Product details

Overview

TSD2GFS from Taiwan Semiconductor is a 2 A, 400 V repetitive peak reverse voltage (V_RRM) glass-passivated ESD-hardened rectifier diode in SOD-128 package, featuring 0.94 V forward voltage at 2 A/25°C, 40 A surge current capability, and AEC-Q101-001 H3B-class ESD immunity (≥8 kV HBM), used for polarity protection in automotive body electronics and industrial power supplies.

For engineers reviewing the TSD2GFS datasheet, TSD2GFS pinout, TSD2GFS application, or TSD2GFS equivalent, key selection criteria include its 400 V V_RRM, 2 A continuous forward current rating, SOD-128 thermal performance (R_θJL = 15 °C/W), ESD robustness per AEC-Q101, and cathode-band polarity marking - all critical for high-reliability DC input stage protection.

Technical Context

This device is a single-die, surface-mount silicon rectifier optimized for automated assembly and high-ESD environments. Its glass-passivated junction ensures stable leakage (<1 µA @ 25°C) and thermal stability up to 175°C junction temperature, while the SOD-128 package provides low R_θJL (15 °C/W) for efficient heat transfer to PCB copper pads.

The TSD2GFS operates with a typical forward voltage of 0.89 V at 1 A/25°C and 0.83 V at 2 A/125°C, enabling low conduction loss across automotive temperature ranges. Reverse recovery behavior is not specified, confirming its use as a general-purpose unidirectional rectifier rather than a fast-switching or soft-recovery diode.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for TSD2GFS?

The TSD2GFS has a maximum repetitive peak reverse voltage (V_RRM) of 400 V, as confirmed in the Absolute Maximum Ratings table of the official datasheet. This rating defines the highest reverse voltage the diode can block continuously without breakdown under normal operating conditions and is strictly specific to the TSD2GFS variant - the TSD2JFS version is rated at 600 V.

Does TSD2GFS meet AEC-Q101 reliability standards?

Yes, the TSD2GFS is qualified to AEC-Q101-001 with Human Body Model (HBM) Class H3B (≥8 kV), as explicitly stated in the Immunity to Electrical Static Discharge section. This qualification applies to the TSD2GFS part number and confirms its suitability for automotive applications requiring certified ESD robustness, unlike generic rectifiers lacking such validation.

What is the forward voltage (V_F) of TSD2GFS at 2 A and 25°C?

The forward voltage of TSD2GFS is 0.94 V maximum at 2 A forward current and 25°C junction temperature, per the Electrical Specifications table. The typical value is 0.94 V, and this parameter is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects - a key specification for calculating conduction losses in the TSD2GFS design-in phase.

Which package does TSD2GFS use, and what are its key mechanical features?

TSD2GFS uses the SOD-128 package, a JEDEC DO-221AD-compliant surface-mount outline with matte tin-plated leads, UL 94V-0 flammability rating, and JESD201 Class 2 whisker resistance. Its dimensions (4.40 × 2.70 × 1.20 mm) and cathode band marking are fully documented in the Package Outline Dimensions section of the TSD2GFS datasheet.

Is TSD2GFS suitable for high-temperature industrial environments?

Yes, TSD2GFS supports operation from −40°C to +175°C junction temperature, with thermal resistance values (R_θJL = 15 °C/W) verified on a 5 mm × 5 mm copper pad test board. This enables reliable use in enclosed industrial enclosures or under-hood automotive locations where ambient temperatures exceed 100°C, provided PCB thermal design meets the TSD2GFS thermal guidelines.
