Taiwan Semiconductor Corporation SR210

Overview

SR210 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 100 µA reverse leakage at 25°C, used in high-efficiency DC/DC converters and industrial power adapters.

For engineers reviewing the SR210 datasheet, SR210 pinout, SR210 application, or SR210 equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 50 A surge current rating, AEC-Q101 qualification option (SR210H), thermal resistance of 21.7 °C/W (junction-to-lead), and low-power-loss operation in compact SMPS designs.

Technical Context

This discrete Schottky diode 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, and 125–150 °C maximum junction temperature support stable operation in thermally constrained power stages.

The device delivers low conduction loss via 0.85 V forward voltage at rated current and maintains tight reverse leakage (≤100 µA at 25°C, ≤2 mA at 125°C), enabling high-efficiency switching topologies where diode recovery and thermal management are critical.

FAQ

What is the maximum junction temperature rating for SR210?

The SR210 has a maximum junction temperature (T_J) of +150°C under specified operating conditions. This rating applies when used within absolute maximum ratings and with adequate thermal management-such as sufficient copper area on the PCB leads-to maintain junction temperature below this limit during continuous 2 A conduction. The SR210 datasheet specifies both 125°C and 150°C variants; the SR210 part itself is rated to 150°C.

Is SR210 available in an AEC-Q101 qualified version?

Yes, the AEC-Q101 qualified version of SR210 is designated SR210H and shares identical electrical and thermal specifications with the standard SR210, including 100 V V_RRM, 0.85 V V_F, and 50 A I_FSM. The SR210H undergoes additional stress testing per AEC-Q101 standards and is marked with an "H" suffix in the ordering code.

What is the reverse leakage current of SR210 at elevated temperature?

The SR210 exhibits ≤2 mA reverse leakage current (I_R) at rated 100 V reverse voltage and 125°C junction temperature. At 25°C and 100 V, leakage is ≤100 µA. This behavior is confirmed in the Electrical Specifications table and supports reliable operation in high-ambient-temperature environments such as enclosed power supplies.

Does SR210 have a guard ring structure, and what benefit does it provide?

Yes, the SR210 incorporates a guard ring structure explicitly noted in its FEATURES section. This design enhances edge termination robustness, improving resistance to surface flashover and localized avalanche during voltage transients-critical for maintaining reliability in unregulated input or load-dump scenarios without requiring external snubbers.

What packaging options are offered for SR210?

The SR210 is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (ordering code SR210) and 1,500 units per ammo box (ordering code SR210A0G). AEC-Q101 qualified versions follow the same packaging scheme with "H" suffix (e.g., SR210H, SR210HA0G).
