Product details

Overview

TSD3GFSH from Taiwan Semiconductor is a glass passivated, AEC-Q101-qualified single-die SOD-128 surface-mount rectifier rated for 400 V repetitive peak reverse voltage (V_RRM), 3 A average forward current (I_F), and 50 A surge current (I_FSM). It delivers low forward voltage (0.96 V at 3 A, 25°C) and high ESD immunity (≥8 kV HBM, ≥15 kV IEC 61000-4-2 air discharge), enabling robust polarity protection in automotive power rails.

For engineers reviewing the TSD3GFSH datasheet, TSD3GFSH pinout, TSD3GFSH application, or TSD3GFSH equivalent, key selection criteria include its 400 V V_RRM, SOD-128 thermal performance (R_θJL = 15 °C/W), 175 °C max junction temperature, RoHS/halogen-free compliance, and AEC-Q101 qualification for under-hood use.

Technical Context

The TSD3GFSH is a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced reliability and moisture resistance. Its SOD-128 package provides low thermal resistance to lead (15 °C/W) and supports automated placement per J-STD-002 solderability standards.

It operates across –40 °C to +175 °C junction temperature range and exhibits low leakage (≤1 µA at 25°C, ≤6 µA at 125°C) and low capacitance (18 pF at 4 V, 1 MHz), making it suitable for high-frequency switching and noise-sensitive DC power conditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum reverse blocking voltage before breakdown; defines safe operating margin in 24–48 V automotive systems.
I_F	3 A continuous - Average forward current rating at 75 °C PCB temperature; supports sustained load in compact power supplies.
I_FSM	50 A (8.3 ms) - Peak non-repetitive surge capability; handles inrush and load dump transients without failure.
V_F	0.96 V @ 3 A, 25°C - Low conduction loss reduces heat generation and improves efficiency in high-current paths.
T_J max	+175 °C - Enables operation in engine compartment environments without derating penalties up to ambient 125 °C.
R_θJL	15 °C/W - Efficient heat transfer to PCB copper pad; allows thermal design with minimal heatsinking on 5 mm × 5 mm Cu area.
C_J	18 pF @ 4 V, 1 MHz - Minimizes high-frequency coupling and EMI in fast-switching DC/DC converters.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-3EWH04-M3/5AT	Same SOD-128 package, 400 V V_RRM, but higher V_F (1.05 V @ 3 A) and lower I_FSM (40 A).	Lacks AEC-Q101 qualification and ESD ratings above 4 kV HBM.	Acceptable for non-automotive industrial use where cost sensitivity outweighs qualification requirements.
ON Semiconductor MUR340SFT1G	TO-277 package (not SOD-128), same 400 V/3 A rating, faster recovery (t_rr = 50 ns), but no AEC-Q101 or high-ESD data.	Requires PCB layout change; unsuitable for space-constrained automotive modules.	Preferred only when ultra-fast recovery is required and board real estate permits TO-277 footprint.

Compared with VS-3EWH04-M3/5AT and MUR340SFT1G, the TSD3GFSH uniquely combines AEC-Q101 qualification, ≥8 kV HBM ESD, SOD-128 footprint, and 175 °C operation-making it the only drop-in solution for thermally demanding, safety-critical automotive rectification where qualification and reliability are mandatory.

FAQ

What is the maximum junction temperature rating for the TSD3GFSH?

The TSD3GFSH has a maximum junction temperature (T_J) rating of +175 °C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive locations where ambient temperatures exceed 125 °C, provided thermal design maintains junction temperature below this limit. The TSD3GFSH achieves this via low R_θJL (15 °C/W) and glass passivation.

Is the TSD3GFSH pin-compatible with other SOD-128 rectifiers like the TSD3JFSH?

Yes, the TSD3GFSH shares identical SOD-128 mechanical dimensions, pinout, and mounting footprint with the TSD3JFSH. However, they differ electrically: TSD3GFSH is rated for 400 V V_RRM, while TSD3JFSH is rated for 600 V. Both use the same anode/cathode terminal configuration and marking orientation (cathode band), enabling direct PCB reuse with voltage derating consideration.

Does the TSD3GFSH meet automotive qualification standards?

Yes, the TSD3GFSH is fully AEC-Q101 qualified per revision C, including tests for temperature cycling, high-temperature operating life, and ESD per AEC-Q101-001 (HBM ≥8 kV). Its qualification documentation, test reports, and lot traceability are maintained by Taiwan Semiconductor and available upon request for TSD3GFSH production lots.

What is the forward voltage drop of the TSD3GFSH at 3 A and 125 °C?

The TSD3GFSH exhibits a typical forward voltage (V_F) of 0.85 V at 3 A and 125 °C, as specified in the electrical characteristics table. This value reflects reduced conduction loss at elevated temperatures due to silicon physics, supporting stable performance in hot environments without thermal runaway.

How is polarity indicated on the TSD3GFSH package?

Polarity on the TSD3GFSH is indicated by a visible cathode band printed on the molded SOD-128 body. Per JEDEC DO-221AD and TSC's marking diagram, the band aligns with the cathode terminal, which must be connected toward the load or ground side of the circuit. The device marking code "D3GFS" appears adjacent to the band.
