Product details
Overview
TSD3JFS from Taiwan Semiconductor is a 600V, 3A glass-passivated ESD-hardened rectifier diode in SOD-128 package, with 50A surge rating, 0.96V forward voltage at 3A/25°C, and ≥10kV IEC 61000-4-2 contact-mode ESD immunity-used for polarity protection in industrial power supplies and DC input stages.
For engineers reviewing the TSD3JFS datasheet, TSD3JFS pinout, TSD3JFS application, or TSD3JFS equivalent, key selection criteria include its 600V VRRM, 175°C junction temperature rating, SOD-128 thermal performance (RθJL = 15°C/W), and verified AEC-Q101 Class H3B human-body ESD robustness.
Technical Context
This device is a single-die, surface-mount silicon rectifier optimized for high-reliability DC input protection where transient overvoltage and electrostatic discharge are critical concerns. Its glass-passivated junction ensures stable leakage current (<1µA at 25°C) and low capacitance (18pF at 4V), while the SOD-128 package enables automated placement and meets JESD201 Class 2 whisker resistance.
The TSD3JFS operates across –40°C to +175°C ambient, with thermal derating defined by RθJA = 70°C/W on a 5mm × 5mm Cu pad. Its 1.1V max forward voltage at 3A/25°C and 0.85V typical at 3A/125°C support efficient conduction in thermally constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in 400–600V DC bus applications. |
| IF | 3 A - Continuous forward current rating; supports sustained load handling without thermal runaway under proper PCB heatsinking. |
| IFSM | 50 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients in power entry circuits. |
| VF @ 3A, 25°C | 0.96 V max - Forward voltage drop determines conduction loss and self-heating; enables <1.2W dissipation at full rated current. |
| TJ max | +175°C - Maximum junction temperature; allows operation in high-ambient environments such as enclosed industrial enclosures. |
| CJ | 18 pF @ 1MHz, 4V - Junction capacitance impacts high-frequency switching noise and EMI filtering behavior in rectifier front-ends. |
| ESD Rating | ≥10 kV contact mode (IEC 61000-4-2) - Confirmed immunity level for handling and board-level ESD events without parametric shift. |
Pinout & Package
Package: SOD-128 - Surface-mount, flat-lead plastic package with cathode band marking, 5.00 mm × 2.70 mm footprint, 1.20 mm height, UL 94V-0 rated molding compound, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input side of polarity protection circuit; must be routed with adequate copper area for thermal relief. |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by visible band; connects to protected load side; reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| ESD-hardened junction | Rated ≥10 kV contact-mode per IEC 61000-4-2-reduces field failure risk in unshielded assembly lines and end-user environments. |
| Glass-passivated chip | Stabilizes leakage current (≤1 µA @ 25°C) and prevents moisture-induced parameter drift over lifetime. |
| SOD-128 thermal design | RθJL = 15°C/W enables direct heat transfer to PCB copper-no external heatsink needed for ≤3A continuous use. |
| Automated placement compatibility | Standard tape-and-reel packaging (14,000 pcs/reel) and lead coplanarity meet IPC-7351 requirements for pick-and-place reliability. |
| Halogen-free & RoHS | Complies with EU RoHS Directive 2011/65/EU and JEDEC JS709C-supports green manufacturing and export compliance. |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) Supply |
|---|---|
Use Scenario: DC input stage of programmable logic controllers (PLCs) exposed to 24–48V rail reversals and load dump transients. IC Role / Device Role / Timing Role: Polarity protection rectifier-blocks reverse connection while conducting forward current with minimal loss.

IC Role / Device Role / Timing Role: Single-diode protection element placed upstream of LDOs and microcontrollers. Use Value: AEC-Q101 Class H3B ESD rating (≥8kV HBM) and JESD201 Class 2 whisker resistance meet automotive reliability standards. |
| Telecom Remote Radio Unit (RRU) Power | Renewable Energy Charge Controller |
Use Scenario: Input rectification in outdoor-mounted RRUs subject to lightning-induced surges and wide ambient temperature swings. IC Role / Device Role / Timing Role: High-voltage, high-ESD rectifier in DC power entry path before DC-DC conversion. Use Value: 18pF junction capacitance minimizes RF coupling into sensitive RF sections; 175°C TJ rating accommodates desert or rooftop deployments. | Use Scenario: Battery-side polarity guard in solar charge controllers connecting PV arrays to 12/24V battery banks. IC Role / Device Role / Timing Role: Unidirectional current gate preventing battery discharge through PV panels at night. Use Value: Low 0.96V VF reduces conduction loss in high-current charging paths; SOD-128 footprint fits compact PCB layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IF, but VF = 1.3V @ 3A - 36% higher conduction loss; TO-277 package (larger footprint, higher RθJA). | Higher thermal resistance (RθJA ≈ 90°C/W) requires larger copper area or forced cooling in same layout. | Choose when legacy TO-277 footprint compatibility is required and higher VF is acceptable. |
| MBR360FCT | 60V VRRM, 3A IF, Schottky architecture - lower VF (0.52V), but unsuitable for >100V reverse stress. | Cannot replace TSD3JFS in 400–600V applications due to catastrophic reverse breakdown below rated voltage. | Only viable in low-voltage DC systems where reverse voltage never exceeds 60V. |
Compared with STTH3L06S and MBR360FCT, the TSD3JFS uniquely balances 600V capability, low VF, SOD-128 space efficiency, and certified ESD robustness-making it optimal for compact, high-reliability DC input protection where voltage, thermal, and ESD margins are simultaneously constrained.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for TSD3JFS?
The TSD3JFS has a VRRM of 600 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2309). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is strictly validated for the TSD3JFS variant-not extrapolated from TSD3GFS or other family members.
Does TSD3JFS meet AEC-Q101 qualification?
Yes, the TSD3JFS is rated Class H3B per AEC-Q101-001 Human Body Model (HBM), with ≥8 kV ESD immunity. This qualification is explicitly stated in the "Immunity to Electrical Static Discharge" section of the datasheet and applies to the TSD3JFS part number as shipped, not inferred from family-level testing.
What is the forward voltage (VF) of TSD3JFS at 3A and 125°C?
At 3.0 A forward current and 125°C junction temperature, the TSD3JFS exhibits a typical forward voltage of 0.85 V, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects reduced conduction loss at elevated temperatures compared to room-temperature operation.
Is TSD3JFS compatible with lead-free reflow soldering processes?
Yes, the TSD3JFS uses matte tin-plated leads compliant with J-STD-002 and is rated for lead-free reflow soldering. Its moisture sensitivity level is J-STD-020 Level 1, meaning it can be stored indefinitely at ≤30°C/85% RH without baking prior to assembly-confirmed in the Mechanical Data section of the datasheet.
What is the thermal resistance from junction to ambient (RθJA) for TSD3JFS?
The TSD3JFS has an RθJA of 70°C/W when mounted on a standard 5 mm × 5 mm copper pad test board, as documented in the Thermal Performance table. This value assumes natural convection and is used for initial thermal design; actual performance depends on PCB copper area, layer count, and airflow.
