Product details

Overview

TSD3JFS from Taiwan Semiconductor is a 600V, 3A glass-passivated ESD-hardened rectifier diode in SOD-128 package, with 50A surge rating, 0.96V forward voltage at 3A/25°C, and ≥10kV IEC 61000-4-2 contact-mode ESD immunity-used for polarity protection in industrial power supplies and DC input stages.

For engineers reviewing the TSD3JFS datasheet, TSD3JFS pinout, TSD3JFS application, or TSD3JFS equivalent, key selection criteria include its 600V VRRM, 175°C junction temperature rating, SOD-128 thermal performance (RθJL = 15°C/W), and verified AEC-Q101 Class H3B human-body ESD robustness.

Technical Context

This device is a single-die, surface-mount silicon rectifier optimized for high-reliability DC input protection where transient overvoltage and electrostatic discharge are critical concerns. Its glass-passivated junction ensures stable leakage current (<1µA at 25°C) and low capacitance (18pF at 4V), while the SOD-128 package enables automated placement and meets JESD201 Class 2 whisker resistance.

The TSD3JFS operates across –40°C to +175°C ambient, with thermal derating defined by RθJA = 70°C/W on a 5mm × 5mm Cu pad. Its 1.1V max forward voltage at 3A/25°C and 0.85V typical at 3A/125°C support efficient conduction in thermally constrained designs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
STTH3L06S600V VRRM, 3A IF, but VF = 1.3V @ 3A - 36% higher conduction loss; TO-277 package (larger footprint, higher RθJA).Higher thermal resistance (RθJA ≈ 90°C/W) requires larger copper area or forced cooling in same layout.Choose when legacy TO-277 footprint compatibility is required and higher VF is acceptable.
MBR360FCT60V VRRM, 3A IF, Schottky architecture - lower VF (0.52V), but unsuitable for >100V reverse stress.Cannot replace TSD3JFS in 400–600V applications due to catastrophic reverse breakdown below rated voltage.Only viable in low-voltage DC systems where reverse voltage never exceeds 60V.

Compared with STTH3L06S and MBR360FCT, the TSD3JFS uniquely balances 600V capability, low VF, SOD-128 space efficiency, and certified ESD robustness-making it optimal for compact, high-reliability DC input protection where voltage, thermal, and ESD margins are simultaneously constrained.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) for TSD3JFS?

The TSD3JFS has a VRRM of 600 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2309). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is strictly validated for the TSD3JFS variant-not extrapolated from TSD3GFS or other family members.

Does TSD3JFS meet AEC-Q101 qualification?

Yes, the TSD3JFS is rated Class H3B per AEC-Q101-001 Human Body Model (HBM), with ≥8 kV ESD immunity. This qualification is explicitly stated in the "Immunity to Electrical Static Discharge" section of the datasheet and applies to the TSD3JFS part number as shipped, not inferred from family-level testing.

What is the forward voltage (VF) of TSD3JFS at 3A and 125°C?

At 3.0 A forward current and 125°C junction temperature, the TSD3JFS exhibits a typical forward voltage of 0.85 V, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects reduced conduction loss at elevated temperatures compared to room-temperature operation.

Is TSD3JFS compatible with lead-free reflow soldering processes?

Yes, the TSD3JFS uses matte tin-plated leads compliant with J-STD-002 and is rated for lead-free reflow soldering. Its moisture sensitivity level is J-STD-020 Level 1, meaning it can be stored indefinitely at ≤30°C/85% RH without baking prior to assembly-confirmed in the Mechanical Data section of the datasheet.

What is the thermal resistance from junction to ambient (RθJA) for TSD3JFS?

The TSD3JFS has an RθJA of 70°C/W when mounted on a standard 5 mm × 5 mm copper pad test board, as documented in the Thermal Performance table. This value assumes natural convection and is used for initial thermal design; actual performance depends on PCB copper area, layer count, and airflow.
