Taiwan Semiconductor Corporation SR210 A0G

Overview

SR210 A0G from Taiwan Semiconductor is a 2 A, 100 V Schottky barrier rectifier in DO-204AC (DO-15) package, featuring 0.85 V forward voltage at 2 A and 25°C, 100 µA reverse leakage at rated VR and 25°C, 50 A surge current capability, and AEC-Q101 qualification option (H-suffix variants). It serves as a primary output rectifier in compact DC/DC converters.

For engineers reviewing the SR210 A0G datasheet, SR210 A0G pinout, SR210 A0G application, or SR210 A0G equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, low VF for thermal efficiency, DO-15 mechanical compatibility, and junction temperature range up to +150°C in automotive-grade configurations.

Technical Context

This device operates as a unidirectional power rectifier with single-die construction and guard-ring overvoltage protection. Its 100 V V_RRM, 2 A continuous forward current rating, and 50 A non-repetitive surge capability support high-efficiency switching topologies where conduction loss minimization is critical.

The SR210 A0G exhibits a typical junction-to-lead thermal resistance of 21.7°C/W and junction-to-ambient of 75.0°C/W, enabling reliable operation under sustained load in constrained PCB layouts. Reverse leakage remains ≤100 µA at 25°C and ≤2 mA at 125°C, supporting stable performance across industrial temperature ranges.

FAQ

What is the maximum junction temperature rating for SR210 A0G?

The SR210 A0G has a maximum junction temperature of +150°C, validated per the absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version L2105). This rating applies to all SR2x variants marked "SR210" and enables operation in high-ambient environments such as engine compartments or enclosed industrial enclosures without forced cooling. The SR210 A0G maintains specified electrical parameters up to this limit when thermal design adheres to R_θJL = 21.7°C/W.

Is SR210 A0G pin-compatible with other DO-15 Schottky rectifiers?

Yes, the SR210 A0G uses the standard DO-204AC (DO-15) axial package with anode and cathode leads spaced 5.0–5.5 mm apart, matching industry-standard DO-15 footprints. Its polarity marking (cathode band) aligns with JEDEC MO-127, ensuring drop-in replacement for any DO-15 Schottky rectifier with identical voltage/current ratings. Mechanical compatibility is confirmed in the Package Outline Dimensions section (Page 6) of the SR202–SR220 datasheet.

Does SR210 A0G meet AEC-Q101 reliability standards?

The SR210 A0G itself is not AEC-Q101 qualified; however, the SR210H and SR210HA0G variants are explicitly listed as AEC-Q101 qualified in the Ordering Information table (Page 3). The "H" suffix denotes full qualification per AEC-Q101 stress tests including HTGB, HTRB, and temperature cycling. For automotive applications requiring AEC-Q101, specify SR210H or SR210HA0G-not SR210 A0G.

What is the forward voltage specification for SR210 A0G at elevated temperature?

The SR210 A0G forward voltage increases with junction temperature: typical V_F is 0.85 V at 25°C, rising to approximately 0.72 V at 125°C (per Fig.4 Typical Forward Characteristics, Page 4). This negative temperature coefficient improves current sharing in parallel configurations and reduces thermal runaway risk. The value is measured at I_F = 2 A with 0.3 ms pulse width, as defined in the Electrical Specifications table.

How does the guard ring feature improve reliability in SR210 A0G?

The guard ring in the SR210 A0G enhances edge termination robustness, preventing localized electric field crowding during high dv/dt transients. As stated in the Features list, it provides overvoltage protection by sustaining 10,000 V/µs critical rate of rise without avalanche initiation. This directly extends operational life in fast-switching SMPS and automotive load-dump scenarios where voltage spikes exceed nominal V_RRM limits.
