Product details
Overview
SR106 A0G from Taiwan Semiconductor is a 1A, 60V Schottky barrier rectifier in DO-204AL (DO-41) package, featuring 0.70V typical forward voltage at 1A/25°C, 30A surge capability, and 500µA max reverse leakage at 25°C. It serves as a primary output rectifier in compact DC-DC converters and AC adapters.
For engineers reviewing the SR106 A0G datasheet, SR106 A0G pinout, SR106 A0G application, or SR106 A0G equivalent, key selection criteria include its 60V VRRM, thermal resistance of 90°C/W, AEC-Q101 qualification option (via H-suffix), RoHS/halogen-free compliance, and DO-41 mechanical compatibility with standard through-hole layouts.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring for overvoltage protection and pure tin-plated leads compliant with J-STD-002 solderability. Its junction temperature range spans –55°C to +125°C (standard grade) or +150°C (high-temp variant), supporting operation in thermally constrained power stages.
The device delivers high efficiency via low forward voltage drop and low power loss, enabled by optimized metal-semiconductor interface design. Critical dv/dt rating of 10,000 V/µs ensures robustness against fast transient switching noise in SMPS flyback and buck topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC-DC output stage |
| IF | 1 A - Continuous average forward current; sets baseline conduction capacity at TA = 25°C |
| IFSM | 30 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling |
| VF @ 1A, 25°C | 0.70 V typ - Low conduction loss directly reduces heat generation and improves system efficiency |
| IR @ 60V, 25°C | 500 µA max - Low leakage preserves standby power integrity in energy-sensitive applications |
| RθJA | 90 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements in sealed enclosures |
| TJ max | 125 °C - Maximum junction temperature for standard-grade operation; constrains PCB copper area and airflow needs |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded case meeting UL 94V-0 flammability rating. Cathode indicated by band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead without band) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck, secondary winding in flyback) |
| Cathode (lead with band) | Forward current exit / reverse blocking terminal | Connected to output rail; blocks reverse voltage during off-state; polarity critical for correct rectification |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage events without derating VRRM |
| Pure tin-plated leads | Ensures reliable solder wetting and long-term intermetallic stability per J-STD-002 |

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-1EQH06-M3/5BT | Same DO-41 package, 60V VRRM, 0.69V VF @ 1A, but rated for 150°C TJ max and AEC-Q101 qualified as standard | Preferred for automotive infotainment power supplies requiring extended temperature validation | Select when AEC-Q101 compliance is mandatory and higher junction temperature margin is required |
| ON Semiconductor SB160-E3/54 | DO-41, 60V VRRM, 0.72V VF @ 1A, 25A IFSM, RoHS-compliant but not halogen-free | Suitable for cost-sensitive industrial adapters where halogen-free certification is not mandated | Choose for legacy designs aligned with ON Semi's SBx60 family and where 5A lower surge rating is acceptable |
Compared with SR106 A0G, VS-1EQH06-M3/5BT offers guaranteed AEC-Q101 qualification and +150°C operation but at higher unit cost; SB160-E3/54 provides functional equivalence with reduced surge margin and no halogen-free assurance, making it viable only in non-automotive, non-green-certified programs.

FAQ
What is the maximum junction temperature rating for SR106 A0G?
The SR106 A0G has a maximum junction temperature (TJ) of +125°C under standard operating conditions. This rating is confirmed in the Absolute Maximum Ratings table of the G2104 datasheet revision and applies to the base SR106 A0G variant-not the high-temperature SR106H version, which extends to +150°C. Thermal design must ensure junction temperature remains below this limit during continuous 1A operation.
Is SR106 A0G AEC-Q101 qualified?
No, SR106 A0G is not AEC-Q101 qualified. The "H" suffix (e.g., SR106H or SR106HA0G) denotes AEC-Q101 qualification per the Ordering Information table. SR106 A0G uses the same DO-41 package and electrical specs but lacks the automotive-grade stress testing and traceability documentation required for AEC-Q101 compliance.
What does the "A0G" suffix mean in SR106 A0G?
The "A0G" suffix in SR106 A0G indicates packaging: "A0" specifies ammo box packaging (3,000 units per box), and "G" denotes green (halogen-free) molding compound per IEC 61249-2-21. This differs from tape-and-reel ("SR106") or AEC-Q101-compliant ("H") variants, and confirms RoHS and halogen-free compliance without implying automotive qualification.
What is the forward voltage of SR106 A0G at 1A and 100°C junction temperature?
The SR106 A0G exhibits a typical forward voltage of approximately 0.62V at 1A and 100°C, derived from the Typical Forward Characteristics curve (Fig.4) in the G2104 datasheet. While the datasheet tabulates VF only at 25°C (0.70V typ), the curve shows monotonic decrease with rising temperature-a characteristic of Schottky diodes-and confirms sub-0.65V operation at 100°C.
Can SR106 A0G replace SR106H in an automotive design?
No, SR106 A0G cannot replace SR106H in automotive designs requiring AEC-Q101 qualification. Although both share identical electrical parameters and DO-41 packaging, SR106H undergoes additional qualification testing (HTOL, TC, UHAST, etc.) and includes full traceability documentation. Using SR106 A0G in such applications violates automotive reliability requirements and voids system-level certification.
