Product details
Overview
SR220 A0G from Taiwan Semiconductor is a 2 A, 200 V Schottky barrier rectifier in DO-204AC (DO-15) package, featuring VF = 0.95 V at 2 A and TJ = 25°C, IR ≤ 100 µA at 25°C, IFSM = 50 A, and RθJL = 21.7 °C/W. It serves as a high-efficiency output rectifier in low-voltage DC/DC converters.
For engineers reviewing the SR220 A0G datasheet, SR220 A0G pinout, SR220 A0G application, or SR220 A0G equivalent, key selection criteria include forward voltage drop at rated current, reverse leakage at elevated temperature, surge capability, thermal resistance, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring structure to enhance overvoltage ruggedness. Its low VF and high IFSM support high-efficiency, high-reliability operation in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) topologies.
The device operates across TJ = –55°C to +150°C, with RθJA = 75.0 °C/W and RθJC = 14.0 °C/W, enabling thermal management in compact power supplies. Reverse recovery is inherently negligible due to majority-carrier conduction.

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-2EY200-M3/57T | VRRM = 200 V, IF = 2 A, VF = 0.92 V @ 2 A, but RθJA = 85 °C/W (higher thermal resistance) | Lacks AEC-Q101 qualification; not recommended for automotive under-hood use | Preferred where lower VF is prioritized and thermal headroom exists |
| ON Semiconductor SB220-E3/54 | VRRM = 200 V, IF = 2 A, VF = 0.93 V @ 2 A, IR = 200 µA @ 25°C (higher leakage) | RoHS-compliant but halogen-containing; not compliant with IEC 61249-2-21 | Suitable for cost-sensitive industrial adapters where leakage < 500 µA is acceptable |
Compared with VS-2EY200-M3/57T and SB220-E3/54, the SR220 A0G delivers superior thermal performance (RθJL = 21.7 °C/W), tighter leakage control (≤100 µA), and halogen-free compliance-making it optimal for space-constrained, thermally demanding, and environmentally regulated designs.

FAQ
What is the maximum junction temperature rating for SR220 A0G?
The SR220 A0G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in TSC's official datasheet Version L2105. This rating applies across the full operating voltage range and enables reliable use in sealed enclosures or high-ambient environments where passive cooling dominates. The SR220 A0G must be derated above 75°C ambient per its forward current derating curve.
Is SR220 A0G AEC-Q101 qualified?
No, the SR220 A0G is not AEC-Q101 qualified. Only the SR220H and SR220HA0G variants carry AEC-Q101 certification per ordering information in the datasheet. The "A0G" suffix denotes ammo box packaging (1,500 units) and green compound, not automotive qualification. For automotive under-hood applications, specify SR220H or SR220HA0G instead of SR220 A0G.
What is the forward voltage drop of SR220 A0G at 2 A and 125°C?
The datasheet does not specify VF at 125°C for SR220 A0G; only VF = 0.95 V (max) is given at 25°C. However, typical VF increases ~1.8 mV/°C for Schottky diodes, so VF at 125°C is estimated near 1.13 V. For design-critical thermal analysis, engineers should consult TSC's Fig.4 Typical Forward Characteristics curve or perform bench validation, as SR220 A0G's actual VF at 125°C depends on test conditions and unit-to-unit variation.
Does SR220 A0G have a guard ring structure?
Yes, the SR220 A0G incorporates a guard ring structure explicitly stated in the FEATURES section of the official datasheet. This design enhances overvoltage protection by controlling electric field distribution at the die edge, improving dv/dt immunity to 10,000 V/µs and increasing ruggedness against transient voltage spikes in switching power supplies.
What is the reverse leakage current of SR220 A0G at 200 V and 125°C?
Per the ELECTRICAL SPECIFICATIONS table, SR220 A0G exhibits IR ≤ 2 mA at VR = 200 V and TJ = 125°C. This value is confirmed for the SR215 and SR220 variants in the "TJ = 125°C" row under reverse current testing conditions. At 100°C, IR is ≤ 2 mA for SR209–SR220; at 125°C, only SR209–SR220 are specified, with SR220 A0G falling within that group.
