Product details

Overview

SR206 from Taiwan Semiconductor is a 2 A, 60 V Schottky barrier rectifier in DO-204AC (DO-15) package, featuring 0.70 V forward voltage at 2 A and 25°C, 50 A surge current capability, and AEC-Q101 qualification option. It delivers low power loss in compact SMPS and DC-DC converter designs.

For engineers reviewing the SR206 datasheet, SR206 pinout, SR206 application, or SR206 equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 5 mA reverse leakage at 100°C, junction-to-lead thermal resistance of 21.7°C/W, and compatibility with lead-free reflow soldering per J-STD-002.

Technical Context

This Schottky rectifier uses a single-die construction with guard ring for overvoltage protection and operates across a -55°C to +150°C junction temperature range. Its 10,000 V/µs critical rate of rise of off-state voltage supports fast-switching topologies.

The device exhibits 75.0°C/W junction-to-ambient thermal resistance and achieves high efficiency via low forward voltage drop - 0.70 V typical at 2 A and 25°C - while maintaining 500 µA max reverse current at rated 60 V and 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - maximum repetitive reverse blocking voltage without breakdown
I_F	2 A - continuous average forward current rating at case temperature ≤ 75°C
I_FSM	50 A - non-repetitive surge current handling for 8.3 ms half-sine wave
V_F @ 2 A, 25°C	0.70 V - low conduction loss enabling high-efficiency power conversion
I_R @ 60 V, 25°C	500 µA - minimal leakage ensuring stable reverse-biased operation
T_J Range	-55°C to +150°C - extended thermal operating envelope for under-hood or industrial environments
R_θJL	21.7°C/W - thermal path efficiency from junction to lead, critical for PCB heat sinking

Pinout & Package

Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band polarity marking and pure tin-plated leads compliant with J-STD-002 solderability.

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-2EY60-M3/57T	Same DO-204AC package, 2 A/60 V, VF = 0.72 V @ 2 A, IR = 400 µA @ 25°C	Slightly higher VF increases conduction loss; identical thermal specs and surge rating	Preferred where Vishay supply chain alignment or dual-sourcing is required
ON Semiconductor SB260-E3/54	DO-204AC, 2 A/60 V, VF = 0.75 V @ 2 A, IR = 500 µA @ 25°C, TJ max = 125°C (not 150°C)	Lower max junction temperature limits high-ambient deployments; otherwise functionally aligned	Valid alternative where 125°C operation suffices and ON Semi BOM consolidation is strategic

Compared with SR206, VS-2EY60-M3/57T offers near-identical electrical performance with minor VF trade-off, while SB260-E3/54 sacrifices 25°C thermal headroom but maintains matching voltage/current ratings for less demanding thermal environments.

FAQ

What is the maximum junction temperature rating for SR206?

The SR206 has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the L2105 datasheet revision. This allows reliable operation in high-ambient environments such as enclosed automotive ECUs or sealed industrial power modules when thermal design accounts for its 21.7°C/W junction-to-lead resistance. The SR206 must not exceed this limit under steady-state or transient conditions.

Is SR206 pin-compatible with other parts in the SR202–SR220 family?

Yes, all parts in the SR202–SR220 family-including SR206-share identical DO-204AC (DO-15) package dimensions, anode/cathode lead configuration, and polarity marking. Mechanical interchangeability is guaranteed; however, electrical parameters (V_RRM, V_F, I_R) differ across the series, so substitution requires verification against circuit voltage and loss requirements.

Does SR206 meet automotive qualification standards?

The base SR206 is not AEC-Q101 qualified, but the SR206H variant-marked with "H" suffix-is explicitly qualified per AEC-Q101. Per TSC ordering information, SR206H meets stress test requirements for temperature cycling, humidity, and mechanical shock, making it suitable for automotive power conversion where qualification evidence is contractually required.

What is the reverse leakage current of SR206 at elevated temperature?

At 100°C junction temperature and rated 60 V reverse voltage, the SR206 exhibits a maximum reverse leakage current (I_R) of 5 mA, as specified in the electrical characteristics table. This value is confirmed under pulse test conditions (PW = 30 ms) and reflects realistic worst-case behavior in thermally stressed applications like engine bay power modules.

Can SR206 be used in surface-mount designs?

No, SR206 is packaged exclusively in the through-hole DO-204AC (DO-15) axial-leaded format and is not available in surface-mount variants. Its lead geometry and mechanical data specify axial mounting with lead forming per JEDEC standards. For SMT implementation, engineers must select alternate Schottky families such as TSC's SMB/SMA packages or equivalent SOD-123/SMAJ footprints.
