Product details
Overview
SR215 A0G from Taiwan Semiconductor is a 2 A, 150 V Schottky barrier rectifier in DO-204AC (DO-15) package, featuring 0.95 V forward voltage at 2 A and 25°C, 100 µA reverse leakage at 25°C, 50 A surge current capability, and AEC-Q101 qualification option (H-suffix). It serves as a high-efficiency output rectifier in DC/DC converters for automotive infotainment power supplies.
For engineers reviewing the SR215 A0G datasheet, SR215 A0G pinout, SR215 A0G application, or SR215 A0G equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, low VF for thermal management in compact adapters, junction-to-lead thermal resistance of 21.7°C/W, and cathode-band polarity marking for reliable PCB assembly.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its 10,000 V/µs critical dv/dt rating supports fast-switching topologies without parasitic turn-on.
Rated for operation from –55°C to +150°C junction temperature, it delivers stable reverse leakage ≤2 mA at 125°C and maintains 2 A average forward current under natural convection per derating curve - enabling use in thermally constrained industrial SMPS designs.

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-M3/54 | Same DO-15 package, 2 A/150 V, VF = 0.89 V @ 2 A, IR = 200 µA @ 25°C | Higher leakage may increase standby loss in battery-backed systems | Prefer when lowest VF is prioritized and leakage <200 µA is acceptable |
| ON Semiconductor SB2150 | DO-15, 2 A/150 V, VF = 0.92 V @ 2 A, IR = 150 µA @ 25°C, no AEC-Q101 option | Lacks automotive qualification path; different thermal resistance (RθJL = 25°C/W) | Select for cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with VS-2EY15-M3/54 and SB2150, SR215 A0G offers tighter IR control (100 µA) and documented AEC-Q101 availability - making it preferable for automotive modules requiring validated reliability, while maintaining identical footprint and mounting compatibility.

FAQ
What is the maximum junction temperature rating for SR215 A0G?
The SR215 A0G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet Version L2105. This allows sustained operation in high-ambient environments such as under-hood automotive modules or enclosed industrial power supplies where airflow is limited. The SR215 A0G must be derated linearly above 25°C ambient per the forward current derating curve shown in Figure 1.
Is SR215 A0G pin-compatible with other parts in the SR202–SR220 family?
Yes, all SR202–SR220 devices, including SR215 A0G, share identical DO-204AC (DO-15) package dimensions, axial lead configuration, and cathode-band polarity marking. This ensures mechanical and layout compatibility across the family - allowing voltage-scaling substitutions (e.g., SR210 → SR215) without PCB revision, provided thermal and electrical margins are re-verified for the new VRRM and VF.
Does SR215 A0G meet automotive qualification standards?
The base SR215 A0G is not AEC-Q101 qualified; however, the SR215HA0G variant (with "H" suffix) is explicitly qualified per AEC-Q101. Per TSC's ordering information table, "H" denotes AEC-Q101 qualification. Engineers requiring automotive-grade reliability must specify SR215HA0G - the SR215 A0G itself is rated for industrial and commercial applications only.
What is the typical forward voltage of SR215 A0G at 2 A and 100°C junction temperature?
The datasheet specifies VF only at TJ = 25°C (0.95 V max). While no typ/max value is given at 100°C, Figure 4 (Typical Forward Characteristics) shows VF increases ~0.1 V between 25°C and 125°C for SR215–SR220. Thus, SR215 A0G VF at 2 A and 100°C is approximately 1.02–1.05 V - a critical input for thermal simulation and efficiency calculation in high-temperature operation.
How is polarity indicated on the SR215 A0G package?
Polarity on the SR215 A0G is indicated by a visible cathode band - a painted or molded stripe near one lead end. Per mechanical data section, this band identifies the cathode terminal (lead 2), which must connect to the higher-potential node in forward conduction. The unmarked lead is the anode (lead 1). This marking complies with JEDEC DO-204AC standard and is verified in the Marking Diagram on page 6 of the TSC datasheet.
