Product details
Overview
TSD3JFSH from Taiwan Semiconductor is a 600V, 3A glass-passivated ESD-hardened rectifier diode in SOD-128 package, featuring 50A surge rating, 175°C max junction temperature, and AEC-Q101 qualification for automotive-grade polarity protection and power conversion circuits.
For engineers reviewing the TSD3JFSH datasheet, TSD3JFSH pinout, TSD3JFSH application, or TSD3JFSH equivalent, key selection criteria include reverse voltage rating (600V), forward current (3A), ESD immunity (≥15kV air discharge), thermal resistance (RθJL = 15°C/W), and SOD-128 mechanical compatibility with automated placement.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-reliability DC power path management. Its glass-passivated junction ensures stable leakage performance across -40°C to +175°C, while low forward voltage (0.96V @ 3A, 25°C) reduces conduction loss in compact power supplies and battery protection circuits.
The SOD-128 package delivers enhanced thermal performance via low RθJL (15°C/W) and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards. Cathode band marking and matte tin-plated leads support reliable soldering per J-STD-002.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V, 3A, TO-277A package; higher RθJA (80°C/W) vs. TSD3JFSH's 70°C/W; VF = 1.15V @ 3A | Requires larger thermal pad area; less suitable for ultra-thin PCBs | Prefer TSD3JFSH where board space and thermal resistance are constrained |
| SB360-E3/5BT | 60V-rated Schottky; not voltage-compatible; VF = 0.65V but VRRM too low for 600V use | Only viable in low-voltage (<100V) applications; cannot replace TSD3JFSH in HV rectification | Select only if system VR < 80V and low VF is primary requirement |
Compared with STTH3L06S and SB360-E3/5BT, the TSD3JFSH offers superior thermal performance in compact SOD-128 form factor and validated automotive reliability-making it optimal for space-constrained, high-temperature, and safety-critical rectification roles where 600V blocking is mandatory.

FAQ
What is the maximum junction temperature rating for TSD3JFSH?
The TSD3JFSH has a maximum junction temperature (TJ) rating of +175°C, verified per AEC-Q101 stress testing. This allows operation in high-ambient environments such as engine compartments or sealed industrial enclosures. The TSD3JFSH maintains specified electrical parameters-including reverse leakage and forward voltage-up to this limit when thermal design adheres to the published RθJL = 15°C/W specification.
Is TSD3JFSH pin-compatible with TSD3GFSH?
Yes, TSD3JFSH and TSD3GFSH share identical SOD-128 package dimensions, pinout, and thermal characteristics-only the VRRM differs (600V vs. 400V). Both use the same footprint, cathode band orientation, and lead finish. Engineers may substitute TSD3JFSH for TSD3GFSH in designs requiring higher reverse voltage margin without layout changes.
Does TSD3JFSH meet automotive qualification standards?
Yes, TSD3JFSH is AEC-Q101 qualified, having passed all required stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TC), and human-body-model ESD (≥8kV). This certification confirms suitability for automotive powertrain, chassis, and body electronics where reliability under thermal and electrical stress is critical.
What is the forward voltage drop of TSD3JFSH at 3A and 125°C?
The TSD3JFSH exhibits a typical forward voltage drop of 0.85V at 3A and 125°C, with no maximum value specified in the datasheet. This represents a 11.5% reduction from its 25°C value (0.96V max), improving efficiency in thermally stressed operating conditions. The measured value is confirmed under pulse test conditions (PW = 0.3ms) per the official TSC datasheet revision B2312.
Can TSD3JFSH be used in surface-mount reflow processes?
Yes, TSD3JFSH is qualified for standard lead-free reflow soldering per J-STD-020. Its moisture sensitivity level is rated Class 1 (unlimited floor life at ≤30°C/85% RH), and matte tin-plated leads comply with J-STD-002 for solderability. The SOD-128 package withstands peak reflow temperatures up to 260°C, making it compatible with common Pb-free assembly lines.
