Taiwan Semiconductor Corporation TSD2JFS

Overview

TSD2JFS from Taiwan Semiconductor is a 2 A, 600 V glass-passivated ESD-hardened surface-mount rectifier in SOD-128 package, featuring 40 A surge current rating, 15 °C/W junction-to-lead thermal resistance, and ≥10 kV IEC 61000-4-2 contact-mode ESD immunity-used for polarity protection in industrial power supplies and DC input stages.

For engineers reviewing the TSD2JFS datasheet, TSD2JFS pinout, TSD2JFS application, or TSD2JFS equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, low 0.94 V forward voltage at 2 A/25°C, 175°C max junction temperature, SOD-128 mechanical compatibility, and AEC-Q101-001 H3B-class ESD robustness.

Technical Context

The TSD2JFS is a single-die, standard recovery silicon rectifier optimized for high-reliability DC input protection. Its glass-passivated junction ensures stable leakage performance up to 125°C (IR ≤ 5 µA), while the SOD-128 package enables high-power density mounting on 5 mm × 5 mm copper pads with R_θJA = 75 °C/W.

It delivers 2 A average forward current with derating above 75°C ambient, supports 40 A non-repetitive surge (8.3 ms sine), and exhibits 15 pF junction capacitance at 4 V reverse bias-making it suitable for moderate-frequency (<1 MHz) rectification where ESD resilience and thermal stability are critical.

FAQ

What is the maximum repetitive peak reverse voltage rating for the TSD2JFS?

The TSD2JFS has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2309). This rating defines the highest continuous reverse voltage the device can block without breakdown under normal operating conditions. Exceeding this value risks irreversible junction failure. The TSD2JFS is therefore suited for applications such as 400–500 V DC input stages where a 100 V safety margin is required.

Does the TSD2JFS meet AEC-Q101 reliability standards?

Yes, the TSD2JFS meets AEC-Q101-001 Human Body Model (HBM) Class H3B (≥8 kV), as explicitly stated in the Immunity to Electrical Static Discharge section of the datasheet. This qualification confirms its suitability for automotive-grade applications requiring robustness against electrostatic discharge during handling and operation. The TSD2JFS is not just tested to AEC-Q101-it is formally rated and marked per that standard, distinguishing it from non-qualified rectifiers.

What is the forward voltage drop of the TSD2JFS at 2 A and 25°C?

The forward voltage drop (V_F) of the TSD2JFS is 0.94 V maximum at 2 A forward current and 25°C junction temperature, per the Electrical Specifications table. At typical operating conditions (2 A, 25°C), V_F is 0.94 V-this value directly determines conduction loss (P_cond = I_F × V_F ≈ 1.88 W) and must be included in thermal design calculations for PCB copper area and ambient temperature derating.

Is the TSD2JFS compatible with lead-free reflow soldering processes?

Yes, the TSD2JFS features matte tin-plated leads compliant with J-STD-002 for solderability, and its SOD-128 package is rated for lead-free reflow profiles per JEDEC J-STD-020 (Moisture Sensitivity Level 1). The device requires no pre-baking and withstands peak temperatures up to 260°C, making it fully compatible with standard Pb-free assembly lines used in industrial and automotive electronics manufacturing.

What is the junction-to-lead thermal resistance (R_θJL) of the TSD2JFS?

The junction-to-lead thermal resistance (R_θJL) of the TSD2JFS is 15 °C/W, as specified in the Thermal Performance table. This parameter is measured with the device mounted on a 5 mm × 5 mm copper pad test board and reflects heat transfer efficiency from die to solder joint. It enables accurate thermal modeling for applications where the device is soldered directly to large copper areas without additional heatsinking-critical for compact industrial power designs.
