Product details
Overview
TSD3GFS from Taiwan Semiconductor is a 3A, 400V glass-passivated ESD-hardened general-purpose rectifier diode in SOD-128 package, featuring 0.96V forward voltage at 3A/25°C, 50A surge rating, and ≥8kV HBM ESD immunity per AEC-Q101-001 Class H3B - used for polarity protection in industrial power supplies and DC input stages.
For engineers reviewing the TSD3GFS datasheet, TSD3GFS pinout, TSD3GFS application, or TSD3GFS equivalent, key selection criteria include its 400V VRRM, 15°C/W junction-to-lead thermal resistance, SOD-128 mechanical compatibility, and verified 10kV IEC 61000-4-2 contact-mode ESD performance.
Technical Context
This single-die silicon rectifier operates with a maximum junction temperature of 175°C and supports continuous forward current up to 3A at ambient conditions, derating linearly above 75°C per the published derating curve. Its low 0.96V VF at rated current reduces conduction losses in high-efficiency 12–48V DC systems.
The device uses glass passivation for stable reverse leakage (≤1µA at 25°C, ≤6µA at 125°C) and achieves 18pF junction capacitance at 1MHz/4V, enabling stable switching behavior in moderate-frequency rectification applications up to ~100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in DC-blocking or reverse-polarity protection circuits |
| IF | 3 A - Continuous average forward current rating; determines usable power-handling capacity in steady-state rectification |
| IFSM | 50 A - Non-repetitive surge current (8.3ms half-sine); supports inrush current tolerance during power-up in capacitive-input supplies |
| VF @ 3A/25°C | 0.96 V - Forward voltage drop at full rated current; directly impacts conduction loss (Pcond ≈ 2.88W) and thermal design margin |
| RθJL | 15 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pad thermal path design without heatsink for ≤2.5W dissipation |
| ESD Rating | ≥8 kV HBM (AEC-Q101-001 Class H3B) - Confirmed robustness against human-body discharge events in assembly and field environments |
| Junction Capacitance | 18 pF @ 1 MHz / 4 V - Low parasitic capacitance minimizes high-frequency noise coupling and switching losses in SMPS front-end stages |
Pinout & Package
Package: SOD-128 - Surface-mount plastic package with matte tin-plated leads, 5mm × 5mm Cu pad thermal test board reference, UL 94V-0 rated molding compound, and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side in polarity protection; must withstand full system voltage during reverse bias |
| Cathode | Forward current exit point | Marked by visible band; ties to load/ground side; carries full output current and defines reverse-bias blocking node |
Key Features
| Feature | Design Value |
|---|---|
| ESD-hardened junction | ≥8kV HBM per AEC-Q101-001 Class H3B - eliminates need for external TVS in cost-sensitive industrial control inputs |
| Glass-passivated chip | Stable IR ≤1µA @ 25°C and ≤6µA @ 125°C - ensures long-term reliability under humid or high-temperature operating conditions |
| SOD-128 mechanical standard | JEDEC DO-221AD compliant footprint - enables drop-in replacement with industry-standard layout and reflow profiles |
| Low VF at high temperature | 0.85V @ 3A/125°C - maintains efficiency in thermally constrained enclosures without significant conduction loss increase |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L04 | 400V VRRM, 3A IF, but only 20A IFSM; no AEC-Q101 ESD rating specified | Lacks certified ≥8kV HBM immunity; unsuitable for ESD-prone industrial interfaces | Select TSD3GFS where field-level ESD robustness is required per AEC-Q101 or IEC 61000-4-2 |
| SB340 | 40V VRRM, 3A IF, Schottky architecture; lower VF (~0.45V) but limited to low-voltage use | Not rated for 400V reverse blocking; cannot replace TSD3GFS in high-voltage DC input protection | Choose SB340 only for ≤40V systems requiring ultra-low forward drop; not a functional substitute for TSD3GFS |
Compared with STTH3L04 and SB340, the TSD3GFS uniquely combines 400V blocking, 50A surge capability, and certified 8kV+ ESD immunity in a JEDEC-standard SOD-128 package - making it the only option among the three qualified for ruggedized industrial and automotive-grade polarity protection.

FAQ
What is the maximum repetitive peak reverse voltage rating for TSD3GFS?
The TSD3GFS has a maximum repetitive peak reverse voltage (VRRM) of 400 V, as confirmed in the Absolute Maximum Ratings table. This value is fixed for the TSD3GFS variant and distinguishes it from the 600V-rated TSD3JFS. Operation beyond 400V risks irreversible junction breakdown and must be avoided in all circuit designs using the TSD3GFS.
Does TSD3GFS meet automotive qualification standards?
Yes, the TSD3GFS is qualified per AEC-Q101-001 Class H3B for human-body model ESD, with ≥8 kV immunity. While it is not fully AEC-Q101 qualified across all stress tests, this specific ESD rating is explicitly validated and documented for the TSD3GFS in the official datasheet - supporting use in automotive body electronics where ESD robustness is critical.
What is the forward voltage drop of TSD3GFS at 3A and 125°C?
The TSD3GFS exhibits a typical forward voltage drop of 0.85 V at 3.0 A and 125°C, as specified in the Electrical Specifications table. This value is lower than its 0.96 V rating at 25°C, reflecting the negative temperature coefficient of silicon PN junctions - an important factor for thermal stability in high-ambient applications using the TSD3GFS.
Is TSD3GFS compatible with lead-free reflow soldering processes?
Yes, the TSD3GFS features matte tin-plated leads compliant with J-STD-002 for solderability and is rated for moisture sensitivity level 1 per J-STD-020 - meaning it can be subjected to standard lead-free reflow profiles (peak ≤260°C) without baking or special handling. This makes the TSD3GFS suitable for high-volume automated assembly lines using the TSD3GFS.
What package type does TSD3GFS use, and what are its key mechanical features?
The TSD3GFS uses the SOD-128 surface-mount package, defined by JEDEC DO-221AD Variation AD. Key mechanical features include UL 94V-0 flammability-rated molding compound, cathode band polarity indicator, 0.028g mass, and compliance with JESD201 Class 2 whisker resistance - all confirmed in the Mechanical Data section of the TSD3GFS datasheet.
