Taiwan Semiconductor Corporation S1JFSHMWG

Overview

S1JFSHMWG from Taiwan Semiconductor is a 1A, 600V standard surface-mount silicon rectifier diode in SOD-128 package, featuring glass-passivated junction, 30A surge rating, and 150°C max junction temperature; used in DC-DC converters and switching-mode inverters where compact high-voltage rectification is required.

For engineers reviewing the S1JFSHMWG datasheet, S1JFSHMWG pinout, S1JFSHMWG application, or S1JFSHMWG equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward voltage at 1 A (≤1.1 V @ 25°C), thermal resistance (R_θJL = 29 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance.

Technical Context

This single-die standard recovery rectifier operates with a 600 V V_RRM, supports continuous 1 A forward current, and withstands 30 A non-repetitive surge (8.3 ms half-sine). Its glass-passivated junction ensures stable performance under humidity stress per J-STD-020 MSL 1.

Thermal design relies on low junction-to-lead resistance (29 °C/W) when mounted on a 5 mm × 5 mm copper pad; reverse leakage remains ≤1 µA at 25°C and ≤50 µA at 125°C under rated VR, enabling reliable operation in industrial power supplies.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for S1JFSHMWG?

The S1JFSHMWG has a V_RRM of 600 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is validated under standard test conditions (T_A = 25°C). Designers must ensure system-level voltage transients remain within this limit plus appropriate derating margin.

Is S1JFSHMWG compatible with lead-free reflow soldering processes?

Yes, the S1JFSHMWG is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its MSL 1 classification per J-STD-020 eliminates pre-bake requirements. The SOD-128 package is rated for peak reflow temperatures up to 260°C, supporting standard IPC/JEDEC profiles without degradation of electrical or mechanical integrity.

What is the forward voltage (V_F) of S1JFSHMWG at 1 A and 125°C?

At 1 A forward current and 125°C junction temperature, the S1JFSHMWG exhibits a typical forward voltage of 0.85 V and a maximum of 0.95 V, as specified in the Electrical Specifications table. This lower V_F at elevated temperature reflects the negative temperature coefficient of silicon diodes and is critical for thermal stability analysis in high-ambient applications.

Does S1JFSHMWG have a defined junction-to-case thermal resistance (R_θJC)?

Yes, the S1JFSHMWG has an R_θJC of 30 °C/W, measured under standardized test conditions (mounted on a 5 mm × 5 mm Cu pad). This parameter enables accurate thermal modeling between the die and external heatsink interface, complementing the published R_θJL (29 °C/W) and R_θJA (82 °C/W) values for comprehensive thermal design.

How is polarity indicated on the S1JFSHMWG package?

Polarity on the S1JFSHMWG is indicated by a visible cathode band on the SOD-128 case body. Per the Mechanical Data section, this band marks the cathode terminal, which must be connected toward the higher-potential node in the rectification path. Correct orientation is essential to prevent reverse conduction failure and ensure proper circuit functionality.
