C - enabling stable performance under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating ceiling in DC-DC and AC-DC output stages |
| IF | 2 A - continuous forward current rating; supports compact SMPS designs without forced cooling |
| VF @ 2A, 25°C | 0.95 V - low conduction loss enabling >92% efficiency in 12–48 V output converters |
| IR @ 150V, 125°C | 5 mA - leakage current threshold limiting standby power loss in high-temp lighting applications |
| IFSM | 50 A - non-repetitive surge rating; withstands inrush during cold-start in adapters and LED drivers |
| RθJL | 24 °C/W - enables direct PCB copper pour heat sinking without external heatsinks in SMB footprint |
| TJ max | +150 °C - extended junction rating allows operation in enclosed, high-ambient industrial 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 SS215HE3/5BT | Same 150 V VRRM, 2 A IF, DO-214AA package; VF = 0.92 V @ 2 A, 25°C; IR = 100 µA @ 25°C | Lower room-temp leakage but higher 125°C IR (10 mA); less thermal margin in sustained high-temp operation | Prefer SS215 for >85°C ambient use; prefer SS215HE3/5BT where ultra-low standby loss dominates |
| ON Semiconductor SS215H | Identical ratings and DO-214AA package; VF = 0.94 V @ 2 A, 25°C; IR = 50 µA @ 25°C; RθJA = 75°C/W | Slightly lower VF but higher thermal resistance; requires larger copper area for same junction temp | Select SS215 when board space limits copper pour; select SS215H if sourcing flexibility across multiple franchises is priority |
Compared with SS215HE3/5BT and SS215H, the SS215 delivers superior high-temperature reverse leakage control (5 mA @ 125°C) and lower junction-to-lead thermal resistance (24°C/W), making it optimal for thermally constrained industrial and lighting applications where long-term reliability outweighs marginal VF differences.

FAQ
What is the maximum junction temperature rating for the SS215?
The SS215 has a maximum junction temperature (TJ max) rating of +150°C, verified per absolute maximum ratings table in the N2306 datasheet. This allows reliable operation in enclosed industrial enclosures or high-ambient LED driver housings where ambient temperatures exceed 85°C. Derating curves confirm usable current capacity down to 1.2 A at 125°C case temperature. The SS215 maintains this rating across its full production lot.
Does the SS215 have a specified forward voltage at elevated temperature?
Yes, the SS215 specifies VF = 0.80 V at 2 A and 100°C junction temperature, per Electrical Specifications Table on page 2 of the N2306 datasheet. This value reflects reduced conduction loss under thermal stress and is critical for predicting efficiency in real-world operating conditions. The SS215's VF temperature coefficient is confirmed stable across -55°C to +150°C.
Is the SS215 suitable for use in RoHS-compliant and halogen-free assemblies?
Yes, the SS215 is explicitly certified RoHS-compliant and halogen-free per manufacturer documentation (N2306 datasheet, page 1). It uses green molding compound meeting UL 94V-0 and complies with IEC 61249-2-21. All plating and substrate materials in the SS215 meet JEDEC J-STD-609A Class 1 requirements for halogen-free status.
What is the reverse leakage current of the SS215 at rated voltage and high temperature?
The SS215 exhibits 5 mA maximum reverse current (IR) at 150 V reverse voltage and +125°C junction temperature, per Electrical Specifications Table (page 3, N2306). This value is measured under 30 ms pulse conditions and defines worst-case standby power loss in high-temp lighting or industrial applications. At 25°C, IR is ≤100 µA.
What package type and lead finish does the SS215 use?
The SS215 uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads, fully compliant with J-STD-002 solderability standards and JESD201 Class 2 whisker testing. The cathode is marked by a visible band, and the device weighs approximately 0.093 g. Package dimensions match JEDEC DO-214AA Issue D specifications.
