Taiwan Semiconductor Corporation SSH210

Overview

SSH210 from Taiwan Semiconductor is a 2A, 100V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, featuring VF ≤ 0.79 V at 2A/25°C, IFSM = 75 A, TJ max = 175°C, and RθJA = 62°C/W - optimized for high-efficiency DC output stages in compact AC/DC adapters and SMPS.

For engineers reviewing the SSH210 datasheet, SSH210 pinout, SSH210 application, or SSH210 equivalent, key selection criteria include forward voltage drop at operating temperature, surge current capability under 8.3ms half-sine stress, thermal resistance on standard PCB pads, cathode-band polarity marking, and RoHS/halogen-free compliance for consumer electronics manufacturing.

Technical Context

The SSH210 employs a single-die Schottky junction structure with guard ring overvoltage protection, enabling low conduction loss and fast switching without reverse recovery charge. Its DO-214AA (SMB) package supports automated placement and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity.

Thermal performance is characterized with RθJL = 14°C/W and RθJC = 18°C/W on a 10mm × 10mm Cu pad test board. Electrical behavior is specified across -55°C to +175°C junction range, with IR ≤ 1 µA at 25°C and ≤ 1 mA at 125°C under rated VR.

FAQ

What is the maximum junction temperature rating for the SSH210?

The SSH210 has a maximum junction temperature (TJ max) of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in thermally demanding environments such as enclosed adapters and TV power boards. Derating curves confirm usable current capacity down to 1.2 A at 125°C ambient on standard PCB layouts. The SSH210 must be operated within this limit to ensure long-term reliability and avoid parametric shift.

Does the SSH210 have a guarded junction, and what does that provide?

Yes, the SSH210 incorporates a guard ring structure explicitly stated in its features list. This design enhances edge termination robustness, improving resistance to transient overvoltage events without requiring external clamping components. It directly contributes to the device's ability to sustain rated VRRM under real-world line transients and improves long-term reliability in switching power supplies. The guard ring is integral to the SSH210 die layout and validated in TSC's qualification testing.

What is the forward voltage drop of the SSH210 at elevated temperature?

The SSH210 exhibits VF = 0.65 V at IF = 2 A and TJ = 125°C, per electrical specifications in the Taiwan Semiconductor datasheet. This lower VF at high temperature - compared to 0.79 V at 25°C - reflects the negative temperature coefficient typical of Schottky diodes and reduces conduction loss under thermal stress. Designers should use the 125°C value for worst-case thermal analysis in enclosed or high-ambient applications.

Is the SSH210 suitable for lead-free reflow soldering processes?

Yes, the SSH210 is qualified for lead-free reflow soldering per J-STD-002. Its matte tin-plated leads are fully solderable using standard Pb-free profiles (peak temperature up to 260°C). With J-STD-020 Moisture Sensitivity Level 1, the SSH210 can be placed directly from dry pack without baking - eliminating process steps and reducing risk of popcorning during reflow. This makes the SSH210 ideal for high-throughput SMT lines.

How does the SSH210's thermal resistance compare on standard PCB mounting?

When mounted on a 10 mm × 10 mm copper pad per JEDEC test conditions, the SSH210 achieves RθJA = 62°C/W and RθJL = 14°C/W. These values are measured and published in the thermal performance section of the datasheet. Designers should use RθJA = 62°C/W for initial thermal budgeting; actual board-level performance may improve with additional copper pour or thermal vias. The low RθJL confirms efficient heat transfer to the PCB land pattern.
