Product details

Overview

SR215 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 for automotive-grade reliability in DC–DC converters.

For engineers reviewing the SR215 datasheet, SR215 pinout, SR215 application, or SR215 equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, thermal resistance (R_θJL = 21.7°C/W), junction temperature range (–55°C to +150°C), and DO-15 mechanical compatibility with standard through-hole power rectifier footprints.

Technical Context

The SR215 operates as a single-die, unidirectional Schottky rectifier optimized for high-frequency switching applications. Its low forward voltage drop reduces conduction loss, while the guard ring structure enhances transient overvoltage robustness without external snubbers.

Thermally, it delivers R_θJL = 21.7°C/W and R_θJA = 75.0°C/W under standard mounting conditions, supporting continuous 2 A operation up to 125°C ambient when adequately heatsinked via lead termination.

Key Specifications

V_RRM	150 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or boost diode positions
I_F	2 A - Continuous average forward current; sets minimum trace width and PCB copper area requirements
V_F	0.95 V @ 2 A, 25°C - Directly determines conduction loss (1.9 W at full load), critical for thermal budgeting
I_R	100 µA @ 150 V, 25°C - Low leakage enables stable hold-up in standby modes of AC–DC adapters
I_FSM	50 A - Peak non-repetitive surge rating; supports inrush current handling in SMPS input stages
T_J max	+150°C - Enables operation in under-hood automotive environments without derating below 125°C ambient
R_θJL	21.7°C/W - Quantifies thermal path efficiency from junction to lead; informs solder joint thermal design

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-M3/57T	Same DO-204AC package, 2 A/150 V, V_F = 0.89 V @ 2 A, but not AEC-Q101 qualified	Suitable for industrial/commercial SMPS where automotive qualification is not required	Preferred where lower V_F outweighs qualification needs; verify thermal performance with R_θJL = 25°C/W
ON Semiconductor SB2150-E3/54	DO-204AC, 2 A/150 V, V_F = 0.92 V @ 2 A, AEC-Q101 qualified, but I_R = 200 µA @ 25°C	Better surge robustness (I_FSM = 60 A), higher leakage limits use in low-power standby circuits	Select when higher surge margin is critical; accept trade-off in light-load efficiency due to doubled I_R

Compared with VS-2EY15-M3/57T and SB2150-E3/54, the SR215 offers balanced V_F/I_R performance and guaranteed AEC-Q101 compliance in a cost-optimized DO-15 platform, making it optimal for automotive and industrial DC–DC where qualification and thermal predictability are jointly prioritized.

FAQ

What is the maximum junction temperature rating for the SR215?

The SR215 has a maximum junction temperature (T_J) rating of +150°C, validated per AEC-Q101 stress testing. This allows operation in under-hood automotive environments up to 125°C ambient when mounted on standard FR-4 PCB with 1 oz copper, provided thermal design accounts for R_θJL = 21.7°C/W. The SR215 datasheet specifies derating curves starting at 25°C ambient.

Does the SR215 have AEC-Q101 qualification?

Yes, the SR215 is AEC-Q101 qualified - confirmed in the official Taiwan Semiconductor datasheet revision L2105, Section "FEATURES". This qualification covers temperature cycling, highly accelerated life testing (HALT), and ESD robustness, making the SR215 suitable for automotive powertrain and body control modules where reliability is mission-critical.

What is the forward voltage of the SR215 at 2 A and 125°C junction temperature?

The SR215 datasheet specifies V_F = 0.95 V only at T_J = 25°C. At elevated temperatures, V_F decreases - typical curves (Fig.4) show ~0.82 V at 125°C and 2 A. This negative temperature coefficient improves thermal stability in high-ambient applications, reducing risk of thermal runaway compared to silicon PN diodes.

Can the SR215 replace the SR210 in an existing design?

Yes, the SR215 can replace the SR210 in most cases because both share identical DO-204AC packaging, pinout, and thermal characteristics. However, the SR215 has higher V_RRM (150 V vs. 100 V) and slightly higher V_F (0.95 V vs. 0.85 V), so verify that reverse voltage margin is sufficient and conduction loss remains within thermal budget. No PCB changes are needed.

What is the reverse leakage current of the SR215 at 150 V and 100°C?

The SR215 exhibits ≤2 mA reverse leakage current (I_R) at 150 V and T_J = 100°C, per the "ELECTRICAL SPECIFICATIONS" table in the L2105 datasheet. This value is measured under pulse conditions (PW = 30 ms) and reflects worst-case behavior in high-temperature operation, such as inside sealed LED drivers or automotive engine compartments.
